Supported remote interfaces
The Series 2280 supports the following remote interfaces:
GPIB
: IEEE-488 instrumentation general purpose interface bus
USB
: Type B USB connection
Ethernet
: Local area network ethernet communications
GPIB communications
This topic contains information about GPIB standards, bus connections, and primary address
selection.
The Series 2280 GPIB interface is IEEE Std 488.1 compliant and supports IEEE Std 488.2 common
commands and status model topology.
You can have up to 15 devices connected to a GPIB interface, including the controller. The maximum
cable length is the lesser of either:
The number of devices multiplied by 2 m (6.5 ft)
20 m (65.6 ft)
You may see erratic bus operation if you ignore these limits.
Install the GPIB driver software
Check the documentation for your GPIB controller for information about where to acquire drivers.
Keithley Instruments also recommends that you check the vendor's website for the latest version of
drivers or software.
It is important that you install the drivers before you connect the hardware to prevent associating the
incorrect driver with the hardware.
Connect the GPIB cables to your instrument
To connect a Series 2280 to the GPIB interface, use a cable equipped with standard GPIB
connectors, as shown below.
