DL-HD70 Summary

The DigitaLinx DL-HD70 extender set transmits HDMI (1080p, 4Kx2K (UHD) & 3D) including HDCP 2.2, bidirectional IR, and RS232 up to 70 meters away using a single 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. All accessories are included including two IR emitters, two IR receivers, and two pairs of mounting brackets with screws. The individual transmitter and receiver are not compatible with other HDBaseT devices due to proprietary PoE circuitry.
