810 vs 800 PTP

Hy, i have question for all member, can i connect my PTP 810 existing radio to the new one backup radio PTP 800 ? Thanks for your attention

Could you be a bit more specific about how you want to connect them?

Are you looking to build a link with PTP 800 at one end and PTP 810 at the other end? Unfortunately this will not work.

Ok Mr. Thomas thanks a lot for answer my problem, actually i have 1 link PTP 810, and i have problem on the remote site, but i dont have another PTP 810, i just have back up 1 hop PTP 800, so i think i can replace whit PTP 800, but unfortunately it cant work, correct ?
