This program is
HLL32.BAS
in the
\EXAMPLES\
subdirectory. It will configure 32 channels, collect the
High/Low/Last (HLL) Registers data, and post it on the screen.
• Lines 1- 3: Although not necessary, it is good practice to reset the TempScan/1100 at the start of your
application by sending the Reset Power-On (
*R
) command. Wait few seconds.
• Lines 4-7: To be certain that the reset was successful and the device is ready, Serial Poll the device
until the proper status is returned.
• Line 8: The Configure Channels (
C
) command will be used to configure a range of channels from 1 to
32 as Type T thermocouples.
• Lines 9-10: Program for one Pre-Trigger scan via the Set Counts (
Y
) command. Then program the
Trigger (trigger start event) and Stop (trigger stop event) via the Set Trigger Configuration (
T
)
command to arm the acquisition.
• Lines 11-13: The next three lines tell you to hit a key to start the acquisition. The program will not
proceed until a key is pressed.
• Lines 14-22: Until another key is pressed to exit the loop, the
U4
command is issued and the HLL data
is collected. The IEEE 488 controller command
OUTPUT
sends
U4
to the TempScan/1100, the
command
ENTER
requests the data, then the command
LINE INPUT
gets the data from the IEEE 488
driver and places it in the variable
U$
. The
FOR
loop extracts the data for the individual channels from
the string
U$
and places them on the screen. Time and date information is also available in the HLL
data.
