1.5.1 Main Features
Adding a BVRD2S to a BVRD2M increases the number of inputs
available by 12, the number of outputs by 16 and adds another 12
messages.
Up to five slave units can be added to each master, making a
maximum total of 68 inputs, 87 outputs and a maximum of 30
messages.
The slave units mount directly on top the master unit.
To minimise rack wiring, the power and communications
between master and slave units are through an internal data link.
1.5.2 Rear Panel Connections
Figure 1.3 — BVRD2S Rear Panel
All connections are made to the BVRD2S using RJ45 connectors.
The “Bypass All Call Enable” switch can be used to prevent an “All
Call” message from being broadcast to the selected outputs.
This is often required if one of the outputs is being used as a local
monitor.

For installations that do not require the full range of additional
inputs, outputs or messages, the Light (LT) slave is available that

outputs by 8 and adds another 6 messages.
