The gateway processes data from temperature sensors or iButton keys through 1-Wire (DALLAS) interface built into the gateway's two data buses. Each bus can support up to 20 temperature or humidity sensors, allowing the gateway to serve up to 40 devices at once and to read their state values through RS485 and RS432 buses using the Modbus RTU protocol. 

For configuration, the 1-Wire-GWY-Tool application is used, allowing the user to easily manage sensor configuration, sensor position, and other necessary settings through the standard USB interface. The gateway also features a set of LED diodes for power indication, RS485/RS232 communication indication, and temperature sensor presence indication with each bus indicated separately.
