Whats a RS422? I Never used that!
I appreciate that this stuff take us way outside our comfort zone. But by using a digital switch that can count to 4 in binary saves pins. eg. We get 4 states out of 4 pins.... That was my big discovery, Re read my tutorial

oops I missed a couple f replys. Now I'm confused!
I never used any resistors.

Haha i was also confused when i have read your first post on this page 
Current situation: The wiring is done as shown on this manual (page: Connection of MPG's): wiki.eusurplus.com/downloads/7i76E.pdf
Now i would like to make the setup for the MPG with the PCCONF tool: I am on the configuration page on the main Tab "7i76 I/O (SS 0)" and the daughter tab "7i76-I/O TB5". There os jabe to chose the function. I choosed "Jog X +" for Input 16 and "Jog X -" for Input 17, which is for sure wrong, because nothing happend on the AXIS GUI DRO, but the MPG gives 5v when turning the handwheel.

No problem, but for me it actually does not matter how to set it up, i would just like to get it work, so if you have a idea what i have to change in the .HAL, then please let me know. Maybe i will then learn a bit and understand it to get other things done.

In this old #130396 is a tar.
It is based on gmoccapy
In that there are a lot of hals. If i remember right one is called mpg...

@Rod, you mean 2 pins,
@Danhen, you are not using two power supplies , so you are good and the wiring should be ok if those are +5V and gnd from the Mesa with the red and black wire.
@Rod, those are pull up resistor as the encoder has open collector outputs, so it can pull the signal to ground but not to +5V.
@Danhen, in pncconf, there is the option of using MPG, but i think it is for the spindle encoder, so you can set that and later edit the hal to point them to the actual encoders.

Thanks Mikel_Eitel and tommylight.
Sorry for my lathe reply, but unfortunately (as always with Linux) i had and still have problems with my wifi on the test pc. Its disconnecting from time to time when using a brower. But it does not matter right now.
To Mikel_Eitel: I cant find that post: #130396. Could you send me the link?
To tommylight: thanks, but its impossible to get it done for me, because i just dont know what i am doing or what i have to do. Its so complicated for me and i really dont know why. The CNC router with the cheap BOB was so easy to set up, but i really dont know how to do that with the mpg handwheels.
I try to check some settings from others, but the first thing which i just dont understand is, why in no lines in the HAL are the input pines pointed out.
Like for example i found this answer from Andypugh on that topic Mesa 5i25 and 7176 getting started :
Are there no input pins missing? I just dont get it. No even a bit. I would really wish someone would make a tutorial or something and not just give 10% info. At least i think that its impossible to know what to do for a "mesa beginner" as i am.
Here one more example of a HAL file to explain you what i dont understand (it was for a 3 axis mpg pendant i think) from this topic: 5i25 7i76 mpg help please
He did connect the MPG to TB5 Pin 1 and Pin 2, as i did also for one MPG handwheel. But no where in the HAL i can find something like "input 16" and "input 17".
Guys, i dont wanna cry, but i dont get it done by my self. No chance. I know that this is not your problem and you are helping here for free, but since i have got the Mesa 7i76e i have spend about 24 hours to get things done and from the 24h a spend at least 10 hours, just to get the Handwheels connected and setup, but with no positive result. I am currently really thinking to give up and sell the 7i76e, forget about the mpg handwheels and just use a cheap BOB which i know that i will be able to setup.
Another option is that someone does the work for me and i pay for that. There are nicer things to do then trying something without any clue about it.

Then connect the mpg to each axis:
net x-jog hm2_5i25.0.7i76.0.0.enc0.count => axis.0.jog-counts
net z-jog hm2_5i25.0.7i76.0.0.enc1.count => axis.2.jog-counts

net tool-change-confirmed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-preparedHe did connect the MPG to TB5 Pin 1 and Pin 2, as i did also for one MPG handwheel. But no where in the HAL i can find something like "input 16" and "input 17".
Guys, i dont wanna cry, but i dont get it done by my self. No chance. I know that this is not your problem and you are helping here for free, but since i have got the Mesa 7i76e i have spend about 24 hours to get things done and from the 24h a spend at least 10 hours, just to get the Handwheels connected and setup, but with no positive result. I am currently really thinking to give up and sell the 7i76e, forget about the mpg handwheels and just use a cheap BOB which i know that i will be able to setup.
Another option is that someone does the work for me and i pay for that. There are nicer things to do then trying something without any clue about it.

Just copied my mpg.hal completely as i do not know how to make those foldable

Take a break for tonight, go out and forget about all this here.
Tomorrow is Sunday, so grab a coffee and a smoke and a chair, we'll give it a go at a slower pace.
