3.8.4.1 HALF-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 and BYTES INTERVAL TIMEOUT, following the instruction below.

	TCP/IP data	Protocol change	Serial data
	Ethernet		RS-232C
	LAN cable		RS-232C cable External device
	Computer
	Transmitting data
			Transmitting data
