PTP 820S-Wrong PIDU?

I'm programming  a PTP 820 S link. I can't communicate through the PIDU LAN port; nor do I get an Ethernet LED. System Support has so far been unable to help.

Searching, I see the 820 is supposed to use a specific PIDU, the N000065L001 (the black one).

I've been supplied the C000065L002 Power Injector (the tan; 2-tone blue one).

According to this link, I've got the wrong PIDU. Could this be the source of my problem?


Don't use C000065L002, AC+DC Enhanced Power Injector 56V, for PTP 820!

I'm sorry you've got the wrong PIDU.
