5.3.1 GPIB Connection
When configuring a GPIB system, the following restrictions must be adhered to.
 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) and the
total length of cable must not exceed 20 meters.
 A maximum of 15 devices can be connected on one bus system.
 There are no restrictions on how the cables are connected together. However, it is
recommended that no more than four piggyback connectors be stacked together on any one
device. The resulting structure could exert enough force on the connector mounting to damage
it.
Figure 5-3 shows the GPIB interface on the rear panel of the 5492BGPIB.

To allow many parallel connections to one instrument, stack the connector. Two screws are located on
each connector to ensure that connections remain secure. Figure 5-4 shows a typical GPIB system
interconnection.
