Product Description
- The WFET-DC800 is an intelligent gateway based on embedded Linux for Smart Grid applications. The basic function of WFET-DC800 is scheduled meter readings via its concentrator functionality, as well as direct end-to-end secure gateway function between the Head-end system (HES) and meters. This optimized use of communication media saves cost while maintaining full flexibility.
- WFET-DC800 communicates with connected meter via G3-PLC/RS485 and transfers data to HES through GPRS modem or Ethernet. It is designed using DLMS/COSEM standard to guarantee interoperability.

Features
1. LED Indication
DC200 is composed of five LED lights:
POWER: Power on indication, always on
RUN: Running indication, the frequency of blink is 2.5Hz
UP_TX: blink when send data to uplink network
UP_RX: blink when receive data from uplink network
DN_TX/RX: blink when send /receive data from downlink network
(Note: Uplink: G3-PLC/BPLC/Wi-SUN RF Mesh/G3, WIFI; Downlink: RS485 / RF-P2P connect to electricity meter, LoRa connect to water meter)
2. RS485 Communication interface
It is suggested that the voltage between RS485 A and RS485 B should be measured every time a meter is installed. It should not be zero or negative. RS485 line length should not be exceed 1000m.
3. LoRa Communication interface
DC200 has two frequency of LoRa, one is fixed for wake up the water meter, the other one is unfixed for data notification and reading meter data.
4. RF P2P Communication interface
DC200 support the point to point RF star network downlink communication.
5. WiFi Communication interface
There is one WiFi function for debug and setting/reading its parameters via AT commands, including electricity/water meter archive.
