XBee 5V/3.3V adapter board

J^3

Good Evening All,

I am trying to establish communications between my PC and an XBee Pro series 2 transceiver using the 5V/3.3V adapter board and my PDB. On the PDB is a 232 level shifter which I have wired DOUT of the XBee to tx of the level shifter, and DIN of the Xbee to rx of the level shifter. When I try to query the XBee from the X-CTU software I get nothing. Also, the yellow, green, and red LEDs are on, but no blue. Any help would be appreciated.

There are 10 types of people that understand binary, those who do, and those who don't.

P.S. When I try the same setup on my PPDB(has a MAX3232 for 3.3V devices) with a straight through adapter board, all works fine. Is my 5V/3.3V board bad?

Success! I started thinking that maybe the MAX232 on my PDB might be bad, so I took a dip package I had in my toolbox and interfaced it to my 5V/3.3V XBee board. Using X-CTU I received a response of "Communication with modem..OK" YEAH!! Now to get the two talking together.

P.S. I have to also fix my PDB

Are you sure the MAX chip on the PDB is damaged? I have found that often customers will simply have the RX/TX reversed in perspective to the driver and DB9.
