Diagnostics 9.1
Error diagnosis by serial communication protocol 9.1.1.
Within the communication protocol, the command and data are combined in a message.
After receiving a message the camera responds with an acknowledgement character. This can be an
ACK character (positive acknowledgement) or a NAK character (negative acknowledgement).
The ACK response is given when the received message was understood (the content of the message
is not considered).
The NAK response is given when the received message was not understood, which may be the case
when invalid characters are received as message content, or the message overruns the camera
receiver buffer capacity.
However, the communication protocol itself does not check the content and validity of a message.
After each attempt to execute a command, the error register is set. To verify whether a command is
succesfully executed or not, the result should be read back from the camera.
Command syntax: ERR?
The ERR command returns a single integer value.
A list of possible error codes and the cause are shown below:
