Off Off
1. The Gateway module is not connected to the NMEA 2000 or CAN bus. Check the
connections on both sides accordingly. If the connections are deemed good, the
Gateway module may require replacement.
2. Power is not present at the Gateway CAN 10‑pin harness connector nor at the
NMEA 2000 harness connector.
Blink (connected to NMEA 2000
only)
The circuit has an intermittent connection. Check the NMEA 2000 harness and
connections accordingly.
Blink (connected to NMEA 0183) NMEA light will blink for normal operation. Refer above for CAN light blink.
Gateway Protocol Description
The software is capable of transmitting (TX) information to, and receiving (RX) information from various parameter group
number (PGN) products.
Gateway Modes
Transmit (TX) Receive (RX)
Transmits Mercury data to NMEA 2000 display devices. Receives data from NMEA 2000 to display on Mercury devices.

Alarm data
NMEA 2000 alarm data is limited and will only display
"Check Engine" when an alarm is activated. Refer to the
Mercury SmartCraft Gauges for descriptive fault text.
Diesel engine alarms are not transmitted to NMEA 2000.
