  • Page 4: Release Notice

    Designers must include this Important Notice in operating procedures and system manuals. These products should not be used in non-industrial applications, or life-support systems, without consulting WEIDMULLER first. • A radio license is not required in some countries, provided the module is installed using the aerial and equipment configuration described in the WI-MOD-xxx-E-5W Installation Guide.

  • Page 5: Chapter 1 - Introduction

    Weidmuller Wireless Ethernet Modem and Device Server User Manual Chapter 1 - Introduction The WI-MOD-xxx-E-5W Industrial 802.11-based Wireless Ethernet module provides wireless connections between Ethernet devices and/or Ethernet wired networks (LANs). The WI-MOD-xxx-E-5W is a fixed frequency wireless transceiver that operates within the 360 MHz to 512 MHz frequency spectrum in one of eight 20-MHz frequency bands, depending on the model purchased.
  • Page 6 Figure 2 AP and Client As the example in Figure 3 shows, an access point can connect to multiple clients. In this case, the access point should be the central unit. Figure 3 Multiple Clients An access point could be used as a repeater unit to connect two WI-MOD-xxx-E-5W clients that do not have direct reliable radio paths.

  • Page 7: Bridge Vs. Router

    Weidmuller Wireless Ethernet Modem and Device Server User Manual Bridge vs. Router Each WI-MOD-xxx-E-5W, when configured as a bridge, uses a single IP address for Ethernet and Wireless connections. A bridge connects devices within the same Ethernet network, for example, extending an existing Ethernet LAN.

  • Page 8: Getting Started

    If more than two routers are required within the same radio network, the routing rules may need to be configured (for details, see “4.9 IP Routing” on page 48). There is no limit to the number of bridges you can have in the same network, although a maximum of 128 client units can be linked to any one access point.

  • Page 9: Chapter 2 - Installation

    Weidmuller Wireless Ethernet Modem and Device Server User Manual Chapter 2 - INSTALLATION 2.1 General The WI-MOD-xxx-E-5W modules are housed in a rugged aluminum case suitable for DIN rail mounting. The terminals will accept wires up to 2.5 mm (12 gauge) in size. Before installing a new system, it is preferable to bench test the complete system.

  • Page 10: Dipole And Collinear Antennas

    • Antennas must be kept a suitable distance from each other. Check the receive signal strength on the Connectivity page of the module and ensure that the level is not greater than –45 dB. For more information, see “5.2 Connectivity” on page 70. Antennas Antennas can be either connected directly to the module connectors or connected via 50-ohm coaxial cable (such as RG58 Cellfoil or RG213) terminated with a male SMA coaxial connector.

  • Page 11: Directional Antennas

    (see Figure 11). Where antennas are mounted on elevated masts, the masts should be effectively grounded to avoid lightning surges. For high lightning risk areas, approved WEIDMULLER surge suppression devices, such as the CSD- Rev Version 1.1...

  • Page 12: Power Supply

    SMA-2500 or CSD-N-6000, should be fitted between the module and the antenna. If using non-WEIDMULLER surge suppression devices, the devices must have a “turn on” voltage of less than 90V. If the antenna is not already shielded from lightning strike by an adjacent grounded structure, a lightning rod may be installed above the antenna to provide shielding.

  • Page 18: Roaming Clients

    Roaming Clients Clients can roam within a system, but there are some limitations due to link timeouts. If the client is connected to an access point and the link fails due to a hardware problem or the signal level falls below the minimum threshold (–99 dBm, 25 kHz channel @19200 baud, or –100 dBm @ 9600 baud), the client will scan for beacon signals and connect to the access point with the strongest RSSI level (if more than one access points can be heard and provided the SSID and any encryption methods/keys are the same).

    Figure 29 Spanning Tree Protocol The Spanning Tree Protocol implemented is IEEE 802.1d compatible. The algorithm forms a loop-free network by blocking traffic between redundant links in the network. These blocked links are placed in a standby condition, and may be automatically enabled to repair the network if another link is lost. The Spanning Tree algorithm maintains a single path between all nodes in a network, by forming a tree-like structure.

    The following procedures provides instructions for performing a full USB firmware upgrade on a WI-MOD-xxx-E-5W . Requirements • USB memory stick • Firmware files (contact WEIDMULLER Technical Support to obtain these files) • Ethernet cable • PC for transferring files To prepare the USB flash drive Not all USB flash drives are configured correctly for use as a firmware upgrade drive.
  • Page 92 • If the drive contains only one partition and the “Offset” value is non-zero, as shown in the example below, you can proceed to format the drive and use it “as is” for firmware upgrade. Skip to step 7 for instructions on how to format the drive using the Diskpart utility.

  • Page 94 Do not remove the USB drive or interrupt the power to the module while the upgrade is in process. If the upgrade process is interrupted, the module may become unserviceable and need to be returned to WEIDMULLER for repair.
  • Page 95 Figure 100 Firmware Update LEDs 6. When the upgrade is complete, remove the USB drive from the WI-MOD-xxx-E-5W and replace the plastic cover. The upgrade process does not change or erase the configuration settings. 7. To verify that the firmware version has been updated and that all other configuration settings are unchanged, navigate to the home page of the Web Server on the WI-MOD-xxx-E-5W .

    Appendix C - GLOSSARY Acknowledgment. Access Point An access point connects wireless network stations (or clients) to other stations within the wireless network and also can serve as the point of interconnection between the wireless network and a wired network. Each access point can serve multiple users within a defined network area. Also known as a base station.

A set of rules used to send and receive messages across local networks and the Internet. IP address A 32-bit number that identifies each sender or receiver of information that is sent across the Internet.
  • Page 100 Transmission Control Protocol (TCP) is protocol used along with the Internet Protocol (IP) to send data in the form of individual units (called packets) between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the packets that a message is divided into for efficient routing through the Internet.

    Appendix G - EXTERNAL IPERF TEST This appendix provides instructions on how to set up and use the Iperf application to test the throughput of Ethernet modems. Iperf is a tool used to measure the throughput and quality of a network link. Jperf is an application that can be used in conjunction with Iperf to graphically display the Iperf data results.

  • Page 106: Jperf Application

    5. Enter the Iperf command “Iperf –c <IP address of Server PC> -w 65535” to start the client communication to the server. Figure 108 Iperf Client This command runs a test over the radio link to the server PC and reports back the results, as shown in Figure 109.
  • Page 107 Figure 111 Jperf Screen 3. When the Jperf screen appears, select “Client” as the Iperf Mode, and enter the IP address of the server PC. Leave the Port field at the default, and click Run Iperf. The test will run and then display the measured bandwidth (throughput) over time. You can run this test as often as needed to gather a more accurate average.
