SECTION 1.0: INTRODUCTION  
1.1 HS DEFINED  
The CM9760-HS (Hot Switch) provides single-node, switching control between two CM9700-CC1  
matrix switches. The default HS package consists of three subunits*, interconnected via in out, DB37,  
male-to-male, molded cables that form a common bus for the subunits. These units provide the  
interfaced system with operational redundancy.  
Failure of the controlling matrix switch (designated the Master) passes control to the backup (designated  
the Slave). Conversely, if the Slave unit fails, control remains with the Master unit. Any system failure  
generates a system error that lights the FAULT LED (visual), and turns on an accompanying audible tone.  
The audible signal is automatic unless turned off by DIP switch 1-1 (see Figure 2-4, DIP Switch  
Configuration). Figure 1-1 depicts the basic physical relationship between the HS, the interfaced CC1s,  
and the external devices connected to the CPS and SEU output ports.  
* The Serial Expansion Unit (SEU) is one of these units. However, it varies in number from one  
(default), up to a possible eight units, depending on system configuration. Additional SEU units are  
physically added to the hot switch via the HS common bus. Two SEU units are needed to interface a  
fully populated CC1 (four Sercom cards containing a total of 32 ports). Future development may  
require more than 32 Sercom ports to be interfaced. When that happens, SEU units (up to eight  
total) can be added to the common bus to accommodate the increase in Sercom port population.

Figure 1-1. HS Block Diagram  
Diagnostic equipment connected to CPS output ports display the status of HS health. Other devices,  
connected to SEU output ports are under CC1 A or CC1 B control. For this reason, the interfaced  
matrix switches must be hardware-software clones of each other in order for either to control the  
same set of devices and to ensure a smooth transfer if a control transition (changeover) occurs.  
Matrix switch equality is assured in the following manner:  
Both switches must physically interface the HS in the same way. All cables and connections on  
the A-side, switch-to-HS interface, are duplicated on the B-side. Basic interface requirements are  
discussed in installation subsection 2.1 Physical. Additional installation issues, beyond basic  
setup, are discussed in Section 4.0 Appendices.  
The physical equivalence of the matrix switches is likewise mirrored in their respective software  
configuration file sets (Comms, Monitor, Camera, etc.) that are used to initialize and operate  
each switch. Both sets must be identical.  
Refer to the CM9700-MGR Getting Started Software Guide, on-screen help, or Online Help for  
information about programming configuration files.

1.2 CC1 CONNECTION GROUPS  
The rear view of a matrix switch (referenced in the block diagram of Figure 1-1) is shown in  
Figure 1-2. Outputs destined for HS connections can be categorized, corresponding to the designated  
functions of the subunits to which they are attached on the hot switch. For discussion purposes, these  
outputs are partitioned into three groups: the Control group, the Diagnostic-Peripheral group and the  
External Expansion group.

1.3 HS HARDWARE THUMBNAIL  
Figure 1-3 expands the HS portion of Figure 1-1 to illustrate an uncluttered, thumbnail rear view of the  
hot switch subunits that comprise a default HS configuration. Connection cable destinations from each  
CC1 (matrix switch), referenced in the previous figure, are attached to the appropriate side (CC1 ‘A’ or  
CC1 ‘B’) of the hot switch subunits. The subunit acronyms have the following meanings: the CCC  
(Computer Changeover Control), the CPS (Computer Peripheral Switch) and the SEU (Serial  
Expansion Unit).  
Note that the CCC front panel is included in this illustration. Operation buttons for the user are located  
there. Also shown is the 37-pin, D-type, molded cable, used to create common bus connectivity  
between the subunits. (Except for the CPS, one DB37 cable is supplied with each subunit). Front  
panels for the CPS and SEU are similar to that shown for the CCC (minus the operation buttons), with  
labeling appropriate to each unit.

The CCC subunit is the heart of the hot switch. Data connections between the interfaced CC1s  
(matrix switches) and the HS are located here. Two connector types that correspond to two  
NOTE: When upgrading to  
the current hot switch from a  
previous model, note the  
following. The data cable,  
previously used to connect  
RJ-45 port 5 on each switch  
and the corresponding COM 1  
[S1] and COM 2 [S2] ports on  
the hot switch, cannot be  
substituted here.  
communication types for the data line to the CCC are provided: RJ-45 or DB9.You can use either, but  
the connector type chosen determines the communication protocol you must use and vice versa.  
Both are illustrated in Figure 1-5. In the top portion of Figure 1-5, the RJ-45 data line connection (one  
from each switch) is shown. If RS-422 communication is chosen, the data cable from a port on matrix  
switch CC1 ‘A’ (an RJ-45 Sercom port, usually port 5) is run to the RJ-45 CC1 A port on the CCC. A  
similar cable is run from CC1 ‘B’ to the RJ-45 CC1 B port on the same CCC. These cables are re-  
versed or “flipped” and utilize pins 1, 2, 7, and 8 as depicted in Figure 1-4. Alternately, in the bottom  
portion of Figure 1-11, the RS-232 data line connection is shown. A DB9 cable is run from either the  
COM 1 or COM 2 port (on the respective CC1 ‘A’ or CC1 ‘B’ switch) to the appropriate (CC1 A or B)  
DB9 port on the CCC. The cables for the DB9 data connection runs are not supplied. Pelco  
recommends that RS-422 communication be used whenever possible. The cables for the RS-422  
data connections are provided.

In addition to communications, there are number of additional functions handled by the CM9760-CCC.  
POWER  
The power-input connector, fuse, and ON/OFF switch are located here. Input  
power for the entire HS originates here. Power is distributed to the CPS and SEU  
subunits via DB37 common bus connections.  
LOGGING  
PRINTER PORT This is used, if desired, as an output logging device for system or status reports  
related to hot switch operation only. The port supports dot matrix printers capable  
of IBM or Epson emulation modes, such as the Okidata 320 (non-turbo) and the  
Okidata 390 (turbo) or 391 (turbo).  
LEDs  
The FAULT, A, and B LEDs are located on the front panel of the unit. These give  
visual indications of system status with respect to control, mode of operation, and  
system failure. See the LEDs section of 3.3 Operator Tools.  
FRONT PANEL  
BUTTONS  
The front panel buttons are utilized by the operator for responding to system  
errors, for checking system status, and for operational control when changes are  
made to system hardware and/or software. See the Front Panel Buttons section  
of 3.3 Operator Tools.

The connectors on the rear of the CPS are divided into three duplicate sections. Each section contains  
an AT KBD connector,  
a VGA connector,  
a PRINTER connector,  
a COM 1 connector (port), and  
a COM 2 connector (port).  
Each duplicate section is labeled. From left to right, they are the CC1 ‘A’ section, the CC1 ‘B’ section,  
and the EQUIPMENT section. The first two (CC1 ‘A’ and CC1 ‘B’) are connection input destinations  
for the corresponding switch it interfaces—one from the A-side, and one from the B-side switch. The  
third section (EQUIPMENT) provides the connectors to which the following standard diagnostic  
devices can be attached:  
1. An AT keyboard (to the AT KBD connector)  
2. A VGA monitor (to the VGA connector)  
3. A system printer (to the PRINTER connector)  
4. A PC W/Pelco MGR software (to the COM 1 port)  
As a user, you are always connected (through either one matrix switch or the other) to the diagnostic  
tools that are attached to the EQUIPMENT output ports. The switch through which you operate (the  
one in control and designated the Master) is normally granted automatic access to those devices  
(default). If control is switched, the backup switch (Slave) becomes the designated Master, roles are  
reversed, and the output diagnostic connections change to follow suit. This happens automatically if  
DIP switch 1-2 is ON and DIP 1-6 is OFF (default). See Figure 2-4, DIP Switch Configuration.  
Note that only four diagnostic devices are listed for the five available output ports. Two of the five  
output ports deserve further comment.  
COM 1 is reserved for the connection of the PC with MGR software (see Figure 1-11).  
COM 2 can be used in two ways:  
1. As a “user” defined configuration for the connection of devices and/or electronic equipment to  
the COM 2 A and B inputs and to the COM 2 EQUIPMENT output port. The COM 2 ports are  
D-type, 25-pin connectors, and can be used for the connection of user-optioned equipment.  
Applied voltages to COM 2 connector pins should not exceed 25 VDC. For this use, the  
operation of the COM 2 port is not necessary for the successful operation of any function of the  
HS. Insert A of Figure 1-6 is a diagrammatic drawing of the wiring of the COM 2 connectors.  
2. For the connection (to the EQUIPMENT section’s COM 2 output port) of an RS-232, DT (Data  
Translator). As part of the CPS package, three DB25 (female) to DB9 (male) adapters are pro-  
vided for this purpose (along with the associated cabling for the A- and B-side inputs to these  
adapters).

This allows users with existing RS-232 DT devices to retain that configuration capability in the new  
HS. Figure 1-6 highlights the geometry of this hookup.  
Additional DTs of the same type must be connected to CC1 Sercom ports (via SEU output ports of the  
HS) and require RS-232 to -422 converters.  
20078  
Figure 1-6. COM 2 Port Options  
A couple of working rules with respect to diagnostic tool availability are in order here. During default  
operation (see Figures 2-4 and Figure 2-5) diagnostic tools attached to EQUIPMENT output ports  
“follow” the switch in control. Under these conditions, the following results can be expected when the  
described operation is performed:  
1. You can view, at will, the diagnostic activity for either switch (Master or Slave) regardless of the  
operational mode (including default) as long as that switch is online. This is done by pressing the  
KVD (Keyboard, Video, Data) A (or B) button located on the front panel of the CM9760-CCC for  
the A- or B-side diagnostic view you want to see (see Table B, Front Panel Button Operation).  
When the KVD button is pressed, you will view the devices connected to the AT KBD, and VGA  
port connections for the side (A or B), (Master or Slave) that you selected. It is important to note  
that the PRINTER, COM 1, and COM 2 ports do not follow KVD activity under any circumstances.  
2. If the diagnostic view is switched manually via the KVD button, as in (1), it remains there until  
(a) the operator manually switches back to the opposite side, or until  
(b) the system forces a change due to a system fault. A system fault may or may not result in a  
return to the original diagnostic view. That depends on which switch becomes the desig-  
nated Master when the changeover, if deemed necessary, occurs. This is determined by  
the HS itself. It occurs automatically as the result of configuration settings and is not under  
user control.  
3. Any system change (as noted in 2b) co-opts any existing diagnostic view and any resulting  
change occurs under the control of the HS and not the operator. Moreover, the HS controls and  
automatically transfers ALL ports (including COM 1 and COM 2) to the control of the designated  
Master in the event of a system failure.

The SEU subunit of the HS, like that of the CPS, is also divided into three sections. Devices  
connected to the SEU EQUIPMENT output ports are under the control of only one CC1 at a time. The  
controlling switch is designated the Master, regardless of mode (synchronous or asynchronous).  
Unlike the CPS, however, there are no predefined port designations for SEU Sercom input ports that  
physically correspond to the port designations as they are defined by physical location on any  
9760-CC1 matrix switch. On the matrix switch, port 5 is port 5 and is always located at the “port 5”  
position, and so on.  
The physical relationship between matrix switch Sercom outputs and the A/B inputs on the SEU are  
defined by the following statements:  
1. The function of each Sercom input port on the SEU (CC1 ‘A’ or CC1 ‘B’) is characterized by  
whatever is plugged into it.  
2. A specific physical relationship (depicted in Figure 1-7) exists internally between SEU Sercom  
inputs (A or B) and associated SEU EQUIPMENT outputs.  
The Sercom ports on the SEU shown in Figure 1-7 are isolated and numbered (for explanatory purposes);  
the ports on the SEU are physically related as illustrated.

The physical relationship depicted above is repeated for all corresponding physical port locations;  
that is, A2 is related to B2 and the output E2 in the same way that A1 is related to B1, and the E1  
output.  
This relationship holds true for the remaining port locations: A3-A16, B3-B16, and E3-E16.  
In line with the port relationship just discussed, you must also maintain corresponding equipment  
integrity with respect to the input port locations chosen for attaching A- and B-side input cables. This  
is so that output control, from either matrix switch, of a device connected to a specific SEU output  
port, corresponds, in fact, to the same physical device.  
For example: If a matrix bay is hardware-software configured for attachment to port 7 on 9700-CC1 A,  
then it also must be configured the same for port 7 on 9700-CC1 B, since the CC1s must be hardware-  
software clones of each other. If you then run a cable from 9700-CC1 A, port 7, to the CC1 ‘A’ side of the  
SEU and attach it to the A1 port, then you must also run a corresponding cable from 9700-CC1 B, port 7,  
to the CC1 ‘B’ side of the SEU and attach it to port B1.The matrix bay itself, is connected to the corre-  
sponding output port, E1, on the SEU.  
As indicated above, the configured outputs of 9700-CC1 ports can be plugged into any input port on  
the appropriate SEU, as long as you allow for the physical constraint illustrated in Figure 1-7, above.

A NOTE OF CAUTION: Random attachment of cabling between CC1s and SEUs can lead to confu-  
sion about what is attached where. It is suggested that you map the physical port arrangement found in  
your CC1 outputs to those utilized on the SEU (as far as that is possible). One method is to mentally  
rotate the SEU (clockwise or counterclockwise, it does not matter) and associate the port locations you  
use on the SEU to those existing on the CC1. In Figure 1-8 , the CC1 ‘A’ side of the SEU is shown  
rotated counterclockwise.You can extend the use of this visual mnemonic to the SEU’s B side, the  
output, and additional SEUs, if needed (also see the NOTE in Figure 1-8).

MASTER/SLAVE STATUS FOR CC1  
Sercom port 1 on the CC1-A or CC1-B side of the SEU subunit may be wired to provide the current  
status of the CM9760-HS. This wiring connection will allow for monitoring that alerts the user to  
primary (master) CPU (CC1) failure. When the secondary (slave) CPU assumes primary control, the  
user can be alerted remotely via the closure of an external alarm. This connection is made by  
constructing an RJ-45 terminated wire (not provided) and shorting pins 1 and 2 (CC1-A) or pins 7 and  
8 (CC1-B) together on the CC1 side only. The CC1 port (A or B) is connected to the EQUIPMENT  
side port 1. See Figures 1-9 and 1-10.

1.5 INSTALLATION PREVIEW  
Figure 1-11 combines elements of previous illustrations into what is essentially a wire routing of the  
block diagram of Figure 1-1. This is an overview of the physical geometry of an HS integrated into a  
basic, default system configuration. Section 2.1 Physical in Section 2.0 Installation, breaks up Figure  
1-11 into its logical component groupings, where cabling requirements for each section are isolated  
and examined in detail. Cabling in the current model hot switch is rather straightforward.  
Other Remarks:  
In addition to basic hookup, which covers the information needed for a new, single-node installation,  
the following configuration processes are discussed in Section 4.0 Appendices.  
HS addition to an existing configuration, (no hot switch currently installed)  
HS update, (previous model of hot switch installed)  
HS update (current model hot switch installed)  
HS and networked configurations  
Installation Checklist:  
The basic install process for integrating a hot switch within a single system node can be broken down  
into the following steps:  
1. Mount the components of the hot switch (standard rack-mount) in such a way as to take  
advantage of the equipment that will attach to each unit. At the same time, be mindful of the rela-  
tively short interconnect cables that form the common bus between the subunits of the HS.  
Install the interconnect cables that form the common bus (see Figure 1-3 for a picture of this  
cabling). Install the power cord on the CM9760-CCC, but do not apply power to the unit.  
2. Connect all remaining cabling that is required for your system node. Follow, in order, all items of  
2.1 Physical in Section 2.0 Installation of the manual, for instructions. Configure DIP switch one  
and two located behind the front panel of the CM9760-CCC subunit (see Figure 2-4).  
3. Install all required software. Ensure that duplicate sets of configuration files for the  
interfaced matrix switches are installed on the respective hard drives of each switch.  
Check to make sure that port references to attached equipment match the equipment  
actually attached to those ports. Refer to the appropriate sections of the latest version of  
the MGR programming for general information on filling out configuration files. Refer to  
the appropriate sections of the latest revision of the matrix switch manual (C541M), for  
information on installing configuration files and other items related to file manipulation.  
Be sure to add the hot switch to the COMMS configuration file, if not already done.  
4. After all cabling and software is installed, apply power to the HS and all attached equipment and  
let the systems initialize (see 2.2 Power-up and Initialization in Section 2.0 Installation).

The connection points for diagnostic and monitor tools for hot switch and system status are shown in  
Figure 2-2. Note that COM 1 on either CC1 (the normal connection point for the PC w/MGR in a  
stand-alone CC1 configuration) is run to the appropriate COM 1 input connector on the CPS. COM 1  
output on the CPS is reserved for the PC w/MGR connection. If a CC1 COM port on the switch is  
defective, the other port can be used, but you must still connect to COM 1 on the CPS. Moreover, you  
must follow suit on any change in physical COM port configuration in the duplicate CC1. In addition, any  
port changes must be reflected in the COMMS file.

2.2 POWER-UP AND INITIALIZATION  
Once configuration files have been programmed and loaded and all connection cabling has been run,  
then the associated CC1s, the hot switch and all connected devices can be turned on.  
The order of equipment turn-on is immaterial; however, if the HS is turned on before either CC1  
finishes initialization, the online LEDs (A and B) on the front panel of the CCC will alternate rapidly  
back and forth. In addition, if the HS is ON and one CC1 finishes initialization ahead of the other, you  
might notice that it will temporarily be made the Master and the mode will be Asynchronous. This is  
no cause for concern; it is normal. When the entire system finally initializes, the CCC determines  
whether default operating conditions are possible, and, if they are, the system will enter synchronous,  
A-Side (Master) control, with B-Side (Slave). A visual check of successful initialization appears on  
appropriately connected diagnostic monitors; however, the primary indicator of successful initialization  
is a visual check of the LEDs located on the front panel of the CCC. Figure 2-5 illustrates this.

SECTION 3.0: OPERATION  
3.1 PRELIMINARY REMARKS  
There are two modes of HS operation. One is termed the synchronous mode and the other, the asyn-  
chronous mode. Synchronous mode, of course, is the desired mode of operation. It is the optimal  
mode of operation and the one the HS is designed to operate under. It is also the default mode of  
operation and the only mode that provides proper backup to the system. The asynchronous mode,  
on the other hand, is the mode the system reverts to (from synchronous mode) when a system error  
occurs, for whatever reason. It is important to point out, however, that even in asynchronous mode,  
the system is still up. In that sense, the asynchronous mode is also a successful mode because it  
means that the HS successfully passed control to the working CC1 and that the interfaced system is  
still operational. Once faults are corrected, the operator can manually return the system to its de-  
signed optimal, default configuration. This process, among others, is discussed in detail in Table E.  
3.2 TERMS AND DEFINITIONS  
The following terms are used extensively in the next few sections. We list a working definition of each  
term to reduce confusion about their meaning when used in conjunction with the hot switch.  
Synchronous – A hot switch operational mode that is the primary, default mode of HS operation. It  
normally occurs at the end of a successful start-up. Once enabled, synchronous-mode control can be  
switched from one matrix switch to the other by pressing the appropriate CC1 A or CC1 B button once.  
Asynchronous – A hot switch operational mode in which the side in control is not synchronized with  
the other side. It occurs as a result of any of the following:  
1. A CC1-generated failure report to the HS. The HS FAULT LED is lit.  
2. Manual intervention by an operator via front panel switches (pressing and holding CC1 A or  
CC1 B button for two beeps). The HS FAULT LED is not lit.  
3. A CC1 failure detected by the HS that one of the two CC1s is not operational. FAULT LED is lit.  
When asynchronous mode is entered, the following may occur (dependent on the state of the system  
at the time the action occurs):  
1. A snapshot of the current state of the primary CC1 (if it has failed) is made and passed on to the  
backup CC1.  
2. The auto-changeover sequence is initiated and control is passed to the backup CC1, which is  
automatically put into asynchronous mode.  
3. If the backup fails, control remains with the primary Master unit. It is automatically put into asyn-  
chronous mode.  
Synchronization – An ongoing dynamic process wherein the current camera-monitor-user status  
of the primary (Master or control side) is continually updated to the secondary (Slave or back-up)  
side. The internal dynamics of the process is not under user control.  
Changeover – A word that describes the automatic process of passing from synchronous to asyn-  
chronous or from asynchronous to asynchronous mode because of the failure of either CC1 (primary  
or backup), while in synchronous or asynchronous mode, respectively. Of course, the appropriate DIP  
switch settings must be configured to allow this.  
The HS implements an automatic changeover for the following reasons:  
1. There is a primary COM failure with either CC1.  
2. A secondary problem with either CC1 that results in its failure.  
Either of the above results in the system FAULT LED being lit.  
Additionally, changeovers can be manually initiated by the operator (see Table B). The FAULT  
LED is not lit.

3.3 OPERATOR TOOLS  
LEDs  
A visual check of LED activity should be the top item on your checklist for determining the operational  
status of the HS and the attached system. LED status tells you the following:  
Which mode (synchronous or asynchronous) the HS Is operating in  
Which side (A or B) is in control (synchronous mode)  
Which side (A or B) is in control (asynchronous mode)  
Which side is in control after an equipment failure  
Which side caused the system FAULT

An operational system is always in synchronous or asynchronous mode; otherwise, the system is  
down. There are no intermediate operational states.  
Table A relates LED activity to the function listed in the left-hand column for the given operational modes.

FRONT PANEL BUTTONS  
Front panel buttons (CC1 [A or B]) are used to respond to HS detected system errors and for direct  
implementation of other HS functions when needed or required, such as troubleshooting or update  
procedures.  
When used in conjunction with LED readouts and other diagnostic tools, an operator can pinpoint  
current system status and/or implement appropriate corrective action, as needed. Using the front  
panel buttons, an operator can  
1. Acknowledge a system FAULT (turn it off)  
2. Change from asynchronous to synchronous mode or its converse  
3. Switch primary system control from one CC1 to the other  
4. Switch diagnostic view from the A- to the B-side and vice versa

3.4 OPERATOR RESPONSES AND METHODS  
User interaction with the HS is necessary when (1) a system error occurs, which generates a FAULT  
LED, and (2) when a software/hardware change or upgrade to the system must be made. System  
FAULTS are discussed first.  
SYSTEM FAULTS  
Although error response is addressed in the previous table, not all FAULT situations are covered  
there.  
Any alarm results in the FAULT LED being lit. An associated audible notification also occurs if optioned  
via DIP switch.You can turn off audible notification (default) by setting DIP switch 1-1 to the OFF  
position (see Figure 2-4). Note that this does not affect the audible two-beep tone associated with  
manually asserting asynchronous mode.  
In any FAULT situation, system control is passed to or remains with the “working” CC1, which then  
automatically reverts to or remains in asynchronous mode. The following table summarizes system  
operation and the necessary user response to any FAULT variation, given the stated initial conditions:

* In this instance, the side in question is in asynchronous mode as the result of operator action, not because the opposite side had  
previously failed.  
** If you are in A or B, asynchronous mode because the opposite side previously failed and now the side in question fails before the  
opposite side is repaired and brought back up, then the entire system is down.  
*** The “RESULT” mode indicated here will not appear on the diagnostic monitor until the FAULT LED is acknowledged.  
The above cases of FAULT activity can be summarized in the following statements:  
If both interfaced matrix switches (CC1s) are working, any system error leaves one of the two  
CC1s in control.  
Any error always puts the system in asynchronous mode, if it is not there already.  
In each case, to turn OFF or ACK the FAULT, you must manually reassert asynchronous mode  
for the side in control after the error occurs (the LED light for the side in control [A or B] is ON  
solid). Hold the CC1 A or CC1 B front panel button until the audible two-beep tone is heard.

DIAGNOSTIC MONITOR AND SYSTEM WINDOW USE  
Normal Operation  
During normal startup, the diagnostic screen on the monitor (attached to the VGA output of the CPS-  
see Figure 1-11) reflects successful hot switch initialization. Likewise, the system window of the PC  
with MGR that is attached to the COM 1 output port of the CPS reflects the online status of the sys-  
tem node (see Figure 3-1 below), but gives no additional information. In fact, the system window indi-  
cates nothing amiss even if only one of the two available CC1s boots, and comes online successfully.  
Although the system window reflects the status of the CC1 currently in control, it is not the tool of  
choice for information regarding hot switch operation. To the MGR, hot switch operation is essentially  
transparent.  
20071  
Figure 3-1. System Window Online Status  
On the other hand, diagnostic screen displays, in addition to those associated with initialization, are  
useful (see Figure 2-5). Diagnostic screen information, combined with LED activity, are the primary  
sources of information on the status of hot-switch interfaced systems. Operationally, the diagnostic  
screen supplies the following information:  
1. It reflects the status of the controlling CC1 (if DIP switch 1-2 is ON**)  
2. If DIP switch 1-2 is OFF, it reflects the status of the last selected CC1 (normally operator-selected  
via the KVD button).  
** This does not prevent the operator, if he wants, from viewing the diagnostic screen of the  
non-controlling CC1. If the diagnostic view is changed by the operator to the non-controlling  
CC1, that view will remain on-screen until an event occurs that updates system parameters  
or until the operator changes the view back to the original, controlling CC1. The default DIP  
switch setting is meant to automatically switch the diagnostic monitor to view the currently  
active CC1 in the event a changeover occurs. A changeover is an HS-controlled event that  
occurs because one of the CC1s is no longer operational. The result is an HS system error  
that is accompanied by an audible alarm tone and a visual LED FAULT light.  
The most important area of the diagnostic screen to watch is located in the lower right-hand portion of  
the display. There, you can read off the current mode of operation, which CC1 is in control, and the  
software version of the system executable. These items are highlighted in Table D.  
Diagnostic screen displays change as the result of direct operator action or because of automatic HS  
response to system failure. Table D addresses those changes. Table D is similar to Table B, except  
that in Table D, diagnostic screen display information, rather than LED activity, is related to the  
implementation of the function listed in the left-hand column. The starting point is the diagnostic  
display for default initialization. The diagnostic screens for both the A- and B-side matrix switches are  
shown. The screen seen during normal default operation is the one associated with the controlling  
switch (unless you opt to view the non-controlling diagnostic by pressing the appropriate KVD button).  
That is why both diagnostic screens are illustrated.

SYSTEM UPDATE PROCEDURE  
Table E (see NOTE at end of Table) describes the procedure to follow when it is necessary to update,  
change, or add any hardware/software item associated with a hot-switched, online system node. The  
procedure, explicitly detailed in Table E, proceeds through the following steps:  
1. Manually puts A- or B-side into asynchronous mode (Table E starts with A-side), and takes the  
opposite side offline.  
2. Repairs or updates to components of the offline system are made.  
3. Power is applied to the offline unit, it is then synchronized, after which asynchronous mode is  
asserted on the same side.  
4. The opposite side is taken offline where the same updates and changes are made, the unit is  
powered up, and then the system is resynchronized.

position so that diagnostic control reverts to the user, then, in Step 4, take the side that generated the error offline (if not already  
done). Next, acknowledge the alarm (to turn it off) and then,follow steps 5 and 6 of Table E, substituting the appropriate-side button  
presses (it depends on which side was initially taken offline), and then skip to Step 10.

SECTION 4.0: APPENDICES  
INTRODUCTORY REMARKS  
All appendices (except Appendix 4.5 ), focus on specific installation issues or various situations of  
interest to the user. Each deals with a separate aspect of integrating the current HS into the described  
system environment. For completeness, all possibilities of interest are listed here, although some of  
the topics have already been discussed thoroughly in the manual.  
Appendix 4.5 extends the brief data cable parameter statement made in Section 1.0 Introduction,  
1.4 Subunit Highlights. Additional items related to data port cable specifications are covered.  
APPENDIX 4.1  
HS ADDITION TO AN EXISTING CONFIGURATION  
(No Hot Switch Currently Installed)  
Adding a hot switch to an existing system configuration that has no hot switch can increase the number of  
Sercom ports required beyond the obvious one-port increase needed when the hot switch is added. Issues  
associated with Sercom port requirements are discussed in the first section below. The second section  
deals with SEU port requirement issues based upon the final Sercom port population.  
Sercom Port Requirements  
The “final count” for the number of Sercom ports required (on each duplicate switch**) can vary depend-  
ing upon your current system configuration (prior to adding a hot switch). At a minimum, the final  
Sercom port count will increase by one, as noted in the previous paragraph.  
If an existing CC1 has two Sercom cards, and all 16 ports are used, then adding a hot switch will require  
the addition of another Sercom card. That means three Sercom cards are installed in each switch.  
The number of Sercom ports required (starting from your current base count) increases by “one” for  
each of the following circumstances that apply:  
Addition of the hot switch = 1 port  
Connection to a network (NIU) = 1 port  
If your standalone configuration is to become one of several nodes on a network, the connection to  
the NIU will require a Sercom port. If your configuration was already a node on a network, that port  
was included as part of your current base count.  
Access Control Device = 1 port  
Any access control device, formerly connected to a CC1 COM port, must now be connected to a  
Sercom port on the CC1 unless you have utilized the COM 2 port option described in Figure 1-6  
(see item [1] of Appendix 4.2 for additional information).  
If each circumstance above is applicable, the final Sercom port count will be three more than the starting  
base number. If the increase in Sercom ports required exceeds the number of ports available, it will be  
necessary to add another Sercom card to the 9700-CC1 (as well as to the duplicate switch).  
** Keep in mind that an additional 9700-CC1 is required when a hot switch is added to a configuration.  
The added CC1 is configured as a duplicate backup of the current switch.  
SEU Port Requirements  
With one exception, the general statement can be made that one SEU port is needed to interface one  
Sercom port. The exception arises because all cabling from each Sercom port does not go to an equal  
number of SEU input ports. The one-port exception is the data line connection where the hot switch is  
attached to the CC1. The addition of the hot switch does use a Sercom port (port 5 on the CC1) on the  
CC1-side of the Sercom-SEU port interface. However, the data line coming from that connection does  
not go to an SEU port at all. Instead, it goes to a communication port on the CM9760-CCC subunit of  
the hot switch. The result is that the total number of SEU ports needed to interface the total number of  
Sercom ports on a switch is one less than the Sercom port “final count” (determined above).  
NOTE: An interesting example occurs if you configure a basic CC1 that already utilizes 16  
ports. The addition of a hot switch requires 16 + 1 or 17 Sercom ports, which, in turn, requires  
the addition of another Sercom card to the CC1. However, you still need only one SEU unit to  
interface this configuration (16 ports) as one of the 17 Sercom ports on the CC1-side is not  
reflected in the total number of ports required for duplication at the SEU-side. Under this unique  
circumstance, an additional SEU unit is not required.  
Concluding Remarks  
Other than considering port requirements for the CC1, the SEU, and related equipment items, a  
duplicate CC1 is necessary (already mentioned). Once all equipment requirements are met, cabling is  
installed according to the instructions in the manual. Likewise, identical configuration files are programmed  
and loaded onto the interfaced CC1 units. Once these items are taken care of, system power can be  
applied and the hot switch will, if configured for default, engage the system in A-side control (Master),  
B-side backup (Slave), synchronous-mode operation.

APPENDIX 4.2 HS UPDATE  
(Previous Model of Hot Switch Installed)  
The previous model of the hot switch has existed for some time. Those acquainted with its opera-  
tional characteristics know the uses and characteristics of a hot switch. This is an advantage, on one  
hand, compared to those not so acquainted. On the other hand, that advantage is somewhat eroded  
by the fact that there are some major differences involved in the hookup and use of the new HS.  
Ingrained familiarity with the previous model can lead to simple mistakes in installing and operating  
the current model.  
To ease the transition process for those migrating to the current hot switch, Figure A4-1 highlights the  
connection similarities and differences between previous and current HS models.

Figure A4-1. Hot Switch Comparison Summary  
The intervening connections between CC1 Source and HS Destination outputs in the previous hot  
switch were implemented using a combination of specialized cabling and hardwired paths. This  
resulted in a more or less fixed relationship between the Source and Destination connections.  
The Source and Destination relationships in the current hot switch are defined by the connection  
cabling alone. The result is a more flexible hot switch. This flexibility can be seen in Figure A4-1.  
Even so, you can set up the Source-Destination relationships of the connectors for the current hot  
switch in the exact same manner as was done in the previous hot switch. This relationship  
equivalency can between the previous and current hot switch can be read off directly from  
Figure A4-1 for the current hot switch as follows:

of the PC w/MGR and, if desired, an ASCII Control Device interfaced via a Pelco DT, for  
example. The same relationship can be repeated in the current HS via the COM 1 and COM 2  
Destination ports (located on the CPS) for the devices just mentioned, which are shown in  
Figure A4-1. Note that COM 1 is usually reserved for the connection of the PC w/MGR in the  
current HS. What is new is that the current HS allows an alternate choice (RS-232 instead of  
RS-422) for the Data Line connection between the Source COM ports and the CC1 (A & B) DB9  
ports located in the CCC. This choice was not available for the previous hot switch.  
If you make this choice, however, the COM 2 (DT) Destination connection located on the CPS  
and shown in Figure A4-1 cannot be used. This is because one of the Source COM ports must  
be available for the connection of the PC w/MGR. The choices available for COM 2 port use are  
covered in Figure 1-6.  
2. Sercom Port Expansion  
Six more SEUs (in addition to the two referenced in Figure A4-1) can be added by simply  
connecting them to the hot switch common bus. This generously allows for any future expansion  
of Sercom port use.  
APPENDIX 4.3 HS UPDATE (Current Model Hot Switch Installed)  
The steps described in Table E of the manual contain the general procedure to follow when updating  
the hardware and/or software of an existing hot switch configuration. The following comments  
supplement the information found there:  
1. The “NOTE” located at the end of Table E identifies the steps in the table to follow as a general  
procedure in case of a failure of one or the other CC1.  
2. Be mindful of the considerations raised in Appendix 4.1. Is the node environment changing from  
single to multi-node? Are other equipment changes being made that affect configuration files or  
equipment cabling?  
3. Once satisfied that the impact of all changes are accounted for, then the side under repair or  
update can be powered up.  
4. It should be noted that it is possible to update one side of a hot switch configuration at a time  
without bringing the entire system down.

APPENDIX 4.4 HS AND NETWORK-INTERFACED CONFIGURATIONS  
Below are node-specific connections of NIU configurations, where each node is hot-switched.  
Note the following points, which are also reflected in Figure A4-2:  
1. Each CC1 port connection to the HS (on its respective node) stays at port 5 (standalone  
configuration) while the NIU connection (via the SEU) is connected to port 6 on each CC1.  
2. The port 6 Sercom connection of the NIU from each CC1 node (in ascending node order) is  
attached to the system NIU (in ascending port order), starting at NIU Sercom-port 5. It arrives  
there via routing through the SEU, as shown in Figure A4-2.  
3. Each node, with respect to the HS, is essentially independent of the NIU. That is, any node, at  
any time, can be taken off the network without bringing the network down. Node-specific  
procedures, such as those described in this manual, can be performed without affecting NIU  
operation. It should be noted, however, that the PC w/MGR, along with the diagnostic keyboard  
and monitor are normally connected to the “NIU” CC1. This means that available diagnostic  
screen information is less informative than that available when the diagnostic peripherals are  
attached directly to the node in question.

Interfacing network nodes with a hot switch (illustrated in Figure A4-2) can be extended to include the  
NIU itself. Figure A4-3 keeps the same node structure shown in Figure A4-2, except that now a hot  
switch interfaces the NIU. Note that the equipment numbers for hot switches contained in the respec-  
tive port definition files for the NIU and the Nodes themselves are different. These are equipment  
numbers chosen for that specific configuration in order to differentiate between a hot switch hooked to  
a controlling Network NIU from one connected to a regular node (interfacing CC1s) within a network.

APPENDIX 4.5 DATA CABLE PARAMETERS  
NOTE: For short distances  
Data communication cables are used in the CM9760 system to connect required equipment to  
that exceed the cable length  
supplied, you might consider  
the use of CAT 5 cable (for  
distances up to 300 feet). This  
cable is RS-422 compliant (up  
to the length mentioned) and  
is used primarily for Ethernet  
connections within networks.  
Moreover, it is readily available  
(because of demand) and cost  
is reasonable (because it is  
less difficult to manufacture).  
appropriate data communication ports on the CC1, which are RS-232 or RS-422 driven.  
The characteristics of the cable chosen (if not supplied) depends, first of all, on the driver type it interfaces.  
For RS-232 driven ports, such as COM 1 and COM 2 found on the CM9700-CC1, the cable used  
must meet less stringent communication requirements than that required for RS-422 driven  
ports. The cable must support for RS-232 communications must support the following driver  
characteristics:  
1. It is single ended – one driver and one receiver.  
2. It is unbalanced-a voltage level with respect to system ground drives the communications  
link.  
3. It is limited to low data rates.  
Figure A4-4  
INFORMATION BOX  
4. It is limited to local use: 50 feet or less for synchronized data; 100 to 200 feet for asynchro-  
nous data.  
BPS or bps means =  
bits per second  
Baud =  
For RS-422 driven ports, such as the 32 Sercom ports on the rear of the CC1, the cable chosen  
by the user must support the following driver characteristics:  
# of signal changes per second  
In the recent past, bps and baud  
rate were equivalent, that is, 300  
bps and 300 baud, for example,  
were the same. Two things  
happened which eventually sepa-  
rated the use of bps and baud as  
being equal.  
1. It is single ended, multi-drop capable.  
2. It is balanced-a differential voltage drives the communications link.  
3. It handles relatively high data rates. There is a trade off between data rate and cable length  
(theoretically, up to 4,000 feet [1,220 m] @ 100Kbps) (see Figure A4-6).  
100 MBPS  
1. It became physically possible  
to transmit more than one bit  
per signal change through  
variations in amplitude, fre-  
quency, and/or phase.  
10 MBPS  
1MBPS  
2. A physical bandwidth limit on  
voice-grade phone lines made  
it difficult to reach baud rates  
greater than 2400. Almost all  
modems do not operate at a  
speed greater than this.  
DATA  
RATE  
100 KBPS  
Therefore, a modem operating at  
a Pelco referenced baud rate of  
9600 is, most likely, a 2400 baud  
modem operating at 9600 bps  
(or a 4:1 compression ratio or 4 x  
2400 = 9600) because of the bps  
manipulation mentioned above.  
Therefore, for higher speed mo-  
dems and for the chart illustrated  
in Figure A4-4, modem speeds are  
normally listed and referenced at a  
bps rate. For convenience, Pelco  
refers to modem speeds in all its  
communication parameter lists, by  
using the term baud rate (a misno-  
mer), even though the numerical  
portion of the reference is actually  
in “bps”. In Figure A4-4 the approxi-  
mate baud rate range of Pelco  
equipment is highlighted against  
the bps per distance chart.  
ABOUT 19,200 BPS  
MOST PELCO 9760 COMMUNICATION  
DEVICES FALL WITHIN THIS BPS RANGE.  
FOR CONVENIENCE, PELCO REFERS TO  
THESE BPS RATES AS BAUD RATES,  
WHICH, IN MOST CASES, EXCEPT FOR  
2,400 IS MORE LIKELY THAN NOT,  
MISNOMER. SEE THE INFORMATION

4. It is used for both local and remote hookup of system devices; for example, remote hookup  
of 9760 keyboards attached to the CC1.  
Most of the time, connection cables are supplied with the device. As long as the supplied cable is  
appropriate, no problem arises. If the cable length needed is greater than that supplied, a problem  
arises for the installer/specifier as to the type of cable to use. One of the most common hookup exten-  
sions is the example already referred to: the remote hookup of a 9760 keyboard. The following high-  
lights the issues involved and ends with some recommendations.

Remote Hookup of the CM9760-KBD  
The 9760 keyboard comes with associated cables and a CM9505UPS (universal power supply) to  
supply the 12V needed to power the keyboard. The standard hookup for the keyboard to the matrix  
switch (CC1) is shown in Figure A4-5.

For remote installation of the keyboard, the user must supply a cable of appropriate length that supports  
the TIA/EIA-422-B (RS-422) communication standard. The example in Figure A4-6 shows a keyboard  
placed 2,000 feet (610 m) from the CC1 via the user-supplied cable. Junction boxes (phone boxes) are  
used to facilitate the RJ-45-to-cable connection points at either end of the run. Note that only signal  
wires and ground are run through the cable itself (five of the six available wires are used in the  
example). The transformer serves to pass on the data signal and to supply power to the keyboard at the  
keyboard end.

Although the communication link can be as far away as 4,000 feet (1,220 m) (per Figure A4-4), this is  
theoretical and Pelco recommends that for distances greater than 2,000 feet (610 m) a  
CM9505UPS-422 power supply with data repeater be used.

plications. TableA4-A is taken directly from the FULL TECHNICAL SPECS page in Belden’s Cable Catalog located on their company web site.

* TIA/EIA-422-B is the full name of the current standard for what is commonly referred to as RS-422. The prefix “RS”, which stands for  
“recommended standard”, was used by the EIA (Electronic Industries Association) as the name for some of its standards. The “RS-” prefix  
was dropped by the EIA in 1986 and standards were simply referred to with the EIA- prefix. In 1988 TIA (Telecommunication Industries  
Association) was a working group of the EIA and the reference evolved to a combined EIA/TIA- prefix. When TIA became ANSI (American  
National Standards Institute) accredited, the acronym order was reversed to TIA/EIA-. In 1992 TIA spun off from EIA and merged with US  
Telecommunications Suppliers Association (USTSA). From about that time to the present, the full standard has been referenced as ANSI/  
TIA/EIA-422-B, where “B” is the latest revision of the standard. Normally the standard is written simply as TIA/EIA-422. In all probability, that  
will be shortened to just TIA-422, at some point in the future. However, everyone has used the “RS-” prefix reference for so long that it may  
be some time before its use disappears, if at all.
