sindcon RS485 Modbus LoRaWAN Bridge User Manual
Product Overview
Sindcon’s Neptune series Modbus-LoRaWAN bridge is an affordable solution for converting traditional wired Modbus devices into Lo RaWAN wireless nodes. It enables reading and writing of any register of the connected Modbus device through the Lo RaWAN. The configuration of Modbus register mapping of the Modbus-LoRaWAN bridge device can be easily done remotely from the Sindcon LoRaWAN server by downlink commands. Moreover, users can use the Mobile App (Busy Box) which are available from Apple Store and Google Store, to configure the device to different Modbus devices on field.

Install the RS485_LoRa Bridge Model NPL-IN(AC) on the Energy Meter and connect the cables, follow the steps below:
Step 1: Connect to Energy Meter (Modbus Port):
- Locate the RS485_LoRa Bridge Model NPL-IN(AC).
- Identify the upper port on the RS485_LoRa Bridge, labeled as “Modbus Port” (AB).
- Connect one end of a suitable RS485 cable to the Modbus Port (AB) of the RS485_LoRa Bridge.
- Connect the other end of the RS485 cable to the corresponding Modbus communication port on the Energy Meter.
Step 2: Power Supply Connection:
- Find the lower port on the R5485_LoRa Bridge, labeled as “Power Supply Port.”
- Connect the power supply source. Port on the RS485_LoRa Bridge. Ensure that the voltage and current rating of the power supply match the requirements of the RS485_LoRa Bridge.
Step 3: Install the Antenna,
- Locate the antenna port on the RS485_LoRa Bridge, situated on top.
- Connect the provided antenna to the Antenna Port securely. The antenna is crucial for establishing wireless communication between the RS485_LoRa Bridge and other LoRa devices.
Step 4: Check Connections and Power Up:
- Double-check all the connections to make sure they are correctly installed according to the connection definitions.
- Ensure that the RS485 cable is securely connected to both the RS485_LoRa Bridge and the Energy Meter.
- Confirm that the power supply is correctly connected to the Power Supply Port.
- Verify that the antenna is securely attached to the Antenna Port.
- Once everything is in place, power on the RS485_LoRa Bridge by turning on the connected power supply.
