1. General information
In order to communicate with C300 calibrator, please use standard RS232 cable and RS232
communication port. If you don’t have RS232 port in your computer, you can use USB port and
USB/RS232 converter dongle.
Communication port settings are:
Speed 57600 bauds,
8 bits DATA,
1 bit STOP,
No parity,
RTS/CTS handshake flow control.
Communication with the calibrator is done with Master/Slave scheme. PC (Master) can communicate
with calibrator (Slave) via set of ASCII commands. All commands should be written with CAPITAL
characters. Each command ends with line termination sequence of two ASCII characters with decimal
codes 13[CR] and 10[LF].
For each command from PC there is an answer from the calibrator:
The structure of command is following:
COMMAND_<PARAM1>,<PARAM2>,<PARAMx>[CR][LF]
The structure of answer is following:
OK[CR][LF]
(everything is OK, calibrator have realized command)
or
ER[CR][LF]
(problem with the transmission or bad command syntax)
or
<ANSWER_PARAM1> <ANSWER_PARAMx>[CR][LF]
(everything is OK, calibrator answered with parameters).
