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.

Power supply wiring

Figure 2-5 shows how to wire the power connector.

NThe 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 —

WrapTie

SECTION A–A

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.

CPower 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.

WThe two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.

CThe 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.

NDo 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.
