A	DC power connector — Plug the external 12 VDC power supply
	into this 2-pole captive screw connector. See "Power supply

wiring" on page 2-9 to wire the connectors.

NThe remote power capabilities available with certain MTP models are not supported by this unit; the transmitter, switcher, and receiver must all be powered.

B	Input connectors — Connect up to six TP cables from
	transmitters to these RJ-45 female connectors. See “TP cable
	termination” on page 2-10 to wire the RJ-45 connectors.

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

NSee the table on page 1-5 for recommended transmission ranges.

NYou must configure the switcher for the appropriate content on the audio/RS-232 wire pair (pins 3 and 6) for each TP input. See the Audio/RS-232 TP input (wire pair 3 and 6) configuration SIS commands in chapter 3, "Remote Control”.

NFor best results, use a combined cable length of at least 50' (15 m) between the transmitter and the receiver on the MTP SW6 output.

NRJ-45 termination with CAT 5, CAT 5e, or CAT 6 cable must comply with the TIA/EIA T568A or TIA/EIA T568B wiring standards for all connections.

RJ-45 termination with Enhanced Skew-Free A/V UTP cable must comply with TIA/EIA T568A only.

	N For low resolution MTPs (S-video and composite video)
	used as the TP inputs, the MTP SW6 audio circuits are
	only compatible with the newer generation, mono audio
	models. See the MTP transmitter/ receiver to determine
	which MTP models you have.
C	Output connector — Connect one end of a terminated TP cable
	to this RJ-45 female connector.
	Connect the free end of the same TP cable from the switcher to
	the RJ-45 female connector on a compatible MTP receiver.
	See "TP Cable Termination", on page 2-10, to properly wire the
	RJ-45 connectors.
D	Pre-Peak switch — The Pre-Peak switch alters the TP signal
	output to correct for long cable runs. See the table on page 1-5
	for suggested switch settings based on the transmitted video
	format and transmission distance.
E	RS-232 Insert connector — For bidirectional RS-232 data that
	is routed from a common source to the TP output regardless
	of the selected input, connect a serial device to this 3.5 mm,
	5-pole captive screw connector. Figure 2-5 shows how to
	wire the connector.
	N For the RS-232 insert to be available on the TP output,
	it must be enabled via an SIS command or the Windows-
	based control program. See chapter 3, “Remote
	Control”, for details.
	N When the RS-232 insert is enabled, any content on the
	audio/RS-232 wire pair for the TP input tied to the
	output is disabled.
