Communications Support Forums

I am converting a dash mount XTL5000 O5 to a remote mount. I am also adding a UCM to the radio. On the flex the goes from the brick to the TIB (P/N HKN6190C) the following it printed on the ribbon

"Not To Be Used With Version A or B HLN6918 / HLN6919 Secure Interface Board)

The interface board I have is a HLN6918B. My question is do I need a new ribbon cable? New TIB? New secure interface board?

The part number on the TIB is PMNU1036D

Thanks
