Simulation PSKP message
Start/stop simulation mode $PSKPSIM,x.x*[CS][CR][LF] where x.x is a simulated depth value.
The proprietary SKIPPER PSKP NMEA message is used to start and stop depth simulation mode. The
message format is $PSKPSIM,x.x*[CS][CR][LF], where x.x is a simulated depth value.
If the depth value is valid (0 - 1600 m), GDS101 will get into simulation mode, where this value is used
for all indications and outputs (analogue, NMEA, bottom pulse). The “synthetic” bottom pulse which is
generated can be observed on the echogram, “Fig. 2.11. Screen 10, Oscilloscope screen.” on page 22. The
label “SIMUL” is blinking in the lower line - to indicate simulation mode. If the depth value is not valid
(greater than the max range of 1600 m, or empty), the simulation mode will be turned off.
