9. System Commands
There are two classes of system commands: one class for configuring the state of the system, and
the other for controlling its operation. The commands are presented in functional, alphabetical
order. Where applicable, examples of the command in use will be given. All commands are input
on the RS-232 serial port and consist of ASCII characters. Additionally, format notations and
conventions for commands and outputs are presented first.
9.1 Command Format Notation and Convention
Use the following format notation to enter commands:
[ ]
Items shown inside square brackets are optional. To include optional items, type only the
information inside the brackets.
Do not type the brackets.
<>
Represents an ASCII carriage return or “enter”. Whenever shown this value must be
present to terminate the command sequence.
...
An ellipsis indicates that you can repeat an item.
,
A comma represents a delimiter in a list of optional parameters. The comma must be
present for those parameters which are omitted except for the case of trailing commas.
For example:
Qs,p1,,,p4<>
is the proper command format when omitting parameters p2 and p3. Commas following
the parameter p4 are not required if parameters p5 and p6 are omitted.
|
A vertical bar means either/or. Choose one of the separated items and type it as part of
the command. For example,
ON|OFF
indicates that you should enter either ON or OFF, but not both.
Do not enter the vertical
bar.
^
Represents the “Ctrl” key.
