Introduction
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.
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 analog input 
board: 
JP1
JP2
Channel 2
I/O
Channel 1
I/O
Channel 3
Channel 4
JP3
JP4
3.
To configure Channel 1 for Voltage, no jumper should be set (as shown); this is the default 
setting. To configure Channel 2 for Current, jumper both J2 pins (as shown).
4.
Close the IOLAN case by replacing the case lid and the five screws. You can now power it on 
with the new settings.
