Understanding CBL Commands
What are CBL Commands?
Commands are sent to the CBL as a list. A command number is always
the first integer in the list. CBL command numbers are single-digit
integers that represent operations as shown in the table below. There are
eight commands that are used to control the CBL.
Command Function
0*
All Clear:
CMD0
resets all channels to default conditions
(page 27).
1*
Channel Setup:
CMD1
sets up a channel for data
collection (page 28).
2
Data Type and Display Setup:
CMD2
lets you select the
type of data, such as lists, matrices, and pictures that will
be retrieved by a calculator (page 36).
3*
Sample and Trigger Setup:
CMD3
sets up the timing and
trigger parameters for an experiment (page 39).
4
Conversion Equation Setup:
CMD4
sets up parameters
to convert the physical unit measured by CBL into a more
useful measurement unit such as Newtons or °C (page 47).
5
Data Range Setup:
CMD5
selects the type of data to be
retrieved as well as the starting and ending data points to
be retrieved by a calculator (page 49).
6
Multimeter Mode Setup:
CMD6
sets up the
CH1
or
SONIC
channels to measure volts, ohms, meters, feet, and
other multimeter operations (page 52).
7
Request Status:
CMD7
creates a list of CBL status
information for retrieval by a calculator (page 54).
*Note: Clears all previously collected data from the CBL.
