USB to RS485 Converter for Modbus-RTU and reliable serial data communicationSimple RS485 communication: Connects computers with a USB-A port directly to RS485 devices and bus systems. Communication takes place via a virtual COM port, allowing existing software to be used without the need for complex modifications.
Automatic data transfer: The hardware-based direction switching automatically handles the transition between transmission and reception. Configuration via RTS/CTS signals or additional software commands is not required, simplifying commissioning.
For Modbus RTU and other RS485 applications: Suitable for industrial automation, building automation, measurement and control technology, and energy monitoring. Supports baud rates from 300 to 512,000 b/s and RS485 cable lengths of up to approx. 1.2 km.
Reliable operation: The integrated 120 Ω terminating resistor reduces signal reflections on longer bus lines. ESD protection, protective diodes and resettable fuses contribute to safe operation.
High compatibility: The FTDI FT232RNL chipset supports Windows XP, 7, 8, 8.1, 10 and 11, as well as Linux, macOS, Android and Windows CE. In addition, a USB-powered 5 V output with up to 400 mA is available for devices with low current consumption.
The InLine USB to RS485 Converter connects a computer with a USB-A port to devices and networks that use an RS485 interface. Communication takes place via a virtual COM port, enabling the use of existing software without the need for extensive modifications.
The integrated FTDI FT232RNL chipset ensures reliable data transmission. The automatic hardware direction switching handles the transition between transmission and reception entirely autonomously. Configuration via RTS/CTS signals or software commands is not required.
