power led on board is glowing.
i m trying to connect xbee module(XB24-awi-001rev) to computer via rs232 cable.
I don’t know how you’d connect an XBee module to a PC with only use of an RS232 cable, so this doesn’t surprise me. I’d recommend looking into purchasing one of our XBIB development boards. The dev boards also come as part of our development kits if interested.

I’m not sure what “board” you have with a power LED, so please elaborate on this…
As for connecting with an rs232 cable, what Admin didn’t say is that the XBee’s use TTL for RX and TX, and PC’s [typically] use RS-232 for RX and TX. The voltages are completely different- one ranges from 0 to +5 or 0 to +3 and the other ranges from -15 to +10 if I recall. So to get from one to the other you either have to do some engineering or get a chip to do it for you and do some wiring or buy a board. FTDI seems to be the grandaddy of ttl-rs232 chipmakers, and just about any board you get to change ttl to USB or ttl to rs-232 (or rs-485) will have an FTDI chip somewhere on it.
Digi makes a thing called the XBIB-U-DEV that sells for around $80 USD. I’ve got one in front of me and it works great. They have a ‘lesser’ version of the same board that runs about $10 cheaper-- best I can tell it lacks a few LEDs and maybe some buttons. I’m not exactly sure what the buttons do, but the flashing LEDs are nice.
