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).

Function
Harmonics –switching ON/OFF
Command
HR_<U1>,<U2>,<U3>,<I1>,<I2>,<I3>[CR][LF]
Description
Switching between pure sinusoidal signal (harmonics OFF) and signal with programmed
harmonics (harmonics ON); the switching will be made immediately.
Parameter(s)
<Ux> = 0 harmonics in channel Ux are OFF;
<Ux> = 1 harmonics in channel Ux are ON;
<Ix> = 0 harmonics in channel Ix are OFF;
<Ix> = 1 harmonics in channel Ix are ON;
Example(s)
HR_1,1,1,1,1,1[CR][LF]
(harmonics in all channels are ON)
HR_1,1,1,0,0,0[CR][LF]
(harmonics in U1,2,3 channels are ON, harmonics in I1,2,3 channels are OFF)
HR_0,0,0,1,1,1[CR][LF]
(harmonics in U1,2,3 channels are OFF, harmonics in I1,2,3 channels are ON)
Example answer
OK[CR][LF]
4.2.Setting interharmonics
Function
Setting interharmonic’s amplitude in voltage channels
Command
INTERHARMA_<A1><A2><A3>[CR][LF]
Description
Setting amplitudes of interharmonics in voltage channels. Expressed as percent of first
harmonic.
!!! Command used in firmware 4.0.0 or newer !!!
Parameter(s)
<A1><A2><A3> Values of amplitude of interharmonics (real numbers). Setting range is
presented in Table 2.1 in C300 user manual
Example(s)
INTERHARMA_30.0,10.0,20.0[CR][LF]
(30% of U1 amplitude, 10% of U2, 20% of U3)
Example answer
OK[CR][LF]
Function
Setting interharmonic’s phase angle in voltage channels
Command
INTERHARMP_<P1><P2><P3>[CR][LF]
Description
Setting phase angle of interharmonics in voltage channels. Expressed in degrees.
!!! Command used in firmware 4.0.0 or newer !!!
Parameter(s)
<P1><P2><P3> Values of phase angles of interharmonics (real numbers). Setting range is
presented in Table 2.1 in C300 user manual
Example(s)
INTERHARMP_60.0,15.0,45.0[CR][LF]
(60°, 15°, 45°)
Example answer
OK[CR][LF]
Function
Setting interharmonic’s frequencies in voltage channels
Command
INTERHARMF_<A1><A2><A3>[CR][LF]
Description
Setting frequencies of interharmonics in voltage channels. Expressed in Hz.
!!! Command used in firmware 4.0.0 or newer !!!
Parameter(s)
<F1><F2><F3> Values of frequencies of interharmonics (natural number). Setting range is
presented in Table 2.1 in C300 user manual
Example(s)
INTERHARMA_113,78,300[CR][LF]
(133Hz, 78Hz, 300Hz)
Example answer
OK[CR][LF]
