4 Menu system
The menu system, controlled via a remote indicator i.e. the Speed Log
Master Display, enables controls and user interaction of the SAL T-series
log. The communication commands are described below. Keys available
are “MENU”, “ENTER”, “+” and “-”.
4.1 Normal operation
The log in normal operation calculates the speed from the sensor signals.
When a new measurement value is available, it may be shown on the
remote indicator. In normal operation within depth range the readout
mainly uses the following field descriptors:
BTL±xx.xxT±yy.yy
DT ddd.ddS±sss.s
The definition for the field descriptors is found in the table below.
Descriptor Explanation
±xx.xx / --.--
Sensed longitudinal speed in knots from transducer.
Field is --.-- if no valid speed is available.
±yy.yy / --.--
Sensed transversal speed in knots from transducer.
Field is --.-- if no valid speed is available.
±ddd.dd / --.-
Sensed depth below transducer.
Field is --.-- if no valid depth is available.
±sss.s / --.-
Sensed signal strength in dB from transducer.
Field is --.-- if no valid signal is available.
4.2 Menu settings
The menus for parameters and internal settings have a two digit
alphanumeric field Aa to the left followed by a menu name or
abbreviation on the first line on the Speed Log Master Display.
The second line is reserved for value or parameter setting. The readout
thus looks like:
