APPENDIX B ETHERNET COMMUNICATIONS
XR Series power supplies are available with an optional Ethernet interface. When specified
at time of order, an Ethernet interface module is installed to make a second UART port
available for communications. With two UART ports available, RS232 and Ethernet, 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.
Ethernet communications can be made though the Remote Interface Software, a terminal
emulation programs like Microsoft Windows (tm) HyperTerminal Program, or through a
computer’s web page browser. In the latter case, software, programmed into the Ethernet
interface module, allows the power supply to be recognized and to communicate directly
with the computer without the need for additional programs stored in the computer.
An IVI-COM Driver is included with the installation CD and is available for download from
the 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).
B.1 Ethernet Communications using the Remote Interface Software
Chapter 5.0 describes application of the Remote Interface Software which is shipped with
XR 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; Ethernet is included as one of these
interfaces.
To use the Remote Interface Software with optional Ethernet communications, the address
parameters in the Remote Interface Software and that encoded in the power supply must
match. The factory default for DHCP is 1 (on) allowing the IP address to be automatically
set by the DHCP server on the network. If DHCP is set to 0 (off), the power supply’s
address can be manually set. See Section 4.3.12 for setting address parameters. If DHCP is
off and the address is unknown, the device can be located by following one of the
procedures described in Section B.3.2.3.
B.2 Ethernet Communications using HyperTerminal
The following procedure outlines using Microsoft Windows (tm) HyperTerminal Program
to communicate using the Ethernet communications.
