5i25+7i77+7i76+7i84

Hello!
I have a 5i25+7i77+7i76+7i84 card set. 5i25 has flash 5i25_7i77_7i76.bit . 7i77 is connected to connector P3, 7i76 to connector p2, 7i84 card is connected to 7i77 connector TB6. I have a problem with the 7i77 card. IO inputs and outputs work without problems. The only thing that doesn't work are the analog outputs. During the openloop test in pncconf, the analog output works normally. But when running Linux CNC, the analog output is non-functional. In the HAL meter I can see the analog outputs normally, but I still measure 0V on the card.
All other cards work normally.
I am attaching the current configuration of the machine.

Just a guess but

sserial_port_0=0200

Would be illegal for a 7I77 at sserial channels 0,1
(2 is not a legal mode for the analog section = channel 1)

sserial_port_0=2000 would be legal
since 2 is a legal mode from the field I/O section = channel 0

Yes, that's exactly the problem!
I changed it for the 7i84 card. I need to have the card in mod 2.
So what is the correct sserial notation for mod 2? sserial_port_0=2000?

sserial_port_0=2000 sets sserial port 0 channel 0 to mode 2

(this is the 7I77 field I/O on your current setup)

The 7i84 setup depends on the 7I84s sserial channel.
If the 7I84 is connected to the 7I77, it would be on channel 2,
if its connected to the 7I76, it would be channel 4

sserial_port_0=00020
Would set the 7i84 mode to 2 if its connected to the 7I77

sserial_port_0=00002
Would set the 7i84 mode to 2 if its connected to the 7I76

(the modes are set per channel, the leftmost digit sets the mode for channel 0)

The 7i84 card is connected via the 7i77 card. I tried sserial_port_0=00020 but the 7i84 card is still in mode 0

Sorry, can't count... those numbers should be:

sserial_port_0=00200
Would set the 7i84 mode to 2 if its connected to the 7I77 (channel 2)

sserial_port_0=00002
Would set the 7i84 mode to 2 if its connected to the 7I76 (channel 4)
