Mesa 7i95

Hi Guys,

Help me please I'm lost: 7i95 with LinuxCNC 2.10.0 works fine except input pins on TB5 (input 16-23)
If I connect the same wires to TB6 input 0-3 then I see in HAL monitor if the status of the port is changed, but if I connect same wires to TB5 pin 1-6 (simply use the same connector head just unplug it from TB6 and plug to TB5) then I can't see any status change not even in HAL monitor even pins are there.
I tried all inputs on TB5 and none of them worked, but all inputs are fine on TB6.
What could be wrong?
I simply load hm2 _eth without any specifications (num_stepgens=5, num_encoders=5"
I tried it with fresh install from scratch result is the same and card is brand new, never used / connected any wire to TB5 before so I ruled out hardware damage as corresponding LEDs indicated (correctly) the status change on the board.

Thank you!
Tamas
 

Hardware damage is unlikely as the 7I95 isolated inputs well take up to 48V continuously
and even brief contact to 120VAC will not cause damage.

Is the 7I95 using standard firmware?

What does

halcmd show param hm2_7i95.0.inmux

show?

I use stock firmware, haven't flashed yet, here is the output:
Parameters:
Owner Type Dir Value Name
30 bit RW FALSE hm2_7i95.0.inmux.00.enc0_4xmode
30 bit RW FALSE hm2_7i95.0.inmux.00.enc1_4xmode

Thx a lot

Sounds the 7I95 has developed a defect
(It needed to pass a I/O loopback test of all I/O points before it was shipped)

Mesa can issue a RMA for evaluation, repair or replacement of the card.
Please email Mesa with the card name and serial and they will issue a RMA

Sad to hear but I've just realized that 7i95 does not have enough inputs for my project because I need at least +24 inputs so +/- 8 (which do not work now) do not matters and to be honest I don't prefer to return my card because I'm afraid it would required long time due to global supply chain issues, delivery times between EU and US, etc so I'm wondering would be an additional 7i70 good solution? Will it work together with 7i95 if I connect them through the serial interface?
Thank you.

Yes, it should work.
Might want to check Mesa 7i84, it is the same SSerial card but has 32 inputs and 16 outputs.
