Setting BUS-EN
The output configuration is taken from the non-volatile memory.
• SW1-1 ON connects the outputs to the audio busses on power up.
• SW1-1 OFF disconnects the module outputs from the audio busses on power up.
Setting MASTER
If this module will be the master sync source in a IO93 or IO94 Frame, it must be placed in a red reserved slot. Select the input
to use as clock reference using the web browser interface.
• SW1-2 ON sets this module as clock master for the frame.
• SW1-2 OFF if this module is not clock master for the frame.
Front Panel LEDs
To avoid audio bus conflicts when installing or replacing a module and the configuration is unknown, disable the output bus
drivers by setting BUS-EN = OFF before inserting it. If all settings are done remotely and the unit fits into the frame’s bus as-
signment scheme, remove it and set BUS-EN = ON.
