Description
Vx x The Voltage Set command sets the
analog output to “Host”, where the
response “x” is a number from 0 to
11000 that equals the desired
voltage in millivolts. See Chapter 4,
“Configuring the CPC.”
Wdisplay OK Write a message to be displayed on

BASIC Program: TSICPC
The following BASIC program, which runs only on IBM personal
computers or IBM-compatibles, demonstrates how the computer
interfaces with the CPC using the commands described above. The
program can be used to read concentration and total counts over
regular preset time intervals. The data can be stored on disk or
printed on a printer. A computer is not necessary for normal
operation of the CPC.
