7.4 Command Format
All operator commands start with a three character command code (mnemonic)
indicating the parameter to be monitored or changed. See Section 7.7 for a full list of
commands.
This mnemonic is normally an abbreviation of the associated parameter making them
easier to remember, for example, entering the mnemonic ‘DOS’ displays the Detector
Output Status on the User Terminal.
Following the mnemonic may be one or two indexes before the required information is
displayed.
For example;
SPT
After the mnemonic and the indexes (if any), the detector will display the current value
of the parameter. A colon ‘:’ is used to separate this from the mnemonic and indexes.
Therefore, to view the current value of the Detector Speed Threshold the following
command would be entered and then the result would be displayed:

SPT SPT:50
i.e. Speed Threshold is 50 km/h
To modify the value, the full command can be entered followed by an equal sign ‘=‘ and
the new value required.
Note: Write access may need to be entered first before data can be modified; see page
84, and most commands have configurable range limits to limit the range of values that
can be entered.
