SmartLog NMEA0183 USB Logger
Easy logging of your instrument data into your apps
NMEA0183
The device receives NMEA0183 data, the industry standard for many years, and still output by most newer instruments that use NMEA2000. The NMEA port operates at 4800bps, is fully opto-isolated , and will tolerate inadvertent connections to the boat’s power supply.
Seatalk
With the optional Seatalk adapter, one of the NMEA ports can be converted to support Raymarine’s Seatalk (sometimes referred to as Seatalk 1). The Seatalk data packets are encapsulated in a proprietary NMEA sentence rather than being converted to NMEA0183 in the device, so all Seatalk data packets are supported.
2 Channels
The logger has 2 input channels, e.g. a GPS for position and time data in conjunction with a depth sounder or wind instruments. Data from the two channels is merged into a single output file, with no changes or additions to the incoming data.
USB
Data is logged to a standard USB memory stick (formatted as FAT or FAT32). 1MB of storage can hold about 35 500 NMEA sentences, or 45 minutes of data, depending on the output of the instruments.
Power
Designed for boats in mind, it will run off a 12V or 24V DC supply, and tolerate voltages from 9 to 30V. Power consumpotion is approx. 0.11A @ 12V DC, depending on your USB memory stick. It has reverse polarity protection, and an internal self-resetting fuse.
Ease of Use
Just plug in and go. It is ready to log data as soon as it is powered up, and all incoming data is automatically logged to a USB memory stick. No configuration required, and no need to download data or mess around with data cards.
