Remote communications interfaces

You can choose from one of several communication interfaces to send commands to and receive
responses from the 2281S.
The 2281S can be controlled from only one communication interface at a time. The first interface from
which it receives a message takes control of the instrument. To remove control from the present
interface, send the following command:
:SYSTem:COMMunication:ABORt
The 2281S powers up using the last remote interface used.
