Installation and Operation

Description

The P/2 DA2 Plus, P/2 DA4 Plus, and P/2 DA6 Plus are distribution amplifiers that accept video input from a VGA-UXGA compatible PC and distribute that signal to separately buffered outputs. Each output can be extended with Extron VGA-HR cables in 6', 15', 25', 50', 75', 100', 150', 200' and 250' lengths.

Examples of typical installations are shown in the diagrams on the following pages.

Installation

1.Power off the computer and its local monitor.

2.For optional rack mounting (four and six output only), mount the unit on one side of a 19" 1U Universal Rack Shelf (Extron part

#60-190-01). See the illustration below.

a.If feet were previously installed on the bottom of the case, remove them.

b.Mount the unit on the rack shelf, as shown below, using two 4-40 x 3/16 screws in opposite (diagonal) corners to secure the case to the shelf.

Use 2 mounting holes on opposite corners.

Installation and Operation, cont’d

5.Connect an LCD panel, a VGA-UXGA monitor, or a projector to the other output(s).

6.Connect power to the distribution amplifier.

7.Power on the local monitor, the computer, and display device(s).

Indicators and Controls

Power LED: Located on the front and rear panels of the P/2 DA4 Plus and P/2 DA6 Plus only. When illuminated, it indicates that the distribution amplifier is receiving power.

Video Gain toggle switch: (P/2 DA4 Plus and P/2 DA6 Plus only) The Video Gain switch is normally set to 0.7V (down). For installations with long output cable runs, the 1.0V (up) position will give a brighter picture.

Rack Mounting

After the distribution amplifier and its connected devices are powered up, the system is fully operational. If any problems are encountered, verify that the cables are routed and connected properly. For units with the Video Gain toggle switch, verify that the switch position is correct (refer to the previous Indicators and Controls section).
