8. Set the required parameters and connect the instrument
Communication ID in parameter to the Communication ID out
parameter from EXIQSBASE_OpenComm.vi.
The example below shows how to configure the

source. In this example, Set was chosen and the PowerState parameter
was set to True.
9. Repeat steps 7 and 8 for each of the functions you want to use.
However, you have to link Communication ID in of the new driver to
Communication ID out of the preceding driver.
Note: If you want to use platform or IEEE 488.2 commands, add the desired driver
to your VI and configure its parameters exactly as you would do with any
instrument function.
