RS-232 output inserts

eRS-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 the RS-232 Output Insert 3-pole captive screw connectors.

NEach RS-232 Output Insert must be enabled. See the "RS-232 output inserts enables" SIS commands on page 4-5.

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

Outputs

fTP outputs — Connect up to 8, 16, or 32 (depending on the matrix size) compatible MTP receivers to the Outputs RJ-45 connectors.

g	Local RGB (VGA) outputs — Connect one or two
	RGBHV video displays to the female Local
	Outputs (VGA) 15-pin HD connectors.
	N Matrix sizes 1616 and smaller (excluding the
	MTPX Plus 128) have one local video output.
	Matrix sizes 1632 and larger and the MTPX Plus 128
	have two local video outputs.
	N The Local outputs are always outputs 1 and 2.
	N The video that is output on these connectors is converted
	from the tied proprietary TP input signal or the local
	(VGA) input.
	N This connector can also output HD component video,
	component video, S-video, or composite video if that is the
	video format that was input.
	If the video output is NTSC component video, S-video, or
	composite video, set the output to no sync processing. See
	the "Local video output sync polarity" SIS commands on
	page 4-9.

Figure 2-6 — Audio output connector wiring

NThe MTPX Plus 128 has two local audio outputs. Matrix sizes 1616 and smaller have four local audio outputs.

Matrix sizes 1632 and larger have eight local audio outputs.

NThese outputs are always outputs 1 and 2 (MTPX Plus 128), outputs 1 through 4 (matrix sizes up to 1616) or outputs

1 through 8 (matrix sizes 1632 and larger), with the same inputs tied to them as the TP output of the same number.

NEach local output has a volume control. See "Viewing and Adjusting the Audio Level" on page 3-7.

Remote control

iRemote port (switchers other than the MTPX Plus 128) — If desired, connect a control system or computer to the rear panel Remote RS-232/RS-422 port.
