Hermes Lite 2, N2ADR Not Operating

[paul chancellor]

During a current project to add auto band pass to operate a Xiegu Xpa125, (TechMinds  https://www.youtube.com/watch?v=nGPKPGUB4O0) I discovered that the HL2 was not sending commands to operate the N2ADR relays.  This problem may have been recent or it may have existed since I purchased the HL2 from MakerFab.  Scoped all 20 pins of HL2/N2ADR connector and failed to find any signals to operate the relays.

HL2:  Build 9

HL2:  Original gateware from purchase  (2.0.991.0)

N2ADR:  Rev. E5b9

Running Thetis:  2.10.3.12x64-HL2

Operating System:  Windows 10 Pro

If you know of this problem or have guidance/comments please let me know.  In the meantime, Thank You !

Maybe I do not fully understand your question but has this been set in Thetis under general, oc control, n2adr filter ?

Just in case, you did not mention anything about that in your initial question.

What is VFO A and VFO B set to. You have the 10/12M and 160M filters activated. This is proper for listening on 12m or 10m. Probing the hardware does not show pins 6 and 7 low on the OC output? Other pins will be floating as they are open collector with no pullup present.
