MT Series Remote Control Transcoder

Bi-Directional Remote Control Transcoder

MT Series transcoders are designed for bi-directional remote control applications. Eight status lines can be set up in any combination of inputs and outputs for the transfer of button or contact states. An automatic acknowledgement indicates that the transmission was successfully received. The large, twenty-four bit address size makes transmissions highly unique, minimizing the possibility of conflict between multiple devices. A Serial Interface Engine (SIE) allows configuration and control of the transcoder by an external microprocessor or PC. When activated, the transcoder encodes the current input states and its address into a packet and outputs a digital data stream. This data can be sent to a receiving unit by RF modules, infrared link or even a wire. The receiving unit checks the received packet to make sure there are no errors and that the received address has been learned. If everything is good, then the transcoder replicates the received input states on its outputs. These outputs are connected to whatever circuitry is required by the application. The receiving unit then sends an acknowledgement to indicate that the command was successfully received.
