4.0 CONNECTING THE HARDWARE

Referring to the drawings below, connect the proper cables and then connect the AC power adaptor.

Rear Panel Connectors: The rear panel has the connectors required to interface the 1T-VS-668 to the External Inputs, Outputs and Power Supply. The numbers above and below the drawing relate to the connector directly above or below the number. Refer to the corresponding number and functional description below.

1 IR IN: Connect the supplied IR extender to receive the IR signal from the included IR remote. Ensure that the remote is within the direct line-of-sight of the IR extender.

2 SERVICE: Reserved for manufacturer use only.

3 RS-232: Connect to a PC/Laptop or RS-232 control system to use RS-232 commands to control the device (See Section 6.5 for details on RS-232 commands).

4 OUTPUT

a) HDMI 1/2: Connect to an HDMI display or AV Receiver for video and/or audio output.
b) PC/HD: Connect to a monitor/display for video output. For HD (component) output, use the included D-Sub 15pin to 3 RCA adaptor cable for resolutions from 480i-1080p.

NOTE: All three outputs will display the same selected signal at the chosen resolution. When the selected HDMI input source signal has HDCP content the VGA/Component output will not display any image.

c) COAX: Connect to an amplifier or active speakers for audio output in digital format.

NOTE: When the input audio source signal is in bitstream format and the AUDIO SOURCE setting is set to AUTO in the OSD menu, the coaxial output will bypass the input audio signal including compatible surround sound formats.

d) AUDIO: Connect to an amplifier or active speakers for audio output in stereo format.

5 INPUT

a) HDMI 1/2/3: Connect to HDMI sources such as Blu-ray/DVD player for both video and audio signal conversion.
b) PC 1/2/3: Connect to a PC/Laptop source for video signal input with a D-Sub 15pin cable.

c) 3.5mm Mini-jacks: Connect to source's L/R output with 3.5mm mini-jack for audio signal conversion.
NOTE: For HDMI signals you can select in the OSD Menu whether you require audio from the HDMI (AUTO) or from the analog audio input (EXT).
d) YPbPr + L/R: Connect to source equipment such as a DVD player for both video and audio signal conversion.
e) CV + L/R: Connect to a composite video source such as a video/DVD player for both video and audio signal conversion.

6 CONTROL: This port is the link for Telnet or Web GUI controls, connect to an active Ethernet link with an RJ45 terminated cable

7 POWER: Switch this power toggle to turn on and activate the device or turn off to shut it down.

8 DC 5V: Connect the power adaptor included in the package.

Connect the furnished AC Adaptor to the 1T-VS-668. (Use only the furnished adaptor to avoid the possibility of equipment damage due to over-voltage or under-current from generic AC Adapters). Next, connect the appropriate cables to the Input(s) and Output(s) and turn on the destination and source devices.

Plug the AC Adapter into the AC wall outlet flip the rear power switch to the ON position and if necessary press the 'POWER' button on the front of the unit. Verify that the LED above the button lights green which indicates that power has been applied to the 1T-VS-668.

NOTE: To realize maximum quality and performance, use only the highest quality cables with the 1T-VS-668. Low quality cables will cause degradation of the signal quality and limit the distance between both the source and destination devices and the 1T-VS-668.

The 1T-VS-668 can be operated from either the front panel controls or via the included Infrared Remote Control. Since Infrared is the control method used most often by the majority of users, please take the time to familiarize yourself with the location and function of the various control buttons on the Controller.

Front Panel Controls: The front panel has controls to manually control the 1T-VS-668 Universal Presentation Switcher/Scaler.

1 POWER Button and LED: Press this button to switch the device on or to set it to standby mode. Once the device is connected to an active power supply and the Power Switch on the back panel is turned on, the LED will illuminate and the device will switch on automatically.

Notes:
1. Resolution settings 0-13 are RGB encoded. Resolution settings 14-21 are YUV encoded.
2. RS-232 commands will be not executed unless followed with a carriage return (CR) command and for some systems a Line feed (LF) command. Commands are case-insensitive.

5.6 Telnet Control

Before attempting to use the Telnet control, ensure that both the 1T-VS-668 (via the LAN port) and the PC/Laptop or control system being used are connected to the same active network.

You may now start your Telnet client of choice and connect directly to the unit's IP address. If you wish to use the Telnet software that is built into Windows XP, Vista and 7 please follow these instructions:

1. Go to the "Start" menu and click on "Run".

2. After the "Run" command windows opens type "cmd" then press "Enter". This will open the Windows command line interface (CLI).

3. Once in the Windows CLI type "telnet" followed by the IP address of the unit you wish to control. This will connect to the unit and you will see the "Telnet Command Service" prompt.

4. You may now begin sending commands directly to the unit. To receive a listing of all available commands please type “?”.

Notes:

1. The current IP address of the unit can be obtained from the OSD menu under Information.
2. Telnet commands will be not executed unless followed with a carriage return (CR) command and for some systems a Line feed (LF) command. Commands are case-insensitive.

5.7 Web GUI Control

On a PC/Laptop that is connected to same active network as the Scaler, open a web browser and input the unit's IP address on the web address entry bar. The browser will bring up the 1T-VS-668's Web GUI control page (see below for reference). All functions of the unit are controllable from this single screen.

NOTE: The current IP address of the unit can be obtained from the OSD menu under Information.

6.0 TROUBLESHOOTING

If the 1T-VS-668 Scaler does not appear to be functioning, be certain that the source and all other devices connected to the unit are functioning correctly by connecting each device currently connected to the 1T-VS-668's outputs directly to the source using a short length of cable. (In other words, bypass the 1T-VS-668 to insure that the problem is not with the source or destination devices.) If the signal is present under those conditions, make certain that the power is present to the 1T-VS-668. If it is, check all cables for damage. Cables should be undamaged, as short as possible and should be premium quality.

Note: It is strongly recommended that you use premium cables in order to achieve maximum distance cable runs and the best performance possible.

As a final step before contacting technical support, use the IR remote and press the RESET button which will return the unit to the default settings. After trying the above suggestions should the problem still persist, contact your dealer for additional suggestions before contacting tvONE. Should the dealer's technical personnel be unable to assist you, contact tvONE via our support website: http://tvone.crmdesk.com. Create a technical support request on the site and our support team will respond within a short period of time.
