Configuring digital I/O output logic
Referring to Figure 4-4 for the digital I/O output logic loca-
tion, perform the following steps to configure J101
1. If mated together, separate the relay card from the con-
nector card by removing the mounting screw and then
pulling the two cards away from each other. Remember
to only handle the cards by the edges and shields to
avoid contamination.
2. Locate J101 on the relay board. Refer to Figure 4-4.
3. Determine if you require positive (high) or negative
(low) logic.
4. Install the plug-in jumper in the appropriate position as
shown in Figure 4-5.

Configuring digital I/O input pull-up
resistance
Referring to Figure 4-4 for digital I/O input pull-up resis-
tance location, perform the following steps to configur
J100:
1. If mated together, separate the relay card from the con-
nector card by removing the mounting screw and then
pulling the two cards away from each other. Remember
to only handle the cards by the edges and shields to
avoid contamination.
2. Locate J100 on the relay board. Refer to Figure 4-4.
3. Determine if you require pull-up (5V) or pull-down
(ground) input logic.
4. Install the plug-in jumper in the appropriate position as
shown in Figure 4-6.
