SignaLink USB with Motorola XTL5000

[whkr590]

Does anyone have any experience using a XTL5000 with a SignaLink USB? I wrote a Java program to detect speech and perform speech to text analysis and then playback pre recorded responses -- it works with my computer's microphone and speaker, but I am essentially trying to use my XTL5000 as an input and output for the program.

I followed this pinout reference for the 25 pin out on the back of the XTL5000 brick: XTL 5000DB25 pin out

Here is the pin connection I am currently using:
SignaLink G -> XTL 10
SignaLink PTT: XTL 1
SignaLink MIC: XTL 8
SignaLink SPK: XTL 9

The PTT flickers on at off extremely fast when an audio is played, keying up the radio on and off multiple times per second. As for input and output into the computer, all I can get is a high pitched hum or sometimes an extremely quiet and low quality transmission if I play a very loud sound.

If there is anything I am missing, please let me know. I'd appreciate any guidance and open to trying new ideas as well.

-Thanks

To be clear, is your radio the XTL5000 MP (Mid Power) with then 26-Pin rear accessory connector (J2) E/W Dash/Remote CH, or is it the XTL5000 HP (High Power) model?

There is no "REAR" DB25 connector on XTL5000 HP radios. Do you mean the DB25 pictured on the TIB in the photo below?
