  • Page 8: Introduction

    SeaGauge-Remote G2 User’s Manual Introduction Welcome Thank you for purchasing a Chetco Digital Instruments product. SeaGauge-Remote™ provides custom instrumentation in a rugged compact design. Its user defined calibration tables and alarms allow it adapt to and monitor many different sensors from a single location.

  • Page 9: Analog Inputs

    SeaGauge-Remote G2 User’s Manual Analog Inputs – SeaGauge-Remote will support up to 12 analog inputs for interface to most temperature, pressure, and voltage senders. Internal signal conditioning allows resistive senders and direct voltage inputs up to 36 volts on selected inputs. Most temperature and pressure senders use variable resistance to convert physical parameters into an analog voltage.

  • Page 11: What You Get

    SeaGauge-Remote G2 User’s Manual What You Get Unit SeaGauge-Remote unit with power and sensor input. Unit constantly monitors the sensor inputs and creates NMEA 0183 compatible sentences two times per second. A 10-bit analog converter samples sensor data and then performs a real-time average. The built-in microprocessor takes the averaged value for each sensor and looks up the display value from a 256 point table that is user modifiable.

  • Page 13: Operation

    SeaGauge-Remote G2 User’s Manual Operation SeaGauge-Remote is sealed and self-contained. All user control is performed via the built-in USB or RS232 ports. The unit can be configured with the included vDash utility described in a separate manual or via text commands sent directly to the serial port. When you receive your unit it has been programmed with default sensor calibration tables and labels.
  • Page 14 SeaGauge-Remote G2 User’s Manual Data Output format After the unit is properly installed and powered up, it will automatically start transmitting data in NMEA 0183 format with an update rate of 1 per second for each of 16 inputs (12 analog and 3 pulse).

  • Page 15: Display Label Table

    SeaGauge-Remote G2 User’s Manual Display Label Table The display labels are obtained from a lookup table. An example table is sown as follows: [TABLE][6800][8][64] db 'P TEMP ' ; 0 db 'S TEMP ' ; 1 db 'P FUEL ' ; 2 db 'S FUEL ' ;...

  • Page 16: Channels Table

    SeaGauge-Remote G2 User’s Manual Channels Table The 12 sensor input are assigned to calibration tables via the Channels Table. This table allows mapping of analog inputs to desired lookup tables. Calibration tables are assigned in the same order as the Display Label Table entries. So for example – the OIL label is assigned to the first calibration table and the ENGINE the second and so on.
  • Page 17 SeaGauge-Remote G2 User’s Manual Alarms Tables The Alarms table is used to set min and max alarm thresholds for each of the 8 sensor inputs. After the analog conversion and digital averaging, the 10 bit vales are scaled to 8-bit values and used to perform a lookup of actual display values from the Calibration tables.
  • Page 18 SeaGauge-Remote G2 User’s Manual Alarm values are entered in pairs with the first value being the min alarm threshold and the second being the max threshold. If the min threshold is set to %00, then the min alarm is disabled since no sensor value can be less then 0. If the max threshold is set to %FF, then the max alarm is disabled since no sensor value can be greater then 255.

  • Page 19: Calibration Tables

    SeaGauge-Remote G2 User’s Manual Calibration Tables The SeaGauge-Remote contains 12 calibration tables used to convert sensor input to display values. Sensor inputs are averaged, scaled, and converted to digital values with a range from 0 to 255 decimal. These values are then used to look up 8 character values from a 256 row calibration table.
  • Page 20 SeaGauge-Remote G2 User’s Manual • Column 14 – is a comment and usually is the table row index number for reference The 4 character display value can be any alpha-numeric value but usually is a numeric sequence representing the desired readout for the given table index. The 2 character HEX NMEA 2000 Display Lookup value is used to calibrate the data used to generate NMEA 2000 PGNs.
