Glasmaßstab EIA-422 an Mesa 7i85 (S)

Not sure what that issue is, the "cannot gain I/O privileges" is not related to index at all

I tried a few more things and just couldn't get anywhere. So I decided to take another look at the wiring and the 7i85. I noticed that the jumpers for the signal are not set to RS-422 (in the down position) but to the up position for TTL signal.
Unfortunately, the nine-pin TTL signal pin assignment is the same as the RS-422 assignment, except that A-, B-, and R- are omitted. The signals are then ignored anyway. So there's probably no point in changing the jumpers.
Or should I try?

 
 

I think I'm a little confused today. The card is installed upside down, so the jumpers are in the down position.
Now I don't know what to do next.

Can you post your complete hal and ini file set here?
Then I can try an duplicate your issue


Also if you know you have differential outputs on the scales,
you should leave the 7I85S jumpered for differential inputs.

Typically TTL encoder signals will not work if the interface card is
jumpered for differential signals, but differential encoder signals
will work if the interface card is jumpered for TTL signal



 

Just to be sure, are you running as user ROOT ?

What's going on with this site? It takes forever to load, or it's not even accessible. I've been trying to reply here for 35 minutes.

@tommylight
All other changes are executed, so why should it be any different with the index signal? Yes, it should be executed as ROOT user.

@PCW
 I also set the jumpers to TTL and tried it out, but unfortunately the result is the same.
Here are the HAL and INI:
