Kramer TP-581T Description

The Kramer TP-581T is a high performance, extended-reach HDBaseT transmitter for 1080p60Hz HDMI, Ethernet, RS-232 and IR signals over twisted pair. The Kramer TP-581T converts all input signals into the transmitted HDBaseT signal. It extends video signals to up to 130m (430ft) over CAT copper cables at up to 1080p@60Hz 36bpp video resolution. The Kramer TP-582R converts the HDBaseT twisted pair signal back to Ethernet, RS-232, IR and two HDMI outputs, and de-embeds the audio to S/PDIF and TOSLINK® audio outputs. See also: Kramer TP-582R.
