GPIB Interface (Special Order)
GPIB connection is via a 24pin IEEE-488 Centronics connector on the rear panel of the unit.
This interface option allows the unit to be connected to a GPIB controller and other GPIB
devices. A GPIB system can be connected in any configuration (star, linear, or both) as long
as the following conditions are met:
•
The maximum number of devices including the controller is equal or less than 15.
•
The maximum length of the GPIB cable is no more than 2 meters.
•
The total lead length of all devices connected together totals less than 20 meters.
•
Please make sure the lock screws are firmly hand-tightened, use a screwdriver only
for the removal of screws.
Each device on the GPIB (IEEE-488) interface must have a unique address. You can set the
address of the CFS series to any value between 0 and 30. The address can only be set from
the front panel. The address is stored in non- volatile memory and does not change when
the power has been off or after a remote reset.
Note:
The address is set to 8 when the power source is shipped from the factory.
The GPIB connector pin-out is defined by the IEEE-488 standard and shown for reference
only in Table 6-14 below.
