Setting the internal jumpers  

Installing the P/2 DA2 D  

The jumpers (J2 and J6) inside the distribution amplifier are set  

The P/2 DA2 D is a wall-mounted product and can be mounted  

into an electrical wall box. These instructions include site  

preparation, wall box installation, and the mounting of the  

distribution amplifier in the wall box.  

at the factory for output to a local monitor. However, you can  

direct output to a data display by resetting the jumpers. Follow  

these steps and the illustration below to change the jumper  

settings. In some instances where DDC communication is  

required between the display device and the computer’s  

graphics card, pins 15 (J2) and 12 (J6) will carry that information.  

N

The P/2 DA2 D must be installed into an Underwriters  

Laboratories (UL) approved electrical wall box. The box  

is not included with the distribution amplifier; the  

installer is responsible for obtaining/installing the box.  

C

Changes to internal jumper settings must be  

performed only by authorized service personnel.  

Preparing the site and installing the wall box  

1.  

Disconnect the power cable, then disconnect the output  

and audio cables from the rear panel of the distribution  

amplifier. Next, remove the rear cover by removing the  

two front panel screws. See “P/2 DA2 F wall mount  

installation” in this chapter for screw locations.  

Choose a location that allows cable runs without interference.  

Allow enough depth for both the wall box and the cables. You  

may need to install the cables into the wall or conduits before  

installing the distribution amplifier.  

The distribution amplifier can be installed in a standard one-  

gang electrical wall box. The installation must conform to  

national and local electrical codes. A dimensional drawing and a  

cutout template of the distribution amplifier are provided in  

appendix A of this manual.

.

Using a pair of tweezers or needle-nosed pliers, set  

jumpers J2 and J6, as shown below in figure 2-10.

Be sure you are electrically grounded before  

touching any circuit board components.  

•

Connect pins 1 and 2 on both jumpers (factory default)  

to output to the 15-pin female local monitor connector  

on the front panel.

The cutout template of the P/2 DA2 D shown in  

appendix A is not full size. Pay attention to the  

measurements shown in the template.  

or  

1.  

Mark the guidelines for the opening on the wall.  

•

Connect pins 2 and 3 on both jumpers to output to the  

rear 15-pin female output.  

•

If the distribution amplifier will be installed in a wall  

box, place the box against the installation surface and  

draw a line on it around the outside of the box.  

•

If the distribution amplifier will be installed without a  

wall box (fastening it directly to the wall), measure and  

mark the surface for the cutout area indicated in the  

cutout template.

.

Cut out the material from the marked area.

or the distribution amplifier (if no box is used) into the  

opening. Enlarge or smooth the edges of the opening if  

needed.
