MT Series Transcoder

Innovative Transcoder Enables Bi-Directional Remote Control - Available at Digi-Key

Linx Technologies' revolutionary MT Series transcoder IC provides unprecedented features for bi-directional remote control and command applications. In the past, encoder and decoder ICs were commonly used to allow the status of inputs such as switch or button closures to be sent in one direction across a wireless link. While the MT can perform these basic uni-directional functions with ease, it also allows the bi-directional exchange of information and reception confirmation across an external wireless link such as a Linx transceiver module. When combined with external feedback, the transcoder can also verify that specified actions have actually taken place.

Overview

There are many applications for the bi-directional exchange of information available in these ICs. For example, a remote valve might confirm it has fully closed, a nurse call system could indicate "help is on the way", or an automobile security system would confirm it had armed and in the event of a break-in alert the owner via their system’s keyfob. The MT is even capable of sending variable data such as time, temperature, pressure, or text along with control information.

The transcoder provides eight lines that can be configured as inputs or outputs and individually set for latched or momentary operation. Recognition of the individual outputs can be easily defined for each device by the manufacturer or end user. This allows the creation of user groups, relationships, and permissions. A large twenty-four bit address size makes transmissions highly unique, minimizing the possibility of conflict between multiple devices. An automatic confirmation indicates that the transmission was successfully received. The MT also outputs the ID of the originating transcoder for logging or identification.

In addition to these powerful features, a Serial Interface Engine (SIE) allows the transcoder to be configured and controlled from an external microcontroller or PC. Permissions and users can be configured, modes and functions set and external data added to the transmission stream. A targeting feature allows commands to be directed to specific devices. The MT is housed in a tiny 20-pin SSOP package and features low supply voltage, current consumption, and selectable baud rates. Its basic feature set is also compatible with Linx MS Series encoder and decoder ICs.
