1.0 INTRODUCTION 
 

Thanks for purchasing the 1T-CT-680 Series HDMI Over Multiple Coax Extender 
product from TV One. The individual components of this HDMI Over 5-Coax Extender 
system consist of the 1T-CT-681 Transmitter and the 1T-CT-682 Receiver which 
constitutes a system used to transmit deep color (12 bits), V1.3 HDMI or DVI-D signals 
(with appropriate DVI to HDMI Cable Adapter) at resolutions up to 1920x1200 and 
1080p, plus transmission of embedded, lossless audio, over RG-6 type coaxial cables 
or RGBHV cable with 5BNC. The 1T-CT-680 series extender can achieve signal 
distribution distances of up to 100 meters (325 feet) for 1080p/8 bit signals and 75 
meters (245 feet) for 1080p/12 bit signals. Four or five

 

RG-6 type coaxial cables are 

required. One cable is required for each of the video components (R-G-B) and one for a 
clock signal. Under some conditions involving relatively short cable runs, the DC voltage 
from the transmitter can be sent to the receiver unit on a fifth coaxial cable negating the 
need for a separate power supply for the receiver. Both the Transmitter and Receiver 
units feature the unique TV One-task locking power connectors to enhance overall 
system mechanical security.
