Ethernet extension

The Ethernet connection port has four ports with the transmitter. Any one of the four ports is connected to the Ethernet. The other ports are connected to the computer to set up the LAN.

HDBaseT transmission standard

Support HDBaseT transmission standard, support PoC function, with long-distance transmission, high transmission rate and cable economy advantage over HDMI.

HD video transmission capability

Support full HD video/ultra HD signal: 1080p@60Hz@48b/pixels, 1080P 3D and 4Kx2K resolution.

Long-distance transmission capability

Thanks to the HDBaseT transmission standard, the maximum distance of a single CAT5e cable with a 1080P HDBT signal is 90m, and the single CAT5e/6a/7 cable has a maximum distance of 60m for 4K×2K.

Powerful compatibility

Compatible with HDTV, HDCP1.2 and HDMI1.4 compliant, compatible with 3D video signals, HDMI signals support resolution 1080P (HD) / 1080i / 720P / 576P / 576i /480P/480i, high quality dark field video signal 24/30/36 bit deep color.

Diverse and flexible control methods

Support RS232 control protocol, two-way infrared transmission and acceptance.


Reliable, long-distance transmission of HDMI video and bidirectional control signals over a single twisted pair cable. Taking full advantage of the advantages of twisted pair, while ensuring the best signal quality, provides users with an economical solution.


The DDC communication between EDID and HDCP between the signal source and the display device can be continuously maintained for reliable operation while ensuring direct compatibility between devices and optimal signal transmission.


Support remote power supply, can supply power to any one of the transmitter or receiver, and the other device does not need external power supply, and supplies power through twisted pair cable, which allows two devices to share an external power supply, which increases product flexibility. Sex. Supporting the CEC function, when the connected HDMI source device and the terminal display device support the CEC function, the CEC signal allows the user to control all devices connected to the HDMI interface, and becomes a single remote control device that controls all HDMI connections. For example, if the user puts the DVD into the Blu-ray player, the TV will automatically turn on due to the notification of the CEC signal, and then the video channel will automatically switch to the channel connected to the player. When the user turns off the TV, the CEC signal also informs the HDMI connected device to enter standby.
