MX485 chip is a low power consumption for RS-485 communication, limit the slew rate transceiver.
Then 5.08 (mm) pitch 2P terminal, convenient RS-485 communication wiring.
Chip leads all pins can be controlled through the microcontroller.
Operating voltage: 5V
Size: 44 (mm) x14 (mm)
Rs-485
Introduction
Intelligent instrument is with the single chip microcomputer technology mature and developed in the early 80 s, now the world instrument market basic ridge by smart meters Broken.The reason is the need of enterprise information, enterprise in one of the necessary conditions for model selection of the instrument is to have a network communication interface.First is a simple process data analog signal output quantity, later instrument interface is RS interface, this interface can realize the point-to-point communication mode, but this way cannot realize networking.Followed by the RS485, solved the problem.Let's make a brief introduction of RS485.
1. The electrical characteristics of RS - 485: logic "1" to the voltage difference between the two lines is + V (2, 6);Logic "0" for the voltage difference between the two lines - (2-6) V.Interface signal level than RS
- - C is reduced, easy damage interface circuit chip, and the level compatible with TTL level, can be convenient to TTL circuit connection.
2. RS - 485 data transfer rate of 10 megabits per second highest
3. The RS - 485 interface is the combination of using balance driver and differential receiver, enhanced ability to resist common mode of dry, good resistance to noise.
4. RS - 485 standard interface of maximum transmission distance is 4000 feet, in fact is up to 3000 meters, in addition the RS - - C interface on the bus only allowed to connect a transceiver, namely single station capacity.while
On the bus RS - 485 interface is allowed to connect up to 128 transceivers.Which have more standing ability, so that users can take
