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 15­pin local monitor output on the front panel.

5. Set termination pins (see
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, VGA­compatible 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

on on provide ID bit termination when no

on off provide correct MAC 13” ID bit

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).

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).

Operation

1. 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.
