Can you tell I was a HW engineer? And then a PHB*? Software was just a SMOP**. Everything is easy when someone else has to do it. And mistakes are obvious once someone has pointed them out.

From: George Skorup Sent: Wednesday, July 15, 2015 8:21 PM To: af@afmug.com Subject: Re: [AFMUG] pmp100 pmp450 sync calculator issues I updated a 900 AP. Looking at /engineering.cgi on this 13.4 AP and a 13.1.3 AP, the current frame configuration matches. The frame calculator is definitely broken. I see what the difference is now. The new calculator shows max range air delay as one-way, while the previous calculator shows round-trip air delay. Somebody forgot to do math somewhere. So the new calculator needs one-way air delay added to the AP's Rx Start value. Not the end of the world, but yes, confusing.

Go to one AP that is on 13.1.3 and another that's on 13.4. Log in and change the URL to /engineering.cgi and look at the "Current Frame Configuration" on both radios. They should match. If they don't then... uh oh. I don't have enough stuff updated yet to do this myself.

So is it the new one or the old one that's wrong? I just ran your dimensions on a 450 AP running 13.2.1. I got the same as your FSK on 13.1.3. Apparently something changed after 13.2/.1.

I can�t believe cambium never caught this but the tech acts like wow, that�s weird?�� Really?�� So I am trying to figure out if it is an error, or if it matters the software version, that said if people start upgrading to 13.4 on 100 your calculators will change, at least with my settings, so be careful to check your settings again after the upgrade.� I will post my findings with support.� Here is a screen shot of the same radio with 13.1.3 and than with 13.4, you will notice that the difference in software changes the ap start receive time by more than 600.� I would assume that you really don�t want to be off that much.� Any insight on this would be great! � � � � Craig R.
