Remote control
The standard version of the 1427 is equipped with a RS232 interface.
The IEEE488 version is described in chapter 7.2: “Remote control IEEE488 (optionally)”.
A large part of the commands are the same for both versions.

No parity.
You’ll find further information about the transmission rate at chapter 5.2.6.

used.
The RS232 line is metallically separated to other electronic circuits.
