Output video connector — Connect a projector or other high
resolution video device to this 15-pin HD connector.
e
Audio RS-232 output connector — Insert a 3.5 mm, 5-pole
captive screw connector into this jack for a mono audio and/or
an RS-232 serial output. See "Audio/RS-232 cable termination",
on page 2-12, to wire the connector for either or both formats.
N
The receiver auto-detects whether the audio/RS-232 pair
of the TP input is audio or RS-232, converts the signal
content accordingly, and outputs the appropriate signals
on the appropriate pins of this connector.
f
Level and Peaking controls —
Level control — Level alters the video output voltage to affect
the brightness of the displayed image. Adjust the knob while
viewing the displayed image to set the level/boost that provides
the best picture quality.
Peaking control — Peaking affects the sharpness of a picture.
Increased peaking can compensate for mid- and high-frequency
detail loss from low bandwidth system components or
capacitance in long cables. The minimum setting (at the
counterclockwise limit) provides no peaking. The maximum
setting (at the clockwise limit) provides 100% peaking. Adjust
this control to obtain the optimum picture sharpness.
g
Power LED — This LED indicates power is applied to the MTP.

C
Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the MTP. Identify the power cord negative lead by
the ridges on the side of the cord (figure 2-5).
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
W
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
C
The length of the exposed (stripped) copper wires
is important. The ideal length is 3/16" (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the direct insertion connectors
and could be pulled out.
N
Do not tin the power supply leads before installing them
in the direct insertion connector. Tinned wires are not as
secure in the connectors and could be pulled out.
