I've had an EFIS-D10A and an EMS-D10 on the bench for a while, and just got around to installing them.  When I bench tested them with v5.1 firmware and test connectors the DSAB connection worked and the EFIS was able to find the EMS and configure the network with 2 devices.  Cut to a couple of months later.  Both units have been installed and wired.  The EFIS didn't recognize that the EMS was on the bus, so I tied to reconfigure the network, and the EFIS only found 1 device (itself).  Lots of wire chasing, etc, nothing helped, so I updated to v5.4 firmware with no change.  I've checked out the wiring pretty well, even tried a different harness with nothing but the DSAB lines and power to each unit with no joy.  Anyone got any suggestions on what to try next?  Yes, it's wired A-A and B-B. :) All other sensors, etc, seem to work just fine.

Spoke with tech support this morning, it looks like they'll go back to the lab for checkout/service.
