P/2 DA2xi
P/2 DA2xi MT
The P/2 DA2xi and the P/2 DA2xi MT are distribution amplifiers
that accept video input from a VGA, XGA, or UXGA compatible
PC and distribute the signal to separately buffered outputs. Each
output can be extended with Extron VGA Mini-HR cables from 6'
to 250' in length. The MT model also has audio input and output.
Both models can be powered by newer computers compatible
with the new VESA standard using pin 9 of the VGA connector as
the +5VDC source. An external power supply is also provided
for use with older computers, where power is unavailable
through the VGA connector or the available power is inadequate.
Features
• Powered by computer — This unit can be powered by most
newer computers.
• Power/Signal LED — Green LED = power + signal. Amber
LED = power but no signal. Off = no power.
• Gain/Peak DIP switch — To compensate for longer cable runs.
• Out Imp DIP switch — Changes the output impedance to be
compatible with all projectors.
• Cable retention chain — To prevent a lost or misplaced input
VGA cable, the cable can be secured to the unit (either model)
with the supplied chain (attached to the right standoff nut of
the input VGA connector).
Only products in the VersaTools line can be mounted to a
VersaTools rack shelf.
Figure 2 — Mounting the P/2 DA2xi or P/2 DA2xi MT on
a rack shelf
1. Remove the rubber feet (if installed) and mount the unit on the
rack shelf, using two screws in opposite (diagonal) corners.
2. Install blank panel(s) or other unit(s) to the rack shelf.
3. Insert the shelf into the rack, and secure the shelf to the rack
using the supplied machine screws.
Furniture or projector mounting
Furniture mount or projector mount the unit using the mounting
kit (part #70-077-01, furniture [optional with the P/2 DA2xi,
standard with P/2 DA2xi MT] or #70-077-04, projector [optional
with both units]) as follows:
1. Attach the mounting brackets to the P/2 DA2xi or
P/2 DA2xi MT with the provided machine screws (figure 3).

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
1
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.
2
Video Input connector — Connect a computer’s VGA UXGA output to this connector.
3
Monitor connector — Connect a local monitor to this
connector.
4
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 [

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.
