Expand any PC system with a serial port

The USB Interface model 38211 converts a USB interface into a full-function serial interface. RS232, -422 and -485 devices as well as RS485 bus systems can now be connected through the USB port.

 

Interfaces:

  • 1 x USB socket, type B
  • 1 x RS232/422/485
    • 9-pin SUB-D adapter
  • Galvanic isolation between the ports
    • Isolation voltage min. 1kV DC

Management and connectivity:

  • USB 2.0 Full Speed Device (12 Mbit/s)
  • Compatible with RS485 2-wire and 4-wire bus systems
  • Automatic bus access control
  • Common solution for Windows, Linux and Mac:
    • Supports all Windows versions 98 / Server 2003 (x86 and x64 versions) and higher.
    • Supports macOS from macOS 8 and higher
    • direct Linux support without additional driver from kernel version 2.4.0

Power supply:

  • No additional power supply required
    • Voltage supply via the USB
    • Galvanically isolated power connection
  • Integrated overvoltage protection for the serial port

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3

 

Overvoltage protection for serial interfaces
The permissible voltages allowed to have an effect on serial ports in case of an error are limited to rather low values according to the data sheet specifications for the interface components. Voltages which exceed these values even for a short time will inevitably result in damage to or even destruction of the integrated circuits.

To prevent such effects the USB-Interface 38211 includes integrated overvoltage protection which uses suppressor diodes to limit the maximum occurring voltages to hamless values in a variety of application situations.
