Designed specifically for outboards without digital interfaces, this gateway provides SeaTalkNG devices devices with engine speed (RPM), alternator voltage (measured at the SeaTalkNG interface) and engine hours. It can also be programmed to use data from SeaTalkNG temperature or pressure sensors and send these data as coolant and oil pressure or temperature, boost or fuel pressure. You can also programme the device to issue high revolutions, high temperature and low voltage warnings, and set the state of the charge indicator (displayed on MFD or SeaTalkNG display).
If your boat has a single battery, the low voltage alert can keep things from getting to the point where your engine's voltage regulator or alternator gives out when the battery is almost dead. In the settings, you can connect external SeaTalkNG thermometers and pressure sensors to the gateway, configure and set threshold values for alarms and warnings (high engine speed, high temperature, low voltage). The firmware can be updated using the free CAN Log Viewer software (works under Microsoft Windows, Linux and MacOS X). To configure other settings, you will need a PC gateway and software.
CONNECTION:
All that is required to connect the Gateway is to connect it to the SeaTalkNG backbone, wrap its wire around the spark plug wire four or five times, and tape the loops in place. Most of the time, there are no extra settings needed, however depending on your engine type and ignition system, you may need to adjust the RPM divider.
If your outboard engine is big enough, the device can be placed inside the engine. Ensure that it is firmly attached, well-ventilated, kept away from heat sources, and shielded from any potential sprays of petrol, oil, or water. You can install the Outboard Gateway and SeaTalkNG Wi-Fi Gateway inside the motor and power them from the ignition if you're having trouble routing the SeaTalkNG cable to the motor. A concealed button on the Gateway allows you to reset the device's settings, change the engine number (0–3), and adjust the RPM divider (0.5–8). To install the device, just these settings are required. The 4-stroke and 2-stroke engine types as well as the kind of ignition system you have will determine the value of the RPM divider (1 is the factory setting). Most modern 2-stroke engines need a divider of 0.5 (multiply on 2) for counted pulses, and most 4-stroke engines need a divider of 1 (the number of sparks is equal to the number of revolutions).
To check the signal, the device has an LED that emits a sequence of four two-colour flashes every five seconds. The colour of the first flash of a sequence indicates whether the device has a signal at all (with at least 50 % amplitude); and the colour of the second flash indicates whether the signal is of good quality (over 60 %). The Outboard Gateway is supplied with a Raymarine SeaTalk NG connector. An adapter cable may be required for other networks.
