The SEPO to RS485 gateway is a device for surface mounting. It serves as bidirectional gateway between the SEPO devices and Datos BM-CH controllers. The gateway receives telegrams from all SEPO devices and puts them on the RS485-Bus or enables the RS485-system to transmit RF-telegramms to SEPO devices. There is no special additional software needed. The gateway comes with the Datos BM-CH-SEPO driver.
