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.

Operating Manual for Multichannel Functionality (GPIB-M)
Section 1. Features and Specifications
Description
The internal GPIB-M interface card allows you to operate your power supply from
a computer controller via the IEEE-488 communications bus.
The GPIB-M interface allows complete remote programming of your power supply,
including status reporting, settings query, and service request generation with
user-designated conditions. Both the voltage and current output are precisely
programmed directly in volts and amps with 16-bit resolution. Additionally, the
16-bit readbacks measure the actual power supply output. The programming
command set is easy to use and includes software calibration commands. The
interface card comes with several protection features such as programmable over
and under voltage protection, and soft limits.
Multichannel addressing via CANbus allows up to 50 power supplies to be
controlled from one GPIB address. This manual covers operation of both the
GPIB-M and CAN-only interface cards.
Features and Functions
Features • 16-bit programming and readback of voltage and current
• Programmable soft limits for voltage and current
• LED status signals: remote operation, service request and shutdown; (XFR and
XHR only) error, addressed, over voltage protection, auxiliary status bits
• Software calibration
• Automatic voltage/current mode crossover
• Shutdown or warning for over- and under-programmed trip points
• Programmable auxiliary status lines for monitoring power supply conditions
• Remote interlock and trigger lines
• Selectable standby, programmed sequence and other power-on defaults
• Active current sharing with parallel connected units for higher power
requirements
• CANbus communications link for multichannel addressing, and master/slave
current sharing
• Extensive SCPI command set for control and status monitoring

Introduction
To use this product, you must have the following equipment:
• a compatible model of DC output power supply
• IEEE-488 connector and cable
• computer with an IEEE-488 interface card
• Computer-based communications software package
• parallel CANbus cables (to connect power supply for multichannel operation)
The GPIB
Your local distributor or service center can also install the interface, especially for
use in a previously-purchased supply already on site. The interface card will be
calibrated and configured with default settings. You will need to configure the supply
for your system using the “Basic Setup Procedure” on page 31. Refer also to
Figure 2.1, pg. 26, Figure 2.2, pg. 27 and Figure 2.3, pg. 27 for drawings of the front
panels. The interface subplate is different for each product. Please check Figure 2.4
to Figure 2.7.
Initial Inspection
On first receiving your unit, perform a quick inspection.
• Ensure each package contains a power supply with its GPIB interface board
• Inspect the unit for any signs of physical damage such as scratches, cracks, or
• Check the printed circuit board and components if you suspect internal damage.

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.

CANbus cable and a terminator are also supplied with each GPIB-M or
CAN-only interface. Any additional parts shipped with the power supply will be
identified in the supply's documentation.

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.
