Gateway/DCU Solutions
Gateway/DCU Solutions
The GATEWAY / DCU is an intelligent device with built-in RS232, RS485 and RF modules to acquire data from clusters of energy meters or MFMs using inbuilt Modbus / DLMS Software’s. It also equipped with GSM/GPRS module to transmit the data to the remote data acquisition server. DCU is based on an ARM Cortex-A5 processor having 512MB of DDR2 memory and expandable NAND Flash memory up to 2GB. Edge / Sensor data can be stored locally using the onboard SD card option. The cloud interface is LTE with 2G/3G fallback.
