3. Network Functions
• With using the HALF-DUPLEX method, the projector can send out
254 byte data as maximum at once.
• If it is not required to monitor the response data from an external device and
the RESPONSE LIMIT TIME is set to OFF, the projector can receive the data
from the computer and send it out to an external device continuously.
The OFF is selected as the default setting.
• In case that 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
3.8.4.2 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.
With using this method, the computer and an external device will send the data
out of synchronization. If it is requited to synchronize them, set the computer to
make the synchronization.

2) If the response data from an external device is blank in a certain time period
(BYTES INTERVAL TIMEOUT), the projector judges that the response data is
finished, and starts to send data again.
If a blank time in the response data is longer than the BYTES INTERVAL
TIMEOUT, the projector cannot receive all data, then the computer may not
be able to control an external device well.
Using the BYTES INTERVAL TIMEOUT menu, set the waiting time for
response data to match your system. ( OPTION menu - SERVICE -
