Effects Send Matrix (Cell A11)
The Effects Send Matrix option provides a method of integrating digital
effects devices into the switcher mix/ effects system. Up to two send
channels can be used to route the A video, key 1, or key 2 from an M/ E to
and from an external digital effects system.
This option comes in the form of an Effects Send Matrix Module which
installs in the front switcher frame bay.
Secondary Wipe Generators
An optional Secondary Wipe Generator for both Mix/ Effects provides a
second wipe pattern for each of the M/ E systems. With this option
installed, two independent wipe patterns are allowed within each M/ E.
The output from the Secondary Wipe Generator can be mixed or non-
additively mixed with the output from the primary wipe generator to
create novel wipe patterns.
This option also allows the Preset wipe pattern to differ from the transition
wipe pattern. It can also be used as an additional mask source and a matte
generator modulator within each M/ E.
The Secondary Wipe Generator Modules are sub-modules which mount
onto the Mix/ Wipe Modules in each M/ E.

Physical Description
Physical Description
Model 2200 Series electronic circuitry is contained on circuit modules in the
switcher frame, effects frame, and control panel.
In this manual and in other related documents, the circuit modules will be
referred to by the names and assembly numbers printed on them.
Control Panel
The control panel is the operator interface for the Model 2200 system and
provides all operator controls for the switcher and effects systems.
Through the control panel, the operator performs all actions via
mechanical buttons and controls, or through software controlled menus
and soft button adjustments. The control panel provides the data links to
both Frames.
Switcher Frame
all of the signal processing modules along with some control processor
modules.
The Head-of-State (HOS) processor and all M/ E processors reside on two
Control Processor modules in Bay A (front bay) of the frame. Control
Processor 1 contains the HOS processor which supervises the state of the
switcher, handles communication with the control panel and controls the
video hardware. The M/ E 1 processor also resides on this module.
The Control Processor 2 contains the circuitry for communication with the
editor, tally expansion and other remote control. The M/ E 2 processor is on
this module.
Since each M/ E has its own processor, failure of the HOS processor does
not shut down the entire switcher. Individual M/ Es can continue to
operate independently, although in a degraded capacity (cuts, mixes and
fade- to-black continue to operate).
The control panel communicates with the switcher frame over two RS-422
data links, one per M/ E. Both of the links is contained within a single cable
that may be up to 1000 feet long.

Section 2 — Installation
WARNING
Electrical potential is still applied to some internal components even when
the power switch/breaker is in the off position.To prevent electrical shock
when working on this equipment, disconnect the AC line cord from the AC
source before working on any internal components. A residual voltage may
be present immediately after unplugging the system due to large power
supply capacitors discharging. Wait thirty seconds to allow capacitors to
discharge before working on the system.
WARNING
The switcher frame weighs approximately 175lbs. (67 Kg.) when fully
configured. Provide appropriate equipment to support the frame during
installation.
Do not lift the control panel by the lid.The lid could open causing the unit to
fall creating a hazard to personnel and/or damage to the equipment.
WARNING
The Switcher Frame Power Supply assembly exhibits high leakage (fault)
currents due to the EMI suppression filter system.This power supply chassis
must be connected to earth ground via the ground wire provided in the AC
input cord. An additional ground lug is provided on the rear of the power
supply chassis for supplementary grounding purposes.
CAUTION
To avoid static damage to sensitive electronic devices, protect the Model 2200
Digital Switcher from static discharge. Avoid handling switcher modules in a high
static environment. Touch the switcher frame before you remove any modules.
This helps ensure that any potential difference between your body and the frame
is dissipated. If you handle the modules or make any repairs to them use a
grounding strap and grounded equipment.

Switcher Frame Installation
NOTE: The switcher frame must be installed before either of the power supplies.
When planning your installation, ensure that the frame will be installed high
enough in the equipment rack to allow 7 rack units for the installation of the Frame
Primary Power Supply (and another 7 rack units for the optional redundant Power
Supply, if purchased) below it.
To allow the use of extender modules and access for other maintenance, sufficient
room should be allowed in front of the equipment rack (≥41 inches, 1.05 0 M.).
Sufficient room should also be allowed in the rear of the rack for access to cables and
the exhausting of cooling air.
The switcher frame mounts in a standard 19-inch (48.3 mm) wide
equipment rack. It is installed in the rack from the front and secured at the
front edges of the frame with screws (not provided by GVG). Its Power
Supply mounts below it in the rack on slide rails. The procedure for
installing the Power Supply follows the frame installation procedure.
To install the frame in the equipment rack, read the following precautions,
WARNING
The Model 2200 switcher frame weighs approximately 175 lbs (67 Kg.) when
fully configured. Provide appropriate equipment to support the frame during
installation.
When the switcher frame and Power Supply are installed, the equipment rack
is top heavy and could topple. Ensure that the equipment rack is attached
solidly to the floor/building to prevent tipping when the frame and Power
Supply are installed.
When lifting the frame into place in the equipment rack, it is recommended
that a mechanical lifting device be used.
Ensure that the bottom plate of the frame is protected from damage while the
frame is being lifted into the equipment rack.
NOTE: The switcher frame is shipped with a protective metal plate on the bottom.
Leave the plate in place to protect the power cables until the frame is mounted in
the rack.

Section 2 — Installation
Switcher Frame Power Supply Installation
The Primary Power Supply must be mounted immediately below the
switcher frame in the rack. If you are installing an optional Redundant
Power Supply, it must be located immediately below the Primary Power
Supply. Verify that you have allowed enough rack space (7 rack units per
Supply) before proceeding.
WARNING
To reduce the risk of electric shock, do not perform any servicing other than
that contained in the operating instructions unless you are qualified to do so.
To install the Switcher Frame Power Supply in the equipment rack, refer to
1. Ensure that the Primary and Redundant Power Supplies are
disconnected from all power sources.
2. Locate the installation kit containing the power supply assembly slide
mounts and hardware. The installation kit consists of the following:
a. Slide Mounts
b. Mounting Hardware
3. Measure the location of the slide sections mounted on the power
supply chassis to determine the height at which the stationary sections
of the slides are to be mounted in the rack.
NOTE: The Primary Power Supply will be attached to the bottom of the switcher
frame by eight captive screws. It must be installed so that it is touching the bottom
of the frame.
4. Verify that the screws holding the chassis sections of the slides to the
power supply chassis are securely tightened.
5. Mount the rack sections of the slides to the front and back of the rack
and secure them in place with the appropriate screws as illustrated in
the inside of the rack rail. On threaded rails, run short pan head screws
from the inside. On unthreaded rails, run flat head screws (with nuts)
from the outside. This results in the power supply being flush with the
frame; plus allowing for the proper mating of the electrical connectors
in back. It may be necessary to adjust the length of the rear brackets,
depending upon the depth of the rack assembly.

Mask Draw Tablet Installation
The Mask Draw feature (requiring version 5.2 software and new Frame Store and
Mask Store hardware) allows you to use a graphics tablet (connected to the
switcher Control Panel) to customize existing masks or to create new ones.
Using the Force Mask mode, you can add to a key, or using the Inhibit Mask mode,
you can subtract from a key.
For example, one use of Mask Draw is the ability to draw an irregularly shaped
“garbage mask.” Draw a custom-shaped mask around an object using Force Mask,
and turn “foreground” on. Use this tool instead of keying the object out.
NOTE: For the Model 2200, mask draw requires the new Frame Store module (064814-
04). The Mask Draw feature works with the Model 2200 by feeding the mask into the key
channel.
For the Model 4000, mask draw requires the new Mask Store Option for full functionality,
or the new Frame Store module for Mask Store using the key channel.

Analog Output
The optional Analog Output Module (slot C15) provides component
analog monitor outputs for M/ E 2 program and switched preview. These
outputs are designed for monitor use only and should not be used as on air
outputs.
There are two DAC Mezzanine boards on the Analog Output Module; one
providing the Program analog output and the other, the Preview analog
output. There are ten Color Difference or RGB formats to choose from as
the analog output. Output format is determined by the customer by setting
jumpers on the Analog Output Module and the mezzanine boards. Gain
adjustments must also be made for accurate output levels.
Analog Output Modules leave the factory set at RGB .700V, No Setup, and
narrow RP125 blanking. To change to a different standard, perform the
following steps:
1. Remove the Analog Output Module from the rear Signal Processor
Frame, and place it on a flat, static-free surface.
2. Locate jumper J17, on the right hand side of the Analog Output Module
immediately below TP7. Set the jumper setting to the desired blanking
width of the converted video output. When set to RS-170 (wide
blanking), blanking edges are placed as in the RS-170 specifications for
60 Hz systems or for the CCIR 470-2 recommendation for 50 Hz
systems. When it is set to RP-125, blanking is active from end of active
video (EAV) to start of active video (SAV) data words, inclusive, as
described in SMPTE recommended practice RP-125.
3. Locate jumper J16 on the Analog Output Module, and select the
appropriate Setup (54 mV) or No Setup setting for your system’s
desired analog outputs. Note that this setting is common to both
program and preview outputs. Whatever is chosen for one applies to
both.

Section 2 — Installation
1. Place the Analog Output Module on the I/ O Module Extender
(064834), and select 100% Color Bars as the Program and Preview
switcher output. (You may use the internal signal for this adjustment
which is accessible through the Configuration [INPUTS] menu.)
2. The gain adjustment trimpots are accessible with the DAC mezzanines
installed on the Analog Output Module. Connect a waveform monitor
or oscilloscope to the Analog Output(s). Terminate the scope or
monitor’s inputs in 75 Ohms. A component waveform monitor is
convenient in that all three output channels can be observed
simultaneously, but it is only necessary to observe one at a time.
3. Adjust the gain controls to match the waveform for the desired format
NOTE: In RGB formats, the gain controls are somewhat interactive. For best
results, adjust Y gain while observing green output such that the white color bar
is at specified level. Then observe red output and adjust R-Y gain for equal level
bars having red content; similarly, observe blue output and adjust B-Y gain for
equal level bars.
Effects Send Option
The Effects Send option consists of the Effects Send Module which resides
in slot A11. When the effects send is used, the Aux Bus outputs of Serial
Output Module 2 (slot B11) become the outputs of the Effects Send option.
This allows A video and key signals (any two signals) in an M/ E to be
routed outside of the switcher for processing by external devices and then
brought back into the same M/ E for mixing and output. The Effects Send
functions require software set ups in the Configuration menus (See
Section 3 of the Reference Manual).

Chroma Keyer Option
Chromatte™ Advanced Chroma Keyer
You may install one Chromatte™ Chroma Keyer to each M/ E to add
internal 4:2:2 chroma keying functions to Keyer 1 and Keyer 2. Each option
includes a Chroma Key Carrier Module with a mezzanine module. The
Chroma Keyer for M/ E 1 slides into slot A3 and the M/ E 2 Chroma Keyer
slides into slot A16. To configure your Keyer option refer to the menus for
the Chroma Keyer in Section Three of the Operators Manual. Any serial
digital input may be used for 4:2:2 chroma keying from the key bus. Analog
component video may be used for 4:4:4 chroma keying with the Analog
Component Chroma Keyer Input Modules option. There is a separate front
panel gain control for each of the input BNC connectors.
BORDERLINE Key Edge Generator Option
The Borderline® option consists of one mezzanine module for one keyer.
This option module mounts on the Keyer Carrier where the Borderline is
desired. Up to four Borderline options may be installed on the Keyer
Carriers; one for M/ E 1 Keyer 1 (Slot A5), M/ E 1 Keyer 2 (Slot A6), M/ E 2
Keyer 1 (Slot A13), M/ E 2 Keyer 2 (Slot A14).
To install a Borderline Module, remove the designated Keyer Carrier
carefully, and place it on a static free surface. The Borderline Mezzanine
installs in the top location of the module above the Keyer Mezzanines as
illustrated in Figure 2-15.
1. Line up the four 50-pin connectors on the Borderline mezzanine with
the matching connectors on the Keyer Carrier. Be sure the pins are lined
up properly before seating the mezzanine (look between the mezzanine
and the Carrier). Push down firmly to seat the mezzanine to the Carrier.
Check that no pins are bent or outside of the connectors.
2. From the solder side of the Carrier, attach the mezzanine to the module;
install the four screws into the metal spacers on the mezzanine, and
carefully reinstall the Keyer Carrier into the frame in its proper slot
location.
NOTE: For best mechanical fit, Mezzanine modules should always be removed by
unscrewing from the solder side of the Carrier, not from the component side of the
Mezzanine.

Section 2 — Installation
Address Switches — Set the address of the Remote Aux Panel (0 through 31)
using the switches marked PANEL ADDRESS on the right rear of the panel
Switches 32 and 64 must be in the OFF position. It may be useful to
maintain a record of each Remote Aux panel address.
NOTE: Each panel must have a unique address. Setting the same address for two
or more panels will cause the entire Remote Aux system to malfunction.
Bus to be Controlled (Bus Enable) Switches — The 1-RU and 2-RU panels have
eighteen switches labeled BUS TO BE CONTROLLED. These set which
Aux Bus is controlled by the panel. Only one of these switches may be ON.
The 3-RU panel has eighteen switches labeled BUS ENABLE. These set
which Aux Buses can be controlled by the panel. Turn the switch ON for
each Aux Bus to be controlled. Any combination of the eighteen switches
can be turned ON. The functioning of the buses that have the switches
turned OFF depends on the position of the DEL LOCK switch (see below).
The last eight switches (6A through 9B) must be set to OFF.
NOTE: Two or more panels can control the same Aux Bus; however, if the same
bus is selected on more than one panel, the panel with the highest address will
control the bus.
Delegate Lock Switch — On the 3-RU panel, the DEL LOGIC switch controls
the functioning of the Aux Buses that are not selected:
DELLOCK Switch OFF: If a BUS ENABLE switch is OFF, the associated
Delegate button on the panel can be selected and the source button
selected for that bus will light but cannot be changed.
DEL LOCK Switch ON: The Delegate button on the panel cannot be
selected if its BUS ENABLE switch is OFF.
NOTE: The DEL LOGIC switch is not used on the 1-RU and 2-RU panels.
Force High Tally Switch — On the 1-RU panel, the FORCE HIGH TALLY
switch forces the ON AIR lamp on at all times.
On the 2-RU and 3-RU panels, the FORCE HIGH TALLY switch disables
the low tally condition. The lamps will be on bright whether the bus is on
air or not.
Test Mode Switches — These switches run diagnostics and program the
joystick override. For normal operation set all four TEST MODE switches
to OFF. Information on the test mode switches can be found in the Remote
Aux Panel Manual TP0699-01.
Chop Enable Switch — Enables and disables the chop mode

es as listed in Table 2-6.
When Mode 1, 2, or 3 (Iso Tally) is selected, the switcher tallies only the
inputs that contribute to the output of the corresponding M/ E.
When Mode 4 (Individual Bus Iso Tally) is selected, the remaining six
banks of switches on the board (INDIVIDUAL BUS ENABLES 1—48) select
the switcher’s internal buses to be used as tally sources (see Table 2-4). For
example, with the Bus Enable switches set for buses 35 and 36 ON, if an
input were selected on bus 35 or 36, its corresponding relay would close.
The same input chosen on other buses would cause no relay closures. It is
possible to tally as many buses as desired simultaneously. Table 2-4 shows
the switch settings for each of the buses in Mode 4.

Status Terminal Connections
The Status Terminal connector on the rear of the control panel allows the
connection of a VT-100 (type) terminal to be connected to the Model 2200.
The terminal is used to monitor system status and for maintenance
purposes.
1. Connect a cable between the input of a VT-100 (type) terminal and J3
(Status Terminal connector) on the rear of the control panel. The
connector (J3) on the rear of the control panel is a standard RS-232
configuration via a DB-25 connector with the following pin-outs:
■
■
■
■
Pin 1 — Protective Ground
Pin 2 — TxD (From the Terminal)
Pin 3 — RxD (To the Terminal)
Pin 7 — Signal Ground
2. Ensure that the baud rate and other parameters of the Model 2200 given
below match the baud rate of the terminal. See the Owner’s Manual of
the terminal in use to determine or set the baud rate of the terminal.
Also be sure the terminal is set to “Newline Off” or “No Newline”.

Cable Connections
Input Signal Connections (Video and Key)
The Model 2200 allows up to 32 video/ key inputs to be connected. These
inputs are connected to a Serial Digital Module at the rear of the frame.
Inputs are configured in the soft menus.
Component analog inputs can be connected to the optional Chroma Key
Input Module.
NOTE: Grass Valley Products does not supply cables or terminators. These must
be obtained from other suppliers.
Serial Digital Video Connections
The serial digital inputs require the use of 75Ω coaxial cables. The use of
75Ω BNC connectors is recommended but not required. Facilities with
existing cables with 50Ω connectors on 75Ω cables need not change their
connectors. However, with the use of 50Ω connectors there is the
possibility of some errors occurring in the serial data stream.
The maximum length of serial digital cables should not exceed 225 meters
(738 feet). Fiber optic distribution and transmission is recommended for
runs longer than 225 meters.
Connect serial digital video sources to the Serial Input Modules in Slots C7,
C12-C14 as required for your facility. Inputs are loopthrough; be sure to
terminate each input with a 75Ω termination.

DPM Configurations
Digital Picture Manipulators (DPMs) are external video devices connected
to the switcher. In this discussion, reference is also made to DPM levels,
which are E-MEM levels into which DPM-associated information is
learned. The combined system capabilities of the switcher and DPMs
depend on:
■
■
■
The video connection
The capabilities of the DPM
The control connection
It is not necessary to have a control connection from the switcher to a DPM;
however, the highest level of system integration is achieved where there is
a control connection.
The Video Connection (Aux Buses and Return Inputs)
A normal video signal path consists of an Aux Bus output from the
switcher feeding a DPM input and the DPM output returned to a switcher
input which is mapped to a switcher source select button.
The video path through a DPM introduces a video delay into the system.
For example, Kaleidoscope introduces a 2-field video delay. It is most
important that this delay be set correctly in the DPM Setup menu if Effects
Send is to be used.
NOTE: If the video delay is not set correctly, there will be a glitch in the video upon
entering Effects Send mode.
There are four steps in configuring the video path:
■
■
Aux buses are assigned to DPMs using the DPM Map Aux Bus menu
Return input connections are configured using the DPM Map Inputs
menu
■
■
The mapping of a return connection to a crosspoint is done using the
Configuration/ Map Inputs menu
The video delay is set using the DPM Setup menu

Section 2 — Installation
The system defaults to all Aux Buses being part of the [MISC] E-MEM level.
When an Aux Bus is configured for use with an external DPM, its settings
are no longer saved in the [MISC] level but are saved in the relevant [DPM]
level when an E-MEM register is learned. Information (such as Aux Bus
crosspoint selection) is learned for each DPM on separate E-MEM levels.
In cases where it is not desirable to have an Aux Bus selection learned or
recalled on the [MISC] level, it is possible to configure the Aux Bus to a
[DPM] level (such as [DPM 4]) and never enable that level. An example
would be if the Aux Bus were controlled by a Remote Aux panel.
DPM Capabilities (Fixed and Pooled)
The characteristics of the DPM are configured in the DPM Setup menu. The
first choice to be made is selection of [DPM TYPE] from NONE, KSCOPE, KRYSTAL,
or OTHER FIXED.
The [DPM TYPE] of NONE indicates that there is no external DPM device used
for the particular DPM level. However, it can also be used for cases where
Aux Buses are assigned to a DPM level, but there is no physical device, no
return signal, and no control connection (for example, an Aux Bus
dedicated to feeding a video monitor).
Both KSCOPE and KRYSTAL are selections for pooled devices.
A pooled device is one which provides acquisition of logical channels from
a pool of physical channels.
Kaleidoscope is a pooled device. As an example, consider a Kaleidoscope
having 5 physical channels named A, B, C, D, and E. The pooled channels
are shared by different users. A user may build a Kaleidoscope effect using
3 channels. On one day he may acquire physical channels C, D, and E as
logical channels 1, 2, and 3; on another day he may acquire physical
channels B, C, and D as logical channels 1, 2, and 3. The same effect will
perform identically on both configurations since the operator’s view of the
system is the logical arrangement of channels (1, 2, and 3), not the physical
channels used.
In systems with multiple DPM channels, it is desirable to have a
predictable relationship between Aux Buses and DPM channels (for
example, Aux Bus 1 feeding DPM channel 1, Aux Bus 2 feeding channel 2,
and so on) and to have a particular switcher crosspoint button always
select the same DPM channel return input. For a fixed device (such as the
DPM-700) this relationship is achieved by cabling alone. For a pooled
device, such as Kaleidoscope, the Model 2200 achieves predictable DPM
channel routing by maintaining an extra level of mapping between
physical and logical DPM channels. This mapping, termed Switcher Input
Routing and Switcher Output Routing, is discussed on the following page.
2-54

Cable Connections
For [DPM TYPE] of OTHER FIXED or NONE (DPMs which are not pooled and do
not have Input and Output Routing), the [CHANNEL ROUTING] selection
should be OFF.
Kaleidoscope changes its logical-to-physical channel mapping, depending
on the order in which channels are acquired from its pool. Switcher output-
routing maps a physical Aux Bus to a logical Aux Bus so that the logical
Aux Bus number corresponds with the DPM’s logical channel.
The Aux bus button selection made on the switcher control panel is always
a logical Aux Bus; however, unless Kaleidoscope is connected, Logical Aux
Bus 1 always corresponds to Physical Aux Bus 1, etc. (The current mapping
of physical-to-logical DPM channels is displayed in the DPM Map Inputs
menu.)
It should be noted that the switcher supports only one pooled device. Also,
the pooled device must be cabled so that the first physical Aux Bus is
connected to the first physical channel. In the example in Figure 2-26,
Physical Aux Bus 1 is connected to Kaleidoscope Physical Channel A, Bus
2 to Channel B, and so on.

Section 2 — Installation
For a particular studio session, three Kaleidoscope channels could be
acquired from the pool in the order D, E, A, which would be logical
channels 1, 2, 3. This mapping information is passed from the DPM to the
switcher via the control connection. Switcher output routing ensures that
the logical channels 1, 2, 3 appear to the user on logical Aux Buses 1, 2, 3
and switcher input routing ensures that DPM logical channels 1, 2, 3
appear on the crosspoints configured for these logical channels. For the
above configuration, the selection of [CHANNEL ROUTING] in the DPM Setup
menu should be set to BOTH.
There are circumstances where output routing is not desirable. For
example, the DPM may have more than 5 channels. In that case, a router or
patch panel may be inserted between the switcher and Kaleidoscope
menu selection for [CHANNEL ROUTING] in the DPM Setup menu should be set
to SWR IN. This still provides the return video from the switcher being on a
consistent crosspoint.

Control Connection
Three forms of control connection to the DPMs are supported. These are
■
■
■
CPL (Control Point Language)
PBusII (Peripheral Bus II)
GPIs
Control Point Language — CPL is the communication protocol used to
couple the switcher and Kaleidoscope. One of its uses is to convey the
physical-to-logical channel mapping information described previously. It
is also used for run control of effects, Aux Bus selection (including front/
back switching) and tally.
When [DPM TYPE] is set to KSCOPE in the DPM Setup menu, CPL is
automatically invoked. [PORT ASSIGN] must be set to PORT A1.
The [AUX BUS CONTROL] selection has a choice of DPM or SWITCHER. In normal
use with Kaleidoscope, this should be set to DPM. With this setting, when a
source button is selected on the Kaleidoscope panel, that source button is
also selected on the switcher for that Aux Bus, and vice versa. So an effect
running on Kaleidoscope can cause the switcher to select different
crosspoints. This is the mechanism used to achieve front/ back switching.
If [AUX BUS CONTROL] is set to SWITCHER, any CPL requests to change
crosspoints on an Aux Bus are ignored and Kaleidoscope is unable to
change sources when running an effect.
All control connections have an associated control delay. For Kaleidoscope
using CPL, this delay is 6 fields which is selected automatically.
Peripheral Bus II (Port A3 Only) — PBusII is used for run control of effects
using triggers. With current software, PBusII triggers are learned into the
[MISC] E-MEM level. For example, when using PBusII as the control
connection for a DPM-700, the following should be set in the DPM Setup
menu:
[PORT ASSIGN] = NONE
[CHANNEL ROUTING] = OFF
GPIs — Both input and output GPIs may be used as triggers as part of the
control interface between the DPM and switcher. Depending on the nature
of the DPM, GPIs can be used for effect recall and run control, source
selection, and tally information.

Section 2 — Installation
GPI Connections
The four GPI connectors on the rear panel of the switcher frame provide
eight input and eight output GPI connections. See Table 2-14 These
connections provide a variety of user-assignable GPI applications such as
remote control of Auto Transitions, DSK mix, Fade-to-Black Transitions
and other selected functions. Refer to “External Interface Setup” later in
this section for defining GPI inputs.
NOTE: It is important that the shields of the GPI cables be attached to the ground
lugs as shown in Figure 2-31.
GPI Inputs
GPI inputs are opto-isolators. These pairs of input connectors are
numbered 1 through 8 with a chassis ground connection on the bottom
and +5V connection on the top end of each connector module. To
trigger the GPI input, a DC voltage must be applied across the pair of
terminals for that input. Voltage must be between 4V and 24V, either
polarity. When the device used to trigger this input has a pair of relay
contacts available, the following wiring connection is recommended
(Input 6 shown in the following example).
Connect the appropriate GPI DC input signals to the GPI INPUTS
connectors TB1 and TB2. See Table 2-31
GPI Outputs
Each GPI output consists of pairs of connections on the rear of the
frame, which are connected to an isolated pair of relay contacts (SPST;
normally open). These pairs of output connectors TB 3 and TB 4 are
numbered 1 through 8 with a chassis ground connection on both ends
of each connector module. These relay connections are rated at 500mA
(peak) for voltages not to exceed 30 volts peak (AC or DC) with respect
to chassis ground.
Connect the appropriate GPI output connections to GPI OUTPUTS
connectors TB3 and TB4. Record these output connections for use by
the operator when attaching the triggers to E-MEM recalls.

Remote Aux Connections
The Remote Aux Control Panel consists of three parts:
■
■
■
Remote Aux Panel Assembly
Power supply with power cord
Communications bus cable connector
NOTE: Due to limited access at the rear of the Remote Aux Panel after it is
installed in the rack, it is recommended that the communications cable and power
supply cord be connected and the DIP switches on the rear of the panel be set before
the panel assembly is installed in the rack.
Cable Installation
A Remote Aux cable connector is provided with each panel. See Figure 2-32
for connector illustration. This connector must be applied to a shielded
twisted-pair control cable with a D connector on the opposite end. The D
connector of the cable will later be plugged into the rear of the switcher
frame.
CAUTION
Do not plug the D connector in at this time. If power is applied to the switcher, the
cable line drivers in the switcher may be damaged.
The other end of the cable will be plugged into the Communications Bus
connector on the rear of the Remote Aux Panel using the supplied
connector. Any additional panel(s) will be connected to the previous panel.
Keep in mind that the total length of the cable must not exceed 1000 feet
(320 M).
Place the D-connector end of the cable so that it will reach J4 (AUX BUS
CTL) on the Communication I/ O Module Slot C10.
Lay the cable from the switcher frame to where the first Remote Aux Panel
will be. Allow enough cable to reach the control panel connector, and about
3 feet (1 meter) extra, then cut the cable and strip the wires.

Connector Installation
The connector that plugs into the Remote Aux Panel has screw clamps to
into the appropriate holes and screw down the clamps. If there is another
control panel, the cable to the next panel must also be inserted into this
connector. The D connector on that cable must be cut off, and the wires for
the next panel must be stripped and inserted into the same holes before the
screws are tightened. Make sure the polarity is correct. Refer to Figure 2-18

System Timing (13.5 MHz, Serial I/O only)
The Model 2200 switcher has timing compensation to adjust an analog
reference signal not in time with the serial inputs. The controls may also
offset the position of the serial inputs within the timing window to
minimize the delay through the switcher, for example. Timing is adjusted
with the FINE, MEDIUM and COARSE rotary switches on the front of the
064801 Sync Generator Module located in Slot A9 in the top of the front A
Bay of the switcher frame.
These controls move the timing of the whole switcher - the output timing
and the input timing window - relative to the analog reference to the
The range of each control is as follows:
■
■
■
FINE: 296 ns total (18.5 ns per step)
MEDIUM: 4.74 µS total (296 ns per step)
COARSE: 75.8 µS total (4.74 µs per step)
Set the controls to the nominal center shown below:

Output Modules
There are three types of output modules available: Serial Digital Output,
Analog Output, and Timed Aux Output.
Serial (Digital) Output Modules (064821)
The Serial Output Modules convert the output signals from balanced
(differential) to unbalanced (coax) mode
Analog Output Module (064819)
The Analog Output Module is used to output the M/ E 2 program and
switched preview to monitors.
Timed Aux Output Module (064852) (Slot C16 and 17)
The basic function of the Timed Aux Output Module is:
■
Generate aux buses 3A through 5B
There are eight identical channels on the module but only six are used. In
one typical channel, the aux bus signal arrives from the Crosspoint
Module. The signal is de-serialized, descrambled, and presented to a
RP-125 decoder ASIC.
The ASIC is used in a standard fashion to re-synchronize and demultiplex
the signal. The timing signal is also used to provide delay information to a
pair of HSP–9501 delay lines. The delayed Y and C components of the
signal are multiplexed together by RP–125 encoder. Finally, the signal is
scrambled and serialized.
The Timed Aux Mezzanine is mounted on the double-wide Timed Aux
Output module.
For the Timed Aux Output Module to function, either the Frame Store or
the Timed Aux Control Module must be installed in cell A17. These
modules have circuitry that latches the VID Data and control data, and
sends it on the backplane to the Timed Aux Output module.
NOTE: The Timed Aux Output module will not work with the Extender Module.

Switcher Module Description
Crosspoint Module (064800)
The Crosspoint Modules distributes all of the video input signals to all the
buses in the system. The Crosspoint Modules work entirely in the serial
digital mode.
After going through the Input Module, the video is sent to both Crosspoint
Modules: M/ E 1, and M/ E 2. Each crosspoint module is an 80 input X 16
output matrix. All inputs are common to both Crosspoint Modules. The
Crosspoint Modules are combined to create an 80 input X 32 output
crosspoint matrix. Only 41 inputs are used
The Crosspoint Modules have a series of 16 input X 8 output crosspoint ICs.
These are put into a circuit to create an 80 input X 16 output crosspoint
matrix. Both of the Crosspoint Modules make use of the HOS processor to
control the aux buses. The two M/ E processors control their respective M/
E and key buses.
The HOS processor is wired to the same connector location in both
Crosspoint Module slots. The M/ E 1 processor is wired to the same
connector location in slot A4 as the M/ E 2 processor is wired to in slot A9.
The function, inputs, outputs, and processor used for each Crosspoint
Module are outlined below:
M/E 1 Crosspoint Module (Slot A4)

Switcher Module Description
Keyer Carrier Module (064804)
The Keyer Carrier Module accepts serial video signals and keys from the
Crosspoint Module and parallel keys and shaped video from the Chroma
Keyer Module for that M/ E. The outputs are shaped video and clipped and
gained keys. Outputs are sent to the Mixer Interface Modules.
The Keyer Carrier Module does the following:
■
■
■
■
■
■
Converts video from serial to parallel (not used with chroma key)
Interfaces to the optional BORDERLINE Mezzanines (key layer only)
Bypasses BORDERLINE mezzanine if not installed
Interfaces to the Key Processor Mezzanines
Can do a non additive mix with the other Keyer Module in that M/ E
Routes wipe and wash information from the Mix/ Wipe Module to the
Key Processor Mezzanine Module
■
■
Generates Box Mask for the Keyer Mezzanine Modules
Transfers key and video fill information from Chroma Keyer Module
to Keyer Mezzanine Module
■
Before being sent off the module, the video signals first have the
chrominance and luminance recombined.
There are two Keyer Carrier Modules for each M/ E for a total of four
modules. Each Keyer Carrier Module has connectors for two Keyer
Mezzanine Modules and one BORDERLINE Mezzanine. There is circuitry
for interfacing to each of these mezzanine modules. The input signals for
each Keyer Carrier Module are the following:
Serial video from the Crosspoint Modules:
■
■
One background video and its key source
One key and its video fill
3-13

Section 3 — Functional Description
The incoming video and keys from the Crosspoint Module are first
converted from serial to parallel. Next, there are selectors that select
between the Chroma Keyer and the Crosspoint Module. The selected video
and key are then sent to the Keyer Mezzanine Modules.
Parallel video from the Keyer Mezzanine Module to the Keyer Carrier
Module are:
■
A clipped, gained and masked key and a shaped video for the
background
■
A clipped, gained and masked key and a shaped video for the key
If there is a BORDERLINE Mezzanine installed, the key goes onto that
module and has a border added to it. The BORDERLINE Mezzanine is
described later in this section.
Next, there is a a Non-Additive Mixer (NAM) in the key path. The NAM
can do a mix between the two keys of that M/ E. The key NAM compares
the luminance level of Key 1 and Key 2 fills and puts the key that has the
highest instantaneous luminance level of its fill on the air. Only the NAM
on the A keyer for each M/ E is active. The video and key from the B keyer
is sent to the A keyer for NAMing.
The outputs of the Keyer Carrier Module are parallel video. The A video
and keys are sent to the Mixer Interface Module, the B video is sent to the
Mixer Module.
Keyer Mezzanine (064826)
There are two Keyer Mezzanines on each of the Key Carrier Module. One
Keyer Mezzanine is for a background layer and the second Keyer
Mezzanine is for the key layer. Backgrounds can be used as keys in the
“Layered Mode.”
On the Keyer Mezzanine Module the video is separated into luminance
and chroma. All videos are timed together and all keys are timed together.
Depending on control panel settings, the video then goes through
processing for gain and offset and coring for noise reduction. Depending
on settings, the key is clipped and gain adjusted, and the video is shaped
by its key. Masks are added, then the signal goes off the keyer Mezzanine
Module and back to the Keyer Carrier Module.

gained key and a shaped video fill
■
Can move the key horizontally in subpixel increments over a six pixel
range
■
■
■
May modify offset and gain on the input video fill
Generates two key fill mattes which can be substituted for the video
Uses signals from the wipe generator to generate a wash between the
two mattes
■
■
■
May mask the key with both force and inhibit masks
Times the inputs
Provides a washed matte border for preset patterns
Input signals for each Keyer Mezzanine Module are:
■
■
Video fill source
Video key source
Each of the Key Mezzanine Modules creates:
■
■
A shaped video fill or washed matte
A clipped, gained and masked key
The Keyer Mezzanine Module has circuitry to time the video and key
signals. The timing is set so that the signals are aligned at the output of the
Keyer Carrier Module even though the keyer path is longer (because of the
BORDERLINE and key NAM) than the background path.
The Keyer Mezzanine Module uses the box mask from the Keyer Carrier
Module, or the wipe masks from the Mix/ Wipe Module, to mask the keys
and key fill. The keys can be filled with matte. The matte is generated by a
dual matte generator on the Key Mezzanine Module. The matte can be
modulated by the wipe signal from the Mix/ Wipe Module.
The functions, inputs, outputs, and processor used for each of the Key
Carrier and Keyer Mezzanine combinations is given below.

When Effects Send is installed, this module acts as a switch. If the switcher
is in normal mode, the Mixer Interface Modules switch the video and keys
from the keyer to the appropriate Mix/ Wipe Module. If the switcher is in
the Effects Send mode, the Mixer Interface Module switches the
appropriate video and key signals from the Keyer Module to the Effects
Send Module which sends the signals to the effects generator on aux bus
outputs. Signals from the effects generator are reentered into the switcher
on aux buses. These signals are routed back to the Effects Send Modules
where they are sent to the Mixer Interface Modules and on to the Mix/
Wipe Modules.

Mix/Wipe Module (064803)
A Mix/ Wipe Module is provided for each of the two M/ Es, (two total). The
Mix/ Wipe Module uses the video signals, key signals and the wipe control
signals to create a video output with all the requested elements. The Mix/
Wipe Module accomplishes the following:
■
Combines video signals, key signals, and the wipe solid signal to create
the program video
■
Interfaces to the Wipe Mezzanine Modules (one standard, one
optional)

The Mix/ Wipe circuit board has connectors for two Wipe Mezzanine
Modules and one Preview Module.
The Mix/ Wipe Module has its own microprocessor, program memory
(flash PROM), and dual port memory. The system processor sends
information to the dual port memory indicating what is to be done during
the next field. The Mix/ Wipe processor reads this information and does the
calculations necessary to accomplish the operations and sends the
information to the rest of the module and the mezzanine modules.
The Mix/ Wipe Module routes the output of each Wipe Mezzanine into the
other Wipe Mezzanine. This allows the mezzanine modules to do a mix or
a NAM (Non Additive Mix) between the outputs of the two mezzanine

Switcher Module Description
Sync Generator Module (064801) (Slot A10)
The basic functions of the Sync Generator Module are:
■
■
■
■
Use the input reference video to lock the switcher
Generate sync pulses for the other modules in the system
Generate clocks for the other modules in the system
Generate “Sync Edge” pulse for analog input alignment
The input is the analog reference video signal. This signal is brought in as
a differential video signal from the Communications I/ O Module at the
rear of the frame. The video is filtered, then sync is stripped off. The sync
is used to lock a 13.5 MHz phase-locked loop. The 13.5 MHz signal is used
to lock a four times 13.5 clock from which all sync pulses are derived.
The two clocks generated on this module are “system clock” and
“multiplex clock” which is twice the frequency of “system clock.” These
clocks have a separate driver for each module. The clock outputs are
differential positive ECL level. The multiplex clock is used on the modules
to multiplex and demultiplex the video signals. The system clock is used to
clock the video through the system.
The system sync pulses are a TTL level and are generated from the four
times 13.5MHz phase lock loop. There are two separate generators, one for
the vertical rate signals and one for the horizontal rate signals. The sync
pulses have drivers that feed four or five modules.
The “dither” mode line is controlled on the Sync Generator Module
through the VID interface.

Overall System Control
Overall System Control
There are three microprocessors in the control panel and either seven or
eight microprocessors in the switcher frame. In the switcher frame there are
two Control Processor Modules (Control Processor 1 and Control
Processor 2).
The multiple microprocessors are designed to prevent total loss of system
control if one of the processors fails. To accomplish this some of the
modules have address and data buses for more than one processor. If one
of the processors fails, the rest of the system continues to function but with
some reduced capability.
The control signals begin in the control panel. The push-buttons and shaft
encoders of the control panel are scanned and any change in the status of
the controls is noted by the appropriate controller and sent to the Control
Processor Modules in the switcher frame.
The Control Processor Modules interpret these signals and send each of the
modules in the switcher frame the correct signal to do the requested
operation. Information programmed in the system (i.e. which input is
assigned to which push-button) is stored on the Control Processor Modules
and is called upon to interpret the information from the control panel.
M/ E 1 control is handled by the M/ E Mezzanine Module (068916) installed
on Control Processor 1 (064805).
M/ E 2 control is accomplished by the M/ E Mezzanine Module (068916)
installed on Control Processor 2 (064806).
DSK control is handled by the Head of State (HOS) Mezzanine Module
(068919) installed on Control Processor 1 (064805).
The HOS processor has overall control of the system.
Strobe: There is a strobe from the processor modules to each of the other
modules to select that module.
Batteries: Each of the processor modules has a lithium battery installed.
They are the power source for the battery backed up RAM when power is
removed from the module.
CAUTION
Be careful not to short out the battery. This can cause permanent damage to the
battery and loss of the data in battery backed up RAM.
Control Processor 1 Module (064805) (Slot A1)
The Control Processor 1 Module has three processors, one on the processor

Introduction
This section provides maintenance and safety information for servicing the
Model 2200 switcher frame, control panel, and switcher power supplies.
Refer to the Diagnostics and Troubleshooting section for procedures to be
used to isolate and resolve specific problems.
NOTE: Torx-head screws are used in the manufacture of many mechanical
components on this equipment. You should have a set of Torx-head screwdrivers
(including sizes T-10 through T-30) available before attempting any mechanical
disassembly and reassembly operations.

Section 4 — Maintenance
Servicing Precautions
CAUTION
To prevent overheating do not operate the switcher frame with the door open for
an extended period of time.
Powering Down
WARNING
Unless specifically directed to do otherwise by a maintenance procedure,
turn power off before removing or repairing any circuit module or assembly
in this system. If the system has redundant power supplies, both supplies
must be turned off.
Before working on any power supply assembly, turn off the power and
disconnect the power cord from the AC power source.
CAUTION
When power to the switcher frame is turned off, the switcher setup at that time will
be lost. E-MEM and configuration data will be retained. To save the setup, save the
setup to E-MEM.
Removing any of the mezzanine modules from the Control Processor Modules will
result in complete data loss from the battery-backed SRAM on that mezzanine
module. This occurs because the batteries supplying power to the mezzanine
module are located on the Control Processor Modules and not on the mezzanines
themselves.
Removing Circuit Modules
All of the video processing and control processing in the system takes place
on circuit modules in the switcher frame and control panel. The locations
of these modules are illustrated in the appropriate portions of this section.
CAUTION
When removing circuit modules from the switcher frame place them on a flat non-
conductive surface. Failure to follow this precaution can result in loss of SRAM data
due to battery discharge or component damage due to electro-static discharge.

Servicing Precautions
Two optional circuit module extenders are available. One is for use with
the main video processing and control modules located in the front bay of
the switcher. The second is for use with the I/ O and communications
modules in the rear bay. The extender modules allow operation of the
system while providing access to test points and adjustments that would
be inaccessible with the module seated normally.
CAUTION
If a circuit module in the switcher frame is removed or reinstalled while the power
is on, it is unlikely that permanent damage will occur to the module or system.
Microprocessor messages, however, may become scrambled. This may result in
system errors and improper operation. If these problems occur, the only sure way
to restore proper operation is to turn the frame power OFF, wait a few seconds,
then turn power back ON again. The power-up sequence will re-synchronize the
microprocessors.
Repairing Circuit Modules
Model 2200 circuit modules are not designed to be repaired in the field.
Failed modules should be replaced.
Surface mount technology and multi-layer printed circuit manufacturing
techniques have been used in many of the circuit modules. Specialized
equipment and training are required to properly repair these modules.
CAUTION
Do not attempt component-level field repair on these circuit modules. Use of
improper tools or equipment to repair multi-layer circuit modules could result in
expensive damage to your system.
Repairing Power Supplies
GVG does not recommend or support field repair of Model 2200 power
supplies. Failed power supplies should be replaced.

Section 4 — Maintenance
WARNING
Remove all rings and other jewelry when you are working on equipment that
is powered up. Hazardous currents are present in the power supplies, on the
backplane, and on circuit modules. Failure to follow this precaution could
result in severe shock and other injury.
Only qualified service personnel should work on the control panel and
switcher power supply assemblies. Failure to observe this precaution could
result in severe shock or expensive damage to your equipment.
Model 2200 Power Supply Configurations
The standard power supply configuration for the Model 2200 is a single
supply chassis for the Signal Processor Frame and single supply for the
Control Panel. These power supplies are separately connected to AC
source power.
The Control Panel and Signal Processing Frame can each, optionally, be
configured with a second (redundant) power supply.
The redundant supply for the Signal Processing Frame is identical to the
standard supply. It is installed, in the rack below, and in tandem with the
first. They are configured to share the current load, and the failure of a
single supply should not cause a switcher failure.
When the Control Panel is configured with redundant power supplies,
both supplies are installed inside the main control panel tub.
Frame Power Supply Assemblies
Each Signal Processor Power Supply assembly for a Model 2200 Switcher
consists of a rack-mounted frame (assembly number 098901-XX)
containing a Multi-Output Power Supply unit and a high-current +5 Volt
Power Supply unit. The assembly number of the power supply frame is
noted on the back of the frame. Grass Valley assembles and tests the power
supplies; however, the individual power units in the power supplies are
manufactured by other suppliers.
There are two suppliers of the individual power supply units—Pioneer
Magnetics and Todd Products Corporation. Differences between the units
and important notes about them will be presented here for ease of
installation.

Servicing Precautions
It is important to know what type of power units you have for the reasons
listed below:
1. Because of differences in the electronic design, it is not possible to
operate Pioneer and Todd power units of the same type in a redundant
power supply configuration. In other words, you may not connect a
Pioneer Multi-Output unit in parallel with a Todd Multi-Output unit,
and you may not connect a Pioneer +5 Volt unit in parallel with a Todd
+5 Volt unit.
2. A Model 2200 switcher with Todd power supply units may operate on
110VAC. Pioneer supply units must always operate on 220VAC.
3. Todd +5V power supply units are internally wired for power surge
protection, Pioneer +5V power supply units are not. There is a jumper
in the Model 2200 fan assembly at the top of the Signal Processor Frame
which must be set to either bypass or enable a surge protection circuit
depending on the type of unit present. Refer to the “Fan Jumper
Settings” heading in Section 2 in this manual.
Before replacing your power supply, you will need to determine the type
of supply units you have. To do this:
1. Locate the assembly number sticker on the back of the power supply
frame. Systems with Pioneer power units will have power supply
frames numbered 098901-00 or -01. Systems with Todd power units
will have frames labeled 098901-03.
2. Remove the back covers on the left and right sides of the primary and/
or redundant power supply frames. Leave the covers off for installation
purposes later.
You may distinguish between a Todd supply and a Pioneer supply as
follows:
Viewed from the front, both +5 V and Multi-Output Pioneer units are
each about 5 inches wide, and each has a 4 1/ 2 inch diameter fan.
The Todd +5 V unit (on the left) is about 3 1/ 2 inches wide. The Multi-
Output supply is slightly narrower. Each supply has two cooling fans.
From the rear, the Todd and Pioneer +5 Volt units can also be identified
by the positions of the large power lugs on the rear of the supplies.
They are arranged horizontally on the Pioneer supplies, and diagonally
on the Todd supplies. For clarity however, both types of supplies will
be illustrated in this manual in most cases.

6. Place a wheeled cart or some appropriate support in the front of the
power supply chassis to support it as it is removed.
7. Release the chassis from the rack by removing the screws at the front of
the chassis at the left and right hand lip. See Figure 4-1.
WARNING
If the equipment rack is not securely bolted down to the floor, do not extend
it on its mounting rails.The weight of the power supply chassis, when
extended on the mounting rails, is enough to topple the equipment rack if it
is not bolted down or otherwise supported. Failure to follow this precaution
could result in injury or damage to the equipment.
8. While guiding the heavy cables at the right rear through the cut-out in
the chassis, pull the chassis out on its mounting rails until they are fully
extended.
9. Release the chassis from the rails by locating and pressing the two
release buttons (one on each rail).
10. Using two persons or an appropriate lifting device, remove the chassis

Servicing Precautions
Replacement of Individual Power Supply Assemblies
If it is necessary to replace an individual power supply in the Signal
Processor Frame Power Supply, it is important for you to be aware of the
following information:
■
Two types of power supplies are used in the Signal Processor Frame
Power Supply for the 2200 Switchers—a Multi-Output supply and a
high-current +5 Volt supply.
■
Power supply units from two different manufacturers—Pioneer
Magnetics and Todd Products Corporation—have been used in the
Signal Processor Frame Power Supplies.
The units from the two manufacturers are very different in appearance, but
are electrically compatible, with the following exception:
In a redundant power system, the two +5 Volt supplies must be of the
same “make” and the two Multi-Output supplies must be of the same
make. (The +5 Volt and Multi-Output supplies, however, may be of
different makes.)
This means that if you need to replace one power supply assembly in a
redundant power system, you must either replace that supply with one
of the same make, or replace both supplies that operate in parallel.
Check to see that your replacement is compatible in a redundant system,
and, if necessary, contact Grass Valley Customer Service.
NOTE: In a non-redundant power system, if both power supply units (one Multi-
Output and one +5V) in the single power supply frame are Todd supplies, the
frame can be wired to operate on 110 volts, as described in the Installation Section
of this manual.
Configurations
Each power supply comes as a complete assembly (“sled”) that must be
replaced as a unit. As viewed from the rear of the frame, the +5 Volt supply
assembly is located in the compartment at the right side of the chassis and
the Multi-Output (+13V/ –13V/ –5.2V/ +48V) supply is located in the
compartment at the left.

Section 4 — Maintenance
Procedures
The following procedures (one for the Multi-Output supply and one for the
+5 Volt supply) describe replacing Pioneer power supply assemblies with
Todd power supply assemblies.
For any of the other three possible replacements—replacing a Pioneer unit
with a Pioneer, replacing a Todd unit with a Todd, or replacing a Todd unit
with a Pioneer—use the following procedures as guides and perform the
appropriate steps.
Replacement of Multi-Output Power Supply Assembly
NOTE: In order to replace a Pioneer Multi-Output supply with a Todd Multi-
Output supply, you will need to have the installation kit that is part of Field
Modification Note FM2025.
To replace a Pioneer Multi-Output assembly with a Todd Multi-Output
assembly, proceed as follows:
1. On the front panel of the main Signal Processor Frame Power Supply,
turn off the main power switch. The indicator LEDs on the front panel
will go out.
If there is a Redundant Signal Processor Frame Power Supply, also turn
off its main power switch.
2. Inside the switcher Control Panel, turn off the main Control Panel
Power Supply switch and (if present) the redundant Control Panel
Power Supply switch.
3. At the rear of the equipment rack, disconnect AC power from the Signal
Processor Frame Power Supply by unplugging the cable from the AC
power source.
If there is a redundant Signal Processor Frame Power Supply, also
disconnect it from the AC power source.
WARNING
If a redundant power supply is installed, power to both supplies must be
disconnected, due to the interconnecting wiring.

Switcher Frame Module Precautions
Switcher Frame Module Precautions
The locations of the switcher frame bays and circuit modules are illustrated
are slide-in units that are easily removed and replaced.
The existing setup of the switcher is lost when power to a switcher frame is
turned off. E-MEM and switcher configuration are not lost because they are
stored in non-volatile RAM. If you wish to save the switcher setup, save the
setup to an E-MEM. It is recommended that power to the frame be turned
off whenever any modules are to be removed or reinstalled.
If a Signal Processor module is removed or installed while the power is on,
no damage occurs to the module or to the system, but microprocessor
messages may get scrambled, resulting in operational problems. If this
happens, the only sure way to restore proper operation is to turn the
switcher frame off, wait a few seconds, and turn it back on again. The
power-up sequence will synchronize the microprocessors.
It is recommended that the power to the switcher frame be turned off
whenever modules are removed or replaced.
WARNING
High current capability is present in the switcher frame. Remove all rings and
other jewelry when working switcher frame, and use caution when using
metal tools in the vicinity of power buses.
CAUTION
Many of the circuit modules in the switcher frame are sensitive to static discharge.
Failure to use proper static-control procedures while working on circuit modules
may cause data loss and/or destruction of static-sensitive devices.

Section 4 — Maintenance
Draining the Control Processor RAM
If, after installing a software update, your floppy disk drive does not
respond, you need to drain the Control Processor RAM on the two Control
Processor modules. Follow the procedure listed below:
1. Remove the Control Processor I module located in the Switcher
Processor Frame Slot A1 in the Model 2200 frame.
2. Remove the jumper located near the Lithium battery.
3. Wait 15 minutes for the dielectric-capacitors to discharge. Or, to
expedite the discharge process, connect the left jumper-pin to the
nearest ground. This action drains the capacitor’s charge immediately.
4. Replace the Control Processor module into the Processor Frame.
5. Then remove the Control Processor II module located in slot A2 in the
Switcher Processor Frame.
6. Remove the jumper across J9. Jumper J9 is located near the Lithium
battery.
7. Wait 15 minutes for the dielectric-capacitors to discharge. Or, to
expedite the discharge process, connect the right jumper-pin to the
nearest ground. This action drains the capacitor’s charge immediately.
8. Replace the Control Processor II module into the Processor Frame.
9. Replace the Control Processor module(s) and return power to the
frame.
