DSAB not online

When I power on all my instruments (D100 D120 Garmin296), I noticed that my EFIS was not sending OAT to the D120, which in turn prevents the %power calculation. Upon checking my network, the devices can all 'see' each other and I rechecked the configuration - but the devices are shown as "offline" in the network status, and the values provided list - normal e.g *OAT are shown as *?OAT instead. What does this mean, and how can I get them talking again?

So first, where is your OAT physically connected? It's either the EFIS's EDC-D10A or to the EMS directly.

The OAT is connected into the EDC-D10A, which in turn connects to the EFIS system. Thanks in advance for your help! I just can't solve this no matter what I try!

Just to confirm, the DSAB connection only required me to hook up the twisted pair (blue/green from memory)?  There is no DSAB ground connection directly between the two units, just the overall grounds back to the starpoint earth.

That's fine. So first, on the EFIS, make sure that OAT is set to type 2. Next, on the EMS, make sure that none of the GP inputs are set to OAT. Then do a configuration. Any joy with the OAT on the D120 (bring up OAT on an INFO intem widget to see if the data is making it over there).

What you've described is exactly the approach I tried last weekend.  No joy  :-/

The GP's are as configured in the factory. I have the OAT widget / read-out on screen on the EMS and the EFIS respectively - shows perfectly on the EFIS but nothing on the EMS, just a straight green bar with no number. I think it says N/A or something?

I will go to the hanger and repeat the process tonight, just to be sure.
