Thanks Jain,
I have seen that also. But now 62 is working OK (lock). I've fixed invert problem in a primitive way. I used ON/OFF relay in converter box (switch for 110V external). Disconnected all wires for 110V and used contacts on this relay to disconnect RB2 (NED) in Canton3. If you select chnannel that is not coded - switch the box off and Canton will not lock. When you watch coded channel - switch txe box on - it will lock. I know this is primitive way to fix it but I am hardware (RF) engineer and don't know much of assembler programming, but defiitely can be fixed by code.
Regards,
Vlad
