Hello
I imagine well that my quality of explanation is horrible.
I made at best with a tool of translation.
Thank you for your patience.
These problems prevent me from sleeping.
Good news, I found the last breakdown which prevented the 861v4 from working:
It was the card 800-IA00.
There was a capacitor with a son of broken.( 1000 uf 16v )
It made bad contact and anomalies.
It has firmware 861-425, is it necessary that I the upgrade?
For 800 it's getting more complex:
Breakdown : 2 cards display fixed behind the facade.
It is confirmed, because it works with the cards of the 861v4.
I have not managed to put the reader in region zone 2 or free yet.
It has firmware 800 : 2.48.
