Local Lockout Using NI-488.2 and C++

This example uses the NI- 488.2 library to set the signal generator local lockout mode. Launch
Microsoft Visual C++ 6.0, add the required files, and enter the following code into your .cpp source
file. niex2.cpp performs the following functions:
• all front panel keys, except the contrast key
• places the signal generator into remote
• prompts the user to verify the signal generator is in remote
• places the signal generator into local
The following program example is available on the signal generator Documentation CD- ROM as
niex2.cpp.

Local, control.
! Declares a variable to hold signal generator address
! Resets signal generator parser and clears any output
! Places the signal generator in local mode
! Places the signal generator in remote mode
! Clears the controllers display
! Places the signal generator in a defined state
! Puts the signal generator in LOCAL LOCKOUT mode
! Prints user prompt messages
! Returns signal generator to Local control
