Section 1 1.1 INTRODUCTION About LCD Monitors What you gain by using an LCD monitor in your industrial controls LCDs are the future of display technology. Although CRTS have dropped in cost significantly, they 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.
1.2 Product Safety Precautions 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.
1.4 On Installation 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.
Section Display Setup 2 2.1 2.2 VT190 Military/Marine Series Display Features ⇒ Capable of displaying unlimited colors in a continuous spectrum. The high contrast LCD enhances the image with no geometric distortion. ⇒ The VT190 Military / Marine Series directly accepts an analog 5 wire RGB with separate H/V sync or 4 wire RGB with separate combined sync or 3 wire SOG.
2.4 Connecting the Display When connecting the monitor to an analog signal source, it is necessary to use a cable that terminates on the monitor end with an HD-15 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.
2.5 Signal Connections Cont. Optional Video Cable Options HD15 to HD15 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.
2.6 Power and Ground Connections 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.
Section Getting Started 3 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. 3.
3.2 Setting up the Video Source The monitor can be adjusted to display a wide range of video formats, depending on the capabilities of the video source (typically a PC graphics card) and the requirements of the application. Once adjustments have been made for a given format, they are remembered, and readjustment is automatic when switching between remembered formats.
3.2 Setting up the Video Source Cont. The following table provides a good guideline for estimating the capabilities of a given video source or for determining the memory requirements for a new source. Video RAM Requirements for Various Display Resolutions and Color Depths* Color Depth / Resolution 256 colors (8 bpp) 65536 colors (16 bpp) 16777216 colors (24 bpp) 640x480 0.5MB 1.0MB 1.0MB 800x600 0.5MB 1.0MB 1.5MB 1024x768 1.0MB 1.5MB 2.5MB 1152x864 1.0MB 2.0MB 3.0MB 1280x1024 1.5MB 2.
3.3 Adjusting the Monitor For details about navigating the OSD menu system, see the following section. This section discusses the use of the OSD menus to optimize the monitor for display of a given video format. An initial adjustment of the monitor should first be made by pressing the AUTO button. Afterwards, if additional adjustment is thought to be necessary, the following procedure can be used. 1. Set scaling mode. Press any one of the Up/Down/Right/Left buttons to bring up the Quick Menu.
3.4 Navigating the OSD in detail The integrated On-Screen Display (OSD) is used to control various display and system parameters. The OSD provides a system of setup menus that are accessed with the controls shown below. SOURCE MENU DOWN UP LEFT AUTO RIGHT Figure 3 – OSD Controls Button Use SOURCE (EXIT) The first button press displays the current source.
3.5 Picture Submenu The Picture submenu presents a list of items that depends on the selected video source (digital, analog RGB, S-video, or composite video). The current version of the product supports only an analog RGB source.
3.6 OSD Submenu The OSD submenu contains the following functions: Navigation Buttons Menu Item Explanation H Pos Note that H POS and V POS refer to the position on the screen of the OSD itself, not to the position of the image from an external source. V Pos UP OSD Timeout The OSD TIMEOUT period is the time the OSD will remain on the screen in the absence of user input. If there is no user input for the duration of the timeout period, the OSD will disappear.
3.7 Utility Submenu The Utility submenu contains the following functions: Navigation Buttons Menu Item Explanation Freeze Frame This selection is used to “capture” the image content currently being displayed. Updates of the display based on subsequent signal changes at the video inputs are temporarily halted. This control could be useful, for example, in conjunction with a Print Screen operation. UP Reset Select with caution.
3.8 Quick Menu The Utility submenu contains the following functions: Navigation Buttons Menu Item Explanation Brightness On a CRT monitor, the brightness control is really a black level adjustment and is set so that the background raster is just cut off when a black screen is displayed. On an LCD monitor, the brightness control is a control of the backlight luminance level. Both black and white levels change with changes in backlight luminance.
Section 4 4.1 TOUCH SCREEN Introduction Touch screens are a common means to interface operator inputs to a system. The universal standard of Windows GUI (Graphical User Interface) has significantly increased the use of touch screens. There are four main touch technologies. The technologies are resistive, surface acoustic wave (SAW), capacitive, and infrared (IR). Each touch technology has advantages and disadvantages based on different user applications. 4.
Section Troubleshooting Tips 5 Front panel power • indicator does not come on • when power switch is set to “on” position. • Check for a loose, damaged, or disconnected power cord. Check for power available at the AC receptacle. (Plug in a known good lamp.) Check the monitor’s AC fuse. (Refer to the section below on fuse replacement.) Monitor is powered on, but • has no display • Check for a loose, damaged, or disconnected power cord. Ensure that the luminance control is not turned all the way down.
Section Cleaning and Maintenance 6 Cleaning Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked) with a mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the screen surface to avoid scratching it with accumulated grit. Note: The solvent (a 50/50 mixture isopropyl alcohol and water) should be applied only to the cloth, and not directly on the monitor screen. Do not use paper products as they may scratch the surface.
