Introduction
Digital I/O Module
IOLANs that have Digital I/O have an input/output jumper that must be set for each channel and must 
match the software configuration for each channel. Depending on the model, the placement of the 
digital I/O board can change, so the diagram below shows how to set jumper for any digital board.To 
change the settings, do the following:
1.
Detach the IOLAN from the electrical power source and disconnect everything from the box.
2.
Open the case by unscrewing the five side screws, two on each side plus the grounding screw, 
and lifting off the top of the case. You should see the following configuration for the digital I/O 
board: 
3.
To turn line termination 
on
, locate and jumper J8 for Half Duplex Rx/Tx.
4.
To configure either Channel 1 or Channel 3 (depending on how many Digital channels your I/O 
supports and following the mylar channel definitions) for Input, jumper J3 pin 1 and 2 (as 
shown); this is the default setting. To configure either Channel 2 or Channel 4 (depending on 
how many Digital channels your I/O supports and following the mylar channel definitions) for 
Output, jumper J5 pin 2 and 3 (as shown).
5.
Close the IOLAN case by replacing the case lid and the five screws. You can now power it on 
with the new settings. 
Analog Input Module
IOLANs that have Analog Input have a voltage/current jumper that must be set for each channel and 
must match the software configuration for each channel. To change the settings, do the following:
1.
Detach the IOLAN from the electrical power source and disconnect everything from the box.
Note:
Jumper pins 1 and 2 for Input. Jumper pins 2 and 3 for Output.
