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. Switch to on (up) when output cable is over 100’ (30.5 m).
• Out Imp DIP switch — Changes the output impedance to be compatible with all projectors.
Installation
The P/2 DA2xi and P/2 DA2xi MT can be mounted on a rack shelf, under a desk or tabletop, or on a projector bracket.
Rack mounting
For optional rack mounting, mount the P/2 DA2xi or P/2 DA2xi on a VersaTools 19" 1U Rack Shelf (part #60-190-20) or a standard Universal 1U Rack Shelf (part #60-190-01) as shown in figures 1 and 2, respectively.
Only products in the VersaTools line can be mounted to a VersaTools rack shelf.
Figure 2 — Mounting the P/2 DA2xi and P/2 DA2xi MT on the standard 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 optional mounting kit (part #70-077-01, furniture, or #70-077-04, projector) 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.
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
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.
