For logging the water depth, users need a black box for doing this...

There are several systems of navigation instruments on board:

1. NMEA-0183 with single GPS and single sounder
2. NMEA-0183 export from a chart plotter, with connected GPS and sounder
3. SeaTalk-1 with connected GPS and sounder
4. NMEA-2000 with connected GPS and sounder
5. Chart plotters writing to an SD-card, (W)LAN or USB, with connected GPS and sounder

We need two HW-Loggers:

NMEA-0183/SeaTalk-1
NMEA-2000

Skipper with PC and NMEA-0183 can use our SW-Logger (plus RS-232>USB converter).

NMEA-0183 HW-Logger

Nr what for Connector Remarks
2 NMEA-0183 input screw terminal 2-channel, opto coupler
1 channel switchable to Seatalk-1
1 SD-card output slot
1 12 V power screw terminal 5..30 V? <100 mA
1 Accelerometer internal Roll and pitch
1 Pulse generator internal Time stamping the sounder- and accelerometer data
1 Battery internal Buffering power interruption. Goldcap?
2 LED operation indicator Power, data on channel A, data on channel B
Processing
Listening to the two ports and the accelerometer
Time stamping the sounder- and accelerometer data by GPS-time plus pulse generator
Filtering/processing the accelerometer data (too much data)
Merging the data
Writing the merged data continuously into a file to the SD-chard
Starting new files (each day?)
Handling of powerdown (closing the file)
Body
Standard (no IPx)
Mountable by 2 screws on wood
3x2 screw terminal, 1x SD-Card-slot
3 LED

NMEA-2000 HW-Logger

Nr what for Connector Remarks
1 NMEA-2000 input MicroC opto coupler

Alternatives: OLinuXino, BeagleBone

Features:

Mechanical

   PCB to mount on GPIO pin connector of the Raspberry Pi
   Mounting holes for spacers over mounting hole on RasPi
   Enclosures for accommodating Raspberry Pi + sensor board, cables, etc
   Protection class IP.., heat dissipation (3W) should be possible by surface convection
   Strain relief for connection cables, screw terminals
   Solder connection for SeaTalk / NMEA cable to the sensor module
   Pin connector with loop through GPIO contacts
   Nice to have: Compatibility with existing modules

Electrical

   Power supply ??
   Opto-isolated RS-422 NMEA-0183 interface power supply
   Opto-isolated SeaTalk-1 interface with collision detection, Host
   RGB-LED(s) and 3 GPIO-Pins
   Sensor-Board:
     SPI or I2C bus, if possible - SW-Driver??
     Air pressure sensor
     Temperature Sensor
