Andrey,
Thanks a ton, I looked over the pdf and understand exactly what you are saying… I will be using my own POE injector inside my circuit so I can be assured the polarity will always be correct.

CR2 has 4 pins - 2 of them are marked with "+" and "-", two others are inputs form the network cable contacts. The easiest modification will be to connect straight "+" and "-" both to the opposite without crossing. In that case network connector contacts 7 and 8 will become "+" of the power, and 4,5 - "-". If you cross over the jumpers - the polarity will be opposite. If you do such modification you need to make sure that the polarity of the power applied to the camera is correct. I would double-check it with the multimeter - make sure that "+" on the diode bridge rings to 7,8 on the connector and "-" - to 4,5 (if you use straight connection). And then verify that your power source has "+" and "-" on the selected cable pins. Andrey
