Xbee Pros series 2 not communicating

pan ID and baud rate for both Xbee is 2227 and 115200 respectively. everything else is at default.

I also have a Lilypad Arduino connected to a Lilypad Xbee, each are powered; TX and RX are switched beween the Lilypad arduino and Xbee. I want the Lilypad to send signals to my computer but the Xbees are not responding with eachother (the TX and RSSI indicators are not lit up).

Set DH and DL on the transmitting device to the Sh/SL on the recieving device
