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.
