RS232 Gateway with WiFi, UMTS/LTE in IP64 enclosure


This IoT / M2M gateway forwards data from an RS232 interface over a network. Receiving end can be a PC, a mobile device or another gateway device. Suitable networks are local networks, a direct one-to-one connection or data transmission through the internet. Beside a 'live' data connection, a store-and-forward setup can be configured using i.e. FTP server.
