산업용 USB to 422/485 8 Port 변환기


OS 별 Driver 다운로드 : Windows 8.1 , Windows 7 등 Windows 모든 버전을 지원하며 Mac OS, Linux 를 지원 합니다.



The ES-U-2008-M is an 8-port USB to Serial Adapter. It quickly allows the addition of eight RS422 / RS485 serial communication ports to your system by connecting to a single USB port. Each of the 8 ports can be individually configured to RS422 or RS485 modes using DIP switches. The ES-U-2008-M is provided with an external power supply (100 V - 240 V input) and can be mounted on a DIN rail using the supplied brackets.  

 

The ES-U-2008-M is compatible with a wide range of operating systems including Windows 7, Windows Server 2008, Windows Vista, Windows XP, Windows 2000, Windows Server 2003, Mac, Linux and WinCE (4.2 – 6.0). The latest drivers are available from the Downloads tab on this page.
