SPI LED pixel transmitter/receiver system up to 50m kit 5 Tx 5 Rx - Contest SMART-TxRx

The Contest SMART-TxRx system extends the reach of SPI-based pixel LED systems, increasing the maximum distance from less than 5 m to up to 50 m for each transmitter/receiver pair. The transmitter automatically changes the SPI (TTL) signal into a stable balanced signal for long runs, reducing interference and preventing data loss; at the destination, the receiver converts it back to SPI (TTL). Operation is fully automatic with a 5 - 24 V DC supply.

The kit contains 5 transmitters and 5 receivers, allowing several installations to be managed or a single line to be extended through multiple cascaded stages. Its extremely compact 31 mm design and large solder points make integration straightforward in suspended ceilings and restricted spaces. The system also permits the controller to be positioned remotely, removing aesthetic or logistical constraints.

SMART-TxRx is intended for architectural lighting, retail, hospitality and complex projects with long pixel LED runs where the typical 5 m limit of the SPI signal or protocol must be exceeded. The transmitter has 3 solder tracks for its input and 2 for its output; the receiver uses 2 input tracks and 3 output tracks. Tx input is SPI (TTL), Tx output is balanced, while the receiver accepts a balanced signal and provides SPI (TTL). Permitted ambient temperature is -20 to +55 °C, the IP rating is 20, dimensions are 31 x 10 x 5 mm and weight is 2 g.
