Appendix D: Model 2450 in a Model 2400 application
Model 2400 to 2450 differences
You can use a Model 2450 in an existing Model 2400 application. The instruments are mostly
compatible, with the following exceptions:
•
There is no RS-232 communication port.
•
The contact check function is not available.
•
Some commands operate differently or are no longer available. These differences are described
in the following sections.
Model 2400 commands that are supported but operate differently
The command :DISPlay:CNDisplay is supported in the 2400 SCPI command set, but will return
the display to the home screen.
The commands :OUTPut:ENABle[:STATe] and :OUTPut:ENABle:TRIPped? are supported in
the 2400 SCPI command set, but they affect the Model 2450 rear panel INTERLOCK connection
instead of the DIGITAL I/O connection.
