RS232 Gateway with data
logger and LTE / GSM

  • LTE, GSM communication with GNSS
  • USB pendrive data logger
  • Opto-isolated RS232 interface

Gateway dedicated to work with central controlling and monitoring systems. It directly send data from serial interface RS232 via LTE/GSM or Ethernet to the server. Gateway has isolated RS232 interface to communicate with weight scales, energy meters, sensors and any other RS232 devices. It also has an additional data logger function. It uses a USB flash drive for this purpose. In case of communication failure with the server, the gateway keeps a log on a flash drive and sends this data to the server when communication is regained. Can be configured by: internal website, SMS, string from server and configuration file loaded in predefined URL. For accurate time and location it has GPS and RTC.
