Waterproof Stardard 485Port LoRaWAN Universal Collector for
DCRL12-RDK150 G2AY collector (V2.03) (DTU) (uplink LoRaWAN,
downlink RS485) is a universal protocol product what based on edge
computing on the directional protocol collector. The collector is
suitable for all communication protocols of the RS485 interface
The collector is simple and convenient to use, and only needs to
install the collector in the area where covered by the LoRaWAN
signal, complete point-to-point data collection through the LoRaWAN
gateway, low power consumption, long life, two-way data
transmission, and provide the reliable guarantee for accurate
collection of real-time data; The collector only needs to
successfully set the active upload period and the upload task list,
and then automatically uploads the response data received by the
collector to the gateway, and the gateway automatically uploads the
data to the management platform.
The management of the collector by the platform is based on the
node information of the collector's LoRaWAN module, and the node
information is unique. The collector is designed in accordance with
the concept of industrial control standards, energy saving,
completely isolated, and communication security isolation! It has
the characteristics of strong anti-interference ability, long
transmission distance, high speed and stable operation. More
importantly, it has high adaptable. There is no requirement for the
communication protocol of the downlink terminal equipment. Only the
baud rate of the RS485 bus is required to realize automatic
acquisition of many kinds or multiple terminal devices.

1. The collector applies edge computing technology and has strong
data storage, processing and control capabilities.
2. We can set the collector's upload task list and the upload
period to realize automatic reading and active uploading through
the local configuration RS485 port and the remote LoRaWAN port.
3. Professional interface data control technology, which
preferentially processes the terminal transparent transmission
instruction frame and the collector parameter setting instruction
frame issued by the the gateway to realize direct control of the
terminal by the master station.
4. Automatically detect and process the data stream of the LoRaWAN
port, effectively dividing the data, realize the function of
receiving/transmitting big data; Overcome the limitation of LoRaWAN
single frame data volume less than 46 bytes.
5. The PC end of setting parameters software can read/write
multiple operating parameters of the collector through the local
RS485 interface, and the reading task of the terminal device only
have downloads function. The multi-layer management of the terminal
device by the collector is omitted, which simplifies the workload
and operation difficulty of the field parameter configuration.
6. There are many status indicators of the collector. The status
indicator can be used to determine the working status of the
7. Communication isolation, effective high voltage isolation of
digital signals. The isolation device adopts high-reliability
dual-channel digital isolation chip, which has high electromagnetic
immunity and low radiation characteristics, ensuring complete
isolation of communication, strong anti-interference ability and
long communication distance;
8. The parameters configured when the module is powered off can be
saved and automatically restored when the power is restored.
9. Using 2P rail type installation, small size, good stability.
10. Waterproof protection.
