    Programmable Serial-to-Ethernet Device Server 1. Introduction The PDS series is a family of Programmable Device Servers, also known as "Serial-to-Ethernet gateway", that are designed for linking RS-232/422/485 devices to an Ethernet network. The user- friendly VxComm Driver/Utility allows users to easily turn the built-in COM ports of the PDS series into standard COM ports on a PC.

  • Page 12: Ethernet Solutions

    Programmable Serial-to-Ethernet Device Server 1.2 Ethernet Solutions Nowadays, the Ethernet protocol has become the foremost standard for local area networks. Connectivity via the Internet is now common in many of the latest applications from home appliances, to vending machines, to testing equipment, to UPS, etc. An Ethernet network can link office automation and industrial control networks, access remote systems and share data and information between machines from multiple vendors, and also provides a cost-effective solution for industrial control networks.

  • Page 13: Vxcomm Technology

    Programmable Serial-to-Ethernet Device Server 1.3 VxComm Technology In general, writing a TCP/IP program is more difficult than writing a COM Port program. Another issue is that perhaps the existing the COM Port communication system was built many years ago and is now outdated. As a result, a new technology, VxComm was developed to virtualize the COM Ports of the PDS series to allow up to 256 COM Ports to be used on a central computer.
  • Page 14 Programmable Serial-to-Ethernet Device Server The VxComm driver controls all the details of the Ethernet TCP/IP programming technique, meaning that, with the assistance of PDS series and VxComm technology, your COM Port program will be able to access your serial devices through the Ethernet in the same way as through a COM Port.

  • Page 15: Web Server Technology

    Programmable Serial-to-Ethernet Device Server 1.4 Web Server Technology Web server technology enables the PDS series to be configured via a standard web browser interface, e.g. Google Chrome, Internet Explorer, or Firefox, etc. This means that it is easy to check the configuration of the PDS series via an Ethernet network without needing to install any other software tools, thereby reducing the learning curve required for maintaining the device.
