  • Page 5: Introduction

    1. Introduction The PDS-220Fx series is a family of Programmable Device Servers, also known as "Serial-to-Fiber gateways”, that are designed to enable optical fiber connectivity to be added to RS-232/422/485 devices. The user-friendly VxComm Driver/Utility allows users to easily turn the built-in COM ports of the PDS-220Fx series into standard COM ports on a PC.

  • Page 7: Why Vxcomm Technology

    1.2. Why VxComm Technology? In general, writing code for a TCP/IP program is more difficult than for a COM port program, or perhaps the COM port communication system was built many years ago. As a result, a new technology, VxComm, was developed to virtualize the COM ports of the PDS-220Fx to allow up to 256 COM ports to be used on the central computer.
  • Page 8 The VxComm driver controls all the details of the TCP/IP programming and with the assistance of PDS-220Fx and VxComm technology, your COM port program will be able to access your serial devices through the fiber optic network in the same way as it would through a standard COM port.

  • Page 9: Why Web Server Technology

    1.3. Why Web Server Technology? Web server technology enables configuration of the PDS-220Fx via a standard web browser interface, e.g. Google Chrome, Firefox, Internet Explorer or Mozilla, etc. This means that it is easy to check the configuration of the PDS-220Fx via a fiber optic network without needing to install any other software tools, thereby reducing the user’s learning curve.

  • Page 67: Glossary

    Glossary 1. ARP (Address Resolution Protocol) Consider two machines, A and B, that share a physical network. Each has an assigned IP address, IP and IP , and a MAC address, MAC and MAC . The goal is to devise low-level software that hides MAC addresses and allows higher-level programs to work only with the IP addresses.

  • Page 68: Gateway

    4. Gateway Computers that interconnect two networks and pass packets from one to the other are called Internet Gateways or Internet Routers. Gateways route packets that are based on the destination network, not on the destination host. 5. ICMP (Internet Control Messages Protocol) No system works correctly all the time.

  • Page 69: Packet

    the design and application of optical fibers. Optical fibers are widely used in fiber- optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. 10. Packet A packet is the unit of data sent across a physical network. It consists of a series of bits containing data and control information, including the source and the destination node (host) address, and is formatted for transmission from one node to another.

  • Page 70: Tcp (Transmission Control Protocol)

    15. TCP (Transmission Control Protocol) TCP provides a reliable flow of data between two hosts. It is associated with tasks such as dividing the data passed to it from applications into appropriately sized chunks for the network layer below, acknowledging received packets, setting timeouts to make certain that the other end acknowledges packets that are sent, and so on.

    3. Does the VxComm Driver (PC) support auto-reconnection after fixing a network break? Yes, the VxComm Driver (PC) supports the auto-reconnection mechanism in version 2.00 and above. The VxComm Utility allows the user to set the Keep-Alive Time (ms) and Connection-Broken Time (ms) in the server options.

  • Page 74: Why Doesn ' T Thev

    4. Why doesn't the VxComm Driver (PC) receive data from the PDS- 220Fx module? Make sure that the PDS-220Fx module is operating in mode 0 (/M0). The PDS-220Fx module uses the following communication modes: Transparent Mode (Multi-echo, shared). In this mode, data is echoed from the COM ports of the PDS-220Fx module to each client that is connected to the PDS-220Fx module.

  • Page 75: Does Transmission Speed Become Faster When A Serial Device Is Working With Serial To Fiber Optic

    5. Does transmission speed become faster when a serial device is working with Serial to Fiber optic device servers? The speed depends on the applications. For transparent applications, Ethernet latency is included in the transmission and may become slower. However, you can improve communication speed by increasing the Baud rate since you can place the device server closer to the serial device and reduce the communication distance.
  • Page 76 Xserver applications, transmission speed can become faster. Users can write their own Xserver applications to acquire data automatically, and then compress and transmit this large amount data at one time. Your application can reach a high performance by pre- acquiring data before being required by the client and then the response will be immediate.

  • Page 77: Module Fail On A Public Internet Connection

    6. Why does the PDS-220Fx module fail on a public Internet connection? The default IP address of the PDS-220Fx module is 192.168.255.1, which can only be used on a private Internet connection. A private network packet will not be routed via a public Internet connection, which is the reason why the PDS-220Fx module failed on the Internet.

    7. Can I use the SetCommState( ) API to change the Baud rate/data format settings of a virtual COM port? Yes. In a Win32 environment, the CreateFile( ) API should be called to open the COM port(s) and then the SetCommState( ) API can be used to configure the settings.
