Star A200-A300 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 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.
Turn on the Export Data and Data Log meter settings. The default meter communication
settings are:
Bits per second: 9600
Data bits:
8
Parity:
None
Stop bits:
1
Flow control:
None
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.
