Quick Start — TPX Matrix Switchers

Installation

Step 1 — Turn off power Step 2

Cable the switcher for twisted pair input and output. See Termination of TP cable in chapter 2, Installation, to properly terminate the RJ-45 connectors.

Step 4

If desired, connect a control system or computer to the Remote (RS-232/RS-422) port.

*The TPX 88 A switches pair 3 and 6.

The TPX 88 does not switch pair 3 and 6.

Audio or serial data from an RGB video MTP is incompatible with both TPX models.

They cannot be switched.

Step 5

Set the rear panel Remote DIP switches.

RS-232All switches up

for RS-232. (Default.)

Switches 1 & 2 down,

RS-4223 up for RS-422.

Step 6

Plug the switcher and input and output devices into a grounded AC source, and turn on the input

NOTE If you are using Enhanced Skew-Free™ A/V cable, use the TIA/EIA T 568A standard only.

Definitions

Tie — An input-to-output connection.

Set of ties — An input tied to 2 or more outputs.

Configuration — One or more ties or sets of ties.

Current configuration — The currently active configuration (also called configuration 0).

Global preset — A configuration that has been stored. One preset can be assigned to each input button. When a preset is retrieved from memory, it becomes the current configuration.

Front Panel Controls

Input and output buttons and LEDs select and identify inputs and outputs. Input buttons also select presets. On the TPX 88 A, the input and output LEDs also display the audio
