Thanks Erik.
The part I could not remember, and we did not document, is if we set the second pair of ID-1s up using RPS in addition to DD mode. Will go test that and update our ncrdstar.org wiki to show detailed radio settings. It has been a few years since we did not have enough gateways up to deliver service to all the MCM aid stations. But we do have enough extra ID-1s so that we can set up the Aid 10 relay point if needed. We still use D-STAR DD for support to the aid stations. We also still set up 9600 bps packet as the USN Medics want redundant service using different technology.
Another comment. In past years we could "cheat" using cell phone broadband modems at the various aid stations. Last year for the first time this service simply broke. We speculate that there were so many runners and spectators with smartphones that the service fell apart. We think this as up to Saturday afternoon every think worked fine with cell modems but Sunday morning on race day did not work. So our D-STAR DD access point and AX.25 9600 bps gateway proved to be necessary. (again).

We have an article on how to do this in the Spring 2011 CQ-VHF magazine.
The ID-1 is an Ethernet bridge. Use a plain Ethernet cable from the ID-1
to the PC at each end. The stock ID-1 Ethernet F-F connectors are often
defective check those. Both PCs need fixed IP addresses and to be in the
same subnet. (One test is to connect the PCs to each other first by a
crossover cable first). The callsigns should be a mirror: End 1 My
WE0ABC UR: WHOXYZ End 2 My: WH0ABC UR: WE0ABC Shut off all the repeater,
RPT-1, RPT-2, GW and duplex stuff- you are in DD mode. The radios should
start to chat back and forth and exchange callsigns if the RF side is ok.
