ACK message : Returned by the FCB camera when it receives the command. No ACK message is returned for
inquiries.

of inquiry commands, it will contain reply data for the inquiry after the 3rd byte of the packet. If the
ACK message is omitted, the socket number will contain a 0.

Socket number
When command messages are sent to the FCB camera, it is normal to send the next command message after waiting for the
completion message or error message to return. However to deal with advanced uses, the FCB camera has two buffers
(memories) for commands, so that up to two commands including the commands being executed can be received. When the
FCB camera receives commands, it notifies which command buffer was used using the socket number of the ACK message.
As the completion message or error message also has a socket number, it indicates which command has ended. Even when two
command buffers are used, the command for FCB camera management and some inquiry messages can be executed.
The ACK message is not returned for these commands and inquiries, and only the completion message of socket number 0 is
returned.
