Safety
WARNING—High Energy and High Voltage
Exercise caution when using and calibrating a power supply. High energy levels
can be stored at the output voltage terminals on a power supply in normal
operation. In addition, potentially lethal voltages exist in the power circuit and on
the output and sense connectors of a power supply with a rated output greater
than 40 V. Filter capacitors store potentially dangerous energy for some time after
power is removed.
CAUTION
Operate the power supply in an environment free of flammable gases or fumes.
To ensure that the power supply’s safety features are not compromised, use the
power supply as specified in this manual and do not substitute parts or make any
unauthorized modifications. Contact the service technician for service and repair
help. Repairs must be made by experienced service technicians only.
Warnings,
Cautions,
and Notes

Operating Manual for RS-232 for XPD Series Power Supply
Section 1. Features and Specifications
Description
The RS-232 Interface is a microprocessor-controlled option card for all models of
the XPD Series of DC output power supply. Installed internally, the RS-232 interface
card gives you remote digital control of simple test systems. It features fast, 16-bit
resolution for programming and readback and uses bit serial protocol for sending
data between the computer and the interface. The RS-232 interface has an extensive
command set and uses most of the user-programmable features employed by all of
our interfaces.
In addition to the RS-232 port and its interface, this remote control application
requires a computer-based communications software package such as PROCOMM,
XTALK, Windows Terminal Program, equivalent communications software, or low
level or high level language programs. The RS-232 interface is an ideal tool for
reliable, remote power supply control of both research and development
applications.

Section 2. Installation and Configuration
!
Introduction
To use this product, you must have the following equipment:
• a compatible model of DC output power supply
• serial extender cable (straight through)
• computer with an RS-232 interface (serial port)
• computer-based communications software package
The RS-232 interface is usually installed at the factory. Your local distributor or
service center can also install the interface, especially for use in a
previously-purchased supply already on site. You must then configure the RS-232
Interface-enhanced supply for your system using the “Basic Setup Procedure” on
page 19. Refer also to Figure 2.1, on page 16, Figure 2.2, on page 17 and Figure 2.3,
on page 18 for drawings of the front panel, the interface subplate, and the RS-232
interface printed circuit board (PCB).
Initial Inspection
CAUTION
If you remove the unit's cover, use proper static control techniques to avoid damage
to static-sensitive components on the printed circuit board.
On first receiving your unit, perform a quick physical check.
• Ensure each package contains a power supply with its RS-232 interface board
installed, and manuals for the power supply and the RS-232 interface. Any
additional parts shipped with the power supply will be identified in the supply's
documentation.
• Inspect the unit for any signs of physical damage such as scratches, cracks, or
broken switches, connectors, or displays.
• Check the printed circuit board and components if you suspect internal damage.
If the unit is damaged, save all packing materials and notify the carrier immediately.
For additional information, please see the section titled, “Returning Power Supplies
to the Manufacturer” in the manual shipped with your complete unit.
