control the Discharge Power Supply only.
3.2.1 Direct RS-232 connection from computer to discharge
power supply
The Discharge Power Supply can be operated from a host computer using
an RS-232 port on the computer. Connection from the computer is made
from a serial port on the computer to the serial port on the Discharge Power
Supply, labeled, “RS-232”. This approach uses an RS-232 straight through
cable that connects to a DB-9 male connector. This approach allows the user
to control the Discharge Power Supply only.
3.2.1.1 Software
Software control of the Discharge Power Supply can be accomplished
using a variety of methods. Some type of terminal or communications
program, or programming can be used for controlling this unit. Some
examples of programs that can be used are Hyper Terminal provided
with Microsoft® Windows® systems and LabviewTM by National
InstrumentsTM. Consult the user guide for installation and operation of
the software that you plan on using for use of that program.
3.2.2 Communications settings
Operation of the Discharge Power Supply using a Serial connection requires
the following settings within the terminal or communications program:
• Set communications port to available Comm number.
• Baud Rate Selectable = 1200, 2400, 4800, 9600, 19200, 38400, 57600,
and 115,200 Baud. Note: the default value is 9600. Contact KRI® for
other baud rates.
• Data Bits = 8.
• Parity = None.
• Stop Bits = 1.
3.2.3 Commands
The following ascii commands are speci
fi
c for the Discharge Power Supply.
These commands allow the user to adjust the setpoints on the Discharge
Power Supply and monitor the output voltages and currents.
• VAxxxx Sends a Current setpoint to the Discharge Power Supply.
Note: xxxx is a decimal value from 0-4095. VA0 is the minimum or
