450i AP losing GPS sync

#1

Cambium 450i help - on the sync status page, under the “Sync Pulse Status - Main/Power Port” setting it keeps flipping from “no sync” to “receiving Cambium sync” then back again to no sync. What should I check on this? Sync pulse status is around 63% for some reason.

Using CNpulse for sync, software on V22

What does the sync status tab show?

I think it is fixed now. I did a climb and changed the GPS wiring to use the aux port on both, that seems to have taken care of it.
