Internal pull-up/pull-down capability

Each of the eight DIO bits on the USB-2416 has a 47 kΩ pull-up/pull-down resistor. To configure these bits for

the 0 V pull-down option, you must open the USB-2416 case to access the three-pin jumper labeled JP1.

To open the case and set the JP1 jumper, do the following.

1. Turn over the USB-2416 and rest it on its top on a flat, stable surface.

2. Remove the five screws shown in Figure 14 from the bottom of the module.

3. Holding both the top and bottom sections of the module, turn it over, rest it on the surface, and carefully

remove the top portion of the case.
