7i76 analog input

Hello,
I need your help again.
I can´t readout the value of the analog input from the 7i76 (see the picture).
The settings in the INI-File is as follow: 

loadrt hm2_pci config=" num_encoders=7 num_pwmgens=0 num_stepgens=5 sserial_port_0=10xxxx"

Please help me to find out the problem.
I use LinuxCNC 2.9.2.

Best regards
Ludwig
 

Just connect 24V to TB6 pin 4 and read
net analog3 <= hm2_5i24.0.7i76.0.0.analogin3 => spindle_load.bar_spindle_load

Does digital input 0 (same pin as Analog-0)respond?

If not, that suggests a communication issue

Yes, digital input shows 1, and the fieldpower is also connect.

 

That is a somewhat weird hardware configuration (50 pin FPGA --> 25 pin daughtercard), what does:

sudo mesaflash --device 5i24 --readhmid

show?

Also what is the 7I76 firmware version

DId you try mode 2?
 

I try mode 2, same result. Only there show encoder0 , encoder1 and fieldpower pin.

How to find the 7i76 firmware version?

And the 7i76 is connected to the 5i24 by DB25pin connector.

Here the 7i76 firmware version:

sudo mesaflash --device 5i24 --sserial
