About LCD Monitors

What you gain by using an LCD monitor in your industrial controls

are the future of display technology. CRTs, although they have dropped in cost

significantly, do not offer the performance, reliability, and mounting options

available with LCDs. LCD monitors consist primarily of an LCD, Video Board

and a Back Light video. The LCD determines to a large extent the viewing

angle, brightness and contrast. Beyond that it is the function of the video board which converts the analog

RGB (Red, Green, Blue) signals from a standard video card to a high quality, digital RGB that the LCD

can display.

Recently the video card has taken on a new role. It is the responsibility of this device to “scale” a

particular video resolution to the “native” resolution of the LCD. Simply, consider that a computer is

putting out a VGA [640x480] resolution signal, yet the LCD that is connected is an XGA [1024x768]

display. The displayed picture would be in the center 1/3 of the LCD. With the introduction of the

scaling engine. The converter will mathematically recalculate the 640x480 to 1024x768. This may sound

simple but it is in fact a complex algorithm that adjusts for different aspect ratios and pixel alignment,

essentially smoothing text and graphics to produce a picture that is pleasant to the eye.

Product Safety Precautions

1.2

This unit has been engineered and manufactured to ensure your personal safety,

however improper use may result in potential electrical shock or fire hazards. In order

to allow the proper operation of all safeguards incorporated in this display, observe the

following basic rules for its installation, use, and servicing.

1.3 On Safety

Use only the power cord supplied with the unit. In case you use another power cord, make sure

that it is certified by the applicable national standards if not being provided by the supplier. If

the power cable is faulty in any way, please contact the manufacturer or the nearest authorized

repair service provider for a replacement. The power supply cord is used as the main

disconnection device. Ensure that them socket-outlet is easily accessible after installation.

Operate the display only from a power source indicated in the specifications of this manual or

listed on the display. If you are not sure what type of power supply you have, consult with your

service or maintenance department. Overloaded AC outlets and extension cords are

dangerous. So are frayed power cords and broken plugs. They may result in a shock or fire

hazard Call your service technician for replacement.

Do not Open the Display.

♦ There are no user serviceable components inside.

♦ There are Dangerous High Voltages inside, even when the power is OFF.

♦ Contact your dealer if the display is not operating properly.

To Avoid Personal Injury :

♦ Do not place the display on a sloping shelf unless properly secured.

♦ Use only a stand recommended by the manufacturer.

♦ Do not try to roll a stand with small casters across thresholds or deep pile carpets.

To Prevent Fire or Hazards:

♦ Always turn the display OFF if you leave the area for more than a short period of time.

♦ Do not drop or push objects into the display's cabinet openings. Some internal parts carry

hazardous voltages.

♦ Do not add accessories that have not been designed for this display.

♦ During a lightning storm or when the display is to be left unattended for an extended period

of time, unplug it from the wall outlet.

17.0” PowerVue User Guide 150-059

Do not allow anything to rest upon or roll over the power cord, and do not place

the display where the power cord is subject to damage.

Do not use this display near water such as near a sink, in a wet location where there is

standing water. Displays are provided with ventilation openings in the cabinet to allow the

release of heat generated during operation. If these openings are blocked, built-up heat can

cause failures which may result in a fire hazard.

Therefore, NEVER:

♦ Block any ventilation slots.

♦ Place the display in a built-in enclosure unless proper ventilation is provided.

♦ Cover the openings with cloth or other material.

♦ Place the display near or over a heat source.

Do not rub or strike the Active Matrix LCD with anything hard as this may scratch,

mar, or damage the Active Matrix LCD permanently.

Do not press the LCD screen with your finger for a long time as this may cause

some afterimages.

Some dot defects may appear as Red, Green or Blue spots on the screen.

However, this will have no impact or effect on the display performance.

If possible, use the recommended resolution to obtain the best image quality for

your LCD display. If used under any mode except the recommended resolution,

some scaled or processed images may appear on the screen. However, this is

characteristic of the fixed-resolution LCD panel.

1.6

Unplug the display before cleaning the face of the display screen. Use a 50/50 mix of

Isopropyl alcohol and water. Apply with a slightly damp (not wet) lint free cloth. Do not use an

aerosol directly on the display screen because over-spraying may cause electrical shock.

Do not throw away the carton and packing materials. They make an ideal container in which to

transport the unit. When shipping the unit to another location, repack it in its original material.

17.0” PowerVue User Guide 150-059

All Military / Marines Displays accept both digital and analog analog RGB video signals at an

integrated connector (DVI-I). S-video or NTSC/PAL composite video signals are accepted at the

DIN connector or RCA receptacle respectively. When multiple sources are connected to the

monitor simultaneously it is possible to switch between sources using the front panel SOURCE

button. (See the following chapter on operator controls for more details.)

Digital or Analog RGB Input

When connecting the monitor to a digital signal source, it is necessary to use a cable that

terminates on the monitor end with a DVI-I connector that mates to the monitor’s connector, and on

the source end with a DVI connector appropriate to the source – usually a DVI-D connector.

When connecting the monitor to an analog signal source, it is necessary to use a cable that

terminates on the monitor end with a DVI-I connector that mates to the monitor’s connector, and on

the source end with an HD-15 connector or with some combination of three to five BNC

connectors, as appropriate to the source.

Provided the correct cable is used, the monitor will automatically sense and adapt to any analog or

digital signals applied. In the case of analog signals, the monitor will automatically sense and

adapt to the sync type (sync-on-green, composite separate sync, or separate horizontal and

vertical syncs).

Please refer to the following figures for location of the DVI-I connector on the monitor’s rear panel.

This cable should be used when connecting the monitor to a signal source that provides analog

RGB outputs by way of an HD-15 connector.

HD-15 to 5 BNC

This cable should be used when connecting the monitor to an analog source that provides RGB

video by way of BNC connectors. There are three possible wiring schemes, depending on the

type of sync supplied by the source. The DVI-I to BNC cable can be used with all three schemes.

When the source provides composite sync on green, only three of the cable’s five BNC connectors

are used. When the source provides RGB video and separate composite sync, four of the cable’s

five BNC connectors are used. When the source provides RGB video and separate horizontal and

vertical sync, all five of the cable’s BNC connectors are used.

AC Power

A monitor equipped for operation on AC power should be connected to a single-phase power

source providing 115 to 230VAC nominal (85 to 264VAC) at 47 to 66Hz, or 400Hz.

Connection is made by way of an IEC power cord at the monitor’s power input connector, or by

way of a military style connector, when that option is specified.

DC Power

A monitor equipped for operation from a DC power source should be connected to the DC

main using UL approved #10 stranded wire. The wire should use properly color-coded

insulation.

2.6 Power and Ground Connections

WARNING: To ensure against fire or shock hazards, the monitor chassis should be con-

nected to an earth ground by a path that is independent of the power cord. While the AC

power cord provides a ground wire, the power cord ground can be defeated by use of an

extension cord or 3-prong to 2-prong AC adapter, and it can be rendered ineffective by im-

proper wiring of the AC receptacle.

NOTE: To minimize ground loop induced “noise” on the video inputs, it is good practice to

connect the monitor’s AC power cord to the same receptacle that supplies power to the video

source.

GETTING STARTED

Section

3.1 Operator Controls and Indicators

Operator controls include a power switch (an option), a button panel for accessing the setup

menus (OSD), and a luminance control. The VT170 Military / Marine Series monitors have

an LED to indicate power on. Figure 2 show a drawing of the VT170RM to illustrate the layout.

• The power switch controls main power to the monitor. Power on is indicated by an

LED next to the switch.

• The OSD controls are discussed in detail in a following section.

• The luminance control controls the backlight. The range of the control is determined

by the brightness setting made with the OSD.

The monitor is pre-aligned at the factory. However, minor adjustments are usually necessary

following installation to optimize the monitor’s performance with a particular video source and

particular video formats. This section of the manual describes the operator accessible controls that

allow for such adjustment. It goes on to describe a typical setup procedure.
