APPENDIX A   IEEE-488 COMMUNICATIONS

DP Series power supplies are available with an optional IEEE-488 (GPIB) interface.  When
specified at time of order, an IEEE-488 interface module is installed to make a second
UART port available for communications.  With two UART ports available, RS232 and
IEEE-488, the one first receiving communications after power on is the port that is
activated.  Once activated, the other UART port cannot be recognized unless there has been
a period of inactivity for 5 minutes.  After this period, a new UART port can be recognized
by sending communications.

An IVI-COM Driver is included with the installation CD and is available for download from
Magna-Power Electronics’ web page.  The driver allows the power supply to communicate
through many different programming languages.  The driver handles the low-level bus
protocols, simplifying automation development.  It supports TCP/IP, GPIB and RS232 using
standard VISA resource descriptors.  For additional documentation and details on using the
IVI-COM driver, see the driver's included help file (MPEIVI.chm).

A.1

IEEE-488 Communications using the Remote Interface Software

Chapter 5.0 describes application of the Remote Interface Software which is shipped with
DP Series power supplies.  This software provides the user with a quick method to operate a
Magna-Power Electronics’ power supply under computer control.  The software can be
configured for a number of communication interfaces; IEEE-488 is included as one of these
interfaces.

To use the Remote Interface Software with optional IEEE-488 communications, the address,
1 to 30, defined in the Remote Interface Software and the address encoded in the power
supply must match.  Address 0 is normally assigned to the GPIB master The default address
is 1, but if the address is unknown, press Find Device in the Communication Setup menu. 
The routine scans all the devices on the bus providing their addresses and identifications. 
Select the desired device and press OK; this automatically changes the address in the
Communication Setup.  The same result can be achieved with a double click on the desired
device.  After communications is established, the address of the device may be changed by
pressing Change Device’s Settings. 

A.2

IEEE-488 Communications with MAX

National Instruments offers Measurement and Automation Explorer (MAX), a Graphical
User Interface, as a terminal emulation program for configuring an Interchangeable Virtual
Instrument (IVI).  MAX is usually installed with one of National Instrument’s Application
Development Environments such as LabVIEW, Measurement Studio, or with hardware
product drivers such as NI-488.2 and NI-DAQ.
