CHAPTER 1: Installation

Introduction

Overview

The HDM-320-4K-TT monitor sets a new standard in UltraHD LCD monitors for broadcast and professional video applications. It provides a 32", 3840 x 2160 resolution, 16:9 format, 60Hz refresh, anti-glare IPS LCD screen. All video formats are scaled to fit on the screen in the highest quality using 12-bit digital processing, precision scaling and gamma correction to produce the best images possible.

Features

The HDM-320-4K-TT audio/video monitor is designed for confidence monitoring of four 3G/HD/SD-SDI inputs. 2SI Interleave or Quad-Link 4K video can be monitored using the four HD-SDI inputs together. Input signals are easily selected and displayed. Two to sixteen audio channels may be selected for visual monitoring on bar graph style level meters. On screen marker displays can be enabled on this full-featured monitor. Stereo speakers provide audio monitoring. A headphone jack is also provided for external audio monitoring.

Parameters are selected and adjusted using an On Screen Display (OSD) Menu. Monitor management settings can also be made with a web browser over Ethernet using the integral web server. The monitor can contain up to four user definable configurations which can easily be recalled whenever necessary.

Safety

1. Protect the power cord from being walked on or pinched, particularly at plug connection on the equipment and at the socket.
2. Use only the attachments/accessories specified by the manufacturer.
3. Unplug the equipment during lightning storms or when unused for long periods of time.
4. Refer all servicing to qualified service personnel. Servicing will be required under all of the following conditions:

a. The equipment has been damaged in any way, such as when the power-supply cord or plug is damaged.
b. Liquid had been spilled or objects have fallen onto the equipment.
c. The equipment has been exposed to rain or moisture.
d. The equipment does not operate normally.
e. The equipment has been dropped.

Safety Symbols

The symbol to the left warns of electric shock hazard inside the unit. Disconnect the power cord before removing access panels when installing upgrades. Only qualified service personnel are to operate the equipment with covers removed, and are to exercise caution to avoid personal injury.

Mounting

The HDM-320-4K-TT is designed to be placed on a tabletop or other flat surface. Position either unit at ear/eye level for best high frequency response and visual observation of the display screen. Please adhere to the following clearances:

Table 1-1: Recommended Clearances

Heat Dissipation

The ambient temperature near the product should not exceed 40^ Celsius ( 104^ Fahrenheit). When rack mounting, adjacent devices can be rack mounted in proximity to the unit if this temperature is not exceeded. Otherwise, allow a 1RU (1.75"/44.45mm) space above and below the unit for air circulation. For table top operation, in warm environments, allow an inch of space above and below the unit for air circulation.

Important

To reduce noise, the monitor does not have any fans. As a result, the heat generated by the audio amplifiers, power supplies, and other components is vented by slots in the back of the unit. Therefore, as a safety precaution, you must allow proper ventilation on these surfaces.

Sympathetic Ωibration

Sympathetic vibration from other equipment (cables, etc.) in the rack may be serious enough to interfere with the unit's sound quality. If you experience sympathetic vibrations, use thin card stock, felt, foam, or weather-stripping between the vibrating surfaces. Tie loose cables securely with cable ties.

Mechanical

The sturdy chassis is very shallow from front to back making it very stable on its table stand. It can be tilted forward or backward for viewing, if necessary. The weight of internal components is distributed fairly evenly around the unit.

Electrical Interference

Be careful to avoid mismatched cable types and other similar causes of undesired reflections in digital signal systems. If severe enough, such reflections can result in corruption of the digital data stream. As with any audio equipment, maximum

Compliance

FCC

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at their own expense.

CHAPTER 4: Using Network Control

The HDM-320-4K Web GUI allows you to customize the monitor configuration to perfectly suit your needs. The following setup steps are not necessary if you intend to use the HDM-320-4K in its default configuration or if you only make configuration changes using the OSD menus. However, the HDM-320-4K Web GUI network control is ideal for configuring difficult to access monitors.

Web Browser / Control Device

Any web browser application running on any networked device such as desktop or laptop computer, tablet, or smart phone can be used with the HDM-320-4K Web GUI.

If a tablet without a physical network connector is to be used, it needs to be linked to a copper LAN through a Wi-Fi adaptor.

Phones are not recommended due to their smaller screen size, which would require more scrolling.

The Chrome® web browser is recommended for speed and compatibility.

First Time- IP Assignments

The HDM-320-4K operates with a static (fixed) IPv4 address. The address will be 192.168.1.86 when received from the factory or when reset at the front panel. This is shown in Figure 4-2. The IP address will need to be changed to some other address to be compatible with the customer's network address assignments. Go to

Figure 4-1: Host IP Settings

Internet Protocol Version 4 (TCP/IPv4) Properties General You can get IP settings assigned automatically if your network supports this capability. Otherwise, you need to ask your network administrator for the appropriate IP settings. Obtain an IP address automatically Use the following IP address IP address: 192 . 168 , 1 , 99 Subnet mask: 255 . 255 , 255 , 0 Default gateway: 192 . 168 , 1 , 1

After making an IP address change such as this, close the control panel and reboot the host computer to be sure the change takes effect.

Make the final address, mask and gateway changes in the HDM-320-4K System setup page.

Management Interface

The Management Interface browser window is shown in Figure 4-2. Enter the IP Address of the monitor into the address bar on your browser and press the Enter key to access the web server. The settings in the Web GUI apply to the system in general, regardless of which input source is selected.
