KVM Extender
120M & 20KM HDTV KVM Extender
HKF-HKEF-V1.3
The Extender over CAT-5E/6 or fiber uses one piece of CAT-5e/6 or fiber cable to extend the HDTV display up to 120 meters or 20KM for 1920*1080P@60Hz, It not only breaks the limitation of the HDTV cable transmission length, but also CAT-5e/6 or fiber has more flexibility and convenience in cable construction.
It is equipped with HDTV (high definition multimedia interface) connectors and is capable of supporting DVI (digital visual interface) equipment when used with an HDTVto DVI adapter, providing greater flexibility and options when integrating several home theater components.
It offers solutions for residential consumers: HDTV retail and show site, HDTV,STB,DVD and projector factories, space and security concerns, data center control, information distribution, conference room presentation, school and corporate training environments.

The Extender over CAT-5E/6 or fiber uses one piece of CAT-5e/6 or fiber cable to extend the HDTV display up to 120 meters or 20KM for 1920*1080P@60Hz, It not only breaks the limitation of the HDMI cable transmission length, but also CAT-5e/6 or fiber has more flexibility and convenience in cable construction.
It is equipped with HDMI (high definition multimedia interface) connectors and is capable of supporting DVI (digital visual interface) equipment when used with an HDMI to DVI adapter, providing greater flexibility and options when integrating several home theater components.
It offers solutions for residential consumers: HDTV retail and show site, HDTV,STB,DVD and projector factories, space and security concerns, data center control, information distribution, conference room presentation, school and corporate training environments.
2. BENEFITS
1) The length of HDMI cable is fixed and unchangeable after it is produced. Because the HDMI connector can only be soldered or terminated by the professional workers in factory, the users can not reduce or increase by themselves, however CAT-5E/6 or fiber cables are available everywhere and can be processed easily by the user or installer.
2)Because the head of the long HDMI cable is big, using it must in hidden method, what is more, it is not easy to bend the HDMI cable and to pull it through the in-wall tube or tray. However,CAT-5e/6 or fiber cables do not have such problems.
3) With this extender, the transmission distance can be up to 120 meter or 20KM s while using CAT-5e/6 or fiber cables, for the general HDMI cables, they must be customized when the length is over 10 meters.
3. FEATURES
This Extender has many features that enable it to perform in superior manner, among those features and you will find:
1) In order to achieve the high transmission quality please choose the shielded cat-5e or cat-6 or fiber cable.
2) The cables with lower quality will not achieve the perfect transmission effect and long distance.
3) Theoretically the function of the product is normal when adopt short distance transmission.
If the product cannot transmit long distance, that is to say, there are quality problems in the transmission cables
5. Installation steps
Before attempting to use this unit, please check the packaging and make sure the following items are contained in the shipping carton.
1) Main unit no.1 transmitter
2) Main unit no.2 receiver
3) DC5V power supply to power the receiver.
4) One USB A-B cable to transmit the USB data and power the sender.
5) One Ir transmission cable, one Ir receiving cable.
5) User`s manual
