Field Installation
Note:
The LED tool is a blind plug to be plugged into the POWER connector.
Follow these steps to install an A73x RTU in the field:
1. Review the installation area and choose the best site (for the A733GSM/GPRS
2. Perform a connectivity check using the LED tool:
Note:
For the A733GSM/GPRS, make sure that you have a sufficient RF signal from your
cellular service provider. The simplest way to achieve this is to check a cellular
phone operated by the same cellular service provider on the site where you want to
install the RTU.
3. Assemble your pole set.
4. Put an Adcon plastic cap into the top of the pole and secure it with a pie clamp
5. Using a hammer, drive the 80 cm aluminum rod into the ground.
6. Using the pipe clamp supplied, fasten the solar panel onto the pole. Make sure
Note:
The solar panel can be mounted under or behind the A73x RTU, but make sure
that the RTU does not shadow the panel.
7. Fasten the A73x RTU to the top of the pole with a pipe clamp. Adcon

This completes the installation of your A73x RTU. If one of the I/O connectors is left
unused, use the cap specially provided to protect it against moisture and dust. Be
sure to make a note of the following information because you'll need it when you

Insert the LED tool into 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 several more seconds, the LED
will blink one or more times (the number of blinks indicates the number
of stations it has successfully contacted).
