11.2 General Command Structure
Requesting a parameter (Poll Mode)
?ECR
“?“ is the command for “Request“
“E“ is the parameter requested
“CR“ (carriage return, 0Dh) is closing the request.
Remark: It is possible to close with “CR“ “LF“, 0Dh,
0Ah, but not necessary.
Setting a parameter (Poll Mode)
The parameter will be stored into the device EEPROM.
E=0.975CR
“E“ is the parameter to be set
“=“ is the command for “set a parameter“
“0.975“ is the value for the parameter
“CR“ (carriage return, 0Dh) is closing the request
Remark: It is possible to close with “CR“ “LF“, 0Dh,
0Ah, but not necessary.
Setting a parameter without writing into the EEPROM (Poll Mode)
This function is for test purposes only.
E#0.975CR
“E“ is the parameter to be set
“#“ is the command for “set parameter without writing
into the EEPROM“
“0.975“ is the value for the parameter
“CR“ (carriage return, 0Dh) is closing the request.
Remark: It is possible to close with “CR“ “LF“, 0Dh,
0Ah, but not necessary.
Device response format:
!E0.975CRLF “!“ is the parameter for “Answer“
“E“ is the parameter
“0.975“ is the value for the parameter
“CR“ „LF“ (0Dh 0Ah) is closing the answer.
