XYR301E Wireless Ethernet User Manual
Chapter One INTRODUCTION
The XYR301-E Industrial 802.11 Wireless Ethernet module provide wireless connections between Ethernet devices and/or Ethernet wired networks (LAN’s) and complies with relevant IEEE 802.11 standard.
XYR301-E 802.11 630mW max power
The XYR301-E uses a 900 MHz Direct Sequence Spread Spectrum (DSSS) wireless transceiver. There are four bands with each band utilizing different frequencies and bandwidths dependent on the country and their radio regulations. See Section 3.1 “Selecting a Channel” for a more detailed overview.
The XYR301-E unit also provides two serial connections as well as the Ethernet connections. It is possible to use all three data connections concurrently, allowing the XYR301-E to act as a Device Server. Wireless connections can be made between serial devices and Ethernet devices. The XYR301-E provides connection functionality between serial “Modbus RTU” devices and Ethernet “Modbus TCP” devices. Appropriate driver applications will be required in the host devices to handle other protocols.
The XYR301-E has a standard RJ45 Ethernet connection which will operate at up to 100Mbit/sec. The module will transmit the Ethernet messages on the wireless band at rates between 1 and 54 Mbit/sec & 6 and 54 Mbit/sec depending on model, band, encryption methods, and radio paths.
1.1 Network Topology
The XYR301-E is an Ethernet device, and must be configured as part of an Ethernet network. Each XYR301-E must be configured as an:
“Access Point” or “Sta”, “Station”, Client”
Also needs to be configured as a:
“Bridge” or “Router”.
You can also connect to the XYR301-E via a RS232 or RS485 serial port using serial server or PPP (point-to-point) protocol. PPP allows the XYR301-E to connect serial communications into the Ethernet network.
Access Point vs Client
The Access Point unit acts as the “wireless master” unit. The Access Point accepts and authorises links initiated but client units, and controls the wireless communications.
Clients (Stations) are slave units and when connected to the Access Point becomes transparent ethernet link.
The first diagram shows a connection between two Ethernet devices using XYR301-E ethernet modems. In this example one XYR301-E is configured as an Access Point and the other as a Client - the Access Point can be connected.
Page 14 April 2012
User Manual XYR301E Wireless Ethernet
The second diagram shows an existing LAN being extended using XYR301-E’s. In this example, the Access Point is configured at the LAN end - although the wireless link will still work if the Client is at the LAN end.

.
Bridge vs Router
Each XYR301-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.
A Router connects devices on different LAN’s. The IP addresses for the Ethernet and wireless sides are different. In this example, the wireless link is part of LAN A, with the Client unit acting as a Router between LAN A and LAN B. Alternately, the Access Point could be configured as a Router - the wireless link is then part of LAN B.

If more than two routers are required within the same radio network, then routing rules may need to be configured (refer section 3.17 “Routing Rules” for further details). There is no limit to the number of Bridges in the same network - although there is a limit of 128 Client units linked to any one Access Point.

1.2 Getting Started Quickly
Most applications for the XYR301-E require little configuration. The XYR301-E has many sophisticated features, however if you don’t require these features, this section will allow you to configure the units quickly. First, read Chapter 2, “Installation”. The XYR301-E requires an antenna and a power supply.
Power the XYR301-E and make an Ethernet connection to your PC (for further information on how to do this,
refer to section 3.2 “Configuring the Unit for the first time”)
Set the XYR301-E address settings as per section 3.2 “Configuring the Unit for the first time” Save the configuration - the XYR301-E is now ready to use.
Before installing the XYR301-E, bench test the system. It is a lot easier to locate problems when the equipment is all together. There are other configuration settings, which may or may not improve the operation of the system. For details on these settings, refer to section 3.0 “Start-up”.
34-XY-25-41 Page 17
User Manual XYR301E Wireless Ethernet
Chapter Two INSTALLATION
2.0 General
The XYR301-E modules are housed in a rugged aluminium case, suitable for DIN-rail mounting. Terminals will accept wires up to 2.5 mm
All connections to the module must be SELV (Safety Extra Low Voltage). Normal 110-250V mains supply must not be connected to any terminal of the XYR301-E module. Refer to Section 2.3 Power Supply.
Before installing a new system, it is preferable to bench test the complete system. Configuration pro blems are easier to recognize when the system units are adjacent. Following installation, the most common problem is poor communications caused by incorrectly installed antennas, or radio interference on the same channel, or the radio path being inadequate. If the radio path is a problem (i.e. path too long, or obstructed), a higher performance antennas or a higher mounting point for the antenna may rectify the problem. Alternately, use an intermediate XYR301-E Module as a repeater. The XYR301-E Installation Guide provides an installation drawing appropriate to most applications. Further information is detailed below. Each XYR301-E module should be effectively earthed via the "GND" terminal on the back of the module - this is to ensure that the surge protection circuits inside are effective.

(12 gauge) in size.
2.1 Antenna Installation
The XYR301-E module will operate reliably over large distances however the achievable distances will vary with the application, radio model, type and location of antennas, the degree of radio interference, and obstructions (such as buildings or trees) to the radio path. The maximum range achievable depends on the radio model, the regulated RF power permitted in your country, and whether you use separate transmit and receive antennas.
An XYR301-E (900MHz) with a single antenna, 6.2 miles can be achieved in USA, Canada (4W ERP) and
To achieve the maximum transmission distance, the antennas should be raised above intermediate obstructions so the radio path is true “line of sight”. The modules will operate reliably with some obstruction of the radio path, although the reliable distance will be reduced. Obstructions which are close to either antenna will have more of a block ing affect than obstructions in the middle of the radio path. The XYR301-E modules provide a diagnostic feature which displays the radio signal strength of transmissions (refer Chapter 4 “Diagnostics”). 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 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. Where it is not possible to achieve reliable communications between two XYR301-E modules, then a third XYR301-E module may be used to receive the message and re-transmit it. This module is referred to as a repeater. This module may also have a host device connected to it.
The XYR301-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 left connector labelled RX is not connected unless configured under the Advanced Radio Configuration in Section 3.10. Each antenna port can be configured for TX only, RX only or Diversity (TX and RX). Selection can be made by choosing one of the options from TX Antenna / RX Antenna on the Advanced Radio Configuration page.
Note: When only one antenna is used, it must be connected to the TX/RX connector.
10km in Australia, New Zealand (1W ERP).
34-XY-25-41 Page 19
XYR301E Wireless Ethernet User Manual
Antenna Diversity
One reason to use multi antennas is because of local radio licensing regulations. All countries have a limit on the amount of transmitted power and radiated power from the antenna. In the US this is 630 milliwatts transmit power and 4 watts EIRP (Effective Isotropic Radiated Power). In a normal system if a high gain antenna is used it improves the receive signal as well as boosting the transmit signal and possibly pushing it over the EIRP regulation limit. Using Antenna diversity we can use two antennas, one for receive and the other for transmit. The receive antenna has no regulatory limits as it does not radiate power so any gain antenna can be used. To calculate the transmit antenna limit see the examples below. Example If using the XYR301-E in the US the maximum radio transmit power level will be 630mA which will allow up to 4 watts EIRP, what this means is that we can add a gain of approximately 10dB (including cable loss) without infringing the EIRP. This is calculated by using the general rule of thumb when working with dB and Power which is doubling the power is a 3dB gain. If using 10m (33ft) of Cellfoil coax cable (approximately 3dB of loss) and an 8 dBi Antenna this would equate to approximately 5dB of gain, well below our 10dB limit. If using 20m (66ft) of Cellfoil coax cable (approximately 6dB of loss) and a 15 dBi Antenna this would equate to approximately 9dB of gain, which is also below our 10dB limit. Another application where antenna diversity may be needed is in industrial plants and factories installations which can suffer from multi-path fading effects
where multiple reflected radio signals adversely affect the signal strength. In a ―static installation, where the radio path is not changing, moving an antenna to the position of maximum signal solves this problem. However where the
radio path changes because the XYR301-E is mounted on moving equipment, or if there is moving equipment in the area, then the solution is to use two antennas. Because the two connectors are separated, the RF signal at each connector will be different in the presence of multi-path fading. The XYR301-E unit will automatically select the higher RF signal provided RX diversity has been enabled on radio Config page. See Section 3.9
Advanced Radio
Configuration for details of configuring Antenna Diversity
Bench test and Demo System setup
Care must be taken with placement of antenna in relation to the radios and the other antennas. Strong radio signals can saturate the receiver, hindering the overall radio communications. When setting up a Benchtest/Demo or a short range system the following considerations should be taken into account for optimum radio performance and reduced signal saturation.
If using Demo Whip antennas (WL-DG900-1 and WL-WH900-SMA) it is recommended that only the Access
Point be fitted with an antenna.
If using Demo Whip antennas on each end, 20dB coax attenuator must be connected in-line with the coax
cable.
If using Demo Whip antennas, modules and antennas must be kept a suitable distance from each other. Check
the receive signal strength on the “Connectivity page” of the module and ensure the level is not greater than ­45dB
Demo Whip antennas should not be used in the final installation as the maximum performance of the modem cannot be guaranteed. If using a DG-900 antenna, it is better to keep the antennas at least 3ft (1m) away from the module so as to limit RF saturation.
Plant and factory installations
Another application where antenna diversity may be needed is in industrial plants and factories installations which can suffer from multi-path fading effects where multiple reflected radio signals adversely affect the signal strength. In a static installation, where the radio path is not changing, moving an antenna to the position of maximum signal solves this problem. However where the radio path changes because the XYR301-E is mounted on moving equipment, or if there is moving equipment in the area, then the solution is to use two antennas. Because the two connectors are separated, the RF signal at each connector will be different in the presence of multi-path fading. The XYR301-E unit will automatically select the higher RF signal provided RX diversity has been enabled on radio Config page.

Line-of-sight installations
In longer line-of-sight installations, the range may be increased by using a high gain antenna on the TX/RX connector. However, the gain should not cause the effective radiated power (ERP) to exceed the permitted value. A second higher gain antenna can be connected to the RX connector without affecting ERP - this will increase the operating range provided any interference in the direction of the link is low.
Antennas
Antennas can be either connected directly to the module connectors or connected via 50 ohm coaxial cable (e.g. RG58 Cellfoil or RG213) 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. 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 XYR301-E maximum net gain for US and Canada is 10dB (4W ERP) and 0dB for Australia and NZ (1 W ERP). There is no gain restriction for antennas connected to the RX connector unless “TX Diversity” is enabled on the Radio page.
The gains and losses of typical antennas are
Antenna XYR301-E Gain (dBi)
Dipole 0 dB
Collinear 5 or 8 dBi
Directional 10 – 15 dBi
Cable Loss dB per 30 m / 100 ft
RG58 Cellfoil -9 dB
RG213 -7.4 dB
LDF4-50 -2 dB
The net gain of the antenna/cable configuration is determined by adding the antenna gain and the cable loss. For example, an 8dBi antenna (5.8dBd) with 10 meters of Cellfoil (3dBd) has a net gain of 2.8dB (5.8dB – 3dB).
Installation tips
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. We recommend that the connection be taped, firstly with a layer of PVC Tape, then with a vulcanizing tape such as “3M 23 tape”, and finally with another layer of PVC UV Stabilized insulating tape. The first layer of tape allows the joint to be easily inspected when trouble shooting as the vulcanizing seal can be easily removed. Where antennas are mounted on elevated masts, the masts should be effectively earthed to avoid lightning surges. For high lightning risk areas, approved HONEYWELL surge suppression devices such as the “CSD­SMA-2500” or “CSD-N-6000” should be fitted between the module and the antenna. If using non Honeywell surge suppression devices then the devices must have a 'TURN ON' voltage of less than 90V not already shielded from lightning strike by an adjacent earthed structure, a lightning rod may be installed above the antenna to provide shielding.

Dipole and Collinear antennas
A dipole or collinear antenna transmits the same amount of radio power in all directions - as such that are easy to install and use. The dipole antenna with integral 15 ft (5m) cable does not require any additional coaxial cable; however a cable must be used with the collinear antennas. Collinear and dipole antennas should be mounted vertically, preferably 1 wavelength away (see drawing below for distances) from a wall or mast and at least 3ft (1m) from the radio module to obtain maximum range.

Directional antennas.
Directional antennas can be
a Yagi antenna with a main beam and orthogonal elements, or a directional radome, which is cylindrical in shape, or a parabolic antenna.
45
o
A directional 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. Yagi antennas should be installed with the main beam horizontal, pointing in the
Directional
Antenna
forward direction. If the Yagi is transmitting to a vertically mounted omni-directional antenna, then the Yagi elements should be vertical. If the Yagi is transmitting to another Yagi, then the elements at each end of the wireless link need to in the same plane (horizontal or vertical). Directional radomes should be installed with the central beam horizontal and must be pointed exactly in the direction of transmission to benefit from the gain of the antenna. Parabolic antennas should be mounted as per the manufacturer’s instructions, with the parabolic grid at the “back” and the radiating element pointing in the direction of the transmission. Ensure that the antenna mounting bracket is well connected to “ground/earth”.

RS485 Serial Port
The RS485 port provides for communication between the XYR301-E unit and i t s h ost de v i ce usi n g a multi-dr o p c able. U p to 32 devices may be connected in each multi-drop network. As the RS485 communication medium is shared, only one of the units on the RS485 cable may send data at any one time. Thus, communication protocols based on the RS-485 standard require some type of arbitration. RS485 is a balanced, differential standard but it is recommended that shielded, twisted pair cable be used to interconnect modules to reduce potential RFI. It is important to maintain the polarity of the two RS485 wires. An RS485 network should be wired as indicated in the diagram below and terminated at each end of the network with a 120-ohm resistor. On-board 120-ohm resistors are provided and may be engaged by operating the single DIP switch in the end plate next to the RS485 terminals. The DIP switch should be in the “1” or “on” position to connect the resistor. If the module is not at one end of the RS485 cable, the switch should be off.

3.4 Discrete (Digital) Input/Output
The XYR301-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. Contact wetting current of approximately 5mA is provided to maintain reliable operation of driving relays. The digital input is connected between the "DIO" terminal and common “COM". The I/O circuit includes a LED indicator which is lit GREEN when the digital input is active, that is, when the input circuit is closed. Provided the resistance of the switching device is less than 200 ohms, the device will be able to activate the digital input.
DIO
Voltage-free contact input
The I/O channel may also be used as a discrete output. The digital outputs are transistor switched DC signals, FET output to common rated at 30VDC 500 mA. The output circuit is connected to the "DIO" terminal. The digital output circuit in cludes a LED indicator which is lit RED when the digital output is active.

Chapter Three OPERATION
3.0 Start-up
“Access Point” Start-up
When an Access Point (AP) unit starts up it will immediately begin transmitting periodic messages, called beacons on the configured channel. Beacons include information that a Client may examine in order to identify if the Access Point is suitable fo r link establishment. Clients will only attempt to establish a link with an Access Point whose beacon indicates a matching SSID. Access Points do not initiate link establishment.
“Client” Start-up
When a Client powers up, it scans for beacons from Access Points. While a link is n ot established, the Client cyclically scans all available channels for a suitable Access Point. The Client will attempt to establish a link with an Access Point only if it has matching SSID, Encryption method, etc. and other compatible capabilities as indicated by the beacon. If more than one suitable Access Point is discovered, the client will attempt to establish a link with the Access Point that has the strongest radio signal.
Link Establishment
Once a Client identifies a suitable Access Point for link establishment it attempts to establish a link using a two step process – “Authentication” and “Association”. During Authentication the Client and Access Point check if their configurations permit them to establish a link. Once the Client has been authenticated, it will then request an Association to establish a link. Status of the wireless link is indicated via the TX/LINK LED. For an Access Point, the TX/LINK LED will be OFF while no links have been established. Once one or more links have been established, the TX/LINK LED is on GREEN. For a Client, the Link LED will reflect the connection status to an Access Point. Link status is also displayed on the “Connectivity” page of the web interface. After the link is established, data may be transferred in both directions. The Access Point will act as a master-unit and will control the flow of data to the Clients linked to it. Clients can o nly transmit data to the AP to which they are connected. When a Client transfers data to another Client, it first transmits the data to the AP, which then forward s the data to the destined Client.
Presence of a “link” does not mean that the connected unit is authorized to communicate over radio. If the encryption keys are incorrect between units in the same system, or a dissimilar encryption scheme is configured, the LINK led will light, however data cannot be passed over the wireless network. A maximum of 127 Clients may be linked to an Access Point.
How a Link connection is lost
The Access Point refreshes the link status with a Client every time a message is received from that Client. If nothing is received from a Client for a period of 120 seconds, the Access Point sends a “link-check” message. If there is no response to the link-check a De-authenticate message is sent and the link is dropped.
A Client monitors beacon messages from an Access Point to determine whether the link is still present. If the Client can no longer receive beacons from the Access Point it assumes the AP is out-of-range and the link is dropped. Whenever a Client is not connected to an AP, it will cyclically scan all available channels for a suitable AP.
Roaming Clients
Clients can roam within a system however if the link to the Access Point fails or the radio signal lev el becomes too weak it will scan for beacons and connect to an Access Point (provided the SSID and any Encryption methods, keys, etc are compatible). If there are multiple Access Points it will select the connection with the best signal level. This functionality permits a client to have mobility whilst maintaining a link with the most suitable AP.

3.1 Selecting a Channel
The XYR301-E conforms to the IEEE 802.11 Wireless LAN specification and supports various channels depending on regulations within the country of use.
If operating in the US, Canada, the frequency range is 902 to 928MHz and the available channels are:
• 9 x non overlapping 1.25MHz channels
• 9 x partially overlapping 2.5MHz channels
• 4 x non overlapping 5MHz channels
• 4 x overlapping 10MHz channels
• 2 x overlapping 20MHz channels.
If operating in Australia the frequency range is 915-928MHz and the available channels are:
• 4 x non overlapping 1.25MHz channels
• 4 x partially overlapping 2.5MHz channels
• 3 x overlapping 5MHz channels
• 1 x 10MHz channel
If operating in Hong Kong the frequency range is 922-925MHz and the available channels are:
• 2 x non overlapping 1.25MHz channels
• 1 x 2.5MHz channel
Page 28 April 2012
User Manual XYR301E Wireless Ethernet
Regions will only show the available channels for that location. See below for a diagram of the frequency ranges and channels.
Each Country/Region has a different frequency regulation with multiple band widths and numerous channels available. The main reason for having different channels and bandwidths is to allow multiple radios to operate in close proximity with minimal interference. As you can see from the Channels Diagram and the Data Throughput Table (below) the greater the band width the greater the overall data throughput. If selecting the high band width, i.e. 20MHz you will be limited to one channel which may be more susceptible to outside interference because it spans the available 900MHz frequency range, in some regions this high band width option may not even be available. If selecting the lower bands, i.e. 1.25MHz you have more channels available and each channel is non-overlapping (Adjacent channels do not cross over), however the Data throughput will be considerably lower.
If you require a high data throughput then the higher band width will need to be selected and care with antenna placement, etc will also need to be taken into account.
Selecting a 20 MHz channel will give the maximum TCP/IP throughput of around 22 Mbps however if the band width is reduced (10MHz, 5MHz, etc) the maximum data throughput will also be reduced For an indication of the data throughput levels used with different channel bandwidths see “XYR301-E Radio Data Throughput” table below.
Radio Throughput
Below is a table showing the maximum TCP/IP throughput based on channel selection and receiver signal level. There are five channel bandwidths (20, 10, 5, 2.5, & 1.25MHz). These throughput estimations are based on perfect radio conditions, i.e. little to no outside radio interference presen t while data is being passed and they are calculated using real life conditions and communication constraints. Higher data rates are achievable by using an external Iperf arrangement. For more details on this see section 4.5
Throughput Test.
