4. Operation Principle of SENSOR TAG,
WS433-TAG-01
4.1 Insert the battery
Step 3: Insert the top plastic housing and locking by M2 screw.
Open the cover of the sensor then 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: -10 dBm
RF data rate: 50 kbps
4.2 Button Function
The Sensor tag had been pre-configured, only use this feature if you really want to change the data
rate RF.

The WS433-TAG will send the signal to WS433-CL-07 every 60 seconds (default setting).
WS433-CL-07 sends data back to the black box according to the ASCII send_cycle configured time cycle, the default
setting is 300 seconds.
- When [error code] = 1 means that WS433-CL-07 has no wireless sensor tag connected yet.
- When the WS433-CL-07 is not connected to the WS433-TAG, if there is a sensor tag nearby, it will sends all 3 packets
with RSSI > RSSI threshold, the WS433-CL-07 receives that sensor tag and [error code] = 0, the buzzer of WS433-
CL-07 will beep once.
- When the WS433-CL-07 is not connected to the WS433-TAG, If there are ≥2 nearby sensor tags, the WS433-CL-07 will
receive the sensor tag which has the largest RSSI.
- When [error code] = 0 means that WS433-CL-07 has connected to a sensor tag. At that moment, WS433-CL-07 will
lock this sensor tag, not accept other sensor tag even if that sensor tag has a bigger RSSI.
- When [error code] = 0 means that WS433-CL-07 has connected to a certain sensor tag. If within 5 minutes, this
sensor tag is separated and not sent back to the WS433-CL-07. Then [error code] = 1 and WS433-CL-07 will return to
the state with no sensor tag connected, then ready to connect to a new nearby sensor tag.

5. Operation Principle of WS433-CL-07
5.1 IO Wiring
Each cable includes wires which are marked labels according to types of connection. (user should not cut these
labels before installation to avoid confusion).
The signal wire Tx (WS433-CL-07) will connect to the Rx (Black box) wire and vice versa.
Green: RX
White: TX
The signal cable from the sensor should be protected by a corrugated hose or the Φ16 protection tube, keep the cable
avoid high-temperature areas.
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.

5.2 Hall sensor and button function
Button and Hall sensor (using magnets for activation) have the same function and are only
available for the first 5 minutes after power on.

All the device such as WS433-TAG-01 and WS433-CL-07 should be fixed on trailers or tractors with screws;
6. Installation
ATTENTION:
DO NOT install the Wireless sensor tag inside a completed metallic box or housing, because the RF signal can
not pass through the metallic material. The housing is made from Non-metallic materials like plastic, glass,
wood,... is acceptable.
NOTE:
The WS433-TAG and WS433-CL-07 sensors should be installed as close together as possible;
The maximum distance to connect is 3 meters (If installed outside this distance, WS433-TAG and WS433-CL-07
will lose connection).
