Versa Star Pro Meter Remote Control Protocols
Rules for Remote Control Usage
1.
CR (Carriage Return, ASCII 13) is used to terminate a command. Whenever this character
is received, the internal buffer will be processed.
2.
All characters except for NL (New Line, ASCII 10) are significant. The NL character will be
ignored. The meter is not case sensitive, though all lower case characters are converted to
upper case internally.
3.
Only one command can be executed at a time. No new command can be issued until the
current command is finished being processed. When the current command is finished, it
will issue the “>” prompt to the user, indicating a new command can be entered.
4.
Empty commands (i.e. just a CR) will be ignored and a new prompt will be issued.
5.
Incorrect commands will fail to execute. If any commands are mistyped, execute the CR
(Carriage Return) command and then reenter the command.
6.
It is suggested to use the option to “Append line feeds to incoming line ends” within the
ASCII setup within HyperTerminal so the data string ends with a new line instead of
overwriting the last line of data with new data string.
7.
Set the meter communication settings using the
Instrument Settings
setup menu.

Remote Control Engine
The remote control engine receives input from the serial/USB port and processes it as needed.
Commands sent to the remote control interface will be in the form of “OPCODE
<OPERAND(s)>
CR
”. Line feeds will be ignored. New commands cannot be issued until the
previous command has been completed and a prompt is given. A prompt is shown as the
greater than symbol (“>“‘) followed by a space.
Remote Control Commands
1.
The first time the meter is interfaced with a computer, start the terminal program and type
the following commands:
a.
Execute the “SYSTEM” command and confirm a response from the meter.
b.
Execute the “GETUSERINFO” command immediately after receiving a
response from the meter after executing the “SYSTEM” command.
2.
A connection has now been established and the remote commands from the following table
can now be executed. The “>” symbol will be shown when the previous command has been
completed and then a new command can be entered and executed.
