HALF-DUPLEX
FULL-DUPLEX
This method lets the projector make two way communication, but only one
direction, either transmitting or receiving data, is allowed at a time.
The method does not allow the projector to receive the data from the computer
while waiting for response data from an external device. After the projector
receives the response data from an external device or the response limit time is
past, the projector can receive the data from the computer.
That means that the projector controls transmitting and receiving the data to
synchronize the communication.
To use the HALF-DUPLEX method, set up the RESPONSE LIMIT TIME following
the instructions below.
Using the RESPONSE LIMIT TIME menu, set the waiting time for response data
from an external device. (
