This has a much clearer history in coming direct from the original user and 'working'. No problem acknowledging the original owner was London Underground, and this camera was swapped for a more modern model to get this one for the museum. It smells slightly of tunnels but has not been into fires or had the inevitable naval / brigade knockabout.
Initial checks are good, correct current draw at 430 mA, some iris motor noises as usual during startup and the external video is OK with a thermal image. All that seems to be missing is internal video.
A lot of time and effort can be saved by not 'undressing' the camera.
Just slacken the harness to release the power cable and then the camera can be removed complete by releasing the outer ring
There is enough slack to power the camera from the battery unit with the cables in situ. Final setup needs this arrangement as it is very sensitive to the input voltage (8.7V).
Diagnostics are OK on another supply wired into the PCB directly or making up a lead for either the Cannon plug or the 8 way input connector
