GPIB

Communication with Your Device

This section provides information on selecting the GPIB interface as the communication port used on the XG, 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 XG 850 Watt Series Programmable DC Power Supply Operating Manual (M370046-01).

Selecting a Communication Port

To select the GPIB as the communication port:

1.Turn the 9-position Mode control to PGM. rE is displayed in the output voltage display.

2.Turn the rotary Adjust/Enter control to select the 6PIb communication port.

3.Press the rotary Adjust/Enter control.

ADDR is displayed on the output voltage display.

4.Turn the rotary Adjust/Enter control to select the desired address between 1 to 30. For the purpose of this example, 10 will be selected.

5.Press the rotary Adjust/Enter control 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 XG. 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.
