CS Routing is a special control method that allows external devices to control routing within the RM2200D. That way, an external device can control which internal audio signal of the RM2200D is routed to a certain audio output. A typical application for CS Routing is the use of a DHD Router Control Panel RM420-018 or a Yellowtec Intellimix together with a RM2200D.
CS Routing uses the Channel Status Bits of the AES/EBU stream to send control data to the RM2200D. In turn, the DSP frame puts the requested audio signal on a pre-defined output. All signals available within the RM2200D can be routed to the output, actual details of this process depend on the configuration of the Router Panel or Intellimix.
However, this will only work if both the input and output of the AES/EBU signal share the same RJ45 socket on a RM220-111 Digital In/Out/GPIO module!

To use CS Routing, you need to configure a RM220-111 Digital In/Out/GPIO module within the DSP frame. Also, it will only work in conjunction with a DHD Router Control Panel RM420-018 or a Yellowtec Intellimix. | |
To set up CS Routing, do the following:
Connect a DHD Router Control Panel RM420-018 or the Yellowtec Intellimix to a RM220-111 Digital In/Out/GPIO module. Make sure, that the control input and the output you want to use for routing share the same RJ45 socket! (see also RM220-111 Digital In/Out/GPIO module, 8 channels)
Start the RM2200D software in Configuration Mode, connect to the DSP frame. Select the tab Frame I/O in the configuration dialog.
Find the RM220-111 Digital In/Out/GPIO module you connected the Router Panel or Intellimix to. Open its configuration dialog by double-clicking it.
Select the digital output the external device is connected to. Check the checkbox CS Routing information for this output.
Upload the new Config file to the DSP frame.
Now the Router Panel or Intellimix can send control information using the input associated to the output you just configured. The output will then carry the audio signal selected by the CS Routing commands.
