Telemetry question

Hi guys, quick question here...If i am using my devo8s running deviation to fly a walkera qrx350 quadcopter and it has spektrum ar6210 rx installed and all is working good and i want to add the walkera telemetry unit will it still work cause the tx and rx is running dsm protocal? or am i going to have to install a devo rx to get the telemetry unit to work? I don't quite understand how the telemetry unit works it has its own antenna for transmitting the data but if the tx is bound as dsmx or dsm2 how could it work cause the telemetry unit is obviously devo protocal..

thanks..

Thanks for the reply...kind of what i was thinking but just was not sure.Good thing i didn't order the walkera unit lol looks like i'll be getting the Spektrum instead...or grabbing a devo 7ch rx
