Kenwood 2000 ACC2 transmit problem

[W4EET]

I am working on a TS2000.  I set it up for WL2K and had it working yesterday.  I wired the ACC2 cable to work on the SUB input/output.  I am using a KPC-3+ TNC.
Now when I send a message to it from Winpak it keeps transmitting on the Main side.  It receives on Sub and transmitts on Main.  I pressed the split key and it did not help. I did a full reset and it did not help.
It was working yesterday.  Receive and Transmit on Sub and sending the signals through the ACC2 port.  The TNC was happy.

If I use the mic, it transmitts and receives on the Sub side.

Any suggestions?

I may have found something.  In the menu setups there is a setting for using a TNC.  You select Main or Sub.  I will try this out.  Maybe its operator error.
