Null Modem Jumper Position

The RS232 port on the Just Add Power device has a null modem jumper on the bottom that determines the transmit/receive pin position of the RS232 port.

Please see the [3G] Null Modem Jumper Pinouts article for the correct position. The Flux Capacitor always uses the Crossover position.
