IQANdesign 5.03, no contact with some XR units

With IQANdesign 5.03, some radio remote modules implementing the XR protocol no longer works, the symptom is a No contact. 

 

The problem was caused by an update to the expansion module protocol, depending on how the radio remote implements the XR protocol it may not respond to the modified message. 

 This problem is now solved, in IQANdesign version 5.04.
