Every command that is sent to the LDP-QCW must be completed with a CR (Enter). It consists of a
command word followed by one ore more a parameters. If the command was successfully executed a
“00” is sent, otherwise a “01”. If there is an error pending, the response will be “10”, otherwise
“11”. If the command requires an answer parameter, this parameter is sent before the confirmation is
given.
Example:
The user would like to read out the actual setpoint current:
User input:
gcurrent<Enter>
Output of the LDP-CW: 250<CR><LF>
00<CR><LF>
Example 2:
The user would like to set a new setpoint current:
User input:
scurrent 270<Enter>
Output of the LDP-CW: 270<CR><LF>
00<CR><LF>
Input is done in ASCII code and is case sensitive. Every terminal can be used that supports this
standard.
