Safety Information
Safety Information
1. Save the carton and packing materials whether or not the unit arrives in good condition. If you ever need to ship the unit, use
the original factory packing.
2. Read all documentation before operating your equipment. Retain all documentation for future reference.
3. Follow all instructions printed on the unit chassis for proper operation.
4. Do not spill water or other liquids into or on the unit, or operate the unit in liquid.
5. Make sure power outlets conform to the power requirements listed on the back of the unit.
6. Do not use the unit if the electrical power cord is frayed or broken. Route the power supply cords so that they are not likely
to be walked on or pinched by items placed upon or against them. Pay particular attention to cords, plugs, convenience
receptacles, and the points where they exit from the appliance.
7. Always operate the unit with the AC ground wire connected to the electrical system ground. Be careful not to defeat the
grounding of a piece of equipment.
8. Voltage must be the same as that printed on the rear of the unit. Damage caused by connection to improper AC voltage is
not covered by warranty.
9. Power off and disconnect the unit from the voltage before connecting any equipment.
10. Do not leave the unit on unstable surfaces.
11. Do not use the unit near stoves, heat registers, radiators, or other heat-producing devices.
12. Do not block the fan intake or exhaust ports. Do not operate the equipment on a surface or in an environment that may
impede the normal flow of air around the unit, such as a bed, rug, carpet, or completely enclosed rack. If the unit is used in
extremely dusty or smoky environment, the unit should be periodically “blown free” of foreign matter.
13. Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages. There are no user-serviceable
parts inside.
14. Do not drive the inputs with a signal level greater than that required to drive the equipment to reach full output.
15. When you are not using the unit, unplug the power cord of the equipment from the outlet.
16. Refer servicing to qualified service personnel when:
A. The power supply cord or the plug is damaged.
B. Liquid has been spilled into the equipment.
C. The equipment has fallen.
D. The equipment has been exposed to rain.
E. The equipment does not appear to operate normally, or exhibits a change in performance.
F. The equipment has been dropped, or the enclosure damaged.

Chapter 2: Overview
2. Overview
2.1 Introduction
The AVSC-7DA-HDMI is a video graphics scaler that accepts seven types of signals: analog video, S-Video, component video, VGA,
DVI, HDMI, and DisplayPort signals. It scales the input signals into either VGA or HDMI signals, supporting higher full HD
resolutions of 480i/p, 720p, and 1080i/p. The scaler is designed to solve problems of compatibility between source devices and
monitors. Use it to deliver one single image on a TV wall. In addition to the front panel buttons and the IR remote control, users
may control the scaler using a PC through the RS-232 serial port or Ethernet port.
2.2 Features
• Compliant with HDMI 1.4, DVI 2.0, and HDCP 2.0.
• Input support: Analog: analog video, S-Video, composite video, VGA;
Digital: DVI, HDMI, and DisplayPort
• Output support: VGA and HDMI 1080p with deep color 36-bit
• Output audio support: S/PDIF, stereo audio
• Supports a wide range of HD resolutions ranging from XGA to WUXGA 1920 x 1200 to HDTV/DTV resolutions 480i/480p,
576i/576p, 720p, 1080i, and 1080p.
• Compatible with all HDMI source devices, PC monitors, plasma HD displays, HDTVs, and audio receivers/amplifiers.
• Supports intelligent color adjustment (discrete RGB color adjustment, hue, saturation, sharpness, contrast, brightness, and preset
color modes).
• Rackmountable: 19-inch ear rackmount.
• Various user interface control, including front-panel push buttons, IR wireless remote control, third-party RS-232 controller (via
simple ASCII), and Ethernet with built-in Web browser.
• Supports IR extender with maximum extend distance reaching 300 meters.
• Supports TV wall function, allowing the image to be divided on multiple displays/monitors.
• Includes 12-VDC power supply, universal-type switch, 100–240 VAC, 50 /60 Hz.

3.1 Remote Control
Before connecting anything to the scaler, observe the following:
• Make sure the voltage supply matches the label on the supplied plug-pack (±10%).
• Make sure the power switch is off.
• Make sure that all system grounds are connected to a common point.
• Avoid powering the device within a system of multiple power sources that are separated by a large distance.
• Connect all audio/video source and display devices.
• Power on all source and display audio-visual devices.
• To yield video /audio to an output, select the input source by using the front panel input buttons, the supplied IR remote control,
or through the RS-232 serial communication port.
• When powering on, the scaler will automatically apply the setting last used.
NOTE: For how to to use the on-screen display (OSD) options, go to Chapter 7, OSD Instructions, in this manual.

Chapter 7: RS-232 Protocol Commands
7.2 Ethernet TCP Setup Guide
The Ethernet (TCP) port allows control of the unit via a computer by redirecting serial commands (COM port) to the unit’s IP
address.
To connect to the unit:
1. Set your PC within the same subnet of the unit (default address 192.168.0.3).
2. Open up a telnet connection to the unit’s IP address with port 5000.
3. Send commands as you would with serial.
To change the network settings of the unit:
1. Set your PC within the same Class C subnet of the unit.
a. For example, if the unit’s default IP address is 192.168.0.3, the PC’s IP address could be 192.168.0.5.
b. Set your PC’s netmask to 255.255.255.0.
2. Run the software included on the CD that came with the unit.
3. Click the search button and select your unit when it is found.
4. Change the unit’s network setting as desired and submit.
To change your computer’s network settings:
1. Set up your computer in the same network of the unit.
2. Go to “Start” and click on “Control Panel.”
3. Double-click on “Network Connections.”
4. Click on “Properties.”
5. Click to select “Internet protocol (TCP/IP)” and click “Properties.”

Chapter 7: RS-232 Protocol Commands
7.3 Data String Format
The data string contains four elements.
[Command] [ ] [Data] [;]
The format is:
1. Command
2. Space
3. Data
4. ;
There is a single space after the command and before the data string. The data string must conclude with a semicolon “;”
(without the quotation marks). All text is full ASCII code and is not case-sensitive. LINK is the same as Link. You can use either
capital letters or lower-case letters and get the same result.
The Link command must be sent first. This establishes a communications link between an external controller (or computer) and
the device you wish to control. When you have an established link, communication via the IR port is disabled. The front panel
remains operational.
The format is:
LINK 01; This will establish the link.
Your commands:
LINK 00; This will terminate the link.
Devices that are firmware version x.x or higher will return a status.
Status is command dependent.
For example: Response: [SKU] [ ] [Status] [;]|
The status is a two-digit numerical code.
Specific details are discussed later in this document.
NOTE: If at any time the AVSC-7DA-HDMI receives an invalid command, a response of “AVSC-7DA-HDMI 01” will be returned.
