Depending on configuration, the DS104 can operate as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Occupancy \/ sensor decoder<\/li>\n\n\n\n<li>Relay \/ switch decoder<\/li>\n\n\n\n<li>Servo decoder<\/li>\n\n\n\n<li>LED \/ signal decoder<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It may be one of the few systems \u2014 if not the only system \u2014 capable of combining all these functions within a single device.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Origin &amp; Philosophy<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The modelrailelectronics.com developments originated within a young model railroad club that wanted to build an H0 layout for both 2-rail and 3-rail users, starting with a very limited budget and few members.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Initially, existing DIY products were tested, but based on their experiences, the club decided to design its own products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because these designs are DIY-based and the development has no profit motive, the resulting products are very affordable compared to commercially available alternatives.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Modular I2C Expansion<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The DS104 features two I2C connectors, allowing any combination of compatible modules to be connected:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DS201 current detection module<\/li>\n\n\n\n<li>DS202 mass detection module<\/li>\n\n\n\n<li>DS203 relay module<\/li>\n\n\n\n<li>DS204 sensor module (in development)<\/li>\n\n\n\n<li>DS205 reverse loop module (in development)<\/li>\n\n\n\n<li>DS206 switch module (in development)<\/li>\n\n\n\n<li>PCA9685 PWM module<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When using the PCA9685 module, both servos and LEDs\/signals can be controlled. The DS104 supports standard switch commands for signals as well as more efficient aspect commands, helping reduce the number of LocoNet addresses required per signal (depending on your model railroad software and command station combination).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your command station does not support a LocoNet bus, you can add connectivity to your computer using our <strong><a href=\"\/products\/ds101\">DS101 Lnet USB Interface &amp; Monitor<\/a><\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">DS-Configurator App<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Configuration of the DS104 Lnet I2C interface is handled via our DS-Configurator v1.02 app, available for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Windows<\/li>\n\n\n\n<li>Linux<\/li>\n\n\n\n<li>macOS<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The application is multilingual by default and can be set to: English, Dutch, German, French, Spanish, or Italian.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We are currently preparing a user manual for DS-Configurator and welcome reviewers \u2014 especially for translation verifications.<br>Meanwhile you can read more about DS-Configurator on the <a href=\"\/products\/ds-configurator\">DS-Configurator<\/a> page.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">DIY concept<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">All DS projects are supplied as standard DIY kits, including the printed circuit board and all required components. With the proper tools (see the \u201c<a href=\"\/how-to\" data-type=\"page\" data-id=\"984\">How To<\/a>\u201d page) and a bit of practice, these kits can be assembled even by less experienced hobbyists.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you prefer not to build the kit yourself, fully assembled and tested units are available upon request.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Testing &amp; feedback<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Although we continuously test our products, additional real-world feedback is always welcome to further validate the correct functioning of the DS104 sketch and supporting applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are interested in participating in testing or reviewing, please contact us to discuss the possibilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>LocoNet\u00ae is a registered trademark of Digitrax, Inc.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We are proud to announce the release of the DS104 v0.89 sketch, together with the DS-Configurator v1.02 app. The DS104 Lnet I2C Interface is a versatile LocoNet-compatible I2C interface designed to offer maximum flexibility for model railroad applications.
