Step 1: After supplying power the Co-ordinator via M12 connector, the Node ID must be registered within the first 5
minutes, up to 40 WS.
Step 2: Bring the wireless sensor closer to the Co-ordinator's antenna then take off the wireless sensor battery, wait
for 5s then insert the battery again. If:
Buzzer plays 1 peep sound, LED blink 1 time, that means registering Node ID on Co-ordinator successfully.
Buzzer plays 2 peep sounds, LED blink 2 times, that this Node ID is already registered.
If you do not hear the "Peep" sound, please disconnect the power the co-ordinator, wait a few minute and
try again.
Node id added in this way will be written to the smallest node_id_n address which is = 0.
Set Rssi_threshold (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL-FW_V1.9 ), default -25): The
case if Co-ordinator is on high position and need to add node sensor. We set the sensor as close as possible and set the
Rssi_threshold to -80, -90 or -100 to increase the sensitivity to allow WS433-CL-04 can add sensors at a longer
distance. After that, perform 2 steps of adding sensors and then reset Rssi_threshold = -25.
Enb_auto_add_sensors configuration (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL-FW_V1.9 )):
In case you do not want to turn off the power WS433-CL, you can set Enb_auto_add_sensors = 1, this way we have 5
minutes to add nodes (add up to 40 nodes) . After 5 minutes Enb_auto_add_sensors will automatically = 0.

In case the sensor need to be added to WS433-CL-04 (1) has been installed in a high position, the sensor
cannot be brought close to WS433-CL-04 (1). For more details:

5. Operation Principle
5.1 Add sensors node to Co-ordinator WS433-CL
5.1.1 Add Sensor Node ID automatically
5.1.2 Add sensor node into WS433-CL-04 (1) through intermediate WS433-CL-04
(2) and Modbus
Use the push button to set the data transfer speed for the first 30 seconds when the battery is first installed, after 30
seconds the push button function does not work.
Press and hold the button for 2 seconds => LED blinks once => Release the button to set Data rate RF 50kbps.
Press and hold the button for 5 seconds => LED blinks twice => Release the button to set Data rate RF 625bps.
Press and hold the button for 10 seconds => LED blinks 3 times => Release the button to reset RF parameters
(frequency, RF output power, data rate), if held for more than 30 seconds then the button function does not
work.
Reset default WS433:
Frequency: 433.92 MHz
RF transmit power: 15 dBm
RF data rate: 50 kbps
The WS433-AC wireless sensor measures AC current via CT (Current Transformer).
We need to check what the ratio on the CT is printed on the sticker. For example: 50/5A = 10, 75/5A=15, 100/5A =
20, ...
First, you need to prepare
Then, use the RS485 configuration cable to communicate with the Co-ordinator WS433-CL-04 via Modbus software (in
the link below), then write the the ratio of the CT into "Co-ordinator id" and sync with the sensor node.

5.3 Configuration
5.3.1 Sensor configuration
Unzip TOOLS-SW-EN-02.zip and run file application Daviteq Modbus Configuration Tool Version
Choose COM Port (the Port which is USB cable plugged in)
Set the BaudRate: 9600, Parity: none
Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the WS433-CL-04 is
being connected with computer.
Next, we need to import the configuration file for WS433-CL-04 by importing the csv file: Go to MENU: FILE /
Import New / => select the file with name Template for WS433-AC.csv (after unzip the file).
Wireless sensor utilize the ultra-low power 433Mhz RF signal to transmit/receive data with Wireless co-ordinator.
To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the two modules. In real
life, there is no LOS condition. However, the two modules still communicate each other, but the distance will be
reduced significantly.
Therefore, to maximize the transmission distance, please pay attention to the following conditions:
DO NOT install the wireless module inside a complete metallic box or housing. The RF signal can not pass
through metallic wall;
This wireless module would be installed a semi-metallic box, because the RF signal can pass through the non-
metal wall/are;
The best case is to install the wireless module inside or Non-metallic box;
Some non-metallic materials: plastic, glass, wood, leather, concrete, cement…
Steps for battery installation:
Using Philips screw driver to unscrew M2 screw at the side of housing
