6.4.1 HALF-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.
