WI-MOD-9-E Wireless Ethernet Chapter One User Manual INTRODUCTION The WI-MOD-9-E Wireless Ethernet module provides wireless connections between Ethernet devices or Ethernet wired networks (LAN’s). It has an internal 900MHz spread spectrum frequency hopping wireless transceiver, which can be used without a radio license in many countries. The WI-MOD-9-E has a standard RJ45 Ethernet connection which will operate at up to 100Mbit/sec.
Chapter One Introduction An Access Point could be used as a “Repeater” unit to connect two WI-MOD-9-E Clients which do not have direct reliable radio paths. Bridge vs Router Each WI-MOD-9-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 a Bridge, the IP address for the wireless side is the same as the Ethernet side.
WI-MOD-9-E Wireless Ethernet User Manual 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. 1.2 Getting Started Quickly Most applications for the WI-MOD-9-E require little configuration. The WI-MOD-9-E has many sophisticated features, however if you don’t require these features, this section will allow you to configure the units quickly.
Chapter Two Chapter Two Installation INSTALLATION 2.1 General The WI-MOD-9-E module is housed in a rugged aluminium case, suitable for DIN-rail mounting. Terminals will accept wires up to 12 gauge (2.5 mm²) in size. All connections to the module must be SELV. Normal 110-240V mains supply should not be connected to any terminal of the WI-MOD-9-E module. Refer to Section 2.3 Power Supply. Before installing a new system, it is preferable to bench test the complete system.
WI-MOD-9-E Wireless Ethernet User Manual Line-of-sight paths are only necessary to obtain the maximum range. Obstructions will reduce the range, however may not prevent a reliable path. A larger amount of obstruction can be tolerated for shorter distances. For very short distances, it is possible to mount the antennas inside buildings. An obstructed path requires testing to determine if the path will be reliable refer the section 6 of this manual.
Chapter Two Installation The net gain of the antenna/cable configuration is determined by adding the antenna gain and the cable loss. For example, a 6 element Yagi with 70 feet (20 meters) of Cellfoil has a net gain of 4dB (10dB – 6dB). Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture. Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the radio losses.
WI-MOD-9-E Wireless Ethernet 2.2.2 User Manual Yagi antennas. A Yagi antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to compensate for coaxial cable loss for installations with marginal radio path. The Yagi gain also acts on the receiver, so adding Yagi antennas at both ends of a link provides a double improvement. Yagi antennas are directional. That is, they have positive gain to the front of the antenna, but negative gain in other directions.
Chapter Two Installation 2.3 Power Supply The WI-MOD-9-E module can be powered from a 10 - 30VDC power supply. The power supply should be rated at 1 Amp and be CSA Certified Class 2. The negative side of the supply should be connected to a good “ground” point for surge protection. The supply negative is connected to the unit case internally. The positive side of the supply B must not be connected to earth. The RS485 DC supply may be a floating A _ supply or negatively grounded.

WI-MOD-9-E Wireless Ethernet 2.5 User Manual Discrete (Digital) Input/Output The WI-MOD-9-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).
Chapter Three Chapter Three Operation 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.
WI-MOD-9-E Wireless Ethernet User Manual Client unit does not get a response from its Access Point, it will retry the reassociation request (7) times before resetting the link. If an Access Point does not receive any traffic from a Client, including reassociation 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.
Chapter Three 3.2 Operation Default Configuration The default factory configuration of the WI-MOD-9-E is • Bridge/Client • IP address192.168.0.1XX, where XX is the last two digits of the serial number (the default IP address is shown on the printed label on the back of the module) • Subnet mask 255.255.255.
WI-MOD-9-E Wireless Ethernet 3.3 User Manual Configuring the Unit for the First Time The WI-MOD-9-E has a built-in webserver, containing webpages for analysis and modification of configuration.

WI-MOD-9-E Wireless Ethernet 3.4 User Manual Quick Configuration The WI-MOD-9-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 3.4.1 System Generator String The System Generator String is an alpha-numeric string of between 1 and 31 characters. Characters can be any ASCII alpha-numeric character (except the “null” character).
WI-MOD-9-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 WI-MOD-9-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 wireless data. The default setting is “None”. Encryption Keys 1 to 4 These are the keys used to encrypt radio data to protect data from unwanted eavesdroppers. These keys must be set the same for all WI-MOD-9-E units in the same system. If encryption is not selected, the Key values can be ignored. These keys will be automatically generated by the System Generator String - however the encryption keys can be manually changed.
WI-MOD-9-E Wireless Ethernet 3.7 User Manual Normal Operation After addresses are configured, the units are ready for operation. Refer to Section 1 for an explanation on the operation of a Bridge and Router. Transparent Bridge Operation Bridges are typically used to connect sections of the same IP network together. By default, the WI-MOD-9-E is configured as a transparent bridge.
Chapter Three Operation In some countries, the radio band is limited to a sub-set of the 902-928 MHz band to suit local regulations. In countries which allow the full 902-928MHz band (such as USA and Canada), there are eight hopping sequences, or “hop-sets” (numbered 0 to 7, user-configurable). Each sequence uses only half of the frequencies available in the band. Sequences 0-3 use the same frequencies, but in a different sequence. Sequences 4-7 use the other frequencies.
WI-MOD-9-E Wireless Ethernet Fade Margin This is the difference (in dB) between the received radio signal and the receiver sensitivity (minimum radio signal). User Manual When automatic rate is selected, the WI-MOD-9-E initially chooses a rate based on the received signal strength of transmissions. Firmware version 1.32 and later will then adjust rate on each channel to according to packet errors. Earlier versions will adjust rate based upon the received signal strength.
Chapter Three Operation improvement in overall throughput rate can be achieved by reducing 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.
WI-MOD-9-E Wireless Ethernet User Manual Fallback Probation Counter must be met also. 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.
Chapter Three Operation that the WI-MOD-9-E must handle, by placing it at the branch level in the network tree. As a branch, the WI-MOD-9-E needs only pass traffic to devices that are its “leaves”. There is some overhead in maintaining a network utilizing the Spanning Tree Algorithm. Users wishing to increase their throughput, at the expense of redundancy should disable Spanning Tree. 3.
WI-MOD-9-E Wireless Ethernet User Manual The routing rules for the Access Point in the above example are shown below. The first entry shows the route to LAN B. The gateway for the route to LAN B is configured as the wireless IP address of the WI-MOD-9-E client connected to LAN B. The destination for the route is configured as the network address of LAN B. Because the host id of the destination IP address is 0, it specifies a network address.
Chapter Three 3.12 Operation Wireless Message Filter When configured as a Bridge, the WI-MOD-9-E will transmit all broadcast messages appearing at its wired Ethernet port. When the WI-MOD-9-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.
WI-MOD-9-E Wireless Ethernet User Manual It is advisable to use the Apply Changes button to test the configuration entered. Once the configuration is determined to be correct, the Apply Changes and Save button should be used. In the event that the configuration is incorrect, a power reset will revert the unit to previously saved configuration. If an erroneous configuration has prevented all access to the module, SETUP mode may be used analyze what is wrong with the configuration.
Chapter Three Operation Delete Entries Check the delete box alongside entries selected for removal from the list. Alternatively, check the enable box alongside entries if you want to make the rule active. Whitelist or Blacklist Check the box to make the list a whitelist. This will only allow traffic described in the list to be sent over the radio link. All other traffic is blocked unless it is present in a MAC whitelist. Uncheck the box to make the list a blacklist.
WI-MOD-9-E Wireless Ethernet User Manual If you want the serial device visible as present on the Wireless or Wired network, then the local IP address must be the same as the IP address set for the desired port. A process called “Proxy ARP” is used to make the device visible on the network. In this process, the WI-MOD-9-E pretends that it holds the IP address on the network, and responds on behalf of the remote device. The result of this is similar to bridging for a single device, with some exceptions.

WI-MOD-9-E Wireless Ethernet User Manual to the ModBus/TCP Master. If no response was received serially by the WI-MOD-9-E within the configured Response Timeout, the WI-MOD-9-E will initiate a number of retries specified by the configured Maximum Request Retries. The ModBus TCP to RTU Server may be configured to operate on either the RS-232 or RS-485 port. It does not support operation on both ports at the same time.
Chapter Three 3.14 Operation 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. As this pin is shared, the Digital Input status will be ON when the Digital Output is set ON.
WI-MOD-9-E Wireless Ethernet User Manual The WI-MOD-9-E also provides ModBus TCP Client and ModBus TCP Server functionality for I/O transfer. 5000 x 16bit general purpose registers are provided for ModBus (including the onboard Digital Input/Output) and are shared for both Client and Server.
Chapter Three Operation WI-MOD-9-E with ModBus TCP to RTU Gateway enabled. Care should be taken to ensure that the Device ID (i.e. ModBus Address) of the serial device is different to the Device ID of the onboard ModBus TCP Server of the WI-MOD-9-E that the serial device is connected to. The WI-MOD-9-E provides a configurable option to automatically reset the value of the onboard I/O registers to zero in the event of a communications failure.
WI-MOD-9-E Wireless Ethernet User Manual 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. Three “ModBus TCP Client Mappings” are also configured at B in order to perform the required I/O transfer.
Chapter Three Operation Since the WI-MOD-9-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. This is a very powerful and flexible feature which could, for example, be exploited by a central monitoring facility or SCADA.
