Fieldinstallation
Installing a preset RA440 in the field is a fairly simple process. By
performing a connectivity check using an LED tool (not included in the
delivery of a RA440, but available from Adcon), you will be able to
prove connectivity to the A850 gateway.
The LED tool is shown in Figure 8.
Figure 8. LED Tool
Note: The LED tool is a blind plug to be connected to the SOLAR connector.
Follow these steps to install an RA440 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 into the SOLAR connector and wait up to
10 seconds.
Note: The LED tool will light up for several seconds, followed by rapid
flashes. This indicates that the unit has passed to its booting phase.
b. Keep observing the LED tool. The RA440’s blink codes
indicate the unit’s connection state. Table 2.1 describes what
the number of blinks of the RA440 means during connection
to the A850.
