USB to RS232/RS485 ADAPTERS (HIGH SPEED)
Our Hi-Speed USB to RS232/RS485 adapters are an easy to use and flexible option for connecting RS232 and RS485 devices to a USB port on your computer. They use Hi-Speed USB for reduced latency and higher baud rates on the serial side.
The USB2-H-9002-M provides has two serial ports, each of which can be set individually as RS232 or half-duplex RS485 using DIP switches.
The RS232/RS485 signals are connected via convenient terminal block connections, in a robust metal enclosure with Tx/Rx and power LEDs. The units can be powered from the USB port or via an external power adapter.
- Based on the renowned FTDI FT2232H Hi-Speed USB-Serial chipset and drivers
- Microsoft Windows® WHQL-certified, macOS, Linux device drivers
- Each port can appear as a Virtual Com Port allowing easy use with existing application programs
- Ports can also be accessed using the FTDI D2xx DLL functions
- Each port has separate settings (such as RS232/RS485 mode, and parameters such as baud rate and flow control)
