Important Safety Instructions
WARNING: High Energy and High Voltage
Exercise caution when using 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.
WARNING
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. If service is necessary, please return the power
supply to the factory Authorized Service Center. See “Return Material
Authorization Policy” on page WA–3.
WARNING: Limitations on use
The XTR 850W GPIB and Ethernet Interface Option is not intended for use in
connection with life support systems or other medical equipment or device.

Chapter 1, “GPIB” provides information and procedures
on programming the XTR 850 Watt Series Programmable
DC Power Supply from the GPIB (General Purpose
Interface Bus) interface.

GPIB
1-2 M370046-06
Overview
The power supply can be programmed from a remote terminal using a
GPIB interface. Communication over the GPIB interface meets IEEE
488.2 standards and are Standard Commands for Programmable
Instrumentation (SCPI) compliant.
Codes and Standards
The GPIB interface of the XTR 850 Watt Series Programmable DC
Power Supply has been implemented according to IEEE Std 488.1-1987,
IEEE Standard Digital Interface for Programmable Instrumentation. The
communication protocol complies with IEEE 488.2-1992.
GPIB Interface Description and Required Cable Size
The GPIB interface is an 8-bit parallel data bus having a host of bus
commands for synchronization and up to one megabyte data transfer rate.
Use standard IEEE-488, 26 AWG GPIB cable up to 3 metres in length.
GPIB Pin Description
The GPIB port is a special GPIB female connector. See Figure 1-1.

Communication with Your Device
This section provides information on selecting the GPIB interface as the
communication port used on the XTR, and it also provides an example of
how commands can be sent and received. The details of the IEEE 488.2
and SCPI status reporting register structures and a complete list of
commands available can be found in the XTR 850 Watt Series
Programmable DC Power Supply Operating Manual.
Selecting a Communication Port
To select the GPIB as the communication port:
1. Turn the 9-Position Mode Control Knob to PGM.
rE is displayed in the output voltage display.
2. Turn the Rotary knob/Enter button to select the 6PIb communication
port.
3. Press the Rotary knob/Enter button.
ADDR is displayed on the output voltage display.
4. Turn the Rotary knob/Enter button to select the desired address
between 1 to 30. For the purpose of this example, 10 will be selected.
5. Press the Rotary knob/Enter button to commit the new address.
6. Click Scan For Instruments on the GPIB Explorer toolbar. See
Figure 1-2.
The power supply will be found as shown in Figure 1-2.
Important: This section uses the National Instruments™ MAX program to
communicate with the XTR. This is for demonstration purposes only. Any
software that is capable of addressing a GPIB device and sending and receive
text could be used in its place. Consult your GPIB card manufacturer to see if
they provide an equivalent program.
