Installing the RTU Installing addIT RTUs in the field is a fairly simple process. You’ll
perform a connectivity check with an LED tool (addIT devices don’t
have a built-in LED like the A730MD stations do).
Note: The LED tool is a blind plug to be plugged in the
POWER
connector.
Follow these steps to install an addIT RTU in the field:
1. Review the installation area and choose the best site.
2. Perform a connectivity check using the LED tool:
a. Insert the LED tool in the
POWER
connector and wait up to
10 seconds. If the unit connects to at least one station (or
a base station), it will light up the LED for about 4
seconds.
b. Keep observing the LED tool and, after another several
seconds, the LED will blink one or more times (the
number of blinks indicates the number of stations it has
contacted).
3. Using a hammer, drive the supplied aluminum rod into the
ground. How far you drive the rod into the ground depends
