FTDI Industrial 8-port USB to Serial RS422 RS485 (Metal)
$299.95
The USB-8COMi-M allows you to add eight RS-422 or RS-485 serial ports by connecting to a USB port. Constructed from a rugged metal chassis for industrial applications.
Serial ports on USB allow further use of existing devices, even when the computer doesnt offer serial ports. The high speed serial port with the 128 byte FIFO allow high speed communication, even in heavy loaded systems. Unique features reduce the system load. The serial port also allows unusual speed settings like 500.000bps.
The USB-8COMi-M is a self-powered device, but it also includes a 5Volt 2Amp power supply (pictured above) for applications with high power consumption. This device offers easy plug and play installation and RS-422/RS-485 device connection. There is no need to open the chassis to set the operation modes since the eight DIP switches are located externally for easy RS-422, RS-485 mode settings.
