The WP-577VH is wall plate transmitter for HDMI and computer graphics video with unbalanced stereo audio and RS-232 signals. The unit encodes the input signals into DGKat twisted pair that it transmits to a compatible DGKat switcher or receiver (for example, the VS-62D or TP-578HDCP). The maximum data transfer rate up to 4.95Gbps (1.65Gbps per graphic channel). The K-Link compatibility uses RS-232 to control other Kramer devices and send data to remote, external RS-232 devices. A single connection to the transmitter or the receiver powers both units. Compatible power connect sources: TP-578H and VS-62D. The automatic live input detection based on video clock presence and automatic switching to the last connected or priority video input. The transmitter has data equalization and reclocking and support protocol 3000.
