 • 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 devise 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 devise 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 devise well 
depending on the processing status of the projector .
 NOTE 
 NOTE 
3.7.4.2 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 devise.
With using this method, the computer and an external devise will send the data 
out of synchronization. If it is requited to synchronize them, set the computer to 
make the synchronization.
