• When using the HALF-DUPLEX method, the projector can send out a
maximum of 254 bytes of data at once.
• If the response data from an external device does not need to be monitored
and the RESPONSE LIMIT TIME is set to OFF (default), the projector can
receive the data from the computer and send it out to an external device
continuously.
• In case the computer controls to synchronize transmitting and
receiving the data, it may not be able to control an external device well
depending on the processing status of the projector.
NOTE
NOTE
6.4.2 FULL-DUPLEX
This method lets the projector make two way communication, transmitting and
receiving data at the same time, without monitoring response data from an
external device.
When using this method, the computer and external device will send the data out
of synchronization. If it is required to synchronize them, set the computer to make
the synchronization.
