Modbus RTU
The Modus RTU module was designed for use in elevator control systems. The module supported 2 x 1A open collector outputs and 2 x optically isolated inputs. Upto 61 modules could connect together with selectable device addresses set by DIP switch. The design used standard CAT5e patch cables to link together. LED indicators are to show power and active data. The source code written in ANSI C runs in an AT Mega 8 microcontroller and power is provided from a switching buck regulator allowing an input voltage between 5 – 40V DC.
