Re: [AFMUG] Used PMP450 radio needed...

[George Skorup]

If you have a 450 SM sitting around, an email to Matt Mangriotis to ask 
if you could get a BH license key for it couldn't hurt. Maybe they could 
do a demo key or something.


They did come out with a Rev B 450SM board a year or two ago. Maybe the 
original doesn't do UGPS power...? IIRC, I've read here, on the Cambium 
community site, or both, that some don't even have the UGPS power 
option. And if your customer says the one they have does, then... I have 
no freakin idea.


And I'm pretty sure you need pins 1,2,3&6 for UGPS power. I never wired 
pin 2 previously for FSK and 450 APs to SyncPipes and boxes. Probably 
should have. Oh well. Not a big deal to replace a timing cable though.


The obvious simple/quick solution would be a Parasitic pipe, since the 
PTP450/450SM is only 10/100 ethernet anyway.


All I know is that I have/do use UGPS power with your SBJ Aux's on 450i 
APs. And I've also tested it with regular 450 APs with a RJ45 to RJ12 
adapter cable. Works in both cases. I have no PTP450 deployed or laying 
around to mess with. I have never bought nor touched a UGPS. Don't even 
have one CMM out there anymore. Sorry Cambium, PacketFlux is cheaper.

There is also a spec sheet floating around which claims that it had a 
rj45 aux port.  But that one looks like it's a half updated 450i ptp 
datasheet.

The PTP450 spec sheet states:

SUPPLY

So no UGPS power on the timing port?

I don't seem to be able to find one of these in the normal used

Anyone have an idea where I can get one of these?  I notice new
isn't that expensive so I guess it's not the end of the world if
I don't find one.
