DIGITAL MODULATOR
1. GENERAL
1.1 Description
The HD4660 module able to generate a signal in DVB-T format (Digital Terrestrial
Television) from HDMI and YPbPr (RCA) and CVBS(RCA) input.
HD4660 is MPEG-4 and MPEG-2 encoding, DVB-T modulation integrated device to
convert HDMI and YPbPr (RCA) and CVBS(RCA) signal to DVB-T RF out.
The HD4660 module adjusts the compression rate to the available bandwidth, using
the modulation DVB-T parameters.

2. INSTALLATION
2.1 What’s in the Box
One HD4660 Encoder / Modulator
One power cable
2.2 Connection
The HD4660 unit comes standard with HDMI, Component, and Composite video inputs.
Component Connection: Connect the Y (Green), Pb (Blue), and Pr (Red) video source cable
to the unit’s Component input ports. If using a Composite Video source, use a 75Ω coaxial
cable with RCA connectors to connect the video source to the unit’s CVBS port.
Use RCA cables to connect the audio source to the red / white AUDIO L and AUDIO R
INPUT jacks.
Use a quality 75Ω coaxial cable with “F” connectors from the unit’s RF OUT jack to the
distribution system or directly to a television.
Connect the power cord to an appropriately rated AC power outlet.
Once connected to power, the device turns on and it takes about 20 seconds to be
operational. Then the message “Initial Please wait” appears on the display. After 60 seconds
the message “Status (Enter) & IP Address 192.*.*.*” on the display.
2.2.1 DEVICE Programming and Setup
Connect an Ethernet cable directly (no Cross Over cable required) to the Ethernet Port
on the rear panel of the encoder and then connect the Ethernet cable to an Ethernet switch
or connect an Ethernet Cable to your PC.
