LED Indicators

The A840 Telemetry Gateway has five LED indicators on its panel.

The indicators have a different significance based on whether the device is operating in the usual Linux mode or in hermit mode (for upgrading software and in other unusual circumstances).

“Advanced Functions” on page 17 provides more details about the operating modes.

Linux Mode

If this is a new installation, you need to install the RTUs in the field and configure them in addVANTAGE. Refer to the addVANTAGE software and respective RTU user manuals for additional details.

LAN and ACT

These two LEDs are active only if you have a network cable attached to the gateway and the network section is enabled. In addition, the mains (110/220 volt) must be present, that is, the gateway must not run on its internal batteries. The LAN LED is lit while the ethernet line is operational, and the ACT LED shows activity on the ethernet line.

Note: Although most of the network functionality is already built into your gateway, it is not enabled by default. You must contact Adcon or your distributor if you want to enable networking in your gateway.

USR and RUN

The USR LED lights when communication takes place over the RS-

485 line, that is, to or from the A440 Wireless Modem unit. The

RUN LED is currently not used in Linux mode.
