Installation, cont’d

The audio level for each local input can be individually set via the front panel or serial port control to ensure that the level on the output does not vary from input to input. See chapter 3, “Operation”, chapter 4, “Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6, “HTML Operation”, for details.

D	Input Select switches — For inputs 1 through 3 (matrix sizes 1616
	and smaller) or inputs 1 through 6 (matrix sizes 1632 and larger),
	set these DIP switches to the Local (up) position to select the local
	(RGB video and audio) input. Set the DIP switches to the RJ-45
	(down) position to select the MTP input.

E	RS-232 Output Insert connectors — For bidirectional RS-232 data that is
	routed to a specific (unswitchable) TP output, connect a serial device to one of
	these 3.5 mm, 3-pole captive screw connectors. Figure 2-7 shows how to wire
	the connectors.

N• For the RS-232 Output Insert to be available on the TP output, the insert must be enabled via an SIS command, the Windows-based control program, or an MTPX Plus HTML page. See chapter 4, “Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6, “HTML Operation” for details.

•When an RS-232 output insert is enabled, any content on the audio/RS-232wire pair for the TP input tied to that output is disabled.

•Each RS-232 output insertion is dedicated to the output with that number; for example, RS-232 Output Insert 1 is always routed to the Output 1 TP connector (when enabled as described in the note above), RS-232 Output Insert 2 is routed to the Output 2 TP connector, and so on.

•The switch time for the RS-232 output insert is 50 ms.

Signal outputs

F	Outputs (MTP) connectors — Connect the TP inputs of compatible MTP or
	VTT receivers to these RJ-45 female connectors.

CDo not connect this device to a computer data or telecommunications network

NSee the Inputs connector, item A, in the “Signal inputs” section, for detailed pin assignments for the RJ-45 connectors.

NFor best results, use a cable length of at least 50' (15 m) between the TP output connector and the receiver.

G	Local Outputs (VGA) connector(s) — Connect one or two RGBHV video
	displays to these 15-pin HD female connectors for each output.
