TPX 88 Matrix Switchers • Introduction
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 control panel.
About the TPX 88 A Switchers
Local audio outputs have volume and mute controls. The switcher’s local audio
outputs are on 5-pole, 3.5 mm captive screw connectors. These local outputs follow
the RJ-45 outputs. For example, if audio input 6 is tied to audio output 1, then the
TPX’s local audio output 1 is the input 6 audio. This is true regardless of whether
the audio follows the video or is broken away from the video in the routing of
signals between twisted pair transmitters and receivers.
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 connectors.
The audio distributed by certain VersaTools
®
MTP transmitter/receiver pairs is
incompatible
with the audio extraction and processing capabilities of the
TPX 88 A.
The TPX 88 and the TPX 88 A cannot switch the audio that is distributed by
MTP RGB transmitters and receivers.
The TPX 88 can switch the audio that is distributed by MTP S-video and
composite video
transmitters and receivers.
The TPX 88 A can switch the audio that is distributed by MTP S-video and
composite video
transmitters and receivers but cannot extract it for the
local connectors.
On the TPX 88 A, the switching of the audio portion of the TP link can either be
linked with the video portion (audio follow) or independent of the video portion
(audio breakaway).
