How is the NGW-1 Powered?
All ISO-Drive variants (NGW-1-ISO, NGW-1-ISO-AIS and NGW-1-STNG) are completely powered from the NMEA 2000 network and have an NMEA 2000 LEN of 1 (50 mA or less). Once connected to a powered and terminated NMEA 2000 network, the NGW-1-ISO LEDs will flash.
All USB variants (NGW-1-USB and NGW-1-USB-AIS) takes most of their power from the USB connection and also have an NMEA 2000 LEN of 1 (50 mA or less). The LEDs will not flash until the USB drivers have been successfully installed (allowing the OS to enable USB power).
