Feature:
1. Wide voltage supply (3.0V~30V), limit voltage 33V, recommended to use within 30V, minimum voltage should be higher than 2.8V.
2. Compatible with 3.3V and 5.0V signals, both can match the module.
3. Excellent EMC and EMI performance.
4. With imported chips, industrial design, strong anti-interference ability, and strong 485 anti-thunder protection design, it can be used in industrial field and harsh environment in the field.
5. Operating temperature is – 40℃ to + 85℃, transmission distance can reach kilometers (test with 2*1.5 cable of 850 meters, recommended to use within 800 meters, more than 800 meters, Please add repeater).
6. With terminal and silicone wire, it is very convenient to use.
7. With RXD and TXD signal indicators, the receiving and receiving status can be seen thoroughly.

Function:
1. This module fully considers the anti-thunder protection design and anti-interference design of 485 bus. It has very high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance.
2. When long-distance transmission in the field, connecting the \"earth\" end of the module to the earth can play a very good role in anti-interference and anti-lightning, making 485 bus safer; and indoor short-distance transmission. When transporting, it may not connect to the earth.
3. With standard 2.54 spacing pin arrangement, it is convenient for your secondary development.
4. With 120ohm matching resistance, short R0 can make matching resistance possible, and it is recommended for long-distance transmission.
5. Supporting multi-computer communication, the same network can connect at least 40 nodes.
6. Hot plugging can be done without signal blocking.
7. Anti-interference routing and copper laying to prevent interference of signals.
