I have a 7i95 that I plan to use with the 7i70 and 7i71. But I also have the 25 pins port on the 7i95 so it would be possible to use the 7i89 with that firmware just for counting right?
If thats a plain 7I95, it will not fit. It will fit in a 7I95T (all encoders 6 on the 7I95T and 24 on the 7I89) El vie, 6 dic 2024 a las 11:55, Peter Wallace (<p...@mesanet.com>) escribi??:

I could use a 7i80DB (I'm not sure >the 7i92 can be connected to the 7i89) to interface with the 7i89. A regular (non-T) 7I92 may be too small to fit all 24 counters But I can see what fits. What 7I80DB model do you have? (-16 or -25) Is there a firmware already available for the A input only encoders? Generally, yes. Specificall for the 7I89, no What other I/O do you need in the configuration?
