Defining the Audio/RS-232 wire pair
N The audio/RS-232 TP input settings (RS-232 or audio) are protected when front
panel Lock mode 2 is selected. You can view the settings in Lock mode 2 but
you cannot change them from the front panel. See “Setting the front panel locks
(
Executive modes)” on page 3-40.
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. Each TP input’s audio/
RS-232 settings can be viewed and changed from the front panel.
