Primary address

The Model 622x ships from the factory with a GPIB address of 12. When the
instrument powers up, it momentarily displays the primary address. You can set
the address to a value of 0-30. Do not assign the same address to another device
or to a controller that is on the same GPIB bus.
Usually controller addresses are 0 or 21 but see the controller's instruction manual
for details. Make sure the address of the controller is the same as that specified in
the controller's programming language. To make sure the unit's interface is prop-
erly selected and configured or to check or change the setting, see
selection and configuration," on page

Tighten the screws securely, making sure not to over-tighten them.
Connect any additional connectors from other instruments as required for
your application.
Make sure the other end of the cable is properly connected to the controller.
Most controllers are equipped with an IEEE-488 style connector, but a few
may require a different type of connecting cable. See your controller's instruc-
tion manual for information about properly connecting to the IEEE-488 bus.
NOTE You can only have 15 devices connected to an
IEEE-488 bus, including the controller. The maxi-
mum cable length is either 20 meters or two
meters times the number of devices, whichever is
less. Not observing these limits may cause errat-
ic bus operation.
