4.2 User interface
4.2.1 LED indicators
There are four LED indicators on the top of each SmartBoat module.
 Power: This orange LED lights to indicate that the module is receiving power
through the primary NMEA 2000 bus connection. In normal operation, it will
remain on. This LED will flash during configuration, diagnostic testing, and during
a low-level firmware update.
 Status:This green LED lights to indicate that the module is operating normally.
When first starting, this LED will flash as diagnostics are performed and the
initialization process is underway. The web configuration interface will be
available when it remains on.
 NMEA 2000: This blue LED will flash when there is NMEA 2000 PGN traffic on either
the primary or secondary physical NMEA buses. A fully configured module will
begin processing NMEA 2000 PGN traffic as soon as possible after power-on.
 Network: This yellow LED will flash when there is web server Wi-Fi or Ethernet traffic
received or sent by the module.

4.2.2 Reset switch
If you forget the password for a SmartBoat module or there is an issue with the Wi-Fi
network configuration that prevents access to the configuration web server, you may
need to reset the configuration of the module. This switch may also be used after a
firmware update to return to the previous firmware version.
On the end of the module enclosure opposite the primary NMEA 2000 bus connector
(above the ethernet connector on an advanced SmartBoat module) is a recessed
switch. It may be used to reset the module. This recessed switch is covered by a small
adhesive label to prevent water ingress.
Figure 4-3 Reset switch location
To reset the system, remove the adhesive label cover. Gently activate the reset switch
by inserting a paper clip or similar implement.
 Reset configuration: Press and hold the reset switch. After approximately 5
seconds, the LEDs will begin to flash. Release the reset switch and the
configuration will be reset to the factory default.
 Restore firmware: Continue to hold the reset switch for an additional 5 seconds
after the LEDs begin flashing. The system will revert to the previous firmware
version. This is only applicable after a firmware update has been performed.
The reset switch is recessed and not visible through the opening. Always press
gently.
Replace the adhesive label after performing the reset to prevent water
ingress.

4.3 Primary NMEA 2000 bus
Each SmartBoat module is attached to the NMEA 2000 bus through a standard drop
cable. This cable must also provide the power to operate the module. Each module
has a bus termination resistor that may be enabled through the user interface. The
interface to the primary NMEA 2000 bus. It is fully isolated according to the NMEA 2000
standard.
4.4 DB-9 connector
Each advanced SmartBoat module has an industry-standard DB-9 connector for access
to a second CAN bus and NMEA 0183 RS-422 serial data. The CAN bus may be
configured as a secondary physical NMEA 2000 bus, an SAE J1939 bus, or used with a
SmartFlex digital sensor.
4.4.1 Pinout and accessory connector
The pinout of this connector is shown below.

Figure 4-4 DB-9 connector pinout
An optional accessory cable is available: Airmar part-number ACC-YCBL-ASM-01. This
cable provides a standard NMEA 2000 connector for attaching the module to a
secondary physical bus, plus wires for NMEA 0183 talker and listener functions. It is
strongly recommended that only an Airmar cable be used to prevent damage to the
SmartBoat module.

Figure 4-5 DB-9 adapter cable: Airmar part-number ACC-YCBL-ASM-01
4.4.2 Secondary NMEA 2000 / SAE J1939 bus / digital sensor interface
Using the DB-9 adapter cable, a SmartBoat module may be attached to a second
NMEA 2000 bus through a standard drop cable. This cable must also provide the power
(LEN 1) to operate the bus interface. An advanced SmartBoat module has a 120 Ωbus
termination resistor for a second NMEA 2000 bus that may be enabled through the user
interface. The interface to the secondary NMEA 2000 bus is fully isolated.
This same interface may be configured for other devices that use the Controller Area
Network (CAN) bus interface for the physical layer. This includes J1939 engine gateway
functions and SmartFlex digital sensors.
4.4.3 NMEA 0183 serial interface
The serial interface follows the TIA/EIA-422 technical standard originated by the
Electronic Industries Alliance that specifies electrical characteristics of a digital signaling
circuit. It provides independent listener (RXD+, RXD-) and talker (TXD+, TXD-) functions
according to the NMEA 0183 standard.

4.5 USB 2.0 ports
There are two USB 2.0 ports. In the current software release, these ports may be used for
a USB storage drive for extended NMEA 2000 bus logging functions only.
4.6 Ethernet port
A standard RJ-45 Ethernet port allows connection to a wired Ethernet network. Network
speeds of 10, 100, or 1000 Mbps are supported.
