6.4 Transmission method
6.4.1 HALF-DUPLEX
The transmission method can be selected from the menus, only when the
NETWORK BRIDGE is selected for the COMMUNICATION TYPE.
(&OPTION menu – SERVICE – COMMUNICATION in the User’s Manual)
HALF-DUPLEX  FULL-DUPLEX
This method lets the projector engage in two-way communication, but only one
direction, either transmitting or receiving data, is allowed at a time.
This method does not allow the projector to receive data from the computer when
it is 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 the data transmission and receipt
synchronization.
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. (&OPTION menu – SERVICE – COMMUNICATION
