Path Control Menu
Description
The Path Control Menu automatically retrieves pathnames stored
in non-volatile memory at startup and provides the user with direct
control of pathnames from the 1256 front-panel display. It allows
the following operations:
•
View the states of pathnames (closed or open) in the
system.
•
Set pathname filter masks to wildcards or to specific
characters to limit the display of pathnames to those
meeting particular user-criteria.
Defining a Path
The 1256 front-panel enables the user to manually close or open
pathnames after they have been defined remotely using the SCPI
path definition command through one of the remote interfaces.
Refer to “
Naming a Path
” section in Chapter 5 for more details on
defining path names.
Once a path is defined through a remote interface, it is immediately
available for display and use on the front-panel and will remain
visible until either 1) the power is removed from the system or 2)
the path is removed remotely using the SCPI path delete
command. If the intent is to define the pathnames and make them
accessible to the front panel after power is cycled to the 1256, the
defined pathnames must also be stored in non-volatile memory.
Refer to “
Storing Path Names in Non-Volatile Memory
” section
in Chapter 5 for more details.
It is important to realize that the SCPI command language allows
pathname lengths that exceed the display capability of the 1256
(18 characters). If pathnames are defined greater than 18
characters, only the first 18 characters will be visible. It is also
only possible to selectively filter the first 18 characters using the
