2. Read commands of calibrator's output and information about calibrator
Function
Read calibrator’s info
Command
VR_[CR][LF]
Answer
<INFO_STRING>[CR][LF]
Description
Return calibrator’s info string. It is first command that should be use after opening
communication port to check if communication is established.
Answer
parameter(s)
<INFO_STRING>
string contains 6 parts separated with spaces:
“C300 f.f.f date yyyy-mm-dd S/N: nnn”
f.f.f
– string with firmware version, e.g. 4.0.7 (max. 9 chars)
nnn
– string with serial number (max. 19 chars)
Example answer
C300 4.0.7 date 2006-06-27 S/N: 23007[CR][LF]
Function
Read frequency output module info
Command
S0VR_[CR][LF]
Answer
<INFO_STRING>[CR][LF]
Description
Return frequency output module info string. It is command that should be use to check if
frequency output module is enable and what kind of mode is running.
Answer
parameter(s)
<INFO_STRING>
string contains 2 parts separated with space:
“FFFFvNNN YYYYMMDD”
FFFFvNNN
– mode code (FFFF) and program version number (NNN)
YYYYMMDD
– date of program build
Example answer
FIRMv004 20100622[CR][LF]
(frequency output module is running in firmware mode and ready to setting the frequency)
BOOTv001 20100521[CR][LF]
(frequency output module is running in boot loader mode and ready to updating the firmware)
ER[CR][LF]
(frequency output module is disabled or communication is failed)
Function
