Gateway processes data from temperature sensors or access chips with 1-WIRE (DALLAS) communication on its two data buses. Each bus with 1-WIRE communication can serve up to 20 temperature sensors with data about humidity (totally 40 elements) and sends their values including error states through the interface RS 485 and RS 232 with Modbus RTU protocol. The gateway is configurated via 1-WIRE-GWY-TOOL application through USB cable which makes the administration of sensors position and all the necessary settings easy. Signal LEDs on front panel indicate device power supply, communication on RS 485, RS 232 and presence of temperature sensor for each bus separately.

In cooperation with the company TECO a.s. a variant of the converter for the CIB bus with the designation C-1W-4000M (order. no. TXN 133 92) was developed for the TECOMAT control system.
