Installation, cont'd
Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connector and could be
pulled out.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
As an alternative, an Extron P/S 100 Universal 12 VDC Power
Supply, part #60-357-01, can power up to ten Extron 12 VDC
devices using only one AC power connector.
Signal input connections
Computer input connectors — Connect the
2
high resolution or computer inputs (VGA,
SVGA, XGA, SXGA, or UXGA) to these
female, 15-pin HD connectors. The number of inputs available
varies with the switcher model.
Input only sync signals, no video signals, on the sync
pins, 13 and 14.
For component video, use the R (R-Y) and R return pins
(pins 1 and 6), G (Y) and G return pins (pins 2 and 7),
and B (B-Y) and B return pins (pins 3 and 8).
For S-video, use the R, R return (C-chroma), G, and G
return (Y-luma) pins.
For composite video, use the G pin and the associated
return pin.

Audio input connectors — Plug a 3.5 mm

stereo audio plug into this jack for
unbalanced audio input. Wire the plug as shown in figure 2-8.
The number of inputs available varies with the switcher model.
Figure 2-8 shows a typical audio connector, which
consists of the tip, ring and sleeve. The ring, tip, and
sleeve wires are also shown on the audio output captive
screw audio connector diagram, figure 2-9.

The selected stereo audio input is summed and output on the
TP cable as mono audio. The selected input's audio is also
available on a captive screw connector in its stereo, unsummed
form.
Signal output connection
Output connector — Connect one end of a terminated TP cable
4
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 the MTP R 15HD A or
MTP RL 15HD A receiver.
See TP Cable Termination, on page 2-11, to properly wire the
RJ-45 connectors.
Pre-Peak switch — The Pre-Peak switch alters the TP signal
5
output to correct for long cable runs. See the table on page 1-4
for suggested switch settings based on the transmitted video
format and transmission distance.
