The HAMKit VDAS board has two connectors:
- BNC (or RCA)
- Miniature 6 Way JST SH PCB connector
To use, simply feed in a composite video signal and upon correct sync being sent, then the SQL/PTT output will go low, the on board LED will light and Thru Audio enabled. Changing a solder link, the output can be inverted,if required.
Connections are taken in/out to the Miniature JST 6 pin socket and supplied cable.
4-SQL Output (LED, PTT, Relay etc)
3-Video In (parallel to the BNC input)
1-+6.5v to 16v DC In
Should you wish, you may bypass the BNC socket and just use the Miniature 6 Way JST SH PCB connector for both Video input and Audio/PTT outputs.
