where:
— Vp [V]: pull-up voltage
—R [k]: pull-up resistance
For the typical pull-up resistor values, refer to Table E-14 on page 478.
Step 11. Set up the bit switch for input signals as instructed in Table E-13.
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.
The typical pull-up resistor values are:

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).
