Mystery Pins On IP Camera Board

[megahurts]

[FONT=&quot]Hello,[/FONT]

[FONT=&quot]I've got a new IP camera and and am just trying to figure out the PIN outs to connect the wires. [/FONT]

[FONT=&quot]On the power outlet there are 4 pins, 12v CMT_R tap, CMT_T tap and G. [/FONT]

[FONT=&quot]I've never seen the CMT_R/CMT_T pins before and am not sure what they are. I've googled a bunch and can't find an explanation. Maybe these are RX/TX pins?[/FONT]

[FONT=&quot]Does anyone know? The cam pin out / cam can be seen here :[/FONT]

I've circled (in red) what I believe to be the four-pin console port connector. Connect GND to any of the four assembly screws at the corners of the board. Use a USB-to-TTY adapter and connect RXD and TXD to the center two points. Use 115,200 baud and 8 bits, no parity. If you don't get data, swap RXD and TXD and try again.

Thanks, I'll give that a try.

In the limited docs they have, they mark the 12v & ground on the top right jumper, and the port already has a wire to board connector. RS485+/- are also tagged on the docs on the bottom jumper. I'm just not sure about the 2 pins in between the 12v+ and ground labeled CMT_R & CMT_T.

CMT_R would likely be "Receive" and CMT_T would likely be "Transmit".
