3. Communication Flow
Transmission sent
At the sending side (PC), the transmission is sent within character intervals of Tc (character interval
timeout).
Transmission received
At the receiving side (Projector), data able to be received within the character interval of Tc is held,
and receiving of a delimiter is considered “transmission received”.
If a received character interval exceeds Tc or a delimiter is not received within 256 characters, all data
already received is lost, and the mode is reset to receive standby again.
Command/Response
One response is always returned for each command sent from the PC. (However, note that a response
may not be returned when the internal receive buffer overflows due to reception of a large amount of
data.)

Response
* The timeout interval between command and response (Tr) is 15 seconds.
Response Reception Timeout
If a response is not received within Tr (timeout interval between command and response) while in
response reception standby after sending a command at the PC, resend the command in the “response
reception timeout”.
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 a 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.
Response to the first processed user command will not be returned.
If user commands arrive at the LAN and service port simultaneously, both will be processed. It will be
processed individually, and return a response to each command to individual ports.
