Kramer TP-574 HDMI, Bidirectional RS−232 & IR over Twisted Pair Receiver
The Kramer TP−574 is a DGKat™ twisted pair receiver for HDMI, bidirectional RS−232 and infrared signals. The Kramer TP−573 converts the input signals to a twisted pair signal and the Kramer TP−574 converts it back to HDMI, RS−232 and infrared signals.
