This converter lets you send and receive data using the RS485 network from your Arduino/micro controller. Similar to Serial TTL and RS232 interfaces, the RS485 lets you transfer data between micro controllers and devices but with extra features! RS485 is an industry standard protocol for data transfer and provides numerous advantages. It lets you transfer data between up to 32 devices, through the same data line over a cable length of up to 1.2km (4000ft) with a maximum data rate of 10Mbit/s. This converter is designed for office and industrial applications (non-isolated), and provides superior characteristics/features normally found only on more expensive units.
Note: For long range RS485 communication use Ground Shield Twisted Wire. D+ and D- should be twisted with each other to get optimal range.
- Lets Arduino and Microcontrollers connect to a RS485 network
