Primary address

The primary address of the S46/S46T must agree with the primary address you intend to
specify in the controller's programming language. There are five GPIB address DIP
switches located on the rear panel adjacent to the IEEE-488 connector. When shipped
from the factory, the GPIB address is set to 7. As shown in
a binary weighted configuration.

Syntax rules for programming the S46/S46T are covered in this paragraph.
Commands and parameters
The general form for SCPI commands is demonstrated in
They are hierarchical in nature and begin with a root command. For example, to open all
channels for relays 1 and 2, send the following command:
:OPEN:ALL
The root path command for the above example is ROUTe. This is an optional command
word (as indicated by the brackets ([ ]) in the table) and need not be used.
Momentarily remove power from the unit after changing the address to update
the address to the new setting.
