The DigitaLinx DL-HD70 HDBaseT extender set transmits HDMI, bidirectional IR, and
RS232 up to 70 meters away using a single Category 6 twisted pair cable.

Built-in surge protection and diagnostic LEDs ensure hassle-free and robust installations.
Flexible power design allows the units to be powered at either the TX or RX end, and
only one power supply is required. The 12 volt power supply is secured with a screw-on
connector to prevent the power from being accidentally disconnected.

The DL-HD70 is sold only as a set. The individual transmitter and receiver are not
compatible with other HDBaseT devices due to proprietary PoE circuitry.
