Chapter 10: AES I/O and HD Modules 107
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.

25-Pin D-Sub Pinout
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
assignment scheme, remove it and set BUS-EN = ON.
Status LED
Green Status OK
Green flashing Module is under FC972 Remote control
Red
Status is bad, remote reading of the status with GUI is
required. The FC972 Remote has probably issued a SNMP trap.
MASTER LED
Off The audio bus interface clock must be provided by the frame
Red DD915 is clock master for the frame
