innovation first breaker panel

[Jeff 801]

does any one know what the pwm plug and serial ports are for

if you want to know why I'm using it on a demo bot

[Jeff Rodriguez]

You can get info from the IFI page: http://ifirobotics.com/circuit-breaker-panel.shtml

And their reference guide: http://ifirobotics.com/docs/breaker-panel-ref-guide-2005-revnc0.pdf

It mentions the serial connection, but doesn't say anything abut the PWM connection.

I believe the PWM port is actually a serial port, I may be wrong. The serial port is used to send info about which breakers are tripped to the RC. The default MPLab code already has support for that data.

[Phalanx]

It has two serial port interfaces, but only one serial device.
The Standard DB-9 port and the PWM port TX, RX, GND.

Of course IFI says you shouldn't use the PWM connector. They didn't say you can't however.
