Selecting the Remote Interface Port
To enable or select a port for remote control of the Meter:
1. Press .
2. Press .
3. Press .
4. Press the soft key labeled with the desired port: , , or .
Port selection is non-volatile. Therefore, the selected port will remain active until another
port is selected through the front panel.
Configuring the IEEE-488 Port
The IEEE-488 interface is designed in compliance with supplemental standard IEEE-
488.2. Devices connected to the bus in a system are designated as talkers, listeners,
talker/listeners, or controllers. The connector for connecting the Meter to the IEEE-488
bus is located on the rear panel. Under control of an instrument controller, the Meter
operates exclusively as a talker/listener on the IEEE-488 bus.
The Meter conforms to the Standard Specification IEEE-488.1 – 1987: IEEE Standard
Digital Interface for Programmable Instrumentation, and to IEEE-488.2 - 2004: Codes,
Formats, Protocols, and Common Commands.
IEEE-488 Operating Limitations
The following limitations govern the IEEE-488 remote interface:
• A maximum of 15 instruments may be connected in a single IEEE-488 bus system.
• The maximum length of IEEE-488 cable used on a single IEEE-488 system must be the
lesser of 20 meters, or 2 meters times the number of devices in the system.
Setting the IEEE-488 (GPIB) Port Address
Before the Meter will accept commands through the IEEE-488 remote interface, IEEE-
488 must first be enabled or selected as the active interface port. This can only be done
through the Meter’s front panel.
A controller uses an address between 1 and 32 to identify a specific instrument on the
bus. The Meter is shipped from the factory with the IEEE-488 port address set to 1. To
change the IEEE-488 address:
1. Press .
2. Press .
3. Press .
4. Use the soft keys to set the address as follows.
Select the address digit to adjust by pressing either  or .
With the desired digit selected, press the soft key labeled  to decrement the digit
or  to increment the digit.
5. With the desired address set, press .
