Modular I/O Configuration Guide38
Audio/Sync Zones
The IO95 frame consists of five discrete sync zones, each requires its own master sync source. Although this is typically an SY983
Sync HD module (or two SY983s configured in redundant sync mode), an I/O module with Master mode may serve as a master
sync source but not in conjunction with an SY983 in the same zone. Examples of modules with Master mode are MM935 MADI,
MM936 MADI, DD915 8ch AES I/O, DD916 8ch AES I/O, and HD944 16ch De-embedder.
Only one master sync module source should be present in an audio/sync zone except when using two SY983s in redundant sync
mode (see “SY983 Sync HD” on page 41).
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. Install only one FC972 per frame and up to two SY983s (for redundant op-
eration, 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.
Technical Specifications
To avoid damaging analog circuits, install a master sync source module before applying AC power.
