Setting the Address

NOTE	The primary and secondary addresses cannot be selected over the GP-IB. However, there are important
	differences in addressing power supplies over the bus depending on if only primary or a combination of
	primary and secondary addresses are used. (See ’’Addressing Over the Bus’’).

Primary Address--is set using the switches A1 through A5 on the rear panel of the GP-IB Board as explained in Section III of this manual. All power supplies connected directly to the GP-IB interface must be set to a unique primary address. This applies whether they are "stand-alone" power supplies or "direct" supplies in a linked configuration.

Secondary Address--is only used when programming in SCPI using linked connections, and is set with the output adjust rotary pulse generator (RPG) in conjunction with the front panel LCL Key. To set the secondary address proceed as follows:

∙Press and hold the LCL button until the secondary address is displayed. The primary address is displayed first, and after two seconds the secondary address is displayed until the key is released.

∙Turn the RPG while the secondary address is being displayed to change the secondary address.

The secondary address can be set from 0 to 15 or null. A null is shown as a ’’- - -" on the front panel LED. Secondary addresses are used as follows:

- - -	Select null "- - -’’ if you are using stand-alone connections only.
0	Select zero as the secondary address for the direct supply only.
1 thru 15	Select 1-15 as secondary addresses for linked supplies only. For linked supplies, the
	primary address is displayed as a null "- - -" when the LCL key is pressed. Note that
	the primary address switch settings are ignored on linked supplies.

Addressing Over the Bus

The following examples show how to address the power supply over the bus using stand-alone and linked connections. The examples assume that the GP-IB select code is 7 and the power supply primary address is 5. They also show the front panel display of the GP-IB Address.
