TPX 88 Twisted Pair Matrix Switchers 1 Chapter One Introduction About the TPX 88 Manual About the TP A/V System About Both TPX Switcher Models About the TPX 88 A Switchers Features
Introduction, cont’d Introduction About the TPX 88 Manual 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.

Transmission distances 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.
Introduction, cont’d About Both TPX Switcher Models 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 switcher can be remotely controlled via its Remote (RS-232/RS-422) port. The switchers are programmed with Extron’s 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.
Introduction, cont’d Features 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.
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.
Introduction, cont’d 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.
TPX 88 Twisted Pair Matrix Switchers 2 Chapter Two Installation Mounting the Switcher Cabling and Rear Panel Views
Installation, cont’d Installation Mounting the Switcher The TPX switchers are housed in rack-mountable, 1U high, 17" wide metal enclosures. The appropriate rack mount kit is included with the switchers, allowing you to mount the switcher in a standard 19" rack. Rack mount the switcher as follows: 1. If rubber feet were installed on the bottom of the switcher, remove them. 2. Attach the rack mount brackets to the switcher with eight #8 machine screws, provided (figure 2-1).
Cabling and Rear Panel Views All connectors are on the rear panel. The switcher can connect to as many as eight compatible twisted pair transmitters for input and twisted pair receivers for output. The TPX 88 A has output connections for eight local audio outputs. See the tables on page 1-3 and page 1-4 for audio compatibility. Figure 2-2 shows the rear panel of a TPX 88 A twisted pair matrix switcher.
Installation, cont’d 5 6 Remote configuration DIP switches — Set these DIP switches to select either RS-232 or RS-422 serial control protocol. Set DIP switches 1 and 2 both down for RS-422 or set switches 1 and 2 both up for RS-232. DIP switch 3 should always be up. See Remote port configuration in this chapter. RS-232 RS-422 AC power connector — Plug a standard IEC power cord into this connector to connect the switcher to a 100 VAC to 240 VAC, 50 or 60 Hz power source.
Enhanced Skew-free A/V cable is not recommended for Ethernet/LAN applications. This cable is specially designed for compatibility with Extron’s 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.
Installation, cont’d 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.

TPX 88 Twisted Pair Matrix Switchers 3 Chapter Three Operation Front Panel Controls and Indicators Operations Troubleshooting Worksheets
Operation, cont’d Operation Front Panel Controls and Indicators The front panel controls (figure 3-1) are grouped into four sets. The input and output buttons are grouped on the left side of the control panel. The control buttons are grouped in the middle of the panel. On the TPX 88 A only, the input/ output (I/O) selection button and audio controls are grouped on the right side of the panel. The TPX 88 is identical to the TPX 88 A, with the exception that it does not have I/O selection or audio controls.
Control buttons 3 Preset button and LED — The Preset button saves a configuration as a preset, or recalls and makes active a previously-defined preset. The Preset LED indicates save mode when it is blinking and recall mode when it lights steadily. 4 Enter button — The Enter button saves changes when you set up a new configuration.
Operation, cont’d I/O controls (TPX 88 A only) When creating or viewing a configuration, you must specify whether the configuration applies to video, audio, or both. This is done with the I/O selection button ( 7* ) and indicated by the Video and Audio ( 8* ) LEDs. 7* I/O button — The I/O button selects video, audio, or video and audio for input selection.
Button icons The numbered translucent covers on the pushbuttons can be removed and replaced to insert labels behind the covers. Input and output inserts can be created easily with Extron’s Button Label Generator software, which ships with every Extron matrix switcher. 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 shows a sample set of button inserts in a typical configuration.
Operation, cont’d I/O grouping 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 subswitchers. 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.
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. Creating a configuration The current configuration can be changed using the front panel buttons. To change the current configuration, do the following: 1.
Operation, cont’d Example 1: Creating a set of video and audio ties The following steps show an example in which input 5 is tied to outputs 3, 4, and 8. Where an explanation is helpful, the steps show the front panel indications that result from your action. This example assumes that there are no ties in the current configuration. 1. Press and release the Esc button. 2. TPX 88 A only — To select video and audio for the tie, if necessary, press and release the I/O button until the LEDs light (figure 3-5).

TPX 88 Twisted Pair Matrix Switchers 5 Chapter Five Matrix Software Matrix Switchers Control Program Button-Label Generator
Matrix Software, cont’d Matrix Software 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.
Figure 5-1 — Extron Matrix Switcher+ Control Program window (blank) 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.
Matrix Software, cont’d Firmware upgrade The Matrix Switcher+ control program provides a way to replace the firmware that is coded on the switcher’s control board. Perform a firmware upgrade as follows: 1. Visit the Extron web site, www.extron.com, select the TPX product category, and select the latest firmware file for download. Note the folder to which you save the firmware file. 2. Connect the PC to the TPX switcher via the switcher’s RS-232/RS-422 port. 3.
Windows buttons, drop boxes, and trash The buttons, drop boxes, and trash can on the right side of the program window perform the following functions: Power — Unavailable for TPX switchers, because the switcher power cannot be controlled via software. Executive mode — Allows you to lock out front panel operations, except for the view-only mode functions. Presets menu — Displays a list of up to 16 global presets .
Matrix Software, cont’d Mute-Output settings — Displays the audio output level setting for a single input or for all inputs and allows you to change it. The level is expressed as a percentage of the input audio volume that is applied to the output; 0% is full attenuation (audio is silent), 100% is full volume. Update firmware — Allows you to upload replacement firmware files to upgrade the switcher ’s operating system. See Firmware upgrade, in this chapter.
Limit ties to same group — Allows you to limit the creation of ties using the program to within the same group (similar to front panel operation). Icons in I/O boxes — Erases any numbers in the I/O boxes in the ties-as-lines window (figure 5-2). You can place icons in the boxes. Numbers in I/O boxes — Erases any icons in the I/O boxes in the ties-as-lines window and fills each box with the associated input or output number.
Matrix Software, cont’d Button-Label Generator The program is contained on the same set of 3.5-inch diskettes as the Matrix Switcher+ Control Program and is installed automatically when you install that program. By default, the Windows installation goes in either the C:\MTRX50 directory if it is installed automatically with the Matrix Switcher+ Control Program or the C:\BUTTONS directory if it is installed as a stand-alone program.
