(1) Responses to operating commands and setting commands
When execution of a command proceeds normally, a reply with the executed command
(with parameter) is sent back to the host computer.
XXX_PP
If the command sent by the computer contains an error (undefined command,
parameter error), the character string below is sent as an error message.
(2) Responses to status commands
This is always output; regardless of the RES command setting.
When the camera interprets a command as being proper, the response to the
command's execution is to send back to the host computer the required status.
Accordingly, the status command is executed normally, and the response is the
transmission of the status to the host computer.
XXX_PP
Just as described above, when the command sent by the computer contains an error
(undefined command, parameter error), the character string below is sent as an error
message.
(3) Reply when error occurs on reception
There are two things to be considered when an error occurs during reception. One is
framing, parity, or overrun errors; the other is the possible overloading of the input
buffer. The fact that one of these errors has occurred is transmitted in the character
string below.
Here, n indicates an error, with the type of error indicated by the following.
n = 1:
n = 2:
Moreover, when either of the two errors above occurs, the command generating the
error is cancelled from the camera's input buffer.
