Installation

2. If feet were previously installed on the bottom of the unit, remove them.

3. For furniture mounting, hold the unit with the attached

brackets against the underside of the table or other furniture. Mark the location of the screw holes of the bracket on the mounting surface.

4. For furniture mounting, drill 3/32” (2 mm) diameter pilot holes, 1/4” (6.3 mm) deep in the mounting surface at the marked screw locations.

5. For furniture mounting, insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 1/4” of the screw head protrudes.

6. For furniture mounting, align the mounting screws with the slots in the brackets and place the unit against the surface, with the screws through the bracket slots.

7. For furniture mounting, slide the receiver slightly forward or back, then tighten all four screws to secure the unit in place.

8. For projector mounting, secure the unit to a projector mount or other surface by inserting the mounting bolt through the bracket’s slotted hole.

1Power/Signal indicator LED — When illuminated green, this LED indicates that the distribution amplifier is receiving both power and a computer signal. When illuminated amber, it indicates that the distribution amplifier is receiving power but no computer signal. If the LED is off when the distribution amplifier is connected to a PC with power on, it indicates that an external power supply is required.

2Video Input connector — Connect a computer’s VGA - UXGA output to this connector.

3Monitor connector — Connect a local monitor to this connector.

4Power connector — Plug the external 12V power supply only when needed (see Power/Signal indicator LED above) into this 2-pole captive screw connector. The power supply is included with the unit and is shipped with a plug installed. If you need to cut the power cord to a different length and reinstall the plug, refer to figure 5 and the following notes.

CAUTION	When connecting the power supply, voltage polarity
	is extremely important. Applying power with
	incorrect voltage polarity could damage the power
	supply and the P/2 DA2xi. Identify the power cord
	negative lead by the ridges on the side of the cord.

Do not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could pull out.

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

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

5 2-bank DIP switch — (These switches only affect the video

output ( 6 ), not the “monitor” output ( 3 )). The Gain/

Peak DIP switch should be on (up) when output cable is

over 100’ (30.5 m). The Out Imp DIP switch changes output impedance. If all connections and operations are correct, yet the projector has no picture, switch to the other position.

6Video output connector — Connect the video output device, such as a projector, LCD panel, or monitor, to this connector.

7Audio input connector (MT model only) — Plug a

3.5mm, mini jack audio cable from the computer’s sound card into this connector.

8Audio output connector (MT model only) — Insert a

3.5mm, 5-pole, captive screw audio connector into this connector. Wire the connector as shown below.
