Defining the audio/RS-232 wire pair
N 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 3-46.
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

RS-232 settings can be viewed and changed from the front panel.
