Each command consists of a command letter, followed by an equals sign and a
parameter value in hexadecimal number representation. The command letter is
case sensitive. Hexadecimal values are always upper case and consist of 1 to 4
digits. The command is activated by a carriage return ([CR], ASCII character
number 0x0D).
Serial communication operates in echo mode by default. This means that each
character received by the module is echoed back to the sender.
In all command examples the characters sent to the camera are represented in
Bold Courier Font and the camera’s answer in Plain Courier
Font.
The serial commands have the following fixed scheme:
> B=wxyz[CR]
Example (activate correction data set number 0):
1. The user sends the four characters
S=0[CR]
2. The camera answers with seven characters
S=0[CR][CR][LF]>
3. A terminal program without local echo displays
S=0
>
After successful execution of the command, the command input character > is
output. If any error occurred somewhere previous to the prompt a question
mark character
? is displayed.
To query a parameter value, send the corresponding command letter followed
by the equals sign and a question mark character:
> s=?[CR]
