The SMART-TxRx definitively solves this equation by symmetrizing the signal to reach 50 meters between each transmitter\/receiver pair. By daisy-chaining several kits, no distance remains unreachable, allowing installations to be designed without compromising on layout.  <\/p>\n<p><strong>Automatic symmetrization and freedom of layout.<\/strong><\/p>\n<p>The system works in pairs: the transmitter (Tx) picks up the SPI signal (TTL) from the controller or a previous ribbon, automatically converts it into a balanced signal capable of traversing 50 meters of cable without degradation, then the receiver (Rx) converts it back into its own SPI signal to power the rest of the installation. This symmetrization eliminates electromagnetic interference and preserves the integrity of the signal pixel by pixel, guaranteeing smooth animation even over very long distances. No adjustment is required: conversion takes place automatically on power-up (5-24 V DC).   In addition to ribbon-to ribbon extension, the SMART-TxRx allows the controller to be physically remote from the lighting installation. No need to install the control console in the immediate vicinity of the ribbons: place it in an equipment room, false ceiling or any other convenient location, and the transmitter will send the signal 50 meters to the first receiver, which will transmit the data to the rest of the installation. This flexibility drastically simplifies complex projects where access to the ribbons is difficult or aesthetics dictate masking the control electronics.  <\/p>\n<p><strong>Compact design and professional kit.<\/strong><\/p>\n<p>At just 31 \u00d7 10 \u00d7 5 mm and weighing just 2 grams, each module is easily concealed in aluminum profiles, behind cornices or within luminaires. Large soldering points make connection easy, even for technicians with little experience of micro-soldering. Three tracks on the SPI side (data, power, ground), two tracks on the symmetrical side: installation remains intuitive despite the technical nature of the system. The extended temperature range (-20\u00b0C to +55\u00b0C) enables use in demanding environments, from the cold of refrigerated display cases to the heat of certain technical areas.    Packaged in a kit of 5 transmitters and 5 receivers, it meets the needs of installers managing several sites or a single installation requiring several extensions. Each pair remains independent, allowing modules to be distributed according to the topology of your project: a large linear installation with several symmetrical stages, or five separate installations each benefiting from a 50-meter extension. This versatility makes it an indispensable tool for any SMART range requiring an extension beyond the 5-meter limit.  <\/p>\n<p><strong>Technical specifications :<\/strong><\/p>\n<ul>\n<li>Input voltage: 5~24 V DC<\/li>\n<li>Input signal: Tx: SPI (TTL) \/ Rx: Balanced signal<\/li>\n<li>Output signal: Tx: Balanced signal \/ Rx: SPI (TTL)<\/li>\n<li>Input connection (Tx): 3 solder tracks<\/li>\n<li>Output connection (Tx): 2 solder tracks<\/li>\n<li>Input connection (Rx): 2 solder tracks<\/li>\n<li>Output connection (Rx): 3 solder tracks<\/li>\n<li>Kit of 5 Tx \/ 5 Rx<\/li>\n<li>Operating environment\n<ul>\n<li>Ambient temperature: -20 \u00b0C to +55 \u00b0C<\/li>\n<li>IP rating: 20<\/li>\n<\/ul>\n<\/li>\n<li>Physical characteristics\n<ul>\n<li>Dimensions: 31 x 10 x 5 mm<\/li>\n<li>Weight: 2 g<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The SMART-TxRx kit pushes back the distance limits of SMART pixel LED installations.
