Product Description

- The collector DC200 installed between DCU and water/electric meters.

- The collector DC200 links with DCU platform through PLC network. While it communicates with electricity meters through local RS485 technology and water meter via RF LoRa technology.

- The DCU serves as the main node in the PLC network, and DC200 are sub nodes. Main node is responsible for managing the network, including sub node registration, network path optimization, etc.

- Sub nodes receive commands from main node and make response to main node through power line network.

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.
