Accessory Connector
The accessory connector is a blue edge-connect PCB connector. See the example pcb for the layout of a mating PCB. The following table matches the pinout when looking into the side connector:
| Pin # | Function | xxx | Pin # | Function |
|---|---|---|---|---|
| 9 | TX (Out) | ------ | 10 | ? |
| 7 | RX (In) | ------ | 8 | GND |
| 5 | ? | ------ | 6 | ? |
| 3 | ? | ------ | 4 | ? |
| 1 | ? | ------ | 2 | +24V |
