SECTION 1. INTRODUCTION

1-1. GENERAL

The MV-40P Multi Viewer accepts up to 4 video input signals from such sources as color or black & white video cameras, and, in the split mode of operation, can display the 4 compressed video pictures simultaneously on one standard television monitor. Non-synchronous input signals from various different sources can be connected to the MV-40P. In addition, up to 6 characters can be superimposed onto each picture. Also individual picture scenes can be frozen in the split mode. With all these features, the unit is a highly cost-effective addition to any video system, and is also an easy-to-use extension to your system capabilities. The MV-40P is ideal for use in a wide range of applications, including surveillance security, medical treatment and educa­tion.

1-2. FEATURES

* In the normal mode, each camera scene is independently displayed on the monitor. Thus· the MV-40P can be utilized as a 4-channel video switcher.

* Up to 4 asynchronous PAL format signals can be input.

* In the split mode, 4 compressed pictures can be displayed simultaneously on the monitor.

* Four compressed pictures can be frozen either simulta­neously or individually.

* Resolution of compressed pictures - 256 x 256 dots (8bits).

* Built-in sync generator gives black background to those parts of the split display that do not have video signal input.

* ALARM display can be triggered by external signals.

* Up to 6 alphanumeric characters can be superimposed on each picture.

b. Inspection

Inspect the equipment to ensure that no damage has been sustained during shipment. If any damage is detected, notify the carrier and the distributor imme­diately.

c. Power Supply

This unit can be operated on 180 - 264 VAC, SO/60Hz. When a voltage within this range is used, no manual voltage change is required.

d. Ground

To protect operators from electrical shock, this unit is equipped with a 3-pin power cable. Therefore by simply connecting the unit to an AC outlet, the unit is grounded. If the power supply outlet is a 2-pin socket, use a 2-pin to 3-pin connector adaptor and ground the green wire (pig tail) of the adaptor or ground terminal of the connector panel.

e. Installation

Avoid using this unit in areas subject to extreme tem­peratures, high humidity, or excessive dust. Moderate air cooling is required for optimum operation of the unit. Ensure that no other equipment is located closer than 5 cm from the front or rear of this unit.

f. Table Top Unit

ThiS unit is equipped with rubber pads on the base plate for use as a table top unit.

g. Rack Mounting

For rack mounting, remove the rubber pads and attach the rack mount brackets included with the unit.

Notes 1) When the power is turned on, VIDEO OUT 1 and 2 show compressed split pictures and a black background is displayed on the areas of the d isplay that have no signal.

2) When a video signal is connected to VIDEO I N 1, the signals input through VIDEO IN 2 - 4 a re synchronized to the VIDEO IN 1 signal.

3) When no signal is fed to VIDEO IN 1, the unit works with internally generated sync.

4) Ei t he r color or black & white signals can be connected to VIDEO INs. However, when a black & white signal or non-standard color signal is con­nected to VIDEO IN 1, the output video signal becomes a non-standard color signal.

1) POWER switch When the switch is on, the LED will illuminate to show that power is supplied to the unit.

2) REMOTE/LOCAL The selection switch for REMOTE/LOCAL switch operation. When the power is turned

on, LOCAL status will be selected (green lamp is not lit) and all opera­tions are performed using the front panel switches. When the switch is pressed, the green lamp will light and the unit switches to REMOTE status. In the REMOTE stat us , all operations except character sett ing are performed through the REMOTE connector on the rear panel.

3) CHARACTER-SUPER switch

The character superimposition switch. When the power is turned on, the swi tch will be in the 'OFF' status, thus no characters are displayed on the screen. When the switch is pressed, the green lamp will light and the preset charac­ters are displayed on the input video image. However, if the CHARACTER-SET switch at the right is on (green lamp is lit), the characters are displayed even when the SUPER switch i s off.

4) FREEZE switches Freeze control switches. When the SET switch is off, any of these four switches can be pressed to freeze the corresponding compressed video images. A green light shows which switch is presently selected. when the SUPER and FREEZE switches are both engaged, the display characters will alternate between 'FREEZE' and preset characters.

Press the switch to activate the character setting controls. A green light will indicate that the switch is on. The preset characters will then be superimposed onto the video images and a flashing asterisk mark{*) indicates the character position where the character can be changed. The four switches to the right of this switch can then be used to select the desired characters and its position, as described below.

Character selection switches. when the SET switch 1s ON (green lamp is lit), these two switches can be used to select the desired characters.

Character position switches. When the SET switch is ON (green lamp is lit), these two switches can be used to move the position of the asterisk mark(*).

Video output selection switches for the VIDEO OUT 1. The green lamp lights up when the switch is selected. The four switches to the left of this switch can be used to select the desired video input signal for direct output. If a signal is not supplied to the VIDEO IN connector, there can be no signal output through VIDEO OUT 1. The switch to the extreme right selects the split screen output which is made up of the four compressed video images. If anyone of the four inputs has no signal, a black background is displayed in its place. Note : These switches will not control the VIDEO OUT 2 signal. When the power is turned on, the split screen switch is selected.
