This program is HLL48.BAS in the \EXAMPLES\ subdirectory. It will configure 24 thermocouple and 24
volts 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 MultiScan/1200 at the start of your
application by sending the Reset Power-On ( *R ) command. Wait a 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.
• Lines 8-9: The first thing necessary to start scanning is to setup the measuring mode. In this case, the
MultiScan/1200 will be setup for line-cycle integration / high-speed multi-channel mode.
• Lines 10-11: The Configure Channels (
C ) command will be used once to configure a range of
channels from 1 to 24 as Type T thermocouples, and used again to configure a range of channels from
25 to 48 as
±10 volts DC inputs.
• Lines 12-13: 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. Telling the MultiScan/1200 to start acquiring data is the last thing
necessary to start scanning. Since the MultiScan/1200 does not scan channels until an acquisition is
armed, arming an acquisition with one Pre-Trigger scan allows valid HLL data to be read.
• Lines 14-16: The next three lines tell you to hit a key to start the acquisition. The program will not
proceed until a key is pressed.
