MADI 1 to 4
MADI ports 1 and 2 are not available for external use. They are used internally to support the RAVENNA card
(7).
MADI ports 3 (and 4) can be used to connect multi-channel digital audio (1 x 64-channels). The two ports provide
main and redundant connections: MADI 3 is the primary port and MADI 4 is the redundant port. The redundant
connection is optional.
4
ETHERNET
The ETHERNET port connects other devices to the Compact Engine control system. In a crystal standard
configuration system, it must connect to the host PC running the DisplayDock software.
5
CAN
The CAN bus port connects to the control surface frame.
6
RS 422
The serial port can be used for debugging, but is usually left unconnected.

Expansion Slot 1 - AoIP Streaming
Expansion slot 1 is fitted with a RAVENNA IO Card (952/38) to stream audio to and from an IP network.
By default, 32 stereo streams are transmitted and received via the ETHERNET A port, while ETHERNET B
remains unused. The streams are fully compatible with AES67 and RAVENNA. Optionally, you can re-configure
the two ports to support redundant streaming (via SPS).
In both cases, the streaming network
must
be properly managed and configured.

Expansion Slot 2 - Digital or Analog IO
Expansion slot 2 is fitted with either more digital or more analog IO depending on the console edition:
·
Fader Start: AES3 IO Card (952/32) - 4 x AES3 inputs and 4 x AES3 outputs.
·
Button Start: LINE IO Card (952/31) - 8 x line level inputs and 8 x line level outputs.
