Configuration Requirements
To achieve the high data transfer rate that the GPIB was designed for, the physical
distance between devices and the number of devices on the bus are limited.
The following restrictions are typical.
•
A maximum separation of 4 m between any two devices and an average separation
of 2 m over the entire bus.
