On the startup screen there is a transmit tab. What do the transmit interlocks do and what are they used for.

    WIOth some exteral configuration you could prevent ransmission if your switch matrix did not have valid transmit anteanna connected, It could be used for preventing transmission when using exteranl T-R relays to prevent hot switching in line preamps/PA's.... Most likel;y on VHF/UHF converter systems. Other uses possible. AL, K0VM

    "RCA TX REQuest" - I can not seem to find any functionality for this connector. It has 3.281 VDC in any state (Disabled/Active High/Active) in RECEIVE or TRANSMIT. "Ground" this pin in any state does not inhibit transmit when transmitting in CW. The HW docs say "..grounding the center pin will prevent transmit from engaging" which is what the ACOM2000A will do provide but does inhibit appear to be working. The SW docs only show what states are available but no "signal" info. Perhaps, I am not understanding how this works or on the "wrong RCA jack.. " ?

    Patiently waiting to see when then this comes to fruition, along with holding off RF output until the TX ports finish their timing. Not so good for fast QSK, but good engineering nonetheless...

    The "interlock" TX Request input is NOT currently functional... is this correct?

    Yes, that is correct.
