I have connected the VCC, RX, TX, DTR and GND pins to the pins on USB to serial converter Silicon Labs CP210x.

I am able to read the Xbee , update its firmware to Xbee End Device API. But when i try to write settings to it most of the time its not working.

At the Same time when i connect Xbee Series 1 I face no such problem.

When I checked the data sheet of Series 2 and Series 1 i found PIN 9 is DTR active high for Series 1 and DTR active low for Series 2. Could it be the problem.

Yes that is part of it. You also need to use hardware flow control (/CTS) as an End device sleeps by nature and will before you can start writing the settings to it.
