Kramer Electronics has launched the PT-571HDCP and PT-572HDCP twisted pair transmitter and receiver for DVI signals. The PT-571HDCP and PT-572HDCP (pictured) can transmit DVI signals directly over a twisted pair cable (shielded twisted pair cables are recommended), and are said to offer an extremely compact and inexpensive solution for DVI signal transmission over long distances.
The PT-571HDCP converts a DVI signal into a signal that can be run over shielded twisted pair cables; the PT-572HDCP receiver then converts the signal back to a DVI signal. Both units feature a bandwidth of up to 1.65Gbps and are HDCP-compliant and HDTV-compatible.
A DVI signal can be transmitted up to 90m at SXGA resolution and up to 30m at UXGA resolution when using Kramer's shielded BC-DGKat524 cable; the company's shielded BC-DGKat623 cable can extend the range for UXGA to 70m, while the forthcoming BC-DGKat7a23 cable will extend the range to 80m for UXGA signals.
The PT-571HDCP and PT-572HDCP use a multi-coloured status LED that illuminates red when receiving power only, orange when an input signal (on the PT-571HDCP) or output signal (on the PT-572HDCP) and power are attached, and yellow when both an active input and output are attached. The PT-571HDCP employs Kramer's Power Connect feature where a single connection to the transmitter powers both units. The required 12V DC is transmitted through the twisted pair cable, along with the other signals, to the receiver.
Housed in the compact Pico TOOLS enclosure, the PT-571HDCP and PT-572HDCP are now available from Kramer Electronics sales companies worldwide.
