3. Communication Flow

Transmission sent

At the PC, the transmission is sent within character intervals of Tc (character interval timeout).

Transmission received

At the Projector, the data that is able to be received within the character interval of Tc is held, and the
transmission is considered received when the 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.
WithinTr
* 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.

Control Mode

"LOCAL mode" and "REMOTE mode" on previous models (SX50、SX6、SX60、X600、SX7、X700) have
been removed. You do not need to be aware of which mode it is in (no need to use "REMOTE" and
"LOCAL" commands) to send user commands.

Other

If AC power is supplied to the projector, communication is possible regardless of whether the power is
on or off.
The PC side cannot send the next user command before a response for the first command is returned.
If more than 2 user commands arrive at one port, "BAD_SEQUENCE" will be returned in response to
the second user command.
For procedures which return "BAD SEQUENCE", change the procedure, and do not send the next user
command on the PC side before a response for the first command is returned.
