Introduction  
About the CrossPoint Plus Series Matrix Switchers  
The Extron CrossPoint Plus Series Matrix Switchers are ultra-wideband analog  
RGBHV matrix switchers that distribute any input to any combination of outputs.  
The matrix switchers can route multiple input/output configurations  
simultaneously. There are six series available that offer a variety of matrix sizes:  
• CrossPoint Plus 84 (eight inputs by four outputs)  
• CrossPoint Plus 88 (eight inputs by eight outputs)  
• CrossPoint Plus 124 (twelve inputs by four outputs)  
• CrossPoint Plus 128 (twelve inputs by eight outputs)  
• CrossPoint Plus 168 (sixteen inputs by eight outputs)  
• CrossPoint Plus 1616 (sixteen inputs by sixteen outputs)  
Each series offers two models: HV for switching RGBHV signals, and HVA models  
for switching RGBHV and two-channel stereo audio (balanced and unbalanced).  
All models also switch RGBS, RGsB, RsGsBs, HDTV, component video, S-video,  
and composite video (figure 1-1). The audio switching can either be linked with  
the video (audio follow) or independent of the video (audio breakaway).  
Adjustable input audio gain and attenuation compensates for level differences  
between audio inputs.  
The CrossPoint Plus Series are single box solutions to 425 MHz (-3dB) routing  
applications. Each input and output is individually isolated and buffered, and any  
input(s) can be switched to any one or all outputs with virtually no crosstalk or  
signal noise between channels.  
The CrossPoint Plus 84, 88, 124, and 128 Matrix Switchers are housed in rack-  
mountable, 3U high, 19” wide metal enclosures. The CrossPoint Plus 168 and 1616  
are in a 6U high enclosure. The appropriate rack mounting kit is included with  
each switcher. Each model has an internal 100VAC to 240VAC, 50/60 Hz, 30 watts  
(CrossPoint Plus 84, 88, 124, and 128) or 36 watts (CrossPoint Plus 168 and 1616),  
auto-switchable power supply that provides worldwide power compatibility.

Introduction, cont’d  
CrossPoint Plus Series delivers the highest performance and the most cost-  
effective solution.  
Digital Sync Validation Processing (DSVP™) — In critical environments or  
unmanned, remote locations, it is vital to know that sources are active and  
switching. Extron’s exclusive DSVP confirms that input sources are active by  
scanning all sync inputs for active signals. DSVP provides instantaneous  
frequency feedback for composite sync or separate horizontal and vertical  
sync signals via the switcher’s RS-232/422 port. The frequency information  
can be displayed on any control system or in a Windows®-based control  
program on a local-area network (LAN) or internet (IP) connection  
(figure 1-2).

Channel to channel isolation — The CrossPoint Plus Series provides excellent  
isolation between channels and extremely low electromagnetic emissions—  
perfect for minimizing signal leakage in high security or government  
environments.  
I/O grouping — Allows the matrix to be virtually divided into smaller sub-  
switchers, making installation and control easier. I/O grouping allows  
specific outputs, such as those designated for a specific video format, to be  
grouped together.  
Triple-Action Switching™ (RGB delay) — RGB delay blanks the screen when the  
matrix switcher switches to a new source. The new sync signals precede the  
RGB signals, so there is no noise-filled scramble shown during the transition.  
The time delay between the RGB and sync signals is user adjustable up to  
five seconds under RS-232/422 control.  
View mode — View mode allows the user to easily see which individual inputs  
and outputs are actively connected under front panel or RS-232/422 control.

Operational flexibility — Operations such as input/output selection, setting of  
presets, and adjustment of audio levels can be performed on the front panel  
or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote  
control via a PC, RS-232 capable PDA, or control system.  
•
QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint Plus  
series QS-FPC feature supports touch-of-a-button input and output selection,  
preset creation and selection, and audio gain and attenuation control.  
•
Windows-based control program — Extron’s Windows-based control  
program provides a versatile range of operational options with its graphical  
interface and drag-and-drop/point-and-click operation. The Windows-based  
control program also has an emulation mode that lets you create a switcher  
configuration file at the home office and then download it for use by the  
switcher on site.  
•
Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s  
SIS for easy programming and operation.  
Audio gain/attenuation — Users can set the input level of audio gain or  
attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front  
panel. Individual input audio levels can be adjusted so there are no  
noticeable volume differences between sources (figure 1-3).

Remote control — The CrossPoint Plus switchers are remote controllable, using the  
MKP 1000 master control keypad and any combination of MCP 1000 slave  
control panels and/or MKP 1000 slave control keypads. The remote control  
devices are easy to use and provide tactile buttons for quick selection. Each  
MCP 1000 can be used for one-touch switching for a particular output and  
selecting global presets. Each MKP 1000 dedicated to an output can be used  
to select a different input for that output or to select a preset.  
Labeling — Extron’s label software ships with every Extron matrix switcher. You  
can create labels to place alongside the front panel input buttons and output  
buttons, with names, alphanumeric characters, or color bitmaps for easy and  
intuitive input and output selection. Alternatively, labels can be made with  
any Brother® P-Touch™ or comparable labeler.  
Executive mode (front panel security lockout) — If a CrossPoint Plus Series  
Switcher is installed in an open area, where operation by unauthorized  
personnel may be a problem, a security lock-out feature can be implemented.  
When the front panel is locked, a special button combination is required to  
unlock the front panel controller before it can be operated.  
Rack mounting — The switchers are mountable in any conventional 19” wide rack.  
Power — The 100VAC to 240VAC, auto-switchable, internal power supply of the  
CrossPoint Plus Series provides worldwide power compatibility.

Installation  
Rack Mounting the Switcher  
The CrossPoint Plus 84, 88, 124, and 128 Matrix Switchers are housed in rack-  
mountable, 3U high, 19” wide metal enclosures. The CrossPoint Plus 168 and 1616  
are in 6U high enclosures. The appropriate rack mount kit is included with each  
switcher. Rack mount the switcher as follows:  
1.  
Insert the switcher into the rack, align the holes in the mounting bracket with  
those of the rack.  
2.  
Secure the switcher to the rack using the supplied machine screws.  
Cabling and Rear Panel Views  
All connectors are on the rear panel. Figure 2-1 shows the CrossPoint Plus  
128HVA. The CrossPoint Plus 84, 88, and 124 are housed in the same 3U enclosure,  
but have fewer input and/or output connectors to accommodate the different  
matrix sizes each provides. Figure 2-2 shows the CrossPoint Plus 1616HVA. The  
CrossPoint Plus 168 is housed in the same 6U enclosure, but has fewer output  
connectors to accommodate its 16x8 matrix.

Video input and output connections  
All video input and output connections to the CrossPoint Plus switchers are  
made with female BNC connectors. Some types of video output devices do not  
have BNC video output connectors. For these cases, a suitable cable or  
connector adapter is necessary between the device output connector and the  
BNC input connector of the CrossPoint Plus.  
RGBHV video inputs — Connect RGBHV video inputs to these BNC  
2

connectors for each input.  
RGBHV video outputs — Connect RGBHV video outputs to these BNC  
connectors for each output.  
The CrossPoint Plus Series switchers can also switch RGBS, RGsB, RsGsBs,  
component video, S-video, or composite video by using four, three, two, or one  
BNC. If switching a video format other than RGBHV, ensure that the same  
video planes (R, G, B, H/HV, and/or V) are used on the switcher output as on  
the input.  
The CrossPoint Plus Series Matrix Switchers do not alter the video signal in  
any way. The signal output by the switcher is in the same format as the input.  
Audio input and output connections (HVA models only)  
The captive screw connector can easily be inadvertently plugged partially  
CAUTION  
into one receptacle and partially into an adjacent receptacle. This  
misconnection could damage the audio output circuits. Exercise care to  
ensure the captive screw connector is plugged into the desired input or  
output.  
Connections for balanced and unbalanced audio inputs — Each input has a  
3.5 mm, 5-pole captive screw connector for balanced or  
unbalanced stereo audio input. Connectors are included  
with each CrossPoint Plus switcher, but you must supply  
the audio cable. See figure 2-3 to wire a connector for the  
appropriate input type and impedance level. High  
4
impedance is generally over 800 ohms.

Figure 2-3 — Captive screw connector wiring for inputs  
When making connections for the CrossPoint Plus Series Switcher from  
existing audio cables, see figure 2-4. A mono audio connector consists of the  
tip and sleeve. A stereo audio connector consists of the tip, ring and sleeve.  
The ring, tip, and sleeve wires are also shown on the captive screw audio  
connector diagrams, figure 2-3 and figure 2-5.  
The audio level for each input can be individually set, via the front panel or  
RS-232/422, to ensure that the level on the output does not vary from input to  
input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5,  
Matrix Software, for details.

CAUTION  
By default, the audio output follows the video switch. Audio breakaway,  
commanded via the front panel, under RS-232/422 control, or Windows-  
based control program, allows you to select from any one of the audio input  
sources. See chapter 3, Operation, chapter 4, Programmer’s Guide, and  
chapter 5, Matrix Software for details.

If desired, attach an MCP 1000 remote control panel master unit to the  
switcher’s RS-232/RS-422 connector. You can also attach an MKP 1000 remote  
keypad or MCP 1000 slave unit to the MCP 1000 master unit. Refer to the  
MCP 1000 Remote Control Panel User’s Manual, part # 68-456-01, and the MKP  
1000 User’s Manual, part # 68-355-01, for details.  
See chapter 4, Programmer’s Guide, for definitions of the SIS commands and  
chapter 5, Matrix Software, to install and use the control software.  
The CrossPoint Plus Series Matrix Switchers are factory configured for  
RS-232 control. To use the switcher under RS-422 control, an internal cable  
must be moved. See appendix B for the procedure for shifting the cable.

control panel. The control buttons and input/output (I/O) selection buttons and  
indicators are grouped on the right side of the panel.  
While the number of inputs and outputs varies depending on the size of the  
matrix, there are only two front panel arrangements. The CrossPoint Plus 84,  
88, 124, and 128 have 12 input buttons and 8 output buttons (figure 3-1).  
The CrossPoint Plus 168 and 1616 have 16 input buttons and 16 output  
buttons (figure 3-2).

Definitions  
The following terms apply to Extron Matrix Switchers, and are used throughout  
this manual:  
Tie — An input-to-output connection.  
Set of ties — An input tied to two or more outputs. (An output can never be  
tied to more than one input.)  
Configuration — May consist of one tie or one or more sets of ties.  
3-2  
CrossPoint Plus Matrix Switchers • Operation  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Current configuration — The configuration that is currently being used (also  
called configuration 0).  
Global memory preset — A configuration that has been stored. Up to 16  
global memory presets can be stored in memory. The input buttons select  
the desired preset memory location to load or retrieve a preset. When a  
preset is retrieved from memory, it becomes the current configuration. One  
preset can be assigned to each input button. (On CrossPoint Plus 84, 88, 124,  
and 128 models, presets 13 through 16 can only be stored and retrieved via  
the RS-232/422 link.)  
Input buttons, output buttons, and LEDs  
If the switcher has fewer inputs and outputs than input and output buttons  
and LEDs, only the applicable buttons and LEDs perform the function of  
selecting and identifying an input or output.  
Input 1 through 12 (16) buttons and LEDs — The input buttons have two  
independent functions: to select an input and to select a preset. The input  
LEDs identify selected inputs. A more detailed explanation of the two  
functions is included in Front Panel Operations beginning on page 3-5.

2
Output 1 through 8 (16) buttons and LEDs — The output buttons and LEDs  
select and identify outputs. On HVA models, the output LEDs also display  
the user-adjustable audio level of the selected input. A more detailed  
explanation of the two functions is included in Front Panel Operations  
beginning on page 3-5.  
Control buttons and LEDs  
Enter button — The Enter button saves changes when you set up a new

configuration. To create a simple configuration, specify video, audio, or both  
7
8
1
(see controls ( ) and ( )); press the desired input button ( ); press the  
2
desired output button(s) ( ); and press the Enter button.  
Preset button and LED — The Preset button saves a configuration as a preset  
or recalls and makes current a previously defined preset. The Preset LED  
indicates save mode when it is blinking and recall mode when it lights  
steadily.  
View button and LED — The View button selects a view-only mode that  
allows the display of the current CrossPoint Plus configurations and provides  
a way to mute and unmute video and audio outputs. The view-only mode  
helps prevent changing configurations by accident. The View LED indicates  
that the CrossPoint Plus is in view-only mode.  
1
2
In view-only mode, pressing any input button ( ) or output ( ) button  
lights the LEDs for the input and all outputs that are a part of that set of ties.  
Pressing the button for any unassigned output lights only the output LEDs for  
all of the unassigned outputs. No input LED is lit.  
As a secondary function on HVA models, the View button decrements the  
audio level of the selected input. In audio adjustment mode, the View LED  
indicates a negative (-) attenuation value. A more detailed explanation of  
audio level adjustment is included in Viewing and adjusting the input audio level  
(HVA models only) on page 3-15.  
Esc button and LED — The Esc button cancels operations or selections in  
progress and resets the front panel LEDs. The Esc button does not reset the  
current configuration, the RGBHV and Audio LEDs, any presets, or any audio  
gain/attenuation settings. The Esc LED flashes once after the Esc button is  
pressed and released to indicate the escape function.

As a secondary function on HVA models, the Esc button increments the audio  
level of the selected input. In audio adjust mode, the Esc LED indicates a  
positive (+) gain value. A more detailed explanation of audio level  
adjustment is included in Viewing and adjusting the input audio level (HVA  
models only) on page 3-15.  
I/O controls  
When creating or viewing a configuration, you must specify whether the  
configuration applies to video, audio, or both. This is done with the RGBHV (  
and Audio ( ) buttons.  
7
)
8
Although present, the Audio button has no function on HV models.  
RGBHV button and LED — The RGBHV button selects and deselects video  
for a configuration being created or viewed. The RGBHV LED lights to  
indicate that video is available for configuration or viewing.  
7
8
Audio button and LED — The Audio button selects and deselects audio for a  
configuration that is being created or viewed. The Audio LED lights to  
indicate that the audio configuration follows the video configuration. The  
Audio LED blinks to indicate that the audio configuration is broken away  
from the video configuration.  
As a secondary function, the Audio button selects the audio level display/  
adjust mode. Press and hold the Audio button until the Audio LED begins to  
blink. If the RGBHV LED was lit, it turns off. Select an input. The current  
audio level setting for the selected input is displayed in the output LEDs. The  
audio level for the selected input can be incremented and decremented by  
5

pressing the View ( ) and Esc ( ) buttons. A more detailed explanation of  
audio level adjustment is included in Viewing and adjusting the input audio level  
(HVA models only) on page 3-15.  
Front panel I/O label windows  
Input and output label panels — These translucent panels can be removed  
9
and replaced to insert labels behind the panels. To remove a panel, insert the  
Phillips-head end of an Extron tweeker or small Phillips-head screwdriver  
into the hole in one end of the panel, and gently slide the tab on the edge of  
the panel out of the recess in the switcher housing.  
Input and output labels can be created easily with Extron’s button label  
generator software, which ships with every Extron Matrix Switcher, or with  
any Brother P-Touch labeler. Each input and output can be labeled with  
names, alphanumeric characters, or even color bitmaps for easy and intuitive  
input and output selection (figure 3-3). See chapter 5 for details on using the  
label software.

Front Panel Operations  
The following paragraphs detail the power-up process and then provide sample  
procedures for creating ties, sets of ties, and configurations; changing a  
configuration; viewing ties, sets of ties, and configurations; saving a preset;  
recalling a preset; and viewing and adjusting the audio level.  
Power  
On all models, power is automatically applied when the power cord is connected to  
an AC source. When AC power is applied, the switcher performs a self-test that  
blinks the front panel LEDs during the test. An error-free power up self-test  
sequence leaves the RGBHV and/or the Audio LED(s) on, depending on the  
model, and all other LEDs off.  
The current configuration and all presets are saved in non-volatile memory. When  
power is applied, the last current configuration is retrieved. The previous presets  
remain intact.  
If an error occurs during the self-test, the switcher locks up and will not operate. If  
your switcher locks up on power-up, call the Extron S3 Sales & Technical Support  
Hotline.  
I/O grouping  
I/O grouping is an RS-232/422 controlled feature that allows you to subdivide the  
front panel control of the matrix into four smaller functional subswitchers. Inputs  
and outputs can be assigned to one of four groups or not assigned to any group  
(figure 3-4). Once assigned to a group, inputs and outputs can only be tied within  
that group from the front panel. For example, a front panel operator cannot tie an  
input that is assigned to group 1 to an output that is assigned to group 2.  
Ungrouped inputs and outputs can be switched to outputs and inputs in any  
group.

Operation, cont’d  
The I/O groups can be set up only by using the RS-232/422 port and either the SIS  
or the Windows control program. Ties between groups (an input in group 1 tied to  
an output in group 2) can be created under RS-232/422 control. Presets can also be  
created under RS-232/422 control that tie inputs and outputs across group  
boundaries. These presets are selectable from the front panel.  
Suggested applications for the I/O grouping feature include:  
•
Segregating specific video formats to prevent an input in one video format  
from being inadvertently applied to an output device that supports another  
video format.  
•
•
Segregating input and output devices that are in separate rooms.  
Isolating video from being displayed on specific output devices for  
operational security reasons.  
The I/O groups created under RS-232/422 control can result in front panel  
indications that are different from indications when grouping is not used. In the  
following paragraphs, the effects of I/O grouping on the front panel indications are  
included.  
Creating a configuration  
The current configuration can be changed using the front panel buttons. To change  
the current configuration, do the following:  
1.  
2.  
3.  
Press the Esc button to clear any input LEDs, output LEDs, or control LEDs  
that may be on.  
Select to configure video, audio, or both by pressing the RGBHV and/or  
Audio buttons.  
Select the desired input and output(s) by pressing the input and output  
buttons.  
4.  
5.  
Press and release the Enter button.  
Repeat steps 1 through 4 to create additional ties until the desired  
configuration is complete.  
1. Only one video input and one audio input can be tied to an output.  
2. If a tie is made between an input and an output, and the selected output  
was previously tied to another input, the older tie is broken in favor of the  
newer tie.  
3. To indicate current ties, output LEDs light when an input is selected. To  
clear unwanted outputs press and release the associated output buttons.  
4. If, when configuring video and audio ties, the Audio LED blinks and the  
RGBHV LED is on after selecting an input or output, the LEDs indicate  
audio breakaway, meaning that the audio ties are not the same as the video  
ties for that input.  
5. If an input with no tie is selected, only that input’s LED lights.  
6. When the RGBHV and Audio LEDs are on, if an input with an audio tie  
but no video tie is selected, the input’s LED lights and the Audio LED  
blinks.  
7. As each output is selected, the associated output LED blinks to indicate a  
tentative tie. LEDs for output(s) that were already tied to the input light  
steadily. Outputs that are already tied can be left on, along with new  
blinking selections, or toggled off by pressing the associated output  
button.

8. If the input button for a grouped input is pressed, and then the output  
button for an output in a different group is pressed, the associated output  
LED blinks twice and goes out to indicate that output cannot be tied to the  
input. The associated input LED remains lit.  
Example 1: Create a set of video and audio ties  
See Figure 3-5 and the following steps for an example in which input 5 is tied to  
outputs 3, 4, and 8.  
This example assumes that there are no ties in the current configuration.

Viewing a configuration  
The current configuration can be viewed using the front panel buttons. The view-  
only mode prevents inadvertent changes to the current configuration. View-only  
mode also provides a way to mute video and audio outputs (see Muting and  
unmuting video and/or audio in this chapter.  
To view the current configuration, do the following:  
1.  
Press the Esc button to clear any input LEDs, output LEDs, or control LEDs  
that may be on.  
2.  
3.  
Press and release the View button.  
Select video, audio, or both to view by pressing the RGBHV and Audio  
buttons.  
4.  
Select the desired input or output(s) for which ties need to be viewed by  
pressing the input and output buttons.  
1. To see all ties of the current configuration, press and release each input  
and output button, one at a time, with the RGBHV and Audio LEDs on.  
2. If you select a grouped input or output in view-only mode, all of the input  
and output LEDs in the group flash for half a second and then the current  
configuration is displayed in the normal manner.  
3. In view-only mode, you can view video and audio, video-only, or audio-  
only ties. Pressing and releasing the RGBHV and Audio buttons toggles  
each on and off.  
4. If, when you view video and audio ties, the Audio LED blinks and the  
RGBHV LED is on after selecting an input or output, the LEDs indicate  
that the audio ties are not the same as the video ties for that input (audio  
breakaway is active). Toggle the RGBHV LED off by pressing and  
releasing the RGBHV button.  
5. When you enter view-only mode, the output LEDs turn on for all outputs  
without ties. Likewise, when an output button is pushed for which there  
are no ties, the output LEDs turn on for all outputs without ties. The  
blinking Audio LED indicates audio breakaway for one or more of those  
outputs.

Using presets  
The current configuration (configuration 0) can be saved as a preset in any 1 of 16  
preset memory addresses. Each CrossPoint Plus switcher has as many presets  
available from the front panel as input buttons. On the CrossPoint Plus 84, 88, 124,  
and 128, the extra presets can be saved or stored via the RS-232/422 link only.  
1. Only the audio and video ties are stored and recalled; audio gain settings  
are not saved, and they do not change when a preset is recalled.  
2. Presets cannot be viewed from the front panel unless recalled as the  
current configuration. Presets can be viewed using Extron’s Windows-  
based control program, see chapter 5, Matrix Software, for more details.  
3. The current configuration and all presets are stored in non-volatile  
memory. When power is removed and restored, the current configuration  
is still active and all presets are retained.  
4. When a preset is recalled, it replaces the current configuration, which is  
lost unless it is also stored as a preset. The recalled preset overwrites all of  
the current configuration ties in favor of the preset configuration ties.

Both the RGBHV and Audio LEDs light.  
Executive mode (front panel security lockout)  
The executive mode limits the operation of the CrossPoint Plus switcher from the  
front panel. When the switcher is in executive mode, all of the front panel  
functions are disabled except for the view-only mode functions (see Viewing a  
configuration on page 3-9). Other than in view-only mode, if the user pushes a front  
panel button when the switcher is in executive mode, that button’s associated LED  
flashes twice and goes out.  
To toggle executive mode on or off, press and hold the RGBHV and Audio buttons  
for approximately two seconds. The RGBHV and Audio LEDs blink twice to  
indicate the mode change. Release the RGBHV and Audio buttons. To toggle the  
executive mode state again, press and hold the RGBHV and Audio buttons again.

System reset to factory defaults  
To reset the switcher to the factory default settings, press and hold the Esc button  
on the front panel while AC power is being applied. Continue to hold the Esc  
button until the power up sequence is completed (all LEDs turn off, the Video and  
Audio LEDs turn on, the Esc LED blinks, and the Power LED (if equipped) turns  
on). System reset clears all ties and presets, the RGB delay, the mutes, and the I/O  
grouping to the factory defaults and sets all audio gain levels to unity gain (+0dB).  
Rear Panel Controls  
The CrossPoint Plus matrix switchers all have sync termination switches on the  
rear panel for inputs 1, 3, 5, and 7 on the CrossPoint Plus 168 and 1616 models and  
inputs 1 through 4 (figure 3-20) on the CrossPoint Plus 84, 88, 124, and 128 models.  
The switches provide a way to condition non-TTL sync levels greater than 5Vp-p,  
enabling the sync to be properly passed from input to selected output(s). The  
matrix switchers have two sets of sync termination switches; one for horizontal or  
combined sync and a second set for vertical sync.

Figure 3-20 — Rear panel sync termination switches  
Each switch provides the option of selecting either 510 ohms or 75 ohms. The  
75 ohms position is required only for an input with non-TTL sync, greater than  
5V p-p. The normal position is 510 ohms.  
An input that produces an out of sync display, a display that is rolling  
vertically and/or tearing horizontally, could indicate a non-TTL sync input. A  
device that is known to output non-TTL sync levels (greater than 5V p-p)  
should be connected to one of the inputs with sync termination switches, and  
the switches for that input should be set to the 75 ohm position. If you’re not  
sure, check the specifications in the user’s manual for the input device.  
Troubleshooting  
This paragraph gives recommendations on what to do if you have problems  
operating the CrossPoint Plus, and it provides examples and descriptions for some  
image problems you may encounter.  
General checks  
1.  
Ensure that all devices are plugged in and powered on. The switcher is  
receiving power if one of the input LEDs is lit.  
2.  
3.  
4.  
5.  
Ensure an active input is selected for output on the switcher.  
Ensure that the proper signal format is supplied.  
Check the cabling and make corrections as necessary.  
Call the Extron S3 Sales & Technical Support Hotline if necessary.

Plasma display S-video problem  
Extron has encountered a problem with the S-video output by some video  
conference codecs, when it is switched using a CrossPoint Plus. Some codecs  
change the DC offset on the chrominance (C) so that it is very different from the  
level on the luminance (Y). This can cause a plasma display to come up in the  
wrong size mode.  
With the matrix switcher taken out of the system, the plasma works fine. It looks  
like a Extron problem, but it is not. The matrix switcher boosts the bad codec  
output, which makes the plasma go to the wrong setting.  
Solution: Try placing an Extron video DC block adapter, part #26-495-01, on the  
luminance (Y) input to the switcher from the codec.  
Worksheets  
Rather than trying to remember the configuration for each preset, use worksheets  
to record this information. Make copies of the blank worksheets on page 3-19 and  
use one for each preset configuration. The forms accommodate all of the  
CrossPoint Plus models. Cross off all unused or inactive inputs and outputs. Use  
different colors for video and audio.  
Worksheet example 1: Entering system equipment  
Figure 3-21 shows a worksheet for a CrossPoint Plus 128 HVA in a fictional  
organization with the system hardware annotated. Inputs 10 and 11 and output 7  
have no connections in this organization, so they have been crossed out on the  
worksheet. On this example, preset 3 is used for the weekly status meeting.  
Choose your own method of notation.

The RS-232/RS-422 connector on the CrossPoint Plus Series switcher is a 9-pin D  
female connector with pin assignments as shown in figure 4-1.  
The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.  
Host-to-Switcher Instructions  
The switcher accepts SIS (Simple Instruction Set) commands through the  
RS-232/RS-422 port. SIS commands consist of one or more characters per  
command field. They do not require any special characters to begin or end the  
command character sequence. Each switcher response to an SIS command ends  
with a carriage return and a line feed (CR/LF = ), which signals the end of the  
response character string. A string is one or more characters.  
Switcher-Initiated Messages  
When a local event such as a front panel operation occurs, the switcher responds  
by sending a message to the host. The switcher-initiated messages are listed below  
(underlined).  
(C) Copyright 2002, Extron Electronics “CrossPoint/Mav/Matrix”, Vx.xx  
The copyright message is initiated by the switcher when it is first powered on.  
Vx.xx is the firmware version number.  
RECONFIG  
The reconfig message is initiated by the switcher when a front panel operation has  
occurred, an audio gain adjustment has been completed, or a memory preset has  
been recalled.  
RAM Test Failed  
ROM Checksum Failed  
EEPROM Reset (Presets/Attenuators)  
Serial EEPROM Reset (Current Settings)  
Invalid Jumpers  
If an error occurs during power-up, the switcher initiates one or more of the  
messages listed above.  
All Configuration Memory Cleared  
The memory cleared message is initiated by the switcher when a system reset has  
occurred. See System reset to factory defaults in chapter 3.

The switcher does not expect a response from the host, but, for example, the host  
program might request a new status.  
Switcher Error Responses  
When the switcher receives an SIS command and determines that it is valid, it  
performs the command and sends a response to the host device. If the switcher is  
unable to perform the command because the command is invalid or contains  
invalid parameters, the switcher returns an error response to the host. The error  
response codes are:  
E01 — Invalid input channel number (too large)  
E10 — Invalid command  
E11 — Invalid preset number (too large)  
E12 — Invalid output number (too large)  
E13 — Invalid value (out of range)  
E14 — Illegal command for this configuration  
E17 — Timeout (only caused by direct write of global presets)  
Using the Command/Response Table  
The command/response table begins on the next page. Lower case letters are  
acceptable in the command field only where indicated. Symbols are used  
throughout the table to represent variables in the command/response fields.

1. This sequence of commands forces the switcher to perform a complete backplane switch  
within 60 msecs of receipt of the Quick recall command.  
2. The switcher ignores any invalid command or non-switching commands received between  
the Start and End commands.  
3. If there is no activity for 5 seconds, the switcher returns the timeout (E17) error.  
4. The switcher disables front panel switching during this sequence of commands.  
5. The switcher returns the invalid command (E10) error if it receives the End command  
without the start command or the Quick recall command without a prior direct preset write.  
6. The switcher must receive the Quick recall command within 100 msecs of the End  
command.

Matrix Software  
Two software programs accompany the CrossPoint Plus Series switchers:  
•
The Extron Matrix Switcher+ Control Program (Extron part #29-015-01),  
which communicates with the switcher via the RS-232/RS-422 port, provides  
an easy way for you to set up ties and sets of ties.  
If your CrossPoint Plus Series switcher was previously set up for RS-232, and  
your computer comm port uses RS-422, you must change the switcher cabling  
to match the computer interface. See Appendix B, Reference Information, for  
details.  
•
The Extron Button-Label Generator, which allows you to design and print  
labels for the CrossPoint Plus front panel buttons.  
Both programs are compatible with Windows 95/98, Windows NT, Windows ME,  
and Windows 2000. Updates to these programs can be downloaded from the  
Extron Web site (http://www.extron.com).  
Matrix Switchers Control Program  
Installing the software  
The program is contained on a set of 3.5-inch diskettes, and you should load and  
run the program from the hard drive.  
To install the program from the floppy disk to the hard drive, run Setup.exe from  
the floppy disk and follow the instructions that appear on the screen. The program  
occupies approximately 1 MB (megabyte) of hard-drive space.  
By default, the Windows installation creates a C:\MTRX directory, and it places  
two icons (Matrix Switcher+ Control Program and Matrix Switcher+ Help) into a  
group or folder named “Extron Electronics”.  
The program was designed to control most Extron matrix switchers, but its  
operation is limited to the features and configuration of your  
CrossPoint Plus Series switcher.  
Using the software  
Overview  
This section is an overview of the Extron Matrix Switcher+ Control Program. The  
help function contains additional information. See Using the help system on page 5-5  
for details.  
1.  
To run the Matrix Switcher+ Control Program, double-click  
on the Matrix Switcher+ Control Program icon (shown at  
right) in the Extron Electronics group or folder.  
2.  
Click on the comm port that is connected to the RS-232/  
RS-422 port of the switcher. To set up the software without  
attaching the switcher to the computer, see Using emulation mode on page 5-5.  
The Extron Matrix Switcher+ Control Program window (figure 5-1 and  
figure 5-2) displays the current configuration of the attached matrix.  
3.  
To set up audio in follow mode (audio and video have the same tie  
configuration), select the Group box at the bottom of the window. To set up  
audio in breakaway mode (audio and video have different tie configurations),  
deselect the Group box.

Figure 5-2 — Sample program window (complete)  
4.  
To make the control program easier to use, assign a device icon to each input  
and output. Click on a box that represents an input or output, and drag the  
desired icon onto the box from the icon palette that appears.  
5.  
To create a tie, drag an input box to one or more output boxes. To remove a  
tie, drag the output box to its tied input box.  
6.  
For quick display of information on a specific input or output, place the  
cursor over that device in the control program window. The program pops  
up a window that details the connections to that device, the switching interval  
(RGB delay), and the frequency of the video signal input from or output to  
that device.  
Windows buttons  
The buttons on the right side of the window perform the following functions:  
Power — Unavailable for CrossPoint Plus Series switchers, because the switcher  
power cannot be controlled via software.
