Ab o u t t h e TPX 88 Ma n u a l  
This manual provides installation, operation, and maintenance information for the  
Extron TPX 88 and TPX 88 A matrix switchers. The TPX switchers are 8-input by  
8-output matrix switchers for routing the signals that Extron twisted pair (TP)  
transmitters and receivers use to distribute video and audio signals in an A/ V  
system.  
In this manual, the term “TPX 88” is generally used to identify both twisted pair  
matrix switchers. If a specific discussion relates to the audio version only, the term  
“TPX 88 A” is used.  
In this manual, the terms “twisted pair transmitter” and “twisted pair receiver”  
refer to any transmitter or receiver listed in the table on the following pages; the  
terms “TP transmitter” and “TP receiver” refer specifically to members of the TP  
family of Extron twisted pair transmitters and receivers, such as the TP T 15HD A  
and the TP R BNC A.  
Besides the TPX 88s video signal routing capabilities, the TPX 88 A can route the  
TP transmitter familys digital audio outputs, switching the audio with the video  
(audio follow) or separate from the video (audio breakaway). The TPX 88 A can  
also process the audio, adjusting the gain and attenuation, and output the audio  
locally on the switchers rear panel.  
Ab o u t t h e TP A/V Syst e m  
The Extron twisted pair transmitters, twisted pair receivers, and TP matrix  
switchers provide a system for long-distance distribution of video and stereo or  
mono audio over Extrons Enhanced Skew-Free™ A/ V unshielded twisted pair  
(UTP) cable or over Category (CAT) 5 UTP, shielded twisted pair (STP), or foil  
shielded twisted pair (FTP) cable. The table on the following page lists the Extron  
transmitters and receivers that are compatible with the TPX units and their video  
and audio capabilities. With adapters, many RGBHV twisted pair products can  
also distribute component, S-video and/ or composite video.  
TP ca b le a d va n t a g e s  
Extrons Enhanced Skew-Free A/ V UTP cable and CAT 5 cable are a fraction of the  
size of coaxial cable, as well as being much lighter, more flexible, and far less  
expensive. These TP products make cable runs simpler and less cumbersome.  
Termination of the cable with RJ-45 connectors is simple, quick, and economical.

MTP transmits or receives audio, but the TPX 88 and TPX 88 A cannot switch this TP device's audio.  
The TPX 88 and TPX 88 A switch the audio but cannot process it or output it locally.  
Video and audio capabilities are dependent on the MTP transmitter providing the input.  
The TPX 88 does not support the TP R receivers' automatic level and peaking feature or the input signal  
detect feature (the receiver's power LED lights amber only). Support of the automatic level and peaking  
and the signal detect features, requires the use of a TPX 88 A.

The minimum reliable transmission distance between transmitters and receivers is  
50 feet for most models. The maximum distance is determined by the output  
frequency, resolution, and the transmitter/ receiver family. The table below lists the  
recommended maximum transmission distances for most transmitter/ receiver  
families using Extron Enhanced Skew-Free A/ V UTP cable, terminated with CAT 5  
rated connectors.  
Refer to each products user manual to determine the ranges for that family of  
products.

It is possible to exceed the recommended distances, however, image quality may  
be reduced.  
Extron recommends using the highest quality cable available and affordable,  
with less than 8 nanoseconds/100 meters of skew (see Termination of TP  
cable in chapter 2). We also recommend the use of pre-terminated and tested  
cables. Cables terminated on site should be tested before use to ensure that  
they comply with Category 5 specifications.  
Extron Skew-Free A/V UTP cable is recommended for most applications.  
CAT 5 cable can be satisfactorily used for some products (refer to each  
products user manual). The system can be used with cable other than that  
recommended, but video performance will be compromised and maximum  
cable lengths and video resolutions must be decreased.

The TPX switchers are single box solutions to simple twisted pair routing  
applications (figure 1-1). 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 TPX 88 switchers support I/ O grouping, a feature that lets you virtually divide  
the matrix into up to four smaller sub-switchers, making installation and control  
easier. I/ O grouping allows you to separate different signal types to avoid  
connecting signal types from different, incompatible, transmitter/ receiver families.  
The TPX matrix switchers are housed in rack-mountable, 1U high, 17" wide metal  
enclosures. The appropriate rack mounting kit is included with each switcher,  
allowing you to mount the switcher in a standard 19" rack. Each model has an  
internal 100 VAC to 240 VAC, 50/ 60 Hz, 25 watts, auto-switchable, power supply  
that provides worldwide power compatibility.  
Many twisted pair transmitters and receivers have the ability for one  
component of the pair to provide power for the other (such as a TP R BNC A  
providing the power for a TPT BNC).  
The TPX 88 cannot power connected twisted pair transmitters and receivers.  
The TPX 88 cannot switch the power that a twisted pair transmitter or  
receiver supplies to a twisted pair receiver or transmitter.  
In a twisted pair system that includes a TPX 88, both the twisted pair  
transmitter and the twisted pair receiver must be powered locally. The  
appropriate power supply is included with the transmitters and receivers.

The TPX switcher can be remotely controlled via its Remote (RS-232/ RS-422) port.  
The switchers are programmed with Extrons Simple Instruction Set(SIS), a set  
of basic ASCII code commands that provide simple control through a third party  
control system or PC without programming long, obscure strings of code.  
The Remote port can be connected to a control system, a PC, or an Extron  
MCP 1000 remote control panel and/ or MKP 1000 remote keypad, MKP 2000  
remote control panel, or MKP 3000 remote control panel.  
Ab o u t t h e TPX 88 A Sw it ch e rs  
Local audio outputs have volume and mute controls. The switchers local audio  
outputs are on 5-pole, 3.5 mm captive screw connectors. These local outputs follow  
the RJ-45 outputs. For example, if audio input 6 is tied to audio output 1, then the  
TPX’s local audio output 1 is the input 6 audio. This is true regardless of whether  
the audio follows the video or is broken away from the video in the routing of  
signals between twisted pair transmitters and receivers.  
The TP transmitters and receivers distribute audio in a proprietary digital  
channel of the TP link.  
The TPX 88 cannot switch this audio.  
The TPX 88 A can switch this audio and extract it for the local connectors.  
The audio distributed by certain VersaTools® MTP transmitter/receiver pairs is  
incompatible with the audio extraction and processing capabilities of the  
TPX 88 A.  
The TPX 88 and the TPX 88 A cannot switch the audio that is distributed by  
MTP RGB transmitters and receivers.  
The TPX 88 can switch the audio that is distributed by MTP S-video and  
composite video transmitters and receivers.  
The TPX 88 A can switch the audio that is distributed by MTP S-video and  
composite video transmitters and receivers but cannot extract it for the  
local connectors.  
On the TPX 88 A, the switching of the audio portion of the TP link can either be  
linked with the video portion (audio follow) or independent of the video portion  
(audio breakaway).

Fe a t u re s  
Inputs — These switchers accept 8 sets of TP signals that are input from Extron  
twisted pair transmitters on TP cable terminated with RJ-45 connectors. Each  
transmitter creates the proprietary signal from its RGBHV, RGBS, RGsB,  
RsGsBs, HDTV, component video, S-video, or composite video input. Most  
transmitters also include either digital or differential analog audio on the  
proprietary signal.  
TP outputs — These switchers output 8 sets of TP signals for use by Extron twisted  
pair receivers.  
TPX 88 — The output proprietary signal includes the encoded video  
(RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or  
composite video), but not the audio output by most TP transmitters.  
However, if the input TP link originated from an MTP transmitter with audio,  
the output proprietary signal also includes the audio portion of the link.  
TPX 88 A — The output proprietary signal includes the encoded video  
(RGBHV, RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or  
composite video) and audio.  
Audio outputs (TPX 88 A only) — If the input TP link originated from a member of  
the TP family of transmitters (see the table on page 1-3 and page 1-4), the  
TPX 88 A outputs 8 stereo audio outputs, balanced or unbalanced, on 3.5 mm,  
5-pole captive screw terminals.  
Audio gain and attenuation (TPX 88 A only) — Users can set the input level of  
audio gain or attenuation (-18 dB to +24 dB) for the signal that is output  
locally. Gain and attenuation can be set 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).

Audio output volume (TPX 88 A only) — The audio level of each local output can  
be adjusted through a range of 100% (no attenuation) to 0% (full attenuation).  
The audio level can be adjusted under front panel or RS-232/ RS-422 control.  
Switching flexibility — Provides individually buffered, independent matrix  
switched outputs with audio follow and audio breakaway for the TPX 88 A.  
Any input to any or all outputs  
Quick multiple tie — Multiple inputs can be switched to multiple outputs  
simultaneously. This allows all displays (outputs) to change from source to  
source at the same time.  
Audio follow (TPX 88 A) — The audio portion of the TP link input can be  
switched with the corresponding video portion of the input TP link. 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 (TPX 88 A) — The audio portion of the TP link input can  
be broken away from its corresponding video portion of the input TP link.  
Audio breakaway switching can be done via front panel control or under  
RS-232/ RS-422 remote control.  
Audio from a transmitter in the MTP family cannot be broken away.  
Operational flexibility — Operations such as input/ output selection, setting of  
presets, and adjustment of audio output levels (TPX 88 A only) 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 or control system.  
Front Panel Controller — The TPX front panel controller feature supports  
touch-of-a-button input and output selection, preset creation and selection,  
and (TPX 88 A only) audio output volume control. The front panel features  
large, positive touch, illuminated input and output pushbuttons that can be  
labeled with text or graphics.  
Windows-based control program — For RS-232/ RS-422 remote control from  
a PC, Extron includes its Windows-based control software with every matrix  
switcher. The 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 Extrons  
SIS for easy programming and operation.  
Remote control — The matrix switchers are remote controllable, using the  
MCP 1000 master control panel 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 — Extrons label software ships with every Extron matrix switcher. You  
can create labels to place in the front panel I/ O 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.

Global memory presets — 16 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.  
I/O grouping — Allows the matrix to be virtually divided into up to four smaller  
sub-switchers, making installation and control easier. I/ O grouping allows  
specific outputs, such as those for a specific family of twisted pair receivers,  
with a specific signal format, to be grouped together. Switching between I/ O  
groups is not possible from the front panel.  
Rack mount — Rack mountable in any conventional 19" wide rack.  
Front panel security lockout (executive mode) — If a TPX 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.  
Power supply — Includes an internal 100 VAC to 240 VAC, 50/ 60 Hz, 25 watts  
auto-switchable power supply, which provides worldwide power  
compatibility.

Enhanced Skew-free A/V cable is not recommended for Ethernet/LAN  
applications.  
This cable is specially designed for compatibility with Extrons Twisted Pair  
products that are wired using the TIA/EIA 568 A standard.  
The green, brown, and blue pairs of this cable have virtually identical lengths  
and should be used to transmit the RGB signals.  
The orange pair of this cable has a different length and should not be used to  
transmit the RGB signals.  
You can use either wiring standard, but ensure that you use the same  
standard on both ends of both cables; the cable from the transmitter and the  
cable from the receiver.  
Ensure that you terminate the RJ-45 connectors for each cable properly for the  
family (TP, VTT, MTP) of transmitter or receiver connected.  
On RGB video MTPs, the audio or serial data that is carried on wire pairs 3  
and 6 is incompatible with the TPX 88 A. The TPX 88 A cannot switch the  
audio or serial data, output the audio locally, or break the audio away.  
The TPX 88 does not switch or process wire pair 3 and 6.  
Most TP transmitter/ receiver audio (audio that is associated with the  
RGBHV link) is carried on wire pair 3 and 6, so the TPX 88 cannot switch  
°
this audio.  
On S-video and composite video MTPs, audio is carried on wire pairs  
other than pair 3 and 6, so the TPX 88 switches this audio. The TPX 88  
cannot output the audio locally or break it away.  
°
The TPX 88 A switches and processes wire pair 3 and 6.  
The TPX 88 A switches and processes the proprietary digital audio link

Ca b le t e st in g  
Systems that use Extrons skew-free UTP cable do not need to be tested for  
skew.  
To ensure proper cable termination, each transmission cable system that uses CAT 5  
cable should be tested. Testing the cable between the RJ-45 connections at the  
transmitter and TPX 88 (transmitter cable system) and between the TPX 88 and the  
receiver (receiver cable system) gives the most accurate indications of cable  
problems.  
There are two varieties of cable runs: simple runs, in which a single cable is  
terminated only at the transmitter, TPX 88, and receiver, and complex runs, which  
can include patch bays and multiple terminations and lengths of cable. In either  
case, the entire transmitter cabling system and receiver cabling system should be  
tested.  
A complete test measures cable length and tests the wire map, attenuation, NEXT,  
PSNEXT, ELFEXT, PSELFEXT, return loss, ACR and PSACR. All of these tests are  
critical for digital data transfer, but not for analog video. While all of these tests are  
important indicators of the quality of the cable termination, the most critical testing  
parameters for video transfer are wire map (T-568-A or T-568-B termination) and  
pair length measurements. The largest concern is equalization of skew between  
cable pairs. Cable systems of 300 feet (91 meters) or less should exhibit no  
transmission problems if they pass at least CAT 5e or preferably CAT 6-D5 channel  
certification testing.

The Microtest OMNI SCANNER 2 performs comprehensive certification testing to  
the proposed CAT 6 standards. Other manufacturers also make testing equipment.  
The tests include advanced diagnostics for troubleshooting the cause and location  
of many cable and termination problems. For simple installation testing, the  
Microtest MICRO SCANNER PRO tests wire map and cable length, including  
individual cable pair length.  
The manufacturing process for network (CAT 5) UTP cable leads to a condition  
called pair skew. Skew exists between pairs when the physical length of one wire  
pair is different from another. As the transmission cable length increases, the  
amount of skew increases. Skew affects the displayed image when the differential  
length between wire pairs exceeds 2 feet, causing the timing of the red, green, and  
blue video signals to appear out of alignment (horizontal registration errors). A  
white vertical line on a black field can appear as individual red, green, and blue  
lines that are close together; the signal transmitted on the shortest wire pair leads  
the other colors and appears to the left on the display.  
Pair skew can be measured with test equipment. UTP cable test equipment  
measures and reports wire pair length. In certain circumstances, the report on the  
various pair lengths can be used in equalizing pair skew.  
If test equipment is not available, skew can be identified by viewing a crosshatch  
test pattern with a critical eye to determine if either the red, green, or blue video  
image leads (appears to the left of) the other two video images.  
For best results when using CAT 5 cable in A/ V applications, pair skew needs to be  
equalized. Extron suggests several ways to equalized the pair skew as follows.  
The design of Extrons Skew-Free A/V UTP cable minimizes pair skew to the  
point that equalization is not required.  
If there are different cable types and/or big differences in input cable length,  
skew compensation will not work.  
Eq u a lizin g p a ir ske w w it h Ske w Eq u a lize rs  
Try using the following methods to minimize or eliminate pair skew:  
If using MTP 15HD (RGB video) receivers, switch to SEQ versions of the  
receivers.  
Install separate SEQ 100 15HD or SEQ 100 BNC Skew Equalizers on the  
receivers’ video outputs and adjust the skew for the leading video image.  
Eq u a lizin g p a ir ske w w it h ske w co m p e n sa t io n ca b le s  
The nominal velocity of propagation (NVP — the speed at which the signal travels  
on the transmission line, measured as a percentage of the speed of light) of TP cable  
is very close to that of conventional coaxial cable. The similarity in NVP means  
that, when all transmitter cables systems use the same cable type and are  
approximately equal in length, by adding an additional length of coax, equal to the  
length of pair skew, placed on the receivers output, you can equalize the effects of  
pair skew (figure 2-4).  
If UTP cable test measurement cannot be done, pair skew can still be equalized,  
assuming that all of the transmitter cable systems are equal, by viewing a  
crosshatch test pattern with a critical eye. Examine the test pattern for loss of  
horizontal registration and, through a process of trial and error, equalize any pair  
skew with coax extensions on the red, green, and/ or blue outputs.  
Extron skew compensation coax cables are available in lengths of 2 through 20 feet,  
see Appendix A for part numbers.

The following terms, which apply to Extron matrix switchers, 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 — Consists of one or more ties 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 sixteen  
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.  
In p u t a n d o u t p u t b u t t o n s  
The large, illuminated input and output pushbuttons can be labeled with text and/  
or graphics. The buttons can be set to provide amber background illumination all  
the time or the background illumination can be set off. The buttons blink or are  
fully illuminated (depending on the operation) when selected.  
Input 1 through 8 buttons — The input buttons have three independent  
functions: to select an input, to identify the selected inputs, and to select a  
preset. A more detailed explanation of these functions is included in  
Operations, beginning on page 3-5.

all of the unassigned outputs. No input button is lit.  
Esc button — The Esc button cancels operations or selections in progress and  
resets the front panel button indicators. The Esc button does not reset the  
current configuration or any presets. On the TPX 88 A, the Esc button does  
not reset the video and/ or audio selection or any audio gain or attenuation  
settings.

The following paragraphs detail the power up process and 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.  
Po w e r  
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 cycles the front  
panel I/ O button indicators on and off from left to right lit green, right to left lit  
red, and left to right lit amber. An error-free power up self-test sequence leaves the  
Video and/ or the Audio LEDs on (TPX 88 A only), all other LEDs unlit, and all I/ O  
buttons either unlit or showing background illumination.  
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 is an RS-232/ RS-422 controlled feature that allows you to subdivide  
the front panel control of the matrix into up to four smaller functional sub-  
switchers. Inputs and outputs can be assigned to one of four groups (figure 3-4) or  
not assigned to any group. 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.

The I/ O groups can be set up only by using the RS-232/ RS-422 port and either the  
SIS or the Windows control program (see chapter 4, Programmers Guide, and  
chapter 5, Matrix Software. Ties between groups (an input in group 1 tied to an  
output in group 2) can be created under RS-232/ RS-422 control. Presets can also be  
created under RS-232/ RS-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 twisted pair transmitter and receiver formats to prevent  
a transmission from one family of twisted pair transmitters from being  
inadvertently applied to a twisted pair receiver from an incompatible family.  
See the table on page 1-3 and page 1-4 for twisted pair transmitter and  
receiver compatibility.  
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/ RS-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 where applicable.

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 buttons, output buttons, or control  
buttons that may be lit.  
2.  
(TPX 88 A only) Select to configure video, audio, or both by pressing the I/ O  
button. The Video and/ or Audio LEDs light to indicate that video and/ or  
audio are selected.  
3.  
Select the desired input and output(s) by pressing the input and output  
buttons.  
Input and output buttons light amber to indicated video and audio ties. The  
buttons light green to indicated video only ties. The buttons light red to  
indicate audio only ties.  
To indicate current ties, the buttons for tied outputs light the appropriate color  
(amber, green, or red) when an input is selected. To clear unwanted outputs  
press and release the associated lit 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.  
Only one video input and one audio input can be tied to an output but  
multiple outputs can be tied to a single input.  
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.  
If an input with no tie is selected, only that inputs button lights. The  
button lights the appropriate color for the video and/or audio selection.  
When the Video and Audio LEDs are lit, if an input with an audio tie but  
no video tie is selected, the inputs button lights amber and the output  
button lights red.  
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  
button does not light. That output cannot be tied to an input from a  
different group using the front panel. The associated input button  
remains lit.

The current configuration (configuration 0) can be saved as a preset in any one of  
16 preset memory addresses, or, as many presets as the switcher has input and  
output buttons.  
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.  
Presets cannot be viewed from the front panel unless recalled as the  
current configuration. Presets can be viewed using Extrons Windows-  
based control program. See Chapter 5, Matrix Software, for more details.  
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.  
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.

illuminated input button indicates approximately 7 dB of volume attenuation  
(whether there is an input associated with the button or not). There are eight  
steps displayed, from full attenuation applied (no input buttons lit, or 50 dB  
of attenuation) to the full volume output (all input buttons lit, or output  
volume equal to the input signal plus any gain or attenuation).  
Another way to view the volume level is to realize that each lit input button  
indicates up to 14 percent of the input volume is applied to the output. When  
all 8 input buttons are lit, the switcher is outputting 100% of the audio input.

Tro u b le sh o o t in g  
This section gives recommendations on what to do if you have problems operating  
the TPX switcher.  
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.  
Wo rksh e e t s  
Rather than trying to remember the configuration for each preset, use worksheets  
to record this information. Make copies of the blank worksheet on page 3-31 and  
use one for each preset configuration. Cross out all unused or inactive inputs and  
outputs. If applicable, use different colors for video and audio.  
Wo rksh e e t e xa m p le 1: Syst e m e q u ip m e n t  
Figure 3-47 shows a worksheet for a TPX 88 A in a fictional organization. System  
hardware is annotated. Input 6 has no connection, so it has been crossed out.  
Inputs include PCs, a CD player, cameras, and a VTG 300, all connected through TP  
transmitters. Output devices include monitors, front and rear projectors, a stereo,  
and a VCR for recording presentations, all connected through TP receivers.  
The Extron VTG 300 video test generator connected to input 8 enables a video test  
pattern to be sent to one, several, or all output devices for problem isolation or  
adjustment purposes. An audio test tape or CD could be used in a similar manner  
to check out the audio components.

Figure 3-48 continues from worksheet example 1 by showing the video and audio  
ties that make up the configuration of preset 1; a solid ink line shows video ties and  
a dashed pencil line shows the audio ties. In this example, the image of the  
presenter, from the main podium camera (input 1), is displayed in the main hall  
(output 1), to the overflow crowd in the conference room (output 4), and in the  
lobby (output 8). The image is also tied to the VCR (output 6). The presenter has a  
presentation on her laptop computer (input 4) that is scan converted and displayed  
in the main hall (output 2) and locally on the podium (output 3). The audio from  
her microphone (input 3) is played in the hall (output 1), in the conference room  
(output 4), and sent to the VCR. Classical music from the CD player (input 5) is  
being played in the background in the main hall on sound system #2 (output 5),  
and in the lobby (output 8).

The A/ V system in our fictional organization needs to be fine tuned on a regular  
basis. Figure 3-49 shows a typical test configuration, with an Extron video test  
generator (input 8) generating a test pattern to all monitors (outputs 1, 2, 3, 4, and  
8). Sound checks are run from the CD player (input 5) to all audio systems (outputs  
1, 2, 4, 5, and 8).

The switchers rear panel 3.5 mm, 5-pole captive screw connector (figure 4-1) can  
be connected to the RS-232 or RS-422 serial port output of a host device such as a  
computer running the HyperTerminal utility, an RS-232 capable PDA, or a control  
system. This connection makes software control of the switcher possible.

Fig u re 4-1 — Re m o t e co n n e ct o r p in a rra n g e m e n t  
The TPX switcher can communicate using either the RS-232 or RS-422 serial  
communication protocol. The protocol is DIP-switch selectable. See chapter 2,  
Installation, to configure the DIP switches.  
The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.  
Ho st -t o -Sw it ch e r In st ru ct io n s  
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.  
Sw it ch e r-In it ia t e d Me ssa g e s  
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 2003, Extron Electronics, TPX 88, Vx.xx  
The switcher initiates the copyright message when it is first powered on. Vx.xx is  
the firmware version number.  
Qik  
The switcher initiates the Qik message when a front panel switching operation has  
occurred.  
Rprnn  
The switcher initiates the Rpr message when a memory preset has been recalled  
from the front panel. nn” is the preset number.  
Sprnn  
The switcher initiates the Spr message when a memory preset has been saved from  
the front panel. nn” is the preset number.  
Innn Audxx  
The switcher initiates the Aud message when a front panel audio level operation  
has occurred. nn” is the input number and “xx” is the dB level.

Outnn Volxx  
The switcher initiates the Aud message when a front panel audio volume level  
operation has occurred. nn” is the output number and “xx” is the volume level.  
Exen  
The switcher initiates the Exe message when executive mode is toggled on or off  
from the front panel. n” is the executive mode status: 1 = on, 0 = off.  
Amtn  
The switcher initiates the Amt message when audio mute is toggled on or off for all  
local audio outputs from the front panel. n” is the mute status: 1 = on (muted),  
0 = off (unmuted).  
Sw it ch e r Erro r Re sp o n se s  
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)

Two software programs accompany the TPX 88 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.  
The TPX switcher can communicate using either the RS-232 or RS-422 serial  
communication protocol. The protocol is DIP-switch selectable. See chapter 2,  
Installation, to configure the DIP switches.  
The Extron Button-Label Generator, which allows you to design and print  
labels for the TPX switchers 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).

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:\ MTRX50 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 TPX switcher.  
Usin g t h e so ft w a re  
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 5-7  
for details.  
1.  
To run the Matrix Switcher+ Control Program, double-click on the Matrix  
Switcher+ Control Program icon (shown at left) in the  
Extron Electronics group or folder.  
2.  
3.  
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 5-7.  
The Extron Matrix Switcher+ Control Program window (figure 5-1 and  
figure 5-2) displays the current configuration of the attached matrix.  
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.
