This program is FAST_ACQ.BAS in the \EXAMPLES\ subdirectory. It will configure 48 thermocouple
channels, set up the TempScan/1100 for fast acquisition, and then bring the values into the controller after
the acquisition is complete. From a logic standpoint, the difference between this program and the
SLOW_ACQ.BAS program is that this FAST_ACQ.BAS program reads blocks of data instead of one scan at a
time. This method is usually more efficient in case of fast scan intervals.
