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 receiver (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
One response is always returned for each command sent from the PC.

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.

The PC side cannot send the next user command before a response for the first command is returned.
If 2 or more user commands are received in a single port, user commands from 2nd one are discarded.
