4. Operation Principle of SENSOR TAG, WS433-TAG-01

  • The WS433-CL-07 only connected with 1 sensor WS433-TAG. If there are ≥2 nearby sensor tags, the WS433-CL-07 will receive the WS433-TAG which has the largest RSSI.
  • When WS433-CL-07 has connected to a sensor tag. At that moment, WS433-CL-07 will lock with this sensor and not accept other sensor tag even if that sensor has a bigger RSSI.
  • When WS433-CL-07 has connected to a certain sensor tag. If within 5 minutes, this sensor tag is separated and not sent data back to the WS433-CL-07. The WS433-CL-07 will return to the state with no sensor connected, then ready to connect to a new nearby sensor tag.

4.1 Insert the battery

The following batteries can be used for this sensor tag.WS433-SMT-H8.png

  • Step 1: Open the sensor cover with a Phillips screwdriver;

WS4323-TAG-03.png

  • Step 2: Insert 01 x AA 1.5 or 3.6VDC battery, please take note of the poles of the battery;

ATTENTION: REVERSED POLARITY OF BATTERY IN 10 SECONDS CAN DAMAGE THE SENSOR CIRCUIT!!!

  • Step 3: Insert the top plastic housing and locking by M2 screw.

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.

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.

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.

4.4 Datagram from Tx pin of RS232 port:

DV,[Sensor Type],[ID Sensor tag],[% sensor battery],[RF signal strength],[error code],[value 1],[value 2],[Checksum][\r\n]

- 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

    WS4323-TAG-06.png

    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.

    • Red: PWR+(7...48VDC)
    • Black: PWR-(0VDC)
    • 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.

    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.

    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.

    5.3 Datagram from Tx pin of RS232 port:

    DV,[Sensor Type],[ID Sensor tag],[% sensor battery],[RF signal strength],[error code],[value 1],[value 2],[Checksum][\r\n]

    Description Explain
    DV Product of DAVITEQ
    Sensor Type Type of sensor connected
    ID Sensor tag ID of sensor
    % sensor battery Sensor battery percentage (value = 10, 30, 60, 99%)
    RF Signal strength: 0 .. 4 (4 is strongest)
    Error code
    • 0: No error
    • 1: Error
    Value 1 and Value 2 The value of wireless sensor (wireless tag), each value has 04 bytes in HEXA
    Calculation for Checksum

    Sum of bytes in the string of { DV,[Sensor Type],[ID Sensor tag],[% of sensor battery],[RF signal strength],[error code],[value 1],[value 2], }

    → Then perform AND with 0xFF then convert to HEXA code.
    [\r\n]

    020201112 ID Sensor tag
    99 % sensor battery
    2 RF signal strength
    0 No error
    00000000 → not used for this sensor
    00000000 → not used for this sensor
    ED checksum

    2. Wireless temperature sensor WS433-M12F-ATE:

    DV,01,020201111,99,4,0,41D9999A,41D9999A,85\r\n

    Description Explain
    01 temperature sensor
    020201111 ID Sensor tag
    99 % sensor battery
    4 RF signal strength
    0 No error
    41D9999A

    Convert to Float* → 27.2°C

    *Because the sensor Type 01 specifies: both HEXA value of value 1 and value 2 are Float.

    85 checksum

    6. Installation

    All the device such as WS433-TAG-01 and WS433-CL-07 should be fixed on trailers or tractors with screws;

    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).
