Each control surface frame requires two connections: power and CAN bus. Please see Connector Pin-Outs for
pinning information.
All connectors are positioned on the rear panel, and so you must make sure that these are accessible. In the
table-top and countersunk versions, the cable tray has an open underside and rear access holes:
Table Top Surface (rear view)
1 CAN Bus (CAT 5e)
The CAN ports connect the control surface to the DSP Core and any extenders or key panels.
All CAN bus connections must be point-to-point; a switch or hub is not allowed. Use a standard (straight 1:1)
network cable: STP-CAT 5e with RJ45 connectors. Every frame is delivered with a suitable cable.
The maximum length of the CAN bus connection is 60 meters.
The CAN bus can be hot-plugged and so the cabling can be performed while the frames are powered.
