ADAHRS fail on upgrade to 5.1

[RVDan]

I am just completing my SV installation which includes 2 displays and 2 ADAHRS. On initial startup, the left display was at version 3.1 and the right display was at version 4. I used the single file to upgrade to version 5.1 on the right display, before realizing the left display was at 3.1 and had to use the method with multiple files for that one.

In the meanwhile, the ADAHRS came on line and everything was fine except for the version mismatch between the 2 displays. After going home and getting the necesary files to upgrade the left display, it was upgraded to V5.1. After the upload and installation it was verified that all devices (including both ADAHRS were present in the network configuration and showed good. On exiting setup, the PFD was X'd for the ADAHRS functions. The ADAHR calibration is also grayed out as the ADAHRS are shown offline. I have tired the following with no fix.
1. Verified network configuration (shows ADAHRS there and good)
2. restarted all devices with a complete power cycle
3. Reloaded V 5.1 to both screens
4. Reverified network configuration (shows ADAHRS there and good)
5. Power down all devices and re-powered.

Since the ADAHRS were previously fully functional, I am assuming there is no wiring or ADAHRS problem.

Anyone encounter this and or a fix?

Thanks
Dan

We've seen that here when upgrading screens with different previous versions, like you had there. Have you tried performing a new network configuration (not just looking at the status)?

If not, try this:

1) Disconnect the ADAHRS from the system (pop its 9 pin connector off at either end of the harness)
2) Do a network configuration
3) Reconnect, reconfigure

That help?

I did try the network configuration. Will try to disconnect the ADAHRS per your suggestion..

Your suggestion solved the problem. Here is what I did:

Disconnected both ADAHRS connectors.
Powered up Skyview system (both displays)
Performed a network configuration which of course removed the ADAHRS from the connected component list.
Powered down Skyview.
Reconnected both ADAHRS
Powered up Skyview
Performed a network configuration, which now found both ADAHRS. Exited setup and ADAHRS were functional.

Thanks.
