Setup Guide ­— TPX 88 series (cont’d)
• Connect a serial port controller. Wire the
connector as shown in the table at right.
About Audio
• Use the RS-232/RS-422 DIP switches to
configure the port for the desired protocol.
The TPX 88 A has local audio outputs on 5-pole,
3.5 mm captive screw connectors. These outputs
always follow the RJ-45 outputs, regardless of
whether the audio follows the video or is broken
away from the video in the TP ties.
The TP transmitters and receivers distribute audio in a proprietary digital channel of
the TP link.
• The TPX 88 cannot switch this audio.
• The TPX 88 A can switch this audio and extract it for the local audio connectors.
N
The audio distributed by MTP transmitter and receivers is incompatible with the
audio extraction and processing capabilities of the TPX 88 A.

power connector and a 100 VAC to 240 VAC, 50
or 60 Hz power source.
Operation — Creating ties
A Tie is an input-to-output connection. An input can be tied to more than one outputs. An
output can never be tied to more than one input.
I/O
Create ties as follows:
VIDEO
AUDIO
1. TPX 88 A only — Press and release the I/O
button to select video and audio, video only,
or audio only.
• The TPX 88 and the TPX 88 A cannot switch the mono audio that is distributed
by most MTP transmitters and receivers.
• The TPX 88 and the TPX 88 A can switch the stereo audio that is distributed by
stereo audio versions of the MTP S-video and composite video transmitters and
receivers, but the TPX 88 A cannot extract it for the local connectors.
