Modular I/O Configuration Guide8

Control Configuration

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).

Frame and Module Addresses

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. The AD914 Remote Mic Preamp has 16 CAN ID settings available, whereas most

other modules have 32.

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. CAN Address switches on the FC972 and SY983 must be

set to their non-active default values as described in their sections.

Frame Space

Frames have module slots in one or two backplanes. A module requires either one or two slots. Frames with two backplanes have

a front and rear plane. Make sure there is enough physical space in the frame for the specified modules. Each frame’s section in

this guide lists the required space per frame.

Power

Each module is powered by the frame’s +5 VDC rail. Power draw of the modules fitted in the frame must not exceed the frame’s

PSU capabilities. Power consumption for each module and power capability per frame is listed in each section of this guide.

Audio Busses

The Modular I/O backplanes are passive and all frame audio routing is set on the modules: Source audio is assigned to a bus routed

to a number of destinations. Each Modular I/O backplane contains 32 audio busses (S1–S32).

All I/O modules provide a 2CH mode (two audio channels per bus). Many modules also feature an 8CH mode (eight audio chan-

nels per bus). Source and destination modules must be set to the same mode.

Some frames consist of multiple audio zones that decouple the audio busses between different frame sections. This supports higher

signal densities per frame.
