Hi Michael,

Is there a 5V / 3V printed on the PCB? This is would
be adjust the CAM voltage. HOWEVER:

really old CAMs use 5V internally & externally
(=>Jumper on 5v)

Newer CAMS use 5V externally and 3.3V internally
(=>Jumper on 5v)

For the future there where some plans to make CAMs
uses 3.3V externally and 2.5V internally (=>Jumper on 3v)
This is to decrease heat during operation. To my knowledge
however there are NO CAMS which support this, so the
jumper always should be on 5V

If the -C Version of the CI is (basically) the same as the -S
Version, this jumper is for the CAM voltage

>(My CI is marked on the PCB (on the inside) PCCA Rev 1.6.)

If it where a -S Version I would say you are out of luck as
the 1.6 Rev doesn't work with convergence stuff. I don't
know if this also applies to the -C Version.
