Precautions to Be Taken When
Connecting the Cable
• Firmly tighten the screws on the GP-IB cable
connector.
• Multiple devices can be connected to a single GP-IB
system. However, no more than 15 devices
(including the controller) can be connected to a
single system.
• When connecting multiple devices, each device
must have its own unique address.
• Use a cable of length 2 m or less for connecting the
devices.
• Make sure the total cable length does not exceed 20
m.
• When communicating, have at least two-thirds of
the devices turned ON.
• When connecting multiple devices, connect them in
a star or linear configuration (see the diagram
below). Loop and parallel configurations are not
allowed.
