Extron electronic TPX 88 A Cabling and Rear Panel Views, TPX 88 Matrix Switchers Installation

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.

The rear panel of the TPX 88 has most of the same features as the TPX 88 A, but without the local audio connectors.

CAUTION

Do not connect this device to a computer data or telecommunications network

RJ-45 termination must comply with the TIA/EIA T 568A or TIA/EIA T 568B wiring standards for all connections.

1Inputs connectors — Connect one end of a TP cable to each of these RJ-45 female connectors. Connect the other end of each cable to a compatible twisted pair transmitter. See Termination of TP cable in this chapter.

2Outputs connectors — Connect one end of a TP cable to each of these RJ-45 female connectors. Connect the other end of each cable to a compatible twisted pair receiver. See Termination of TP cable in this chapter.

Extron skew-free A/V cable is recommended for all applications.

CAT 5 and CAT 6 cable can be used for TP and VTT transmitters and receivers.

CAT 6 cable is not recommended for MTP transmitters and receivers.

The TP R receivers’ automatic level and peaking and signal detect features require the use of a TPX 88 A.

To support TP R receivers’ level and peaking features, either the automatic or manual adjustment, use TP cables of approximately the same length on all TP inputs ( 1 ) and on all TP outputs ( 2 ).

3Audio Outputs connectors (TPX 88 A only) — These 3.5 mm, 5-pole captive screw connectors output unamplified, unbalanced or balanced line level audio. The local audio outputs follow the RJ-45 outputs; that is, if input 6 is tied to output 1, then audio output 1 is the input 6 audio. See Audio outputs connectors (TPX 88 A only) in this chapter.

These audio outputs are not available if the TP input is from an MTP family transmitter.

4Remote connector — Connect a host device to the TPX 88 via this 3.5 mm,

5-pole captive screw connector for serial RS-232/RS-422 control. See Remote port configuration in this chapter.
