‘I’ – Define Increment
Syntax:
I
station
,[distance]<>
or
I
station
<> to read back the current increment selection.
Purpose:
This command allows the user to control when data records will be sent to the
host, based on receiver movement. The “distance” selection allows the user to
specify exactly how much movement will be required before data is produced. If
the user enters ‘I
station
<>’, the system outputs the current distance value
selection.
NOTE:
The system should be in continuous output mode in order for
this command to work properly. Definitions of the command parameters are listed
below:
station
the number of the station whose increment is to be changed.
distance
the minimum distance a receiver must move before a data record
is output to the host computer. The units of measure (inches or
centimeters) for the distance value must be consistent with the
current selection of system units.
Relatives:
None.
Default:
The default value is 0.0 inches, which disables the increment feature.
Example:
If the user wants the system to output data each time the receiver on station 1
moves 2” in any axis, the following command should be entered:
I1,2<>
C
The system will now output a data record each time station 1 receiver moves 2” in
any axis.
