LED indicators
RS-485 communication status (yellow LED)
LED flashes
A message is received by the WirelessHART gateway via the serial interface.
The LED does not flash if the message is not addressed to the WirelessHART
gateway or if a communication error was detected within the message.
LED off
No serial communication at present.
Power supply (green LED)
LED on
Power connected. The WirelessHART gateway ready.
LED flashes
Power connected, but the WirelessHART gateway is not yet ready to send

events and notifications).
LED off
No wireless communication at present.
Fault (red LED)
LED on
Hardware fault which makes normal operation of the WirelessHART gateway
impossible.
LED flashes
Under certain conditions the LED flashes while the WirelessHART gateway
application tries to eliminate the fault.
LED off
No hardware fault.
Ethernet communication status (yellow LED)
LED flashes
A message is received by the WirelessHART gateway via the Ethernet
