How large a system
can you con gure?

A maximum of 15 devices can be connected on one bus system.

The length of cable between one device and another must be
less than or equal to four meters. The total length of cable in
one bus system must be less than or equal to two meters times
the number of devices connected on the bus (the GPIB
controller counts as one device). The total length of cable
must not exceed 20 meters.

Star, linear, and combinational cable con gurations are
allowed. There must be no loop.

It is recommended that no more than four piggyback
connectors be stacked together on one device. Otherwise, the
resulting structure could exert enough force on the connector
mounting to damage it.
