DVI (Digital Visual
Interface)

DVI is a digital interface standard. DVI allows direct transmission of the PC’s digital data
without loss. This adopts the TMDS transmission system and DVI connectors. There are
two types of DVI connectors. One is a DVI-D connector for digital signal input only. The
other is a DVI-I connector for both digital and analog signal inputs.

While gamma has no effect on black or white, it does affect grey or mid-tones. If the

gamma is set too low, mid-tones will appear too light.

a monitor displaying moving images. They are indicated by reduced time measurements
in product specifications. Although cited, black-to-white-to-black response time is not
the ideal indicator of a monitor's ability to play moving images smoothly, since it doesn't
measure the transition time between gray-to-gray mid-tones included in all color images.
Therefore, gray-to-gray mid-tones response time is the better metric of a monitor's
performance to play motion pictures.

substances in electrical and electronic equipment". The six restricted substances are
lead, mercury, cadmium, hexavalent chromium, PBDE (polybrominated diphenylethers),
and PBB (polybrominated biphenyls). RoHS went into effect in July 2006 and applies
to most electrical and electronic equipment manufactured and imported into the EU. All

15 | Installation Instructions

1.6.1 Ergonomics

For optimum viewing it is important to ergonomically install the screen correctly.
An excessively dark or bright screen may affect your eyes. Adjust the brightness of the monitor according to the

environmental conditions.

1. Adjust the brightness of the monitor according to the environmental conditions.
Note For ECDIS applications, the minimum recommended viewing distance is as follows: (IEC62288, Part

7.5 Screen resolution), 46” TFT Pixel pitch: 0.53025 (H) x 0.53025 (W) [mm] = Recommended Viewing
Distance: 1.823 m

1.7 Connecting the Device

The power supply of the device works with 100-230 VAC and/or 24 VDC via the connectors provided.

1. Check whether the plugs for the DVI, VGA and CVBS signal are correctly plugged in and tightly fastened.

2. Connect the device to the power supply.

As soon as a valid signal is recognized, the source of the signal appears on the display screen.

Note The device should be allowed to warm-up for at least 30 minutes before you begin to do any calibrating
or adjustments.

2 Operation

This chapter describes MENU handling, RADAR settings, CALIBRATION and TROUBLESHOOTING.

2.1 OSD - Menu

The “On-Screen Display” (OSD) is a menu system shown on the display screen. All settings and adjustments to the
monitor can be made with the help of the menu system and the operating elements described.

The OSD Keyboard is placed at the front panel and is operated with four buttons (plus additional On/Off button). Two
status LED's indicate monitor operating status. The ambient light sensor placed at the left side is not implemented in the
monitor application. See Figure 9: OSD Keyboard on page 17.

Figure 9: OSD Keyboard

The OSD can be also operated with four buttons (plus additional On/Off button) that are connected via a special
interface. See Table 6: Interface for external keyboard on page 14.

Essentially there are two OSD menu's available:

1. Quick OSD menu:

The most important parameters, e.g. back-light brightness, or signal source can be preset here for quick access.

2. Main OSD menu:

All settings, configurations, measurements and calibrations can be made here.

Note Blocked OSD access (OSD lockout).

• When OSD lockout is enabled, an access code is needed to get into the OSD every time you try to open it.

• After entering the access code, the OSD opens; however, the OSD lockout remains active.

• To permanently enable OSD, the OSD lockout has to be deactivated in the OSD “SETUP”.
Note Delayed monitor On/Off-Sequence.

• When switching “On” or “Off” the monitor via the OSD press the button for around 2...3 seconds.

• This prevents the monitor from switching “Off” if the operator touches the On/Off-button unintentionally.

2.2 LED Indicator

The two LED's on the front OSD keyboard indicate following status:

2.3 Quick OSD Menu

Use the quick OSD Menu to quickly get started:

1. Press the ▼ or ▲ button to call up the “Backlight” Quick OSD Menu to change backlight brightness and also to change

backlight brightness.

Note 0.5 .. 400 cd/m² if “Backlight Controller is set to “On”, or 0 .. 100 if “Backlight Controller is set to “Off”.

2. Press the ↵ button to call up the “Signal Source” Quick OSD Menu or the PiP OSD menu if monitor is in PiP-mode.

3. Press the ▼ or ▲ button to select the input source and quit your choice by pressing the

↵button.

This sub-menu shows the detailed results of the internal monitor self-test. It is used by service personnel for purposes of
analysis.

Note There are no detailed results shown!

2.13 ECDIS - Radar Settings

This monitor features an ECDIS-compatible operating mode to display colors corresponding to the image content
(nautical charts) according to the specifications of the IHO (International Hydrographic Organization).

This operating mode can be enabled only when the following preconditions are in place:

• The monitor is calibrated with gamma 2.2 and the white point x=0.300, y=0.310.

• The back-light sensor is calibrated.

These requirements have been met at the time of delivery.

Note When ECDIS mode is enabled, no changes can be made to the color temperature, gamma and back-light
controller.

Note For the correct representation of ECDIS image files, there are corresponding color tables for the three
operating conditions of DAY, DUSK and NIGHT. The respective RGB values for the color tokens from the S-52
"Presentation Lib" are recorded in these tables.

Note To obtain these tables, please contact ALPHATRON MARINE.

2.14 Monitor Calibration

To be able to use the monitor as an ECDIS-compliant display it has to be set as described in ECDIS - Radar Settings on
page 27.

Prior to calibration operate the monitor for at least two hours at a medium back-light brightness level. Place the color
sensor in the middle of the screen, see Figure 11: Color Sensor placement on page 27.

Figure 11: Color Sensor placement

27 | Operation

A color sensor that is connected to the DV4624 via the RS232 interface is required to perform this calibration. Control of
the calibration process is done through the monitor itself and can be started using the OSD. No additional hardware or
software is necessary.

All necessary calibrations were done at the factory. Recalibration may be required to compensate for variations in color
and gamma characteristics, due to e.g. age, and to ensure ECDIS compatibility.

Note Start individual calibrations like Analog RGB, Back-light Sensor and Gamma Color in the OSD sub-menu
“Picture 2 / Calibrate and Measure”, see Table 14: Main menu - Picture tab 2 (DVI-1, DVI-2, RGB-1, RGB-2,
CVBS) on page 20.

2.14.1 Calibrating the RGB Input Channel RGB-1 (VGA) and RGB-2

1. Execute this adjustment in the final application to compensate for the influences from transfer cable and graphic

cards.

Note The signal differences between red, green and blue signals are compensated for to make this
adjustment.

2. Display a white image (100%) on an imaging computer system.

3. The OSD performs the calibration procedure with the corresponding instructions.

2.14.2 Calibrating the Back-Light Sensor

The back-light sensor in the device ensures that the cd/m² brightness level set in the OSD is correctly transmitted and
remains unchanged during operation.

1. Use an external brightness measuring device, to run the calibration.
Note The OSD differentiates between brightness level set in the OSD and the Color Sensor.

2. The OSD performs the calibration procedure with the corresponding instructions.

2.14.3 Calibrating Gamma & Color

Gamma and color (white point) must be correctly calibrated to operate the monitor in the ECDIS or radar mode.

1. Preset the correct color coordinate (white point) of X=.300, Y=.310 and a gamma of 2.2.
Note If other values are used, the monitor cannot be set in the ECDIS or radar mode.

2. The OSD performs the calibration procedure with the corresponding instructions.

2.15 Serial Communication Interfaces

The monitor has several serial interfaces that are controlled via the monitor or can be used to retrieve status information,
like:

• RS-485 and RS-422

• RS-232

• USB

• Ethernet

Different protocols are available for communication via these interfaces.

1. Communication via the RS232, RS485 and USB is based on the MODBUS standards.
Note The format is identical for all three interfaces.

2. For communication via the Ethernet interface, the SNMP protocol is available.

28 | Operation

Note The detailed description of each of the communication protocols is available in separate documents

available from ALPHATRON MARINE
