KDC Series II DC Power Supplies 103
9.2 KDCGUI Program Requirements
To successfully install and operate the KDCGUI program, you will need the following equipment:
Argantix KDC Series DC power supply.
PC capable of running Windows 98™ , Windows 2000 or Windows XP
RS232C communications port
RS232C serial cable (supplied with the product.)
or
If option -IF (GPIB) is installed, a National Instruments IEEE-488 Controller Card
Note: The KDCGUI can be run in the absence of a DC power supply. If no DC supply is
available, the KDCGUI can be operated in a simulation mode. The program will
detect these conditions and start up in simulation mode after notifying the
operator. Measurements in this case will be simulated and should not be used for
any analytical purpose.
9.3 RS232C Interface
A suitable cable to connect the power supply to a 9 pin PC-AT style serial port is supplied with
the power supply.
The KDC Series expects a LF (Hex 10) terminator at the end of each string sent over the
RS232C interface. If the programming environment you use to develop test programs does not
append a LF terminator to each output string, the KDC Series will not respond. This may be the
case for
programs like LabView™ using VISA drivers.
9.3.1 Serial Communication Test Program
The following sample program written in Quick-BASIC can be used to check communication to
the KDC Series Power supply over the RS232C serial interface. The interface is optional and
must be installed for this to work.
