Product description
USB to RS485 Adapter – for Reliable Serial Communication. The USB-RS485 is a compact and reliable adapter that enables easy connection of a PC or Linux computer to an RS485 network. RS485 is a well-established standard for serial communication in industrial environments where reliability, noise immunity, and long cable lengths are essential.
The adapter supports up to 32 nodes on a shared data bus and allows communication over twisted pair cables up to 1200 meters in length. To ensure optimal signal integrity, 120-ohm termination is required at both ends of the bus. The device uses the CH340 driver and supports data rates from 75 to 115200 bps.
