The PC-9801 bus correspondence and 2 axis NC control board

---

NC98-2A

---

Characteristic

By changing a port address every substrate, it becomes numerous axis correspondence.




The 24 bit up down counter with the operation input specification which is strong in the noise


ZEN2001P.....2CH
(DC-2MHz Max)





D/A con Bata of 12 bits


AD667.....2CH
(+10V,-10V,+5V,-5V,+2.5V,-2.5V,0 to +10V,0 to +5V Switching's being possible)





The M code correspondence PIO which was isolated with the photo coupler


The I/O total.....32 points
( It contains a special interface allocation ).





It has watch Dog timer and it is a CPU acting selfish without any consideration to others measure.





It does 3 pieces of duty at one sheet as the encoder counter and the D/A con Bata parallel I/O substrate to the thing except the NC controller use.
