PTP820C pinout

I was looking for information on the PTP 820C pinout and came here.
I would like to know the pinout of the PTP 820C, specifically what are the (+) pins and what are (-). Or find out about compatibility, for example if it supports 802.3at / af compliant power injectors.
I consult it, because I am going to feed it with a 9dot PoE Injector called GigaSync that allows you to choose the pinout of every PoE port by inserting a small key into the device. So, knowing that you can correctly choose the key without making mistakes. It would be very valuable information for me.
I leave an image with the different options to map the pinout of each PoE port of the GigaSync.
