Unable to connect XBee Series 2 between USB Explorer and Arduino

I recently purchased 2 ZigBee Series 2 modules. I followed all the steps mentioned in [the difference is that instead of having to PC I have one PC and the other one is an Arduino board. I am using [url=http://allsensor.in/ProductDetails.aspx?CID=S%2fqIMmjstZg%3d&Counter=0&SEOType=BSuwhmB9Ll4%3d&PID=7lukD74%2fdY0%3d&CType=ZgDIC937E8s%3d]This USB Adaptor](http://examples.digi.com/get-started/basic-xbee-zb-zigbee-chat/ basic ZigBee Chat setup [/url) and this XBee Adaptor TTL

I also tried various sites on the net but both the module refuse to talk :blue: . Below is the Coordinator and Router settings.

What am I missing :? Eventually, there will be more than one XBee’s but to start with I want to get a point to point chat working.

Your PAN Id’s “ID” need to be the same. Change the coordinator to 1111 or the router to 2001.
