XBee and RS232

Hi!

We're planning on using Arduino for a telemetry system. The input data comes from RS232, and we'd like to communicate with another Arduino via XBee. We bought already the XBee shields as well as the Arduinos. The question is: would a RS232 shield for Arduino use the same ports as XBee? Because they should be working at the same time...

Hope I made myself clear.
Thanks,
Carlos

P.S.: The RS232 shield we're planning to use is: http://dx.com/es/p/rs232-serial-port-to-ttl-converter-communication-module-for-arduino-148963?tc=EUR&utm_source=GoogleShoppingSP&utm_medium=CPC&utm_content=148963&utm_campaign=Arduino_&_Suministros_de_Chips_para_Microcomputadores&gclid=CPvT1uns2bcCFWfItAod-DcAOQ and now we've several digital pins free.

The RS232 shield we're planning to use is

known. The XBee shield is still a mystery.

The question is: would a RS232 shield for Arduino use the same ports as XBee?

I presume you mean pins. Without knowing both shields, we can't answer that question.

Sorry! The shield is this one: http://img1.mlstatic.com/arduino-shield-xbee-shield-v11_MEC-O-3287165944_102012.jpg (ArdunioXbee v1.1)

One more question, what if we use CAN instead of RS232? Which CAN-shield (if any) would you recommend so that we have no problems with our Xbee shield? Thanks!

I'm supposed to determine the schematic of that shield from a picture? I don't see how.
