    The 945U-E is now ready to use. Before installing the 945U-E, bench test the system. It is much easier to locate problems when the equipment is altogether. There are additional configuration settings, that may improve the operation of the system. For more information, see “3.0 Startup.”...

  • Page 11: Chapter 2 - Installation

    The 945U-E unit has two antenna connections at the top of the module, allowing for two antennas to be fitted to the module if need be. By default the right connector labeled TX/RX is the main connection used to transmitter and receiver.

    The net gain of an antenna-cable configuration is the gain of the antenna (in dBi) less the loss in the coaxial cable (in dB). The 945U-E maximum net gain for US and Canada is 10dB (4W ERP) and 0dB for Australia and NZ (1 W ERP).

  • Page 34: Wpa Enterprise - Supplicant (Client) Configuration

    A bridge connects several Ethernet networks together, and makes them appear as a single Ethernet network to higher protocol layers. By default, the 945U-E is configured as a transparent bridge. When a transparent bridge is started, it learns the location of other devices by monitoring the source address of all incoming traffic. Initially it forwards all traffic between the wired Ethernet port and the wireless port.

    945U-E will automatically drop to the next lowest data rate, and if subsequent transmissions are successful at the lower rate, the 945U-E will attempt to increase to the next highest rate. When a station connects to an access point, the two devices negotiate a data rate based on which is within the configured range of radio data rates for both devices.

    The 945U-E can be used as a PPP (Point-to-Point Protocol) server to connect the wireless system to serial devices via the RS232 or RS485 serial ports. PPP server enables a network connection to the 945U-E over a serial cable. This is much like dial up Internet. The maximum serial data rate is 115,200 bps.

  • Page 41: Modbus Tcp To Rtu Gateway

    There are software packages available (such as SerialIP Redirector by Tactical Software) that can create a virtual serial port on a PC. This virtual serial port can be configured to connect to a 945U-E serial port. Standard programs can then be used to access this serial port as if it were actually connected to the PC. Alternatively, HyperTerminal may be used to connect to a serial port on the 945U-E.

  • Page 42: Serial Menu

    The example in Figure 36 demonstrates how a Modbus/TCP client (master) can connect to one or more Modbus RTU (serial) slaves. In this example the 945U-E access point is configured with the “RS232 Modbus/TCP to RTU Gateway” enabled. Once enabled, the gateway converts the Modbus/TCP queries received from the master into Modbus RTU queries and forwards these over the RS232 port to the slave.

    Modbus TCP or RTU devices. The layout of the 945U-E I/O registers is summarized in the table below. Each register is internally saved as a 16 unsigned integer value. A Modbus transaction may access the entire 16-bit value of any register, or alternatively the most significant bit of a register may be accessed as a discrete value.
  • Page 46 The Modbus TCP client may also poll Modbus RTU (serial) devices connected to either the local serial port or a remote 945U-E serial port by enabling the Modbus TCP to RTU gateway at the corresponding serial port (see “3.10 Serial Port Configuration”).
  • Page 47 Figure 41 Modbus An example of the Modbus functionality of the 945U-E is illustrated below. In this example, the status of the onboard digital input at C will be reflected at the onboard digital output at B. Also, 8 single-bit registers from Modbus serial device D will be transferred to A.
  • Page 48 A. Since the 945U-E supports Modbus TCP client and server simultaneously, the Modbus TCP server for unit B above could also be enabled. This would allow one (or more) external Modbus TCP clients anywhere on the extended wired or wireless network to connect to unit B and monitor the status of the I/O registers, including the I/O at units A, C, and D.

    Alternatively, fixed access point to access point links can be configured for optimized throughput. Each 945U-E access point supports up to 10 separate interfaces for WDS links to other devices. Each WDS interface can be either a bridge or router interface. Refer to “1.0 Network Topology” for more information on bridge versus router.
  • Page 51 Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual Figure 45 WDS Repeaters A WDS bridge interface allows traffic to be bridged to another access point on the same IP network. WDS bridge interfaces do not require additional IP address configuration because they are bridged with the standard wireless interface that is used for connections to associated clients.
  • Page 52 Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual WDS connections are made by adding one or more virtual modules to an access point (see Figure 45). Each virtual module can be configured with one of the standard Wi-Fi operating modes (Access Point or Station) or a non- standard Point-to-Point mode.

  • Page 54 Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual Example 2: Roaming with WDS Access Points Figure 48 WDS Roaming Another common use for WDS is extending the range across a large wireless network by allowing roaming connections between access points or being able to switch to the next access point when out of range of the previous access point.
  • Page 55 Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual Figure 50 WDS Redundancy Sites A, B, C, and D can all exchange data with each other (as can all of their stations) as if they were all on the same wired segment.
  • Page 56 Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual examples. One reason why the encryption level and key would be different is that the access point may have clients that communicate using a different encryption method (for example, 128-bit WEP) and may not support the same encryption method.

  • Page 57: Routing Rules

    3.17 Routing Rules When a 945U-E receives an IP frame that is destined for an IP address on a different network, it checks if the network address matches the network address of one of its own interfaces (hard-wired Ethernet, wireless Ethernet, or WDS) and forwards the frame appropriately.
  • Page 58 Note that devices on LAN A should specify the 945U-E access point as their default gateway. An alternative to adding routing rules to the 945U-E in this example would be for each device on LAN A that needs to communicate with LANs B and C to have independent routing rules specifying the 945U-E clients at B and C as gateways to those networks.

  • Page 59: Filtering

    When configured as a bridge, the 945U-E will transmit all broadcast messages appearing at its wired Ethernet port. When the 945U-E is configured as a router, this does not occur. In many cases, the intended recipient of the broadcast traffic does not lie at the opposite end of a proposed radio link. Reducing unnecessary broadcast traffic sent over the radio link will increase available bandwidth for data.
