• Select channel 10. “110” is the switch address and is defined as the concatenation of the SCU address and the channel number.
85330A Multiple Channel Controller
Address any SCU, or SCUs, at SCU address 1.
•
Activate switch port 2.

Example 2, for a typical custom system
OUTPUT 70918; “ROUT:CLOS 2,(@110);”
Switch port 2, SCU address 1, channel 10
The command ROUT:CLOS 2,(@110); is sent to GPIB address 70918 (the
85330A). This command string would:
Select channel 2.
•
• Address the SCU (which is set at the factory to SCU address 0). Since the default address is being used, the SCU address is not required, and is not specified in the command.
Activate switch port 1.

Programming
To Use Direct Control
To Use Direct Control
Direct control is where the host computer issues GPIB commands and the 85330A executes them immediately. For example, the ROUTe:CLOSe
(port number) (switch address) command causes the 85330A to immediately change switch states.
Here are examples of how to select a channel.
Example 1, for a standard system
OUTPUT 70918; “ROUT:CLOS 1,(@2);”
Switch port 1, default SCU address (0), channel 2 selected.
In this example, the BASIC OUTPUT command is used to output a command to the 85330A. The command, ROUT:CLOS 1,(@2); is sent to GPIB address
70918 (the 85330A). This command string would:
