Connection and connectors description

There is DB25 female connector with PTT in, power supply and output pins. This controller could have positive or negative output drivers. It means - when PIN is switched remotely ON, the supply voltage is switched to this output PIN (for positive driver TBD) or switched to ground (for negative driver ULN). There is also internal electronic fuse (short protection).

You can directly connect any of your devices, relays, preamp etc. Output pins could work as simply ON/OFF switch and also could be grouped together in 1-of-X. PTT IN could work as a hot switch protection - disable switching while PTT is in transmitting mode.
