2-6. Communication Rules
. When sending a command from CONTROLLER, the return Data from PROJECTOR should be
received first before sending the next command. Even if the next command is sent before receiving the
return Data, since PROJECTOR will not be able to receive that command, it does not return a response
to CONTROLLER. Consequently, no error code is also sent.
The following lists the approximate waiting times for PROJECTOR to return the return Data after
CONTROLLER sends the command.
. When a communication error occurs, PROJECTOR ignores the Data received until now, and set into
the reception standby state.
. For undefined commands or commends determined as invalid by PROJECTOR, PROJECTOR will
send the “NAK” return Data to CONTROLLER .
. Take note that when Data is written when the input signal of PROJECTOR is unstable, that Data
(value) will not be incorporated.
. When INDEX specified SIRCS direct command is transmitted, leave an interval of 45 msec until the
next transmission. (Do not return the return Data (ACK, NAK) when the SIRCS direct command is
received.)
2-7. Approximate Return Waiting Times
The await-return time differs according to the model.
Refer to Appendix B.
2-8. Standby Mode
Standby mode is a mode that reduces the consumption power during standby. The initial state is set to
“Standard”. When set to “Low”, restrictions may be applied to communications, so choose the appropri-
ate setting for the application. For more information about communication restrictions, refer to the
“Appendix” in this manual.
