Interesting how the 450i and 650 product lines seem to be converging. Similar mechanics, same mounting brackets, and the 450i user guide gives several powering options including 802.3at but also for AC+DC powering, the latest incarnation of the PIDU, P/N C000065L002A. But 450i does not seem to support the “recovery” function.

Perhaps there is a circuit that needs a frequency selective open that will be shorted for regular POE but something that chokes out the higher frequency. I wonder what the frequency is. Don’t know if I have a PIDU around here I could examine. If anyone has one that they want to open and photograph it might be fun to see if we can figure this out.

In the PTP400 datasheet it says there's a frequency-selective short circuit, seems on the "indicator" pair of wires 4&5; I cannot find similar information in the PTP600 datasheet.

But it is vague memory that is possibly a hallucination. I wonder how the reset signal works...

I think that's the same problem you'll have with all injectors besides the cambium one.

I tried with the WB / McCownTech GigE-POE; the injection and ethernet connection worked fine but the PTP500 radio always thought the reset button was pressed in so it wasn't very useful.
