Extron has introduced 4K HDMI twisted pair transmitters with input loop-through for DTP Systems.
The DTP T HD2 4K 230 and DTP T HD2 4K 330 are transmitters for sending HDMI with embedded audio, and bidirectional RS-232 and IR signals over a shielded CATx cable to Extron DTP-enabled products.
Both models provide one HDMI input with loop-through to support local monitoring of digital video, and one DTP output. The DTP T HD2 4K 230 extends signals up to 230 feet (70 metres), while the DTP T HD2 4K 330 extends signals up to 330 feet (100 metres).
