Command Format
To input (send) a command, delimit a command name
and parameters with spaces, and press the Carriage
Return (CR) key.
The following shows the input format and an example:
<Input format> command param1 param2 [CR]
<Input example> PARTIAL 1 <CR>
Input characters are case-insensitive.
Use hexadecimal numbers for parameters.
Command Input and Response
When the camera receives commands from the host, it
returns a response after each command is processed.
Input commands are echoed back.
Note
To input multiple commands in sequence, input a
command after the previous command returns its
response.
Command response messages are as follows:
OK : normal
Error : syntax error
Error : status error
■
When command execution is completed normally,
“OK[CR]” is returned.
Example:
<Input> PARTIAL 1 <CR>
<Output on screen> OK[CR]
■
If command execution is terminated abnormally,
“Error[CR]” is returned.
■
When no parameter is input for a command
requiring parameters, the current parameters of the
command are returned.
Example:
<Input> PARTIAL<CR>
<Output on screen> 1[CR]
■
If an input value is out of parameter range or an
invalid command name is input, the command is
invalid and “Error[CR]” is returned.
<Input> PARTIAL 5<CR>
<Output on screen> Error [CR]
