This transparent transmission module realizes the mutual conversion of TTL signal and RS485 signal, but everyone must know that 485 is half-duplex communication. This communication method can realize two-way communication, but it cannot be carried out in both directions at the same time. Take turns alternately; that is, each end of the communication channel can be the sender or the receiver, but at the same time, information can only have one direction of transmission.
Baud rate: 110~128000bps support
Module highlights:
(1) Compatible with 3.3V and 5.0V power supply
(2) 3.3V and 5.0V signal compatible
(3) Industrial-grade design, strong anti-interference ability, and a more effective 485 lightning protection design, which can be used in industrial sites and harsh environments in the field. The working temperature is -40°C to 85°C, and the transmission distance is Up to kilometers (test with 850 meters of 2*1.5 cable, it is recommended to use within 800 meters, please add a repeater for more than 800 meters)
(4) The half-hole process design is adopted, and the thickness of the board is 0.8mm, which can be easily used as a mother board or as a solder terminal.
(5) With RXD and TXD signal indicators, you can have a panoramic view of the transceiver status
Module features:
(1) This module fully considers the 485 bus lightning protection design and anti-interference design. In the long-distance transmission in the field, connecting the "earth-to-earth" end of the module to the earth can play a good role in anti-interference and lightning protection. , Make the 485 bus safer; the indoor short-distance transmission can not be connected to the earth.
(2) The standard 2.54 pitch design is adopted to facilitate your secondary development
(3) It has a matching resistance of 120 ohms. Short-circuiting R0 can enable the matching resistance. It is recommended to short-circuit it for long-distance transmission.
(4) Support multi-machine communication, allowing connection to the bus of more than 128 devices
(5) This module can be hot-swapped, and there will be no signal plugging phenomenon caused by hot-swapping of other 485 chips
(6) Spread copper in a large area to prevent signal interference
