OPTION 6: PROFILER SERIAL OUTPUT OF MEAN ALTITUDE
This feature is available in SeaKing surface software V1.51 onwards. It will operate with a Single or
Dual Head Profiler system. At the end of each scan, a Mean Seabed Altitude will be calculated
from the profile and transmitted out of the SCU serial port in the format of a TSS Altitude string.
The 'Mean Seabed' option will become active by enabling command lines within the software
initialisation file on the Surface Control Unit. Edit the C:\Windows\Sonv3so.ini file and move down
to the following section…

;MeanPrfOutput=-1,1,2,0
;Gating=200 ; in mm
To enable the 'Mean Seabed' output option, change the last 2 lines shown above to the following
(i.e. remove the ";" characters)…
MeanPrfOutput=-1,1,2,0
Gating=200 ; in mm
The 4 numbers in the 1
st
line configure the output as follows;
MeanPrfOutput=a,b,c,d
Where;
a = Mean Seabed Output Option Enabled/Disabled.
{Enabled = -1, Disabled = 0}
b = Serial Channel Selection.
{Channel1 = 1, Channel2 = 2, Channel3 = 3}
c = Profiler Head Selection
{Master Only = 0, Slave Only = 1, Both = 2}
d = Output String Format
{TSS Altimeter, Rxx.xx<cr><lf> = 0}
e.g.
MeanPrfOutput=-1,2,0,0 = Enabled, Chan (2), Master Profiler, TSS Altimeter Format
MeanPrfOutput=0,1,1,0 = Disabled, Chan (1), Slave Profiler, TSS Altimeter Format
MeanPrfOutput=0,1,2,0 = Disabled, Chan (1), Both Profilers, TSS Altimeter Format
The following message type codes are supported;
1. TSS Altimeter = 0
