Intr Intr oduction, cont’d oduction 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. If a specif

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. Refer to each product’s user manual to determine the ranges for t

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

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. TP outputs — These switchers output 8 sets of TP signals for use by Extr

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 simultane

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. I/O grouping allows specific outputs, such as those for a specific family of twisted pair receivers, with a specific signal

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). Figure 2-1 — Rack mo
