USB <> RS485 bus system

Application:
PC controls RS485 bus system via USB

USB <> RS422/RS485

Interface USB <> RS422/RS485 industry



Product properties:

  • Industry-compatible design on account of
    • noise immunity in accordance with EN 61000-6-2
    • Galvanic isolation with an insulation voltage of min. 1 kV
    • Broad supply voltage range of 12 ... 24 V AC / DC
    • Housing for top-hat-rail installation
  • Shipped optionally with or without power supply:
    Please order power supplies as separate accessories.
  • USB 2.0 Full Speed Device (12 Mbit/s)
  • Addressable as virtual COM interface under
    Windows 98 / Me / 2000 / XP / Server 2003 / Vista / Server 2008 (x86 and x64)
  • Supports Mac OS 8, OS 9 and OS X
  • Direct Linux support without additional driver from kernel version 2.4.0

  • RS485 2 and 4 wire compatible
  • RS485 automatic mode
  • Suitable as "non-intelligent" converter for
    • RS485 field busses (e.g. Profibus, CS31, ...) <> USB

  • Conforms to standards both in office and industrial environments:
    • Increased noise immunity for industrial areas
    • Stricter noise emission for residential and commercial areas
