Introduction

About the CrossPoint Series Matrix Switchers

The Extron CrossPoint Series Matrix Switchers are 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 84 (eight inputs by four outputs)

• CrossPoint 88 (eight inputs by eight outputs)

• CrossPoint 124 (twelve inputs by four outputs)

• CrossPoint 128 (twelve inputs by eight outputs)

• CrossPoint 168 (sixteen inputs by eight outputs)

• CrossPoint 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 audio gain and attenuation compensates for level differences between
audio inputs.

The CrossPoint Series are single box solutions to simple 200 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 84, 88, 124, and 128 Matrix Switchers are housed in rack­mountable, 3U high, 19” wide metal enclosures. The CrossPoint 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 84, 88, 124, and 128) or 36 watts (CrossPoint 168 and 1616), auto­switchable power supply that provides worldwide power compatibility.

Introduction, cont’d

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 control system.

• QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint 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 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 1-2).

Global memory presets — 12 (CrossPoint 84, 88, 124, and 128) or 16

(CrossPoint 168 and 1616) global memory presets are a time-saving feature
that lets you set up and store input/output configurations in advance and
then recall those configurations when needed with a few simple steps.

Switching — Individually buffered, independent matrix switched outputs with

audio follow and audio breakaway on HVA versions.

• Any input to any or all outputs

• Audio follow — Audio can be switched with the corresponding video input.

This feature allows any audio signal to be selected with any video signal
simultaneously to one or all outputs in any combination. Audio follow
switching can be done via front panel control or under RS-232/RS-422 remote
control.

• Audio breakaway — Audio can be broken away from its corresponding

video signal. Audio breakaway switching can be done via front panel control
or under RS-232/RS-422 control.

CrossPoint Matrix Switchers • Introduction1-4

Remote control — The CrossPoint 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.

Front panel security lockout (executive mode) — If a CrossPoint 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 mount — The switchers are mountable in any conventional 19” wide rack.
Power — The internal 100VAC to 240VAC, 50/60 Hz, 30 watts (CrossPoint 84, 88,

124, and 128) or 36 watts (CrossPoint 168 and 1616), auto-switchable power
supply of the CrossPoint Series provides worldwide power compatibility.

Rack Mounting the Switcher

The CrossPoint 84, 88, 124, and 128 Matrix Switchers are housed in rack-mountable,
3U high, 19” wide metal enclosures. The CrossPoint 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 128HVA.
The CrossPoint 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 1616HVA. The CrossPoint 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 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.

RGBHV video inputs — Connect RGBHV video inputs to these BNC

connectors for each output.

The CrossPoint 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 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)

CAUTION

The captive screw connector can easily be inadvertently plugged partially
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

4

3.5 mm, 5-pole captive screw connector for balanced or
unbalanced stereo audio input. Connectors are included
with each CrossPoint 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
impedance is generally over 800 ohms.

CrossPoint Matrix Switchers • Operation3-2

Figure 3-2 — Front Panel, CrossPoint 1616 HVA

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.

Current configuration — The configuration that is currently being used (also
called configuration 0).

Global memory preset — A configuration that has been stored. Up to
twelve global memory presets (CrossPoint 84, 88, 124, and 128) or sixteen
global memory presets (CrossPoint 168 and 1616) 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.

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

1

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.

Output 1 through 8 (16) buttons and LEDs — The output buttons and LEDs

2

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

3

configuration. To create a simple configuration, specify video, audio, or both
(see controls (7) and (8)); press the desired input button (1); press the desired
output button(s) (2); and press the Enter button.

Preset button and LED — The Preset button saves a configuration as a preset

4

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

5

allows the display of the current CrossPoint 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 is in view-only mode.

In view-only mode, pressing any input button (1) or output (2) 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 audio level (HVA
models only) on page 3-13.

Esc button and LED — The Esc button cancels operations or selections in

6

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.

3-3CrossPoint Matrix Switchers • Operation

Operation, cont’d

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 audio level (HVA models only)
on page 3-13.

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 (7)
and Audio (8) buttons.

RGBHV button and LED — The RGBHV button selects and deselects video

7

for a configuration being created or viewed. The RGBHV LED lights to
indicate that video is available for configuration or viewing.

Audio button and LED — The Audio button selects and deselects audio for a

8

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
pressing the View (5) and Esc (6) buttons. A more detailed explanation of
audio level adjustment is included in Viewing and adjusting the audio level (HVA

models only) on page 3-13.

Although present, the Audio button has no function on HV models.

Front panel I/O label windows

Input and output label windows — 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, Matrix Software, for
details on using the label software.

CrossPoint Matrix Switchers • Operation3-4

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 S
Hotline.

Creating a configuration

The current configuration can be changed using the front panel buttons. To change
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. Select to configure video, audio, or both by pressing the RGBHV and/or

Audio buttons.

3. Select the desired input and output(s) by pressing the input and output

buttons.

4. Press and release the Enter button.

5. 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

are disabled except for the view-only mode functions. See Viewing a configuration
on page 3-8. Other than in view-only mode, if the user pushes a front panel button
when the switcher is locked, that button’s associated LED flashes twice and goes

An input that produces an out-of-sync display, a display that is rolling

device is known to output non-TTL sync levels (greater than 5V p-p) should be
connected to one of the inputs with sync termination, and the termination
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, and it provides examples and descriptions for some
image problems you may encounter.

inputs 1, 3, 5, and 7. The switches provide a way to condition
non-TTL sync levels greater than 5 Vp-p, enabling the sync to be
properly passed from input to selected output(s). The
CrossPoints have two sets of sync termination switches; one for
horizontal or combined sync and a second set for vertical sync.

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.

CrossPoint Matrix Switchers • Operation3-16

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. Ensure an active input is selected for output on the switcher.

3. Ensure that the proper signal format is supplied.

4. Check the cabling and make corrections as necessary.

5. Call the Extron S

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. 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 3-21 and
use one for each preset configuration. The forms accommodate all of the
CrossPoint models. Cross off all unused or inactive inputs and outputs. Use
different colors for video and audio.

Worksheet example 1: Entering system equipment

Figure 3-19 shows a worksheet for a CrossPoint 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

The switcher’s rear panel RS-232/RS-422 connector (figure 4-1) can be connected to
the serial port output of a host device such as a computer, RS-232 capable PDA, or
control system. This connection makes software control of the switcher possible.

Figure 4-1 — RS-232/RS-422 connector pin arrangement

The CrossPoint Series Matrix Switchers are factory configured for RS-232
control. To use the switcher under RS-422 control, an internal cable must be
moved. Refer to appendix B for the procedure for moving the cable.

The RS-232/RS-422 connector on the CrossPoint 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 on page 3-16.

CrossPoint Matrix Switchers • Programmer’s Guide4-2

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.
Command and response examples are shown throughout the table.

Matrix Software

Two software programs accompany the CrossPoint Series switchers:

• The Extron Matrix Switchers Control Program (Extron part number 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 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 for details.

• The Extron Button-Label Generator, which allows you to design and print
labels for the CrossPoint 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).

This chapter describes both programs.

Matrix Switcher+ 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 disks to the hard drive, run SETUP.EXE
from the floppy disk and follow the instructions that appear on the screen. The
program occupies approximately 3 MB (megabyte) of hard-drive space.

By default, the Windows installation creates a C:\MTRX50 directory, and it places
two icons (Matrix Switcher+ Control Program and Matrix Switcher+ Help) into a
group or folder named “Extron Electronics”.

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 for
details.

1. To run the Matrix Switcher+ Control Program, double-click on the Matrix

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 5-4.

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 Follow box at the bottom of the window. To set up
audio in breakaway mode (audio and video have different tie configurations),
deselect the Follow box.

The program was designed to control most Extron matrix switchers, but its
operation is limited to the features and configuration of your
CrossPoint Series switcher.

8. If the switcher was removed from a rack, remove its power cord, reattach the

switcher to the rack, and reconnect the power cord.

9. Reconnect the input and output cables.

Installing a firmware update

The IC that contains the firmware for the matrix switcher also contains the
memory in which presets and audio levels are saved. When you replace the IC,
these settings will be lost. You may want to record the presets and audio levels
before you replace the IC.

To replace the firmware, do the following:

1. Follow the appropriate instructions in Opening the Switcher on page B-2 to gain

access to the interior of your switcher, including the instructions for removing
the front panel.

2. Locate the RS-232/RS-422 ribbon cable that connects the front panel board to

the rear panel RS-232/422 port (figure B-3). Note which receptacle on the
front panel board that the RS-232/RS-422 cable plugs into, and remove the
cable from its receptacle (see step 4 in Swapping the serial ports).

Do not touch the components inside the switcher without being electrically
grounded. Electrostatic discharge (ESD) can damage ICs, even if you cannot
feel, see, or hear it.

3. Unplug the power cable from the front panel board.

4. Place the front panel board, button side down, on a suitable workspace.

5. Locate IC U7 (figure B-3).

6. Use the PLCC IC puller to remove the existing firmware IC. Squeeze the tool

to align its hooks with the slots in opposite corners of socket U7.

Insert the hooks, squeeze gently, and pull the IC straight out of the

socket. Set the IC aside.

7. Note the key (angled corner) of the new firmware IC and

the dot on the underside that indicates pin 1 (figure B-4).
Orient the IC to match the key and pin 1 (indicated by
arrow) on the socket, and carefully press the IC in place.
