Ethernet to Serial device server providing access to one RS232 serial port. Data transfer rates up to 1,000,000 baud (1 MegaBaud), coupled with 1Mbit/s line drivers deliver uncompromising performance. Baud rates can be standard values such as 9,600, 115,200, 230,000, 921,600 or user definable non standard values.

Our ES range provides simple instant networked serial ports. A web interface allows secure configuration and control of the serial ports over a local network or the internet using any browser. For Windows our in-house designed (32 bit and 64 bit) driver gives you local COM ports, retaining existing software applications and allowing you to connect across your network to remote devices just as if they were attached locally.

Serial Port Tunnelling (individually configurable) allows serial cable replacement over any distance, no software required. You can access the device via TCP/IP sockets from any networked device like an Android tablet, PC or phone. On Windows OS TCP/IP sockets are handled by the Winsock API, this will differ on other OSs.
