this work for you. See Section 4, Quickstart, for a Short Cut tutorial.

7.2 Device Configuration Utility

The Device Configuration Utility is used to change settings, set up the analog

Use the OBS500 test cable to connect the OBS500 to a computer running

Device Configuration Utility. The red wire is connected to a 12 Vdc power

supply and the black to ground. The datalogger power supply is a good choice

to use for the power supply. Device Configuration Utility software is shipped

on the Campbell Scientific ResourceDVD included with the OBS500.

The OBS500 is supported in our Device Configuration Utility

version 1.16 or higher.
