Chapter 3: IO93 Modular Frame 31
Control Bus
Each frame must be fitted with an FC972 Remote to externally configure all modules (except analog line in/out and WC984) and
control mic preamps remotely using a web browser or console. Install only one FC972 per frame and up to two SY983s (for re-
dundant operation, differentiated by Master/Slave setting).
A Module’s system ID consists of the Frame ID + module CAN ID. The Frame ID is determined by the FC972’s IP Address/Sub-
net/Host Address. The FC972 must be assigned a unique IP Address based on the frame’s role within the system. A CAN ID must
be set for each externally controllable module. Most modules have 32 CAN ID settings available but the AD914 Remote Mic Pre-
amp has 16.
The FC972 and SY983 have default module CAN IDs that do not interfere with those of other modules. The internal CAN bus
must be terminated once per frame, either on the FC972 or SY983.
Using the CAN Address switches on the FC972 or SY983 is an older method of setting the Frame ID. An explicit CAN Address must
be set only when employing a hardware CAN-BUS remote controller to configure frames. In System 5, the Frame ID is set with
the FC972's IP Address for configuration using a web browser interface.
