3. Specification
4. Applications

Step 1: Antenna settings for both master and slave
Step 2: 12-24VDC power supply for both slave and master via M12 connector
Step 3: Bring the antenna of Wireless bridge Slave closer to the antenna of Wireless bridge Master. If:
Buzzer plays 1 peep sound, LED blink 1 time, that means registering Slave on Master successfully.
Buzzer plays 2 peep sounds, LED blink 2 times, that this Wireless bridge Slave is already registered.
5. Operation Principle
5.1 Add RS485 Wireless Bridge Slave into RS485
Wireless Bridge Master
NOTE: Use your hand to tighten the antenna on the sensor, not using tools.
If you do not hear the "Peep" sound, please disconnect the power the Wireless bridge Slave, wait a
few minute and try again.

Step 4: When you hear a beep indicating the successful registration of Slave to Master, you are ready to use the
product.
Press and hold the push button or bring the magnet near the Hall sensor:
For 2s => see the LED blink once or the buzzer will ring 1 Beep => Release the push button or Take the
magnet out to set RF data rate RF 50 kbps
For 5s => see the LED blink twice or the buzzer beep 2 Beep => release the push button or take the magnet
out to set RF data rate RF 625 bps
For 10s => see the LED blinking 3 times or the buzzer buzzes 3 Beep => release the push button or take the
magnet to perform the User factory reset (User factory reset = reset frequency, RF transmit power, data rate,
Slave ID, Modbus operating parameters, compare time for data status).
If it takes more than 30 seconds, the button will be deactivated.
WS433-BL replaces the traditional RS485 transmission line and wireless data transmission together. So after
adding, the connection will be normal as traditional RS485 connection.
- WS433-BL Slave connects to the ModbusRTU device below (power meter, level meter,...);
- WS433-BL Master connects to the control device (PLC, IoT Gateway,..).
5.2 Hall sensor and button function
The Wireless Bridges are pre-configured, only use this feature when you really want to change the
data rate.
Hall buttons and sensors (using magnets for activation) have the same function and are only
available for the first 5 minutes after power on

Default configuration:
Frequency: 433.92 MHz
RF transmit power: 15 dBm
RF data rate: 50 kbps
For example: when we read WS433-BL Slave data from WS433-BL Master, the LED on the Slave will change.
5.3 LED of WS433-BL
LED of WS433-BL will change state when RF data is received.

First, you need to prepare
5.4 Checking connection with Modbus Tool
Default offline address:
The Wireless Bridge Master address is 200;
The Wireless Bridge Slave address is 201;
Other Modbus RTU devices have the address provided by the manufacturer.

Step 1: Connect Antenna, RS485 - configuration cable and power supply the wireless bridge;

Step 2: Open Modbus tool on PC
You can download Daviteq Modbus Configuration Tool with the following link:
https://filerun.daviteq.com/wl/?id=BaX6RFlaEySKSYHX2j5nYHKBgeWckrox
Unzip file and run file application "mb_master 1.1"
Choose COM Port (the Port which is USB cable plugged in)
Set the BaudRate: 9600, Parity: none

How to use the Modbus configuration software

Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the WS433-BL is being
connected with computer;
Next, we need to import the configuration file for WS433-BL by importing the csv file: Go to MENU: FILE / Import
New / => select the template file.
Step 3: We change the modbus address in column Slave (write in command 16 and read the value with
command 3)
Example 1: We read the address of Wireless Bridge Master;
Example 2: We read the address of Wireless Bridge Slave;
Please select the correct template to import into the tool

The mounting bracket is made from hard metallic material. Following to these steps as the below picture
Please wiring as shown below:
6. Installation
6.1 Mounting bracket installation
6.2 IO Wiring

Red: PWR+(12...48VDC)
Black: PWR-(OVDC)
Green: B
White: A
Recommend to use 24VDC power.
The signal cable from sensor should be protected by corrugated hose or the Φ16 plastic tube, keep the cable avoid
high temperature areas.
The bracket will be fixed on the wall or material with a flat surface with 02 x M4 screws (supplied by the customer);
Each cable includes wires which are marked labels according to types of connection. (user should not cut these
labels before installation to avoid confusing)
6.3 Installation location
Please install the device at a height of 2 meters or less.
ATTENTION:
DO NOT install the Wireless bridge or its antenna inside a completed metallic box or housing, because the RF
signal can not pass through the metallic wall. The housing is made from Non-metallic materials like plastic,
glass, wood, leather, concrete, cement…is acceptable.

No.
Phenomena
Reason
Solutions
1
Cannot read modbus
No power supply, the
power cord is incorrectly
connected;
Modbus connection pin A, B
is loose or wrong;
Configuration slave
address, baudrate, parity is
not correct;
Reading the wrong
command, wrong address
register.
Check the power
connection;
Check the connection
modbus A, B;
Check the configuration of
slave address, baudrate,
parity;
The product only supports
modbus 3, 4, and 16.
Check if the value of
modbus status returned by
2 or 3 is an incorrect
address reading.
2
Cannot add slave into master
No power supply, the
power cord is incorrectly
connected;
The antenna is not
fastened or connected;
Slave registered with
another Master.
Reset Slave with push
button or magnet;
Check the power
connection;
Disconnect the power
source and reattach, then
proceed to add
automatically.
