Texas Instruments MATRIX 3000 System Integration Gpio Connector, Communicating to, All Ports

Section 2: Installation and Setup

	NOTES: Only the port and IP address of the projector can be changed. The subnet
	mask is fixed (255.255.255.0).
	CHANGING THE PORT#: On some Ethernet networks, firewall restrictions may require
	that the port number of the projector be changed from its default of 3002. If so, enter a
	new port number in the Ethernet Settings menu or include the new port# in an XIP
	serial command sent to the projector.
Separating Networks	f By default, communications originating from one type of serial controller—RS232 vs.
	RS422 vs. Ethernet—stay on the corresponding network path. This separation is
	indicated by a “Separate” setting for “Network Routing” in the Communications
	menu. If you are using an RS422 controller, for example, it will communicate only
	with the projector to which it is connected unless you change this setting to either
	“RS232 and RS422 Joined” or “All Joined”.
Communicating to	f To relay all messages to all ports—RS232, RS422, and Ethernet—set the “Network
All Ports	Routing” option in the Communications menu for each projector to “All Joined”. This
	configuration is useful if you are using a non-RS232 controller with the RS232 linking
	available between these projectors. For example, you may want to use both an RS422-
	compatible controller and an Ethernet-connected PC for working with a network of
	projectors linked via their RS232 in/out ports (Figure 2.20).

GPIO Connector

Figure 2.21. All Networks

To isolate just RS422 communications, select “RS232 and Ethernet Joined”. In Figure

2.21only projector #3 will respond to the RS422 controller. To isolate just Ethernet communications, select “RS232 and RS422 Joined”—only projector #1 will respond via Ethernet.

The GPIO (General Purpose Input Output) connector on the input panel can be used to provide a method of interfacing a wide range of external I/O devices to the projector.

Refer to Appendix E: System Integration for complete details on pin configuration and how to program the various pins on the connector.
