I haven¡¯t looked at the pinouts lately, but the Camera DB9 on the MXP codecs could also provide power to a Tandberg camera.
?
Wondering if someone connected oddly wired serial cable to the camera control port instead of the external control port (IIRC, they¡¯re right on top of each other)
and that power was enough to make things very unhappy.

I¡¯ve never had an issue with serial control of any Tandberg/Cisco CODEC and I have multiple clients with dozens of serially-controlled SX80s each.
