4. Advanced configuration commands
4.1 YD:CALIBRATION <A..D> [p4,p8,...,p95|OFF]
Where: p4,p8,…,p95 — 12 calibration points (decimal values, 0..100)
Resistive fuel level sensors do not take the shape of the fuel tank into account; therefore, the readings
usually have substantial error. The same issue is applicable to the voltage-output sensors which do not have
an internal calibration mechanism, neither do they have a non-linear output.
This setting defines 12 calibration points for 4, 8, 12, 20, 30, 40, 50, 60, 70, 80, 90 and 95% readings
(assuming that 0% and 100% readings do not require calibration). For each point, you should specify the
correct display value.
For example, if your fuel gauge shows 50% when the tank actually is only 19% full, then you should set 19
as the value for the 50% calibration point (7th value in the calibration string). To simplify obtaining the
calibration string, we prepared an Excel file available on our web site. You only need to specify your gauge's
readings and the measured remaining fuel volume to get the calculated calibration string.
4.2 YD:CUSTOM_DATA <A..D> [OFF | 0..9]
Where: the number in the last parameter is Garmin «Custom Channel» number.
Disables/enables Garmin «Custom Channels» mode. In this mode, the Device starts transmitting the
measured value as an percent type value (with name YDTA) for the specified «Custom Channel» number
with 500ms interval along with «Fluid Level» PGN 127505 for specified channel. This mode can be used
only with compatible Garmin NMEA 2000 equipment.
4.3 YD:JOIN [[A][B][C][D] | NONE]
Turns on/off transmission of PGN 127496 “Trip Fuel Consumption, Vessel” with “Estimated Fuel
Remaining” field filled by the sum of fuel volume in selected tanks. The CAPACITY (see 2.3 in this section)
for selected tanks must be configured.
