The TP-581T is a high-quality twisted pair transmitter for HDMI, Ethernet 100BaseT, bidirectional RS-232 and IR signals. The TP-581T takes the HDMI input, and converts it with the Ethernet 100BaseT, RS-232 and IR input signals to a twisted pair signal. The TP-582R converts the twisted pair signal back to Ethernet 100BaseT, RS-232, IR and two HDMI outputs, and de-embeds the audio to S/PDIF and TOSLINK audio outputs.
