Connecting the GPIB
The following figure shows the standard GPIB connector and how it can be connected in parallel, or
“stacked” with other connectors. Attach the GPIB connectors and secure them by tightening the
screws to prevent them from coming apart during use.
The following conditions should be observed when using a GPIB interface:
•
The total GPIB cable length in a single bus system must not be more than 20m (you can calculate the
current cable length using the formula total length = n
×
2m, where, n is the number of devices to be
connected, including the GPIB controller).
•
No more than 15 devices can be connected to a single bus system.
•
There are no restrictions concerning the method of connection between cables. However, no more
than three GPIB connectors should be connected to a single device, since more than this may damage
the connector mounting due to excessive strain.
(Example) The total cable length in a system with five devices should be 10m or less (2m
×
5 devices =
10m). There is no restriction on the length of the cables between the individual devices as long
as the total length does not exceed 10m. However, if you connect 10 devices or more, make
sure that at least some of the cables attaching the devices are less than 2m so that the total is
less than 20m.
