ATOP SE5201C Series – 1-Port Entry-Level Serial Device Server, RS-232/422/485



With ATOP’s SE5201C Series, you can transform any serial device into an Ethernet-capable one, allowing you to control and monitor your legacy serial devices via your LAN or WAN – or even over the internet.

With such connectivity, the amount of time required to configure or troubleshoot a serial device located on a factory floor or in a remote location is eliminated. And with such Ethernet-based connectivity, serial devices can be integrated into modern practices such as Industry 4.0 and IIoT, allowing you to extend their lifetime and avoid wholesale device upgrades in the near future.

Featuring 1 x software-selectable Serial Port and 1 x RJ45 Port, the SE5201C Series is a simple-to-install device, with easy configurations options such as  Telnet, Web browser, Serial Console, or other Windows utilities. And using the VirtualCOM software, Windows-based applications can access serial devices by mapping the virtual com ports to the SE5201C serial server series.

Encased in a rugged metal housing offering semi-industrial EMC protection,  the SE5201C Series is ideal for semi-industrial environments where reliability is a must, such as Warehouses, Barcode Scanners, Data Terminals, Electronic  Kanbans, Shop Floor Control Systems, and Pick-to-Light Systems.
