GPIB cables are available in two lengths:
•
GPIB Cable, 1 meter (3.28 ft.)
•
GPIB Cable, 2 meters (6.56 ft.)
To use the IEEE-488 (GPIB) interface with the 1256 Switching
System, you also need a computer equipped with a GPIB
controller.
Adhere to the following guidelines to maximize the data transfer
rate of the GPIB system:
•
Total cable length of no more than 20 meters (65.6 feet).
•
Maximum separation of 4m (13.2 feet) between devices.
Average separation of no more than 2 meters (6.6 feet).
•
Maximum of 15 devices (including controller) connected
to the bus.
Use a GPIB cable to connect the rear-panel GPIB connector on
the 1256 to the GPIB port of the host computer. Refer to Figure 4-
1, Using the GPIB Interface.
Avoid stacking more than three cables on any single
connector. If the stack is too large, side forces may damage
the connector mounting.
Tighten the locking screws finger-tight on each connector. Do
not over-tighten.
