To prevent damage to your GPIB-USB hardware and other system components, do
any of the following:
•
Ensure that your system and all instruments connected to it share the same ground
potential. This eliminates the possibility of voltage differential running through
your system.
•
Use a GPIB-120B Bus Isolator/Expander to isolate GPIB systems and expand the
GPIB interface up to 28 devices.
•
Use a pair of GPIB-140A High-Speed Fiber-Optic Bus Extenders. This
transforms the GPIB signals at each end into fiber optic signals, allowing each
unit to reside at a different ground potential.
•
Use an isolated USB hub.
Complete the following steps to install your interface:
1.
Connect the USB connector from the GPIB-USB interface to an available USB Type A port
on your computer.
2.
Before connecting the GPIB-USB interface to GPIB devices, ensure that the computer and
the GPIB devices are at the same ground potential. The GPIB-USB interface connects
directly to most GPIB devices without requiring a GPIB cable.
3.
If your computer is already running, the operating system automatically detects the GPIB
interface. Otherwise, the GPIB interface is detected when you start your computer.
