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.
N
The 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.
Do not connect this device to a computer data or
C
telecommunications network.
N
See the table on page 1-5 for recommended transmission
ranges.
N
You 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".
N
For best results, use a combined cable length of at least
50' (15 m) between the transmitter and the receiver on
the MTP SW6 output.
N
RJ-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.

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.
