Batboard

Trying to connect a "NIB" HLN6911H Grey face O5 remote mount control head with a XTL5000 and I get a FL 05-93 code, regardless if the control head is connected to the brick or not. The radio had previously worked with an O5 control head, so I doubt it is in the brick. Plugged in a W7 head and could read the radio, info as follows:

DSP R19.50.01
Firmware R20.50.09
Software R20.01.00

Tried syncing the control head and the software could not open the USB port to the head. I am sure I am missing something obvious, any suggestions??

TIA

TIB and CHIB must match, I’ll bet the CHIB is a later variant than the TIB, or vice versa.

I should have marked this thread closed, the issue was the flex cable inside the control head was only connected on one end. The control head was NIB, so apparently this one slipped through Quality Control.

After plugging the cable in the head is now working fine
