In addition: Modbus data bit 8, stop bit 1
Special note: Address 252 is used for broadcasting addresses, as long as it is used for the following situations
(1) The situation where there is only one instrument on the entire bus
At this point, the communication address of the current instrument can be set
(2) Start or stop all instruments on the entire bus
If there are multiple instruments on the bus, setting the address (register 0) with 252 address on the bus will cause all instruments on the bus to have the same address, and future communication will not be able to correctly identify a certain instrument, resulting in a malfunction of the entire system.

6、 Precautions
1. The product is equipped with a laser emitter inside, and unauthorized maintenance may result in accidental exposure of operators to laser radiation. It should be repaired by specialized personnel from the manufacturer;
2. Prohibit opening the product casing for use;
3. The product is not in direct contact with the monitoring environment (such as installed in the equipment chassis). In order to obtain accurate sampling and measurement results, please connect the air inlet to the external probe of the chassis, and the length of the connecting hose between the external probe and the inlet should be controlled within 30cm;
4. The external probe of the chassis needs to have windproof, coarse filtering, and waterproof capabilities.
