Are the glass scales differential out or single ended?

The 7I76 encoder input needs to be jumpered to match the encoder type

Output Signal: EIA-422
The glas scales works fine, no problems on 7i85

if you jumper the 7I76 for TTL/single ended mode,
you can test each input by simply grounding each
encoder+ input (TB3 pins 7,10,13 = A,B,IDX) and
watching them in halshow.

W4, W5, W6 are in the right hand position. Mode is differential.

For testing the individual inputs, setting them to single ended mode
allows you to test each signal by simply grounding the A+,B+,IDX+
inputs

Um jetzt mal eine kurze Rückmeldung zu geben, ich gebe das auf mit dem Encoder vom Servo, weil dort einfach keine Signale rauskommen, es ist wohl die Version, welche diese Ausgänge nicht hat.
Ich habe mir einen günstigen Drehgeber bestellt mit differentiellen Ausgängen so wie die Glasmaßstäbe das auch haben.
Rückmeldung wird folgen, sobald ich den Encoder hier habe.
Danke nochmals für eure Unterstützung

To give you a short feedback, I'm giving up on the encoder from the servo because there are simply no signals coming out, it's probably the version that doesn't have these outputs.
I have ordered a cheap encoder with differential outputs like the glass scales have.
Feedback will follow as soon as I have the encoder here.
Thanks again for your support

So, ich habe mir mal einen normalen Drehencoder besorgt und den an die 7i76 angeschlossen. Dort wechselt "Count" nur zwischen 0 und -1, "B" blinkt wenn ich den Encoder drehe und "A" leuchtet konstant in der HAL Show. "Velocity" und "Raw Counts" tut sich gar nicht. Stecke ich nun um auf die 7i85 (Ausgang 02), dann funktioniert alles wie es soll, "RAW Counts" und "Counts" werden gezählt, ein Wechsel zwischen "A" und "B", also alles so wie es sein soll. Keine Ahnung, warum das so ist. Jetzt warte ich noch auf 2 GT2 Riemenräder und den Zahnriemen, dann kann ich das Ganze mit Motor testen, ob es dann mit dem Gewinde funktioniert.

So, I got myself a normal rotary encoder and connected it to the 7i76. There “Count” only changes between 0 and -1, “B” flashes when I turn the encoder and “A” lights up constantly in the HAL show. “Velocity” and ‘Raw Counts’ do not change at all. If I now switch to the 7i85 (output 02), everything works as it should, “RAW Counts” and “Counts” are counted, a change between “A” and “B”, so everything is as it should be. No idea why this is the case. Now I'm waiting for 2 GT2 pulleys and the timing belt, then I can test the whole thing with the motor to see if it works with the thread.
