Function Description

Action point single point teaching TEACH A

Within the sensing range, select the first distance value as the operating point and fix the product and the target. When entering the “Teach A” mode, long press the S key to start teaching.
For the operation of analog output or 485 output, please refer to the “Operation manual”.
After teaching at the specified position, output ON from the position to the near end of the detection range.

Actual operating point: Set value * 101%; Actual exit point: Less than set value * 102%.

Operation point window teaching TEACH A, TEACH B

Within the sensing range, select the first distance value as the operating point and fix the product and the target.Enter the “Teach A” mode and then long press the S key to start teaching. After success, release the key to automatically return to the initial state of the previous level to complete the teaching of the first action point. Then enter the “Teach B” mode and then long press the S key to start teaching.
After success, release the key to automatically return to the initial state of the previous level to complete the second action point teaching. After success, release the key to automatically return to the initial state of the previous level.
For the operation of analog output or 485 output, please refer to the “Operation manual”.

If you want to return to single-point teaching after completing window teaching, only need to operate “single point teaching”, the product will automatically clear the last window teaching value.
Actual operating point: Set value * 101%; Actual exit point: Less than set value * 102%.
After teaching at the specified 2 positions, the output is ON within the range between the 2 positions.

Analog mapping: 4mA、20mA

Within the sensing range, after selecting the “current” mode, enter “4mA” or “20mA, select the first distance value as the 4mA mapping point(or 20mA mapping point), and fix the sensor and target.

The position of 4mA and 20mA(A, B) points within the effective range can be arbitrarily set, And if the distance between (a, b) points is greater than 5% of the current distance, the setting is successful. Otherwise, the setting will fail.
The default(A,B)is(4mA,20mA).For the operation of analog output, please refer to the “Operation manual”.

Data transmission (only for RS485)

Baud rate:115200(default)
Parity check: None

Data bits:8
Stop bit:1
Slave default address:0x80

Note: The default address is 0x80.Different slave addresses or different baud rates will have different redundancy checks.

Master station request message format(Command to read distance information)

Slave address	Function code	Data start address		Data volume (Unit: words)		Redundancy check CRC16-2
80	03	9C	7D	MSB:00	LSB:01	LSB:24	MSB:53

Slave station response message format:

Slave address	Function code	Bytes	Data		Redundancy check CRC16-2
80	03	02	MSB	LSB	LSB	MSB

The host computer communicates through RS485, and the sensor data readout needs to be calculated by the following method to obtain the actual measured value.
- Convert the fourth and fifth bytes in the reply packet from the slave station into decimals. The unit is mm.
- When the distance is less than 150mm, it is a blind area, and the actual measured value =150; When the distance is greater than 11000mm, the measured range is exceeded, and the actual measured value =11000;

For example: The master request message:80 03 9C 7D 00 01 24 53
The slave response message:80 03 02 09 A1 43 B2
The 4th and 5th bytes of the slave’s response message are 09 A1, converted to decimal 2465, Actual distance value=2465.

Return: If the setting is successful, the original instruction will be returned; If it fails, an error instruction will be returned.
