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)” on page 59).
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 and Audio/RS-232 Input Configuration mode: Simultaneously
press and hold all Control buttons (Enter, Preset, View, and Esc).
