3.2 LED Indicators

LEDs provide visual indications of potential problems. The following LEDs are

found on all ProLinx gateways.

3.2.1 Base Module LEDs

LED State Description

Power Off Power is not connected to the power terminals or source is insufficient

to properly power the gateway (minimum required is 800mA at 24 Vdc)

Green Solid Power is connected to the power terminals.

Fault Off Normal operation.

Red Solid A critical error has occurred. Program executable has failed or has

been user-terminated and is no longer running. Press Reset p/b or

cycle power to clear error. If not, use the Debug procedures described

later in this manual.

Cfg Off Normal operation.

Amber Solid The unit is in configuration mode. The configuration file is currently

being downloaded or, after power-up, is being read, the unit is

implementing the configuration values, and initializing the hardware.

This will occur during power cycle, or after pressing the reset button. It

also occurs after a cold/warm boot command is received.

Err Off Normal operation.

Flashing An error condition has been detected and is occurring on one of the

application ports. Check configuration and troubleshoot for

communication errors.

Solid Red This error flag is cleared at the start of each command attempt

(Master/Client) or on each receipt of data (slave/adapter/server); so, if

this condition exists, it indicates a large number of errors are occurring

in the application (due to bad configuration) or on one or more ports

(network communication failures).

3.2.2 Ethernet LED Indicators

LED State Description

Data OFF No activity on the Ethernet port.

GREEN Flash The Ethernet port is actively transmitting or receiving data.

Link OFF No physical network connection is detected. No Ethernet

communication is possible. Check wiring and cables.

GREEN Solid Physical network connection detected. This LED must be ON

solid for Ethernet communication to be possible.
