There's
nothing mysterious about setting up the A/D instrumentation module,
although the software requires some experimentation to understand. You
need a Windows PC and should have a crossover ethernet cable handy. The
instruction manual is helpful, as are the following desscriptions, but you will likely need to spend some time to understand how it works.
Hook up a crossover ethernet cable to the EtherTRAK IO module.
Load the SIXNET IO Tool Kit onto your Windows computer and start it:

Click on File->New Project:

And then select "Add new station to the project:"

Select station type to be EtherTRAK I/O (ET-#):

Save the new project (in this example, LDSS.6pj):

Set the general parameters as shown here, substituting the actual serial number for the example here:

Skip the RS485 setup screen:

Specify the IP address and primary protocol:

Set
the analog parameters using the pull-down menus. The menu sets the
voltage ranges for the A/D conversion. We set the unused channels 3 to
8 to
+/-10 Volts range. The Temperature reporting
setting is not important since we are not using thermocouple or RTD
sensors:

Select the device in the Tree Views (upper left panel), then click on the "1" in the main panel on the right:

Load the configuration into the module:

You should see a "loading" message and some reporting in the bottom box.
