Communication Flow; Command Transmission (Pc Side); Command Reception (Projector Side); Command/Response - Canon WUX6000 User Commands

3. Communication Flow

Command Transmission (PC side)

Commands should be sent from PC in a way that each character is sent within the specified Tc
(inter-character timeout).

Command Reception (projector side)

The projector retains incoming characters within a specific Tc, and recognizes the data as "received
command" when delimiter is received.
If the character interval received exceeds the Tc or if a delimiter is not received within 256 characters,
all data already received is lost, and the mode is reset to standby to receive commands again.

Command/Response

A response is always returned within Tr(*) for a command sent from the PC.

Within Tr Tr以内
(*) The timeout interval between command and response (Tr) is 15 seconds.

Response Reception Timeout

If a response is not received within the Tr (timeout interval between command and response) while
standing by a waiting response after sending a command from the PC, it is deemed to have exceeded
the "response reception timeout." Please resend the command.

Other

To execute commands via the network, the network function must be enabled in advance.
Only a portion of the commands can be executed when the projector is in standby mode.
The PC side cannot send the next user command before a response for the first command is returned.
If two or more user commands are received, user commands from 2nd one are discarded. If 2 or more
user commands are received, only the 1st command is processed, and a response is returned when
finished.
