RAK2470 WisNode Bridge Serial Prime Datasheet
Overview
Description
The RAK2470 WisNode Bridge Serial Prime is an RS485 to LoRaWAN converter designed for outdoor industrial applications. Utilizing the LoRaWAN network, RAK2470 wirelessly transmits RS485 data to and from end devices.
Additionally, RAK2470 WisNode Bridge Serial Prime comes with a T-type conversion cable, enabling it to link up with any RS485 equipped sensors. Both the RAK2470 and connected sensors can be powered via the DC power port.
RAK2470's default interface, the M12-4 circular connector, permits direct connection to MPPT Solar Charge Controllers, Inverters, or Inverter Integrated Machines.
Together with a RAK WisGate Gateway and LoRa Server products, RAK2470 can quickly and easily build a wireless industrial field control system. It is designed with industrial-grade protection, accommodates a wide range of voltage supplies, supports pole mounting, and facilitates field installation and use.

Hardware
The hardware specification describes the device's interfaces and parameters.
Interfaces
The RAK2470 WisNode Bridge Serial Prime comes with an M12-4 circular connector (including power and RS485 data interfaces).
The power interface needs to be powered by a DC power supply (5 ~ 12 V), and the voltage must be stable.
In addition, the RS485 host baud rate supports 9600 and 115200, and up to 32 devices can be connected.
| Pin | Circular Connector | Description | Type |
|---|---|---|---|
| 1 | VCC | Power input (5 ~ 12 VDC) | PI (Power input) |
| 2 | RS485_A | RS485 A+ | IO (Bidirectional) |
| 3 | RS485_B | RS485 B- | IO (Bidirectional) |
| 4 | GND | Ground | PI (Power input) |
T-Type Conversion Cable
The RAK2470 comes with a 1 m T-type conversion cable for each branch. Using this conversion cable, the RAK2470 can be connected to any RS485 equipped sensors, and power can be supplied to both the RAK2470 and the connected sensor via the DC power port.
The standard length of the T-type conversion cable is 1 m. If you need to customize the cable length, kindly contact inquiry@rakwireless.com.
