Hi deanz25

You will have to connect the xDR16 to a PortB ACE module. We currently only support expanders connected to a Port B ACE module.

Hi brobinson81

Yes this is a valid configuration though there are some limitations with channel availability. There are only 64 channels available in totoal out of Port B therefor you will need to share these outputs with both Expanders.

All Channels 1 -64 are outputted to both xDR16 expanders so you will need to assign channels 41-56 as your Aviom channels which leaves channels 1-40/57-64 free for you to assign to MADI channels

Check out the routing diagram in the xDR16 brochure


and also the getting started guide


Hope this helps
