Extron Electronics MTPX Plus 6400 Series User Guide - Manual (Page 61)

Defining the Audio/RS-232 Wire Pair
NOTE: The TP audio/RS-232 input wire pair configurations are protected when front
panel Lock mode 2 is selected. You can view the configurations in Lock mode 2
but you cannot adjust them from the front panel (see “
Setting the Front Panel
Locks (Executive Modes) ” ).
The switcher is compatible with MTPs that transmit and receive mono audio and those that
transmit and receive RS-232 serial data. You must configure the switcher for the appropriate
audio/RS-232 input for each TP input. The audio/RS-232 settings for each TP input can be
viewed and changed from the front panel.
View and configure the TP input audio/RS-232 configuration settings for the switcher as follows:
1. Select Serial Port Selection and Configuration mode: Simultaneously
press and hold all Control buttons (Enter, Preset, View, and Esc).
