Handler Interface
Setting Up the Handler Interface Board
where:
— Vp [V]: pull-up voltage
— R [k]: pull-up resistance
For the typical pull-up resistor values, refer to
Step 11. Set up the bit switch for input signals as instructed in

Step 12. Connect the flat cable to the handler interface board. Reinstall the handler
interface board to its original position and secure it with the two screws.
When tightening each screw, take care not to apply excessive force
because doing so can break the tapped hole. (0.98 N-Em, 0.1 kgf-m Max).
The typical pull-up resistor values are:
