Well someone sent a picture from the manual that says “either” basically… but I don’t think most of us are good at reading manuals… we would rather figure it out on our own ;-D
So why the spec sheet says -48VDC… as I said I can only point to practice and that many of our other radios are bonded to the chassis. Lumina is kinda an exception to the rule (why I have no idea). I’ll never forget that is how I was told to install my first licensed link, alone (roof top to roof top), a Stratex XP-4 in 38GHz. I was given the TX information, and told to “figure it out” even though lots of the people around me had installed lots of these links. Programming the IDU with buttons, was well, goofy. But I’ll never forget it (installing that first link). *************************************************************************** Daniel White - Managing Director SAF North America LLC Cell: +1 (303) 746-3590 daniel.wh...@saftehnika.com <mailto:daniel.wh...@saftehnika.com> Skype: danieldwhite Social: LinkedIn <http://www.linkedin.com/in/danielwhite84> *************************************************************************** From: Af [mailto:af-boun...@afmug.com] On Behalf Of Lewis Bergman Sent: Wednesday, April 29, 2015 9:28 AM To: af@afmug.com Subject: Re: [AFMUG] SAF Lumina power Probably because the next question is "Is that negative or positive?" On the other hand I agree. If the ground is floating, and I should but I don't remember, they could list it as either.

We say -48VDC since that is the telco standard (and some of our other radios are -48VDC only). *************************************************************************** Daniel White - Managing Director SAF North America LLC Cell: +1 (303) 746-3590 <tel:%2B1%20%28303%29%20746-3590> daniel.wh...@saftehnika.com <mailto:daniel.wh...@saftehnika.com> Skype: danieldwhite Social: LinkedIn *************************************************************************** -----Original Message----- From: Af [mailto:af-boun...@afmug.com <mailto:af-boun...@afmug.com> ] On Behalf Of George Skorup (Cyber Broadcasting) Sent: Tuesday, April 28, 2015 5:36 PM To: af@afmug.com <mailto:af@afmug.com> Subject: [AFMUG] SAF Lumina power I thought all the SAF stuff was +48, but the CFIP Lumina FODU datasheet says -48?
