Slot-card for the modular HDBT matrixes: HDBT IN, IR IN, RS232, HDMI OUT - Enables ‘remote sources’ connection to the matrix up to 70m/230ft away using an HDBaseT transmitter, with received signals then routed by the matrix as with any local source. Control of source device cannot be routed internally through the matrix - an IR loop port is included on the card for corresponding IR TX port connection using the WyreStorm IR Link cable (CAB-IR-LINK). Similarly, for RS232 control a phoenix port breaks-out or injects serial commands to be sent down the HDBaseT link.
