I'll appreciate it. I'd like to connect via P1 because i leave it for encoders in future and time has come (based on other users experience). I already use P2 and P7 for communication with mx4660.I've tried to add configuration to pncconf but TXEN2 TXDATA2 and RXDATA2 don't want appear, do someone know what I'm doing wrong?

Thats what inside file:

I'm not sure what you are suggesting

What firmware are you using currently?

I would probably make firmware something like

P1 = MX4660
P2 = 7I77
P7 = GPIO

Currently I'm using that:
freeby.mesanet.com/7c81_mx4660x2d.zip

Can I ask You to make it in way:
P1 = 7i77
P2 = MX4660
P7 = GPIO
if it's not plenty of work?
I'm asking because that will help me with arrange space in cabinet.
Thank You in advance

and in connection with photos above
I manually added config for pncconf for 7c81 and 7i77 and mx4660 but something is wrong in comparision to 5i25 + 7i77:
  i cant find where is mistake, everything looks ok, maybe You know?

7c81 configuration with 7I77 on P1, MX4660 on P2 and just GPIO on P7:
