Chapter 2: Connecting the FOH Rack 9
Connecting the FOH Rack to the Stage Rack
The FOH Rack is connected to the Stage Rack with the Digital Snake cable (available separately from Digidesign). It is recommended that you use a second, redundant Digital Snake cable connected to Snake 2 ports on each unit.
To connect a Stage Rack to the FOH Rack:
1 Connect the send snake to the Stage 1 Out port of the Stage Rack to the Stage 1 In port on the FOH Rack.
2 Connect the return snake to the Stage 1 Out Port of the FOH Rack to the Stage 1 In port on the Stage Rack.
The connectors on Digidesign’s Digital Snake cable are color coded, so that the white connector connects to the white-outlined
ports on the Stage Rack and the FOH Rack.
3 If you are using a second redundant snake, connect it to the Snake 2 ports on each unit in the same manner.
If you are using a second redundant snake, the primary and the redundant snake must be the same length.
When the FOH Rack and the Stage Rack are powered up, the primary snake connection is indicated by the solid Active LED
(marked “Active”). If the Snake Signal LEDs flash, a Snake connection has not been established.
If there are problems with the Digital Snake connection, double check that all the BNC connectors are fully secured. If the
problem persists, try reversing the connectors connected to the In and Out ports on one end.
