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.
