Command types
There are two types of commands: setting commands and request commands.
Setting command
This type of command serves for changing the VM-55 status or mea-
surement parameters. Only some commands of this type will produce a
response from the VM-55. The response consists of status information
returned after the setting command has been processed.
Request command
This type of command serves for getting information about unit settings
and for obtaining measurement data including display data and stored
data. The VM-55 returns the requested data.
Command format
Setting command
Command = “$” + “command name” + “,” + “parameter” + [CR] + [LF]
The basic components of a setting command are the command name and
the parameter. “$” at the beginning represents the processing state of the
command and is automatically displayed. During the processing of the
command, “$” is not displayed and does not accept the command input. A
comma is used as delimiter between the command name and parameter,
and the setting command is terminated by a [CR]+[LF] (carriage return
+ line feed). The setting command uses the CSV format.
Prohibited items of setting command
• Spaces in a command name may not be omitted.
• Spaces in a command name may not be doubled.
• The “,” (comma) after the command name may not be omitted.
• Japanese full-width characters are not allowed.
