message terminators:

These terminators are compatible with most controller application

Entering Commands
The standards that govern the command set for the programmable
power supplies allow for a certain amount of flexibility when you
enter commands. For example, you can abbreviate many commands
or combine commands into one message that you send to the
programmable power supply. This flexibility, called friendly
listening, saves programming time and makes the command set
easier to remember and use.
Command Characters
The programmable power supplies are not sensitive to the case of
command characters. You can enter commands in either uppercase or
lowercase.
You can precede any command with white space characters. White
space characters include a space or any combination of the ASCII
control characters hexadecimal 00 through 1F except for the
character 0A (line feed). You must, however, use at least one space
between the parameter and the command header.
