Chapter One Chapter One Introduction INTRODUCTION The 805U-E Wireless Ethernet module provides wireless connections between Ethernet devices or Ethernet wired networks (LAN’s). It has an internal 869 MHz wireless transceiver, which can be used without a radio license in Europe and South Africa. The 805U-E transmits RF power of 500mW, requiring the transmit duty-factor be limited to 10%. The 805U-E has a standard RJ45 Ethernet connection which will operate at up to 100Mbit/sec.
05U-E Wireless Ethernet User Manual An Access Point could be used as a “Repeater” unit to connect two 805U-E Clients which do not have direct reliable radio paths. Access Point LAN Client Client Ethernet device Bridge vs Router Each 805U-E is configured with an IP address for the Ethernet side, and another for the wireless side. A Bridge connects devices within the same Ethernet network - for example, extending an existing Ethernet LAN. For 192.168.0.34 192.168.0.
Chapter One Introduction There is limit of two Routers within the same radio network. There is no limit to the number of Bridges in the same network - although there is a limit of 255 Client units linked to any one Access Point. 192.168.0.34 192.168.0.72 Client Bridge 192.168.0.34 192.168.0.72 LAN A Access Point Bridge 192.168.0.73 192.168.0.74 169.254.102.17 LAN C 169.254.109.40 LAN B Client Router 1.
805U-E Wireless Ethernet Chapter Two 2.1 User Manual INSTALLATION General The 805U-E module is housed in an rugged aluminum case, suitable for DIN-rail mounting. Terminals will accept wires up to 2.5 sqmm in size. All connections to the module must be SELV. Normal 110-240V mains supply should not be connected to any terminal of the 805U-E module. Refer to Section 2.3 Power Supply. Before installing a new system, it is preferable to bench test the complete system.
Chapter Two Installation An antenna should be connected to the module via 50 ohm coaxial cable (eg RG58, RG213 or Cellfoil) terminated with a male SMA coaxial connector. The higher the antenna is mounted, the greater the transmission range will be, however as the length of coaxial cable increases so do cable losses. For use on unlicensed frequency channels, there are several types of antennas suitable for use.

Chapter Two Installation 2.5 Discrete (Digital) Input/Output The 805U-E has one on-board discrete/digital I/O channel. This channel can act as either a discrete input or discrete output. It can be monitored, or set remotely, or alternatively used to output a communications alarm status. If used as an “input”, the I/O channel is suitable for voltage free contacts (such as mechanical switches) or NPN transistor devices (such as electronic proximity switches). PNP transistor devices are not suitable.
805U-E Wireless Ethernet Chapter Three User Manual OPERATION 3.1 Start-up “Access Point” Start-up An Access Point unit starts and immediately begins transmitting periodic messages called beacons. These beacon messages are messages contain information for Clients on how to establish a link with the Access Point. Any Client that hears the messages, which are not already linked to another Access Point unit, will respond and links will be established between the new Access Point and these Clients.
Chapter Three Operation from a Client, including reassociating requests, within (12) beacon intervals, the Access Point will reset the link. After a Client has reset it’s Link status, it will start scanning for an Access Point, as if it has just started up.

This may be performed with the command: bgw h) Choose an IP address for the 805U-E being upgraded.
805U-E Wireless Ethernet 3.4 User Manual Quick Configuration The 805U-E has default configurations which will cover most applications. These parameters can be manually changed however this is not necessary for the majority of applications. A “Quick Start” configuration is provided for simple networks. This is the first stage of the module configuration. For most applications, no further configuration is required.
Chapter Three Operation an existing LAN, then you need to change the IP addresses to match your LAN addresses. • A “System Generator String” - refer to section 3.4.1 below • Radio encryption selection - None, 64-bit Proprietary or 128-bit AES - refer section 3.4.2 for more information on this. After configuring, select “Save to Flash and Reset”. 3.4.1 System Generator String The System Generator String is an alpha-numeric string of between 1 and 31 characters.
805U-E Wireless Ethernet User Manual Network Settings Webpage Fields Device Mode Used to select Bridge or Router mode. By default this is set to Bridge. Operating Mode Used to select Access Point or Client mode. By default this is set to Client. Bridge Priority The priority of the 805U-E, if configured as a bridge, in the Bridge Spanning Tree algorithm. By default this is set to the lowest priority at 255.
Chapter Three Operation Key values can be ignored. These keys will be automatically generated by the System Generator String - however the encryption keys can be manually changed. If they are manually changed, you need to make the same change to all modules in the system. Each of the fields are 5 bytes in length for 64-bit encryption and 4 bytes for 128-bit AES encryption. These keys must be entered as hexadecimal numbers separated by colons. For example, 12:AB:EF:00:56.
805U-E Wireless Ethernet User Manual can decide which traffic must be forwarded between ports - it will only transfer a message from the wired port to the wireless port if it is required. A bridge will forward all Broadcast traffic between the wired and wireless ports. If the wired network is busy with broadcast traffic, the radio network on the 805U-E can be unnecessarily overburdened. Filtering may be used to reduce broadcast traffic sent over the radio. Refer Section 3.10 for how to configure a filter.
Chapter Three Operation The factory-default settings for the radio port will be correct for the majority of applications. Only make changes if you experience operating problems. Select the “Radio” Menu to change the following configuration parameters. If a change is made, you need to select “Apply Changes and Save” to retain the changes. Power Level The RF power level is selectable between 500mW (27dBm) and 50mW (17dBm). The default value is 500mW.
805U-E Wireless Ethernet User Manual MTU size. This improvement is achieved through a reduction in the retry holdoff time required for units in the system. As packets in the system are smaller, units will holdoff for shorter periods of time and be confident that their retry transmission will not cause interference with other units. RSSI Threshold The received signal strength level at which beacons from Access Points are to be ignored.
Chapter Three Operation Counter module may attempt to increase back to the higher rate after the specified number of successful transmissions have been made. Drop Link On Retry Threshold When enabled, the module will drop radio link if all retries for sending a packet fails. When disabled, the module will only drop link on failure of regular link check transmissions, sent regularly on inactivity of 6 times the beacon interval. Disabling this item can improve usability of poor radio paths.
805U-E Wireless Ethernet Access Point Bridge Access Point Bridge User Manual Client Bridge Client Bridge For example, consider this network with a redundant wireless link. If the Spanning Tree Algorithm function is enabled, one of the two wireless links will be disabled - that is, all wireless data will be transferred by one link only. If the active link fails, the other link will automatically start transferring the wireless data. The Spanning Tree Algorithm implemented is IEEE 802.1d compatible.

805U-E Wireless Ethernet User Manual There are software packages available (i.e. 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 805U-E serial port. Standard programs can then be used to access this serial port as if it were actually connected to the PC. Alternatively the program telnet may be used to connect to a serial port on the 805U-E.
Chapter Three Operation 3.12.3 Modbus TCP to RTU Server The Modbus TCP to RTU Server allows an Ethernet Modbus/TCP Client (Master) to communicate with a serial Modbus RTU Slave. The 805U-E makes this possible by internally performing the necessary protocol conversion. The conversion is always performed by the 805U-E which is directly connected to the Modbus serial device (i.e. only this module needs to have Modbus TCP to RTU Server enabled).
805U-E Wireless Ethernet 3.14 User Manual Digital Input/Output and I/O Transfer In firmware versions v1.28 and earlier, the menu item was named Digital Input/Output. In later versions it was renamed I/O Transfer, due to enhanced functionality where units can send the status of the Digital Input to another module or Modbus device. The shared Digital Input/Output pin may be monitored and set via the internal webpage.
Chapter Three Operation The configurable Digital I/O status and alarm options are summarized below. Shared Digital I/O Status Digital Output on Communications Failure Duty Cycle Alarm The Digital I/O is a shared pin on the unit. As an output, it is similar to an open collector transistor. As an input, a short to ground is detected as ON. When the Digital Output is driven low, the Digital Input will detect an ON condition.
805U-E Wireless Ethernet User Manual port (see section “3.13.3 Modbus TCP to RTU Gateway”). Modbus TCP Client functionality allows connections to a maximum of 25 different Modbus TCP Servers. Modbus TCP Server (Client) enables the 805U-E to accept connections from one or more Modbus TCP Clients (Masters). All Modbus transactions routed to the onboard Modbus TCP Server are directed either to/from the onboard general purpose I/O registers.
Chapter Three Operation The Modbus configuration for unit C is shown below. Unit C is configured with Modbus TCP Server enabled and Device ID = 1, so that the Modbus TCP Client at B can connect and read the status of the onboard digital input. Unit C also has Modbus TCP to RTU Gateway enabled (see section “3.13.3 Modbus TCP to RTU Gateway”) so that the Modbus TCP Client at B can communicate with the serial Modbus RTU device D.
805U-E Wireless Ethernet User Manual “Reset Registers on Comms Fail” option is enabled with a timeout of 60 seconds, indicating that any of the registers at unit B will be reset if a successful Modbus transaction involving that register has not been executed in the last 60 seconds. The Modbus TCP to RTU Gateway at B must also be enabled (see section “3.13.3 Modbus TCP to RTU Gateway”) to allow Modbus communications with the serial device A.
