The 450i will power on with any polarity. So you can put + on 4&5 and - and 7&8 and it will still power on...However, for sync to be received, 4&5 needs to be return, and 7&8 needs to be power.
If you are powering on all 4 pairs, you still need to honor this polarization on 4&5 and 7&8 for sync to be able to be received. You can put either polarity on 1&2 and on 3&6. -forrest On Thu, Nov 24, 2016 at 11:32 PM, George Skorup <geo...@cbcast.com> wrote: > I'm confused.
