Control Methods - Klein 3000 Series Operation And Maintenance Manual

APPENDIX B: TPU S
This appendix describes the various control and initialization procedures for the
3000, 5000 and 5900 Sonar System TPUs. The information in this document
applies to TPU software version 5.3 and later.
B.1 Control Methods
Aside from control of the TPU via the Ethernet interface, the 3000/5000/5900
System may be controlled via NMEA messages or via a startup script file. This
document outlines these latter two control methods.
B.2 Startup Script
The TPU defaults to various values for its adjustable parameters. If these default
values are unsatisfactory then a startup script may be included to override the
default values. This script is executed at boot up if the path to the file is included in
the startup script field of the boot parameters. (See "TPU LAN Configuration
Setup" on page C-5.) The syntax is "set <VARIABLE> <VALUE>" where
<VARIABLE> is one of the variables from the list below and the values are as
defined for the associated commands. If a variable is not included in the file, then
the default value is used. The following variables are available:
3.1 RANGE {d = 0,1,2,3; or 25 - 1500}. Set range scale, where d = 0 is 50
m, d = 1 is 75 m, d = 2 is 100 m and d = 3 is 150 m. Default = 100 m. For the
5000 System the above enumerated ranges are available. For both the 3000
System and 5000 System the range scale may be set by simply specifying the
range in meters, i.e. set RANGE 150, which would set the range scale to 150
meters. For the System 5900 the range scale may be set to any value between
150 and 1500 meters.
The 3000 System does not support waveform initialization via the startup
script. Either the default waveform must be used or the Ethernet interface used
to control the waveform.
RESPDIV {d = 0 - 15}. Sets the responder divisor to 2^d, where d = 0 – 15. A
value of 15 turns the responder off. Default is 15 (off).
RESPFREQ {d = 0 - 15}. Sets the responder frequency to 24 kHz + d * 500
Hz, where d = 0 – 15. Default is 7 (27.5 kHz).
DESPECKLESWITCH {d = 0,1,2,3}. Set despeckle mode, where d = 0 is
