Instrument access
You can specify that the control interfaces request access before taking control of the instrument.
There are several modes of access.
You can set one of the following levels of access to the instrument:
None: Allows access by one remote interface at a time with logins required from other interfaces
All: Allows access by one remote interface at a time with passwords required on all interfaces
The front-panel is read-only when you are using a remote interface. You can view the home, graph,
or data sheet screen by sending :DISPlay:SCREen command.
When you set access to None, you need to send a :SYSTem:COMMunication:ABORt command
using this interface to use another interface. You do not need a password with this access.
All access is similar to None access, except that you must send a :SYSTem:PASSword:UNLock
command with the password before sending the SYSTem:COMMunication:ABORt command.
Changing the instrument access mode
To change the access mode Using SCPI commands:
:SYST:PASS:MODE NONE
:SYST:PASS:MODE ALL
