Environment

Cause

This is caused by setting the address dial on the back of the XR communication card (either SYXRCC or SYAFSU16) incorrectly.

Resolution

Check to ensure the XR communication card's address dial is set to a valid address. This problem has been observed when the dial is set to a position in between two valid addresses. If this has been checked and the problem continues, contact technical support.
