ETHERNET LINK LED
The
Ethernet Link
LED illuminates (green) if the Ethernet is connected. When the LED is blinking it indicates that
there is data traffic on the Ethernet link.
E1 is used to connect to the network.
READY LED
The
Ready
LED (green) blinks if the system is operating correctly, once per second in normal operating conditions,
or three times per second in reset, configuration mode, or when loading factory defaults. If the LED is off or steady,
it indicates the system is not operating correctly.
SERIAL PORT LEDS
ESERV-M12T Modbus Gateways feature two serial ports. Each serial port has an associated LED. Serial Port LEDs
blink (green) when data is being transmitted or received on the serial port. When the LED is On, it indicates the
serial port is open.
