2-3TPX 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.
1
Inputs 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.
2
Outputs 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
).

Audio 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.
4
Remote 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.
