Kramer Rolls Out HDMI-to-Coax Devices

Kramer Electronics has introduced the 640T HDMI-Coax Transmitter and the 640R Coax-HDMI Receiver. The units are the latest additions to the company's TOOLS line of compact solution products, according to Kramer officials.

640T HDMI-Coax Transmitter

The 640T and 640R were designed for boardroom and projection applications, as well as long-range multimedia extensions for schools, hospitals, security, and retail applications. Because many installations have existing RGBHV cable infrastructures already in place, the 640T and 640R allow existing cabling to be used to send HDCP-compliant HDMI signals over long distances.

Both units feature plug-and-play installation with no adjustments, the company says. They support HDMI 1.3 up to 10.2 Gbps and are useful for upgrading analog installations to digital, extending signal distribution up to 500 feet depending on signal resolution and the gauge of the wire used in the cabling.

The 640T transmitter takes an HDMI signal, codes it, and transmits red, green, blue, and clock signals over coaxial cables to the 640R receiver. The transmitter features digital signal transmission without compression or conversion and has a single HDMI input, five BNC connectors, and a bandwidth of up to 3.4 Gbps per graphic channel. It can also transmit power and IR signals.

640R Coax-HDMI Receiver

Both the 640T's and 640R's power and infrared signals are bidirectional. Through the use of optional IR emitters or sensors, IR signals can be transmitted in either direction from the source to control the display or from the display to control products at the source location, the company says. For power, only one of the two units needs to be powered, as the power travels in either direction from the unit that is powered to the unit that is not.

The 640R receiver accepts the coded coaxial signal transmitted by the transmitter, decodes the red, green, blue, and clock components, and converts them to HDMI output. The receiver features five BNC input connectors and one HDMI output, as well as an IR input and output on a 3.5 mm mini jack. The 640R also supports up to 1.65 Gbps bandwidth per graphic channel.

The 640T HDMI-Coax Transmitter and 640R Coax-HDMI Receiver are available with a list price of $450 each.
