Inex ZX-19 wiring problem

Hello, I’ve got a Inex ZX-19 sound board wiring problem.
robotshop.us/inex-smart-sound-board.html

I need to know which pin on the JST connector, is what type of connection. One should be a TX, one a RX, etc. Its not labeled in the directions, or on the boards stenciling, and I’ve not seen it defined anywhere by searching online.

I have the board mounted on a robot already. So testing the connections would be very troublesome. As I can’t simply remove the board without major dis-assembly.

Thanks for any help.

Thanks for the help
