Easy Setup Procedure

These easy-to-follow steps describe the general setup of the

P/2 DA2 MT. Refer to the previous application diagram.

1. If the P/2 DA2 MT is to be mounted using the mounting

brackets, please refer to the previous section.

2. Power off the computer and its local monitor.

3. Connect the computer’s VGA output to the 15-pin female VGA

input on the front panel of the P/2 DA2 MT.

4. If a local monitor is being used, connect the monitor to the 15-

pin local monitor output on the front panel.

5. Set termination pins (see

Front Panel DIP Switch Settings

below).

6. If audio is being input, connect the audio source to the 3.5 mm

audio input jack on the front panel. Refer to the audio

connector diagrams on the last page.

7. Connect the output display device, such as a projector, VGA-

compatible monitor, etc., to the 15-pin VGA data display

connector on the rear panel of the P/2 DA2 MT.

8. Connect an audio device to the 3.5 mm captive screw audio

output connector on the rear panel. Refer to the audio

connector diagram on the following page.

9. Connect the 9-volt power plug of the included power supply

into the power input jack on the rear panel.

Front Panel DIP Switch Settings

Set the two DIP switch pin positions (on/up or off/down):

Pin 4 Pin 11 Function

off off computer input pins 4 & 11 passed to

local monitor output connector

on on provide ID bit termination when no

local monitor connected

on off provide correct MAC 13” ID bit

termination

Rear Panel DIP Switch Settings

Set the Level/Peaking DIP switch On (up) to increase level and

peaking of the data display, otherwise, set the switch Off (down).

Operation1. Power on the computer and monitor.

2. Power on the output display device.

3. Power on the P/2 DA2 MT. The LED will light amber when the

power is on and will light green when the power is on and

there is an input present.

Description

The P/2 DA2 MT Distribution Amplifier can be mounted using the

included mounting brackets and screws. Audio input and output

connectors and an external DC power supply are also features of

the P/2 DA2 MT. See example application diagram below.

Front Panel

The front panel consists of a 2-color LED indicator (amber

indicates power On only, green indicates power On with video

signal present), a 3.5 mm female audio input jack, a 15-pin

female VGA input, a 15-pin female VGA buffered local monitor

output, and 2 DIP switches that set the input termination.

Rear Panel

The rear panel consists of a 9-volt power input jack, a Level/

Peaking DIP switch to control video level and peaking (data

display device only), a 15-pin VGA output connector, and a 3.5

mm captive screw audio output connector.

Mounting Bracket

The included mounting brackets are attached to the P/2 DA2 MT

using the 6 bracket screws, as shown on page 5. The unit may

then be mounted under a desk or some other suitable location

using the 4 wood screws (see mounting template). Optional

brackets are also available for vertical mounting (see mounting

template).
