APEX and SOLIX Data Box Digital Readouts

The table below displays the basic data box options that are shown in the Standard data bar and the Navigation data bar, as well as the additional data box options for vessel, wind, and engine. The data box options are determined by the installed equipment and the selected sources on the Humminbird or NMEA 2000 network.

 

Label Name Description Data Type
Depth (#) Depth The depth of the water from the transducer or digital depth sensor to the bottom. This measurement includes the depth offset setting. Depth 
DBT Depth Below Transducer The depth of the water below the transducer. This measurement does not include the depth offset setting.  Depth 
Eng Temp (#) Engine Temperature The engine temperature from the engine source. Engine
Eng Volt (1) Engine Voltage The power supplied to the engine source. Engine
RPM Revolutions Per Minute The number of engine revolutions per minute. Engine
Heat Index Heat Index The perceived temperature derived from air temperature and relative humidity. Environment
Temp (#) Water Temperature The detected water temperature. Environment
Temp (Air) Air Temperature The detected air temperature. Environment
Fuel (#) Fuel Level The fuel level of the fuel source.   Fuel
CTS Course to Steer The heading that must be maintained in order to reach the planned destination. Navigation
Dest Wpt ID Next Waypoint The next point (waypoint, route point, Man Overboard point, etc.) that the vessel is navigating towards in a route or other navigation mode. Navigation
Next Turn Next Turn The course of the next route leg with respect to the current heading. Navigation
TTG Time to Go The estimated time required to reach the next waypoint on the route. TTG is calculated using the SOG (Speed Over Ground) and DTG (Distance to Go). Navigation
Brg Bearing The compass direction from the vessel position to the next waypoint or route point.  Navigation 
Brg (End)  Bearing (To End) The compass direction from the vessel position to the final point in a route. Navigation 
Course Course The intended direction of travel measured between the start point and end point. Navigation 
CMG Course Made Good The bearing from your starting position to the present vessel position. The goal is to have CMG and Track equal to the same number.  Navigation 
DMG Distance Made Good The straight line distance actually traveled between the start position to the current vessel position.  Navigation 
DTG Distance to Go The distance between the vessel position and the next waypoint or route point.  Navigation 
ETA Estimated Time of Arrival The estimated time of arrival to the next waypoint on the route. Navigation 
XTE Cross Track Error The straight-line distance of the boat from the intended Track. XTE measures how far the boat is off course. Navigation 
SMG Speed Made Good The distance from the starting waypoint on the route divided by the time elapsed since starting navigation on the route. Speed
SOG Speed Over Ground The measurement of the boat’s progress across a given distance and the speed measurement provided by GPS. SOG is optimal for navigation because accurate destination times can be derived from this measurement. Speed
STW Speed Through Water The measurement of the flow past the boat, which may vary depending on current speed and direction. Speed
VMG Velocity Made Good The speed of travel relative to the next waypoint on the route.  Speed
COG Course Over Ground The current direction the boat is traveling measured in degrees from North. When the COG is equal to Bearing, the boat is said to be on course and will arrive at the destination in the most efficient manner. Vessel
Hdg Heading The direction the boat is pointing, measured in degrees. Due to wind and waves, the boat is often traveling in a slightly different direction than its heading. See Course Over Ground (see COG). Vessel
Odo Odometer The distance traveled. Vessel
Pitch Pitch The rotation angle of the boat from front to back (bow to stern). Vessel
Position (#) GPS The latitude and longitude coordinates of the vessel position based on the GPS receiver installation location. Vessel
Roll Roll The rotation angle of the boat from side to side (port to starboard). Vessel
ROT Rate of Turn The rate at which the boat is turning, measured in degrees per second. Vessel
Alt Altitude The height measurement above sea level. Vessel 
AWA Apparent Wind Angle The direction of wind relative to the bow of the vessel. Wind
AWS Apparent Wind Speed The speed of wind with respect to the speed of the vessel. Wind
TWA True Wind Angle The wind angle detected when the vessel is stationary. Wind
TWS True Wind Speed The wind speed detected when the vessel is stationary. Wind
