JetWave 4110L Quick Start Guide 2
Reading the built-in Modbus Registers on JW 4110L Wirelessly
Introduction
The JetWave4110L is an outdoor industrial grade LoRa Gateway for the Serial to LoRa environment monitoring market. The Gateway series equips with one embedded LoRa module, one M12 connecter, 1 serial port and 1 AI/DI, and 1DO.
In Quickstart Guide 1, we have already managed to set up the communication between 2 JetWave 4110L, in this example, we will explore more on the Modbus Slave function built into the JetWave
Objectives of this quick start guide
- Setting up the Modbus function on the JetWave 4110L
- Reading the values from Modbus registers on the JetWave 4110L
- Making sense of the values
- Simple troubleshooting techniques
Overview
In part 1 we have successfully created a working data stream between a pair
for JetWave 4110L, now we will explore the Modbus Slave and functionalities
built into the JetWave 4110L.
The JetWave 4110L has the following interfaces built for you to use as with
Modbus slave:
- Digital / Analogue input
o Using the same input pin, you will have to select the mode using the
JetControl SW during setup.
o Modes:
- Normal ADC (mV)
- Logic High/Low
- 4~20mA (%)
- 0~10V (%)
- 4~20mA (mA)
- 0~20mA (%)
- 0~20mA (mA)
- Digital Output
o Latch mode
- Open Drain
- JetWave 4110L has internal pull up resistors in this mode
o PWM mode
- Allows you to control output voltage level using PWM
- Max = Voltage input on the JetWave 4110L
Setting up the JetWave 4110L for basic wireless communication

With the same basic configuration as part one, we will just connect unit A to
PC / or any kind of Modbus master and then have it read the data from the
Modbus Addresses of Unit B.
Connecting to the device using JetControl Software and configuration

| Unit A Device Settings
• Sames settings from Part 1, do not need to change.
Unit B Device Settings
• Sames settings from Part 1
• However you need to set the Digital Output / Input type
How to set up the Digital Output / Input type using the JetControl S/W
• Keep the same settings on both Device and RF settings as part 1
• Head to I/O Pin Tab
• Under Input Pin Select what you require
• Write to device|
Putting your solution together
Reading the digital input values
Information is taken from the user manual
To read the values from the Digital Input, the register to read is 0x3000
(Hexadecimal value) which converts to 12288 in decimal. Depending on the
Modbus master you are using it may start with 0 or 1, so the address might be
0x3000 or 0x3001 depending on the settings of the Modbus Master.
The software that I am using requires to use 0x3001 / 0d12288 instead.
Example 1: 0~10V / normal ADC (mV)
In this example, the device has already been set up to by DI Type 0: 0~10V / normal ADC (mV)
As shown in the register will return a value from 0 – 5000 (0 – 10000mV) which
means each step of the registers = 2mV
CAS Modbus Scanner and with my voltage set to about 4V on my power supply:c
We were able to read 2221 from the register, using the formulae of DI_Value2: 2221 2 = 4442mV
CAS Modbus Scanner and with my voltage set to about 8V on my power supply:
We were able to read 4229 from the register, using the formulae of DI_Value2: 4229 2 = 8458mV
Troubleshooting Tips
- The status light is constantly blinking red
- Check the RS-485 connecting to make sure it has a solid connection or swap the Tx/Rx pair if have to
- Text transmitted over terminal is not readable gibberish
- Check the Com Port Settings both on the Device and the Terminal Software to make sure they match, both devices should have matching settings as well.
