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.

Connections, Indicators, and Controls

Figure 4 — Front and rear panels

Power/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.

Video Input connector — Connect a computer’s VGA -

UXGA output to this connector.

Monitor connector — Connect a local monitor to this

connector.

Power 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.

Figure 5 — Power connector wiring

CAUTION

When connecting the power supply, voltage polarity

is extremely important. Applying power with

incorrect voltage polarity could damage the power

supply and the amplifier. 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.

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

output [

], not the “monitor” output [

]). 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 output device has no picture, switch to the other position.

Video output connector — Connect the video output

device, such as a projector, LCD panel, or monitor, to this

connector.

Audio input connector (MT model only) — Plug a

3.5 mm, mini jack audio cable from the computer’s sound

card into this connector.

Audio output connector (MT model only) — Insert a

3.5 mm, 5-pole, captive screw audio connector into this

connector. Wire the connector as shown below.

Figure 6 — Audio connector wiring

CAUTION

Connect the sleeve to ground (Gnd). Connecting the

sleeve to a negative (-) terminal will damage the

audio output circuits.

Local monitor cable assembly — Use this cable assembly

to connect the local monitor (video) and speaker (audio) to

the unit. The chain is used to attach the cable to the unit,

to prevent the cable from being lost or misplaced.
