XBee PWM

I need a XBee to transmit a PWM signal to my electronic device. this is my setup:

CPU -> USB/FTDI -> XBee adapter kit -> XBee(1) -> XBee(2) -> (PWM) -> electronic device

If anyone could offer some advice on which pins to use of the XBee(1) and XBee(2) and how to manipulate the X-CTU to program the XBees to output the PWM it would be greatly appreciated. Also, references to other forms addressing this issue will also be greatly appreciated.

Thanks!

TL;DR : How to setup XBee to transmit PWM in hardware and software
