1.0 Overview

EtherWave - WMR

The EtherWave-WMR is a high-performance wireless ethernet bridge and serial gateway. Alternately, a Master EtherWave-WMR unit may be configured to operate as a wireless ethernet router (and serial gateway).

A BRIDGE separates two network segments within the same logical network (subnet).

A ROUTER forwards data across internetworks (different subnets).

A SERIAL GATEWAY allows asynchronous serial data to enter (as through a gate) the realm of IP communications.

The serial data is encapsulated within UDP or TCP packets.

When properly configured and installed, long range communications at very high speeds can be achieved.

The EtherWave-WMR operates within the 902-928MHz ISM frequency band, employing frequency hopping spread spectrum (FHSS) and also, for 1.1Mbps operation, digital transmission service (DTS) technology.

They provide reliable wireless ethernet bridge functionality as well gateway service for asynchronous data transfer between most equipment types which employ an RS232, RS422, or RS485 interface.

· SCADA

· remote telemetry

· traffic control

· industrial controls

· remote monitoring

· LAN extension

The small size and superior performance of the EtherWave-WMR makes it ideal for many applications. Some typical uses for this modem:

· GPS

· wireless video

· robotics

· display signs

· fleet management

1.1 Performance Features

Key performance features of the EtherWave-WMR include:

Next, the ethernet connections will be made.

continued...

Page 18

ioSelect

2.0 Quick Start

To connect an EtherWave-WMR to a PC, an ethernet CROSSOVER (not a straight-through) cable must be used.

EtherWave - WMR

The ethernet connections are dependent upon what is available to work with for the test configuration. For the purposes of this QUICK START, the assumption is that a LAN connection is available (with Internet connectivity) and that the PC is connected to this LAN.

· Disconnect the PC’s LAN connection from its NIC card and insert the now ‘loose end’ of the ethernet patchcable into the rear ETHERNET RJ45 connector at the rear of the MASTER EtherWave-WMR.

· Using a CROSSOVER cable, connect the PC’s NIC card RJ45 jack to the ETHERNET RJ45 connector on the REMOTE EtherWave-WMR.

At this point there is a wireless connection between the PC and the LAN, and you should be able to go about your typical networking activities, including accessing the Internet (via the LAN).

Also, by opening a web browser and entering the IP address of either EtherWave-WMR, you will be taken to the respective unit’s Web User Interface LOGIN window.

If communications not available as outlined above:

· Verify the RSSI LEDs on the front of each EtherWaveWMR are illuminated.

· Verify TX (red) LED activity on the front of each EtherWave-WMR.

· Observe the rear of each EtherWave-WMR, specifically the ETHERNET connection: the green LINK LED should be illuminated (indicating proper cabling) and the amber (ACTIVITY LED) should also be flickering—indicating DATA traffic at the ETHERNET connector.

· If using Windows XP, the firewall function could inhibit desired data traffic. Anti-virus software may also have a negative impact.

Initially, a remote unit’s RSSI LED’s will ‘scan’ (cycle from right to left, each LED being on for 300ms in turn). Once the unit acquires synchronization with the network, a ‘steady’ RSSI reading will be displayed.

A Master updates its RSSI indication upon receiving valid packets from remote units. It takes into consideration packets received from both Repeaters and Remotes.

When initially cabling between devices, pay close attention to the Activity LED to confirm that proper patchcable types are being used.

A Repeater will base its RSSI reading on valid packets received from Slaves; if the Slaves are silent for 2 seconds, the Repeater will display an RSSI value based on valid packets received from the Master.

Signal strength is calculated based on the last four valid received packets with correct CRC.

4.0 Operating Modes

EtherWave - WMR

An EtherWave-WMR may be configured for any operating mode: this is very convenient for purposes of sparing and becoming familiar with their configuration menus.

4.1 Master

One per network, the source of synchronization for the system. The Master controls the flow of data through the system.

4.2 Repeater

Required only if necessary to establish a radio path between a Master and Remote(s); stores and forwards the data sent to it. Synchronizes to Master and provides synchronization to ‘downstream’ units. If a local device is attached to a Repeater’s serial data port, the Repeater will also behave as a Remote (aka Repeater/Remote).

Throughout this manual, ‘Remote’ refers to a Remote as defined in Section 4.4; the general term ‘remote’ applies to an EtherWave-WMR Repeater and/or Remote - i.e.

As they are added to a radio network it is good practice to use the values 2-17, sequentially, for Repeater Unit Addresses.

Adding one or more Repeaters within a network will HALVE the throughput; the throughput is halved only once, i.e. it does not decrease with the addition of more Repeaters.

If there is a ‘radio (signal) path’ requirement to provide Repeater functionality, but throughput is critical, the repeating function may be accomplished by placing two EtherWave-WMR at the Repeater site in a ‘back-to-back’ configuration. One EtherWave-WMR would be configured as a Remote in the ‘upstream’ network; the other a Master in the ‘downstream’ network. Local connection between the modems would be accomplished with a crossover cable (for the ethernet connection). Each modem would require its own antenna; careful consideration should be given with respect to antenna placement and EtherWave-WMR configuration.

4.3 Remote

Endpoint/node within a network to which a local device is attached. Communicates with Master either directly or through one or more Repeaters. See Sections 5.3 and 5.4 for information regarding ‘Slave-to-Slave’ communications.

5.0 Network Topologies

EtherWave - WMR

The EtherWave-WMR may be configured to operate in a number of different operating modes and participate in various network topologies.

The RADIO network topology determines the paths available for the movement of data.

Take this important fact into consideration when selecting a network topology.

Note: This section describes radio network topologies in general and includes examples of corresponding Radio Configuration settings. Refer to section 6 for further detailed information regarding configuration options.

5.1 Point-to-Point (PTP)

In a Point-to-Point network, a path is created to transfer data between Point A and Point B, where Point A may be considered the Master modem and Point B a Remote. Such a PTP network may also involve one or more Repeaters (in a store-and-forward capacity) should the radio signal path dictate such a requirement. (Note that a Repeater may also concurrently function as a Remote, i.e. it may pass data to and from an attached device(s).)

A PTP configuration may also be used in a more dynamic sense: there may be many Remotes (and Repeaters) within such a network, however the Master may have its ‘Destination Address’ changed as and when required to communicate with a specific remote unit.

An example of a basic PTP network consisting of two EtherWaveWMR is on the next page.

Notes re Example 5.1.1:

· Configuration options are based upon the chosen Operating Mode of the unit: select the Operating Mode first.

· The DESTINATION UNIT for the MASTER is the UNIT ADDRESS of the REMOTE, and vice versa (noting that the MASTER’s Unit Address (not visible) is preset, and must remain as, ‘1’).

· For a PTP system, RETRANSMISSIONS on a MAS-

TER is not as critical a setting as it is in a Point-toMultipoint (PMP) system.

5.2 Point-to-Multipoint (PMP)

In a Point-to-Multipoint network, a path is created to transfer data between the Master modem and numerous remote modems. The remote modems may simply be Remotes with which the Master communicates directly, and/or Remotes which communicate via Repeaters. Some or all of the Repeaters may also act as Remotes in this type of Network, i.e. the Repeaters are not only storing and forwarding data, but are also acting as Remotes. Such Repeaters may be referred to as ‘Repeater/Remotes’.

Example 5.2.1

A 4-node network consisting of a Master, 1 Repeater, and 2 Remotes. 1 Remote is to communicate with the Master through a Repeater; the other is to communicate directly with the Master.

Refer to Section 6.1.4 for important information regarding the configuration of a PMP Master’s Retransmissions.

Image 5C: PMP Example 5.2.1: Master

· There is no DESTINATION UNIT displayed as, in PMP, the DESTINATION is preset to 65535: the BROADCAST address (‘multipoint’).

· RETRANSMISSIONS are set to 0. Refer to Section

6.1.4 for more information.

· There is a REPEATER in this example network, therefore the MASTER’s ‘Repeater’ configuration option is set to Yes.

Page 29

ioSelect

5.0 Network Topologies

EtherWave - WMR

Example 5.2.1 (continued)

When bench testing PMP with a REPEATER in the network, configure the REMOTE to synchronize to the REPEATER via the REMOTE’s ROAMING ADDRESS field. If this is not done, with the REMOTE in close proximity to the MASTER and its ROAMING set as 1 (default), the REMOTE will simply synchronize with (and pass data directly to) the MASTER, bypassing the REPEATER altogether.

Image 5D: PMP Example 5.2.1: Repeater

· The ROAMING address for the REPEATER is set to 1: the UNIT ADDRESS of the MASTER. This means that this REPEATER will synchronize to, and communicate directly with, the MASTER.

· There is no DESTINATION UNIT field for remote units in a PMP network: the destination is predefined as ‘1’ (the MASTER ‘point’).

On the following page are the configurations for the REMOTES.

· Remote 20’s ROAMING ADDRESS is set to 2, the UNIT ADDRESS of the REPEATER. This Remote will synchronize to the Repeater and communicate via the Repeater to the Master.

· Remote 30’s ROAMING ADDRESS is set to 1 (the UNIT ADDRESS of the MASTER): it will synchronize to, and communicate directly with, the MASTER.

5.3 Peer-to-Peer (P2P)

P2P mode is used for communications between pairings of remote modems,

e.g. Remote 20 can exchange data with (only) Remote 30, Remote 21 can exchange data with (only) Remote 35, etc.

A P2P network requires a Master modem.

The data being transmitted from one Remote to another in P2P mode is transferred via the Master.

The Master will resend the data incoming to it from both Remotes to both/all Remotes; one Remote’s data has a Destination Unit being the other Remote and vice versa.

Example 5.3.1

A device located at a pump station must communicate bidirectionally with another device at a water tank. The MASTER EtherWave-WMR must reside in an office at a separate location.

Image 5G: P2P Example 5.3.1: Master

All EtherWave-WMR within a particular network must be configured to have the same Network Type.

5.4 Everyone-to-Everyone (E2E)

E2E mode is used for communications between all remote modems,

i.e. data from every modem is broadcast to every other modem in the network.

An E2E network requires a Master modem.

The data being transmitted from remote units in an E2E network travels to the Master and is then re-broadcast to all other remotes.

Considering the amount of data re-broadcasting (via the Master), it is a very bandwidth-intensive network topology.

Example 5.4.1

1 Master and 3 remote units must all communicate with each other.

Image 5J: E2E Example 5.4.1: Master

· There is no DESTINATION UNIT configuration option as the DESTINATION is predefined to be the broadcast address (65535) when in E2E mode.

6.0 Configuration

EtherWave - WMR

The following factors must be considered when preparing to configure the modems:

· the application

· network topology

· physical distribution of the network

· data interface requirements

Components involved in the configuration process of the EtherWaveWMR:

· interfacing with the modem, and

· selecting and inputting the desired operational parame-

ters

Interfacing to the EtherWave-WMR for the purpose of initially configuring it may be accomplished in one of two ways:

· front COM2 connector, IoSelect Inc. DE9-RJ45 Diagnostics Cable, and a PC running terminal communications program (e.g. HyperTerminal), or

· rear ETHERNET (RJ45) port, ethernet crossover cable, and PC running IoSelect Inc. DiscoverIP utility and Web Browser application.

All configuration of the EtherWave-WMR is accomplished with a PC. There are no DIP switches to set; switches which may subsequently become inadvertently misadjusted or intermittent.

Page 36

ioSelect

6.0 Configuration

The modem will arrive from the factory with DHCP enabled and a unique random Class D IP address.

The DiscoverIP utility is utilized to ’discover’ the IP address of the EtherWaveWMR (not other devices on network) so that you may specifically address it (in Web Browser URL line) for configuration purposes.

EtherWave - WMR

6.1 Web User Interface

Initial configuration of an EtherWave-WMR using the Web User (Browser) Interface (Web UI) method involves the following steps:

· connect EtherWave-WMR ETHERNET port to PC NIC card using an ethernet crossover cable

· apply power to the EtherWave-WMR and wait approximately 1 minute for the system to load

· run IoSelect Inc. DiscoverIP Utility on the PC (see Appendix A for complete details on this convenient utility)

· within the DiscoverIP Utility window, click on the desired unit’s IP address (verify displayed MAC address with MAC address printed on sticker on bottom of unit)

· logon window appears; log on

IP Gateway

If the EtherWave-WMR devices are integrated into a network which has a defined gateway, then, as with other hosts on the network, this gateway’s IP address will be entered into this field. If there is a DHCP server on the network, and the IP Address Mode (see previous page) is selected to be DHCP, the DHCP server will populate this field with the appropriate gateway address.

A GATEWAY is a point within a network that acts as an entrance to another network.

In typical networks, a router acts as a gateway.

In a very small network (e.g. point-to-point, and STATIC IP Address Mode), the gateway value is not critical. The IP address of the most significant device on the overall network may be entered, or, if only two EtherWave-WMR’s are being used, make the gateway of EtherWave-WMR No. 1 = IP address of EtherWave-WMR No. 2; gateway of EtherWave-WMR No. 2 = IP address of EtherWaveWMR No. 1. The idea behind this approach is: If an EtherWaveWMR at ‘one end’ of a wireless link receives a packet it is unsure where to send, send it to the other end of the wireless link (i.e. the other EtherWave-WMR) where it was quite likely destined.

A simple way of looking at what the gateway value should be is: If a device has a packet of data is does not know where to send, send it to the gateway. If necessary - and applicable - the gateway can forward the packet onwards to another network.

Values

192.168.1.1

6.1.4.3 DHCP Server Configuration

There is a difference in how the DHCP Server operates based on whether the EtherWave-WMR unit (Master) is configured to function as a bridge or a router.

6.1.4.3.1 Bridge

The EtherWave-WMR Master may be configured to provide dynamic host control protocol (DHCP) service to all attached (either wired or wireless-connected) devices.

Configuration field descriptions are discussed in the following section.

6.1.4.3.2 Router

An EtherWave-WMR Master may be configured to provide dynamic host control protocol (DHCP) service for an entire LAN (or section thereof). Recall that the LAN consists of wirelessly connected EtherWave-WMR units and those IP addressable devices which are connected to them. If this feature is to be utilized, it would be enabled on the Master EtherWave-WMR unit, noting that such a DHCP Server service must not be enabled on any other EtherWave-WMR units or devices which reside on the same network segment.

With this service enabled on the Master, it can assign IP addresses (as well as subnet mask and gateway) to the LAN radios and IP devices attached to them provided they are set for DHCP as opposed to static.

The DHCP Server may also be used to manage up to five MAC address bindings. MAC address binding is employed when certain devices are to be assigned specific IP addresses (effectively issuing them a ‘static’ IP address). Such devices are identified by their unique MAC address: the DHCP Server ensures that a specified IP address is assigned to a specific MAC address (hence, device - either an EtherWave-WMR or other IP-based device attached to the LAN).

Page 56

ioSelect

6.0 Configuration

EtherWave - WMR

Prior to enabling this service, verify that there are no other devices - either wired (e.g. LAN) or wireless (e.g. another EtherWave-WMR) with an active DHCP SERVER service. (The Server issues IP address information at the request of a DHCP Client, which receives the information.)

6.1.4.4 SNMP Agent Configuration

The EtherWave-WMR may be configured to operate as a Simple Network Management Protocol (SNMP) agent.

Network management is most important in larger networks, so as to be able to manage resources and measure performance.

SNMP: Simple Network Management Protocol provides a method of managing network devices from a single PC running network management software.

Managed networked devices are referred to as SNMP agents.

SNMP may be used in several ways:

· configure remote devices

· monitor network performance

· detect faults

· audit network usage

· detect authentication failures

A SNMP management system (a PC running SNMP management software) is required for this service to operate. This system must have full access to the EtherWave-WMR network. Communications is in the form of queries (information requested by the management system) or traps (information initiated at, and provided by, the SNMP agent in response to predefined events).

Objects specific to the EtherWave-WMR are hosted under private enterprise number 21703.

An object is a variable in the device and is defined by a Management Information Database (MIB). Both the management system and the device have a copy of the MIB. The MIB in the management system provides for identification and processing of the information sent by a device (either responses to queries or device-sourced traps). The MIB in the device relates subroutine addresses to objects in order to read data from, or write data to, variables in the device.

An SNMPv1 agent accepts commands to retrieve an object, retrieve the next object, set and object to a specified value, send a value in response to a received command, and send a value in response to an event (trap).

SNMPv2c adds to the above the ability to retrieve a large number of objects in response to a single request.

SNMPv3 adds strong security features including encryption; a shared password key is utilized. Secure device monitoring over the Internet is possible. In addition to the commands noted as supported above, there is a command to synchronize with a remote management station.

Operation Mode

Select the mode of operation for the EtherWave-WMR: Master, Repeater, or Remote. An EtherWave-WMR may be configured for any role required within a radio network. This is convenient for reasons of familiarity with any/all units, as well as for hardware sparing purposes.

Master: Only one per network. For all Network Types data either originates at, is destined to, or ‘passes through’ the Master.

The selected Operation Mode will effect which configuration options are presented.

i.e. There are settings which apply to a Master which do not apply, and are therefore not presented, for a Remote.

Repeater: May act simply as a ‘Repeater’ to store and forward data to/from an upstream unit to/from a downstream unit (e.g. when there is a long distance between the latter units), or, may act as a Repeater/Remote in which case the above function is performed AND the unit may also exchange data as a Remote within the network.

If 1 or more repeaters are to be in a network, on the Master (only) the Repeater(s) YES configuration must be selected.

If 2 or more repeaters are to be in a network: the above ‘YES’ setting applies as does the requirement for Repeater Registration (discussed further on in this section).

Remote: Interfaces with remote devices and communicates with Master either directly or via Repeater(s). Communications between 2 or more Remotes is possible - through the Master - see Network Types (further on in this section, and also refer to Section

In a PMP system, set Retransmissions to the minimum value required as, effectively, the data throughput from Master to Remotes is divided by 1 plus the Retransmissions value.

EtherWave - WMR

Retransmissions

This register determines the maximum amount of times that a packet will be retransmitted (in addition to the initial transmission), noting the following specific behaviours in various network topologies:

PMP: Master will retransmit each data packet the exact number of times specified in the Retransmissions field; Remote will retransmit only if necessary, and then only until a given packet is acknowledged or the value of the Remote’s Retransmissions field is reached (after which it will discard the packet if retransmission not successful). *See also ‘PMP with ACK” described in the Network Type (below).

PTP: EtherWave-WMR will retransmit to its counterpart only if necessary, and to a maximum number of the value specified in its Retransmissions field. Packet is discarded if retransmissions are not successful.

ALL modems in a network must have the SAME value for Network Type.

Values

0-255

Network Type

Defines the type of RADIO network (see Section 5.0 for a detailed description of network topologies).

In a point-to-multipoint (PMP) network, the Master broadcasts data to all units, and all remote units send their data (ultimately) to the Master.

A point-to-point (PTP) network involves a Master and a Slave (with 0 or more Repeaters between them).

Peer-to-Peer (P2P) supports communication (through the Master) between 2 (typically remote) units.

In an Everyone-to-Everyone (E2E) network, all units communicate with all other units, through the Master. Note that this mode is very bandwidth-intensive.

continued...

Page 77

ioSelect

6.0 Configuration

Keep in mind that the Network Type determines the path that data will take.

i.e. In a PMP system, the data flows from the Master to Remotes, and from Remotes to the Master. If a ping to Remote B was sent to Remote A, it will not arrive as the data cannot travel from Remote to Remote. Similarly, a ping to a Repeater from a Remote will not arrive either: the destination for a Remote in a PMP system is the Master - not a Repeater, even though it appears in the data ‘path’ to the Master.

EtherWave - WMR

Network Type (continued)

Point-to-Multipoint with ACK is a configuration whereby the Network functions as a Point-to-Multipoint, but the Retransmissions behave as a combination of PTP and PMP in that: If retransmissions are set to 5 (for example) on the Master, and the packets it sends to the Remotes result in an ACK being received by each of the Remotes in the network, the Master will not send the data again (refer to the PMP behavior described in the preceding Retransmissions section). If, however, the Master does NOT receive an ACK from all Remotes in the network, it will then revert to sending the data again, to the maximum number of Retransmissions specified, for a period of one minute, after which time it will revert to behaving as it did originally.

This mode of operation is particularly well-suited to fixed PMP networks when multipoint operation is required as is maximum throughput.

The selected Network Type will effect the Radio Configuration menu somewhat, i.e. If Point-to-Multipoint is selected for a Remote, there is no menu item for a Destination Address as the destination is - must be - the Master (Unit Address 1).

EtherWave - WMR

Destination Unit

As the name implies, this register specifies the ultimate destination for an EtherWave-WMR’s data. Different network topologies dictate the configuration of the Destination Unit (address):

For a Remote in a Point-to-Multipoint network, this menu option will not appear: by definition, the destination is the Master (UA = 1). For the Master in PMP, its Destination Unit (Address) is 65535—the broadcast address as it sends its data to all points.

In a Point-to-Point configuration, the destination is to be specified (for a Remote: the Master); in the Master’s Radio Configuration, specify the Unit Address of the Remote Unit to which it is to send its data.

In Peer-to-Peer, the Remotes are configured with the target peer’s UA as the Destination Address, the Master with 65535; in Everyone-to-Everyone, the Destination Address for ALL units is 65535 - the broadcast address - as every unit sends its data to every other unit (through the Master). E2E is a very bandwidth intensive network topology.

Values

1-65535

This configuration option does not apply to a Master EtherWaveWMR.

On (the default) permits the EtherWave-WMR to transmit, i.e. RF emissions are enabled.

When bench testing 3 EtherWave-WMR for a Master-Repeater-Remote link, be sure to set the Remote’s Roaming Address to the Unit Address (UA) of the Repeater, and the Repeater’s Roaming Address to the UA (1) of the Master.

EtherWave - WMR

Roaming Address

This feature allows a Remote unit to synchronize with a specified ‘upstream’ unit (either Master or Repeater). The options are as follows:

65535: With this value as its Roaming Address, a Remote will synchronize with an upstream unit which has the same Network Name as the Remote. Should that upstream unit fail, this Remote will attempt to synchronize with another ’upstream’ unit within the same network (i.e. same Network Name). This ability is particularly well-suited to mobile applications.

1-254: In most static (fixed) networks, where there are no Repeaters, the default value of 1 is maintained: All Slaves synchronize to the Master (whose unit address is 1).

This will ensure that data is routed from the Remote through the Repeater to the Master; otherwise, if the Remote’s Roaming Address is left at the default value of 1, the Remote will communicate directly with the Master, bypassing the Repeater altogether.

In networks where Repeaters are present, the value of a Remote’s Roaming Address typically corresponds to the particular upstream modem with which a particular Remote is intended to communicate, e.g. Slave with Unit Address 3 may have a Roaming Address of 2, where the modem with Unit Address 2 is a Repeater between the Slave and the Master; the Repeater will have a Roaming Address of 1 as it is to synchronize to the Master.

The Roaming Address dictates to which EtherWave-WMR (by Unit Address (UA)) a Remote (or Repeater) will ’look’ or ’attach to’ for its upstream signal path.

See the description of Network Profile earlier in this section for more information about roaming-type options. The Network Profile allows for roaming between networks whereas the Roaming Address provides for roaming within a network.

With one or more Repeaters in the system, a network’s throughput is divided in half. Exercising the option of backto-back ‘Repeaters’ - which requires 2 EtherWave-WMR at a ‘Repeater’ site eliminates the division of bandwidth.

If there is more than one Repeater in a network, the Repeaters should be ‘registered’. See ‘Repeater Registration’ further along in this section re how to accomplish this.

If there are 1 or more Repeaters in the network, configure this setting as Yes.

Optimization

This setting applies to the Master only.

Optimization is a trade-off between throughput and latency.

Values

Zone Restriction

Zone restriction dictates within which band (zone) of frequencies that a particular unit will operate.

Using zones simplifies network deployment by providing a convenient reference (e.g. Zone 1) within which a given network can operate, thereby minimizing the potential for internetwork interference. This is particularly useful when used in conjunction with Network Search Mode to facilitate minimal interference among adjacently deployed networks.

Scrolling down the Radio Configuration menu reveals further configuration options: Frequency Restriction and Repeater Registration. Typically the former is not required; the latter only applies if there are 2 or more Repeaters in your network.

All modems in the network must have the same frequency restriction configured within them.

Image 6Q: Radio Configuration Menu (lower portion)

Frequency Restriction

By default, the EtherWave-WMR will hop on frequencies across the entire 902-928MHz ISM band. For some applications or within certain operating environments it may be desired to prohibit the modem from operating on specific frequencies or range(s) of frequencies.

(See Section 6.1.8.4 for a description of the Radio Channel Noise Levels tool.)

The modem will not allow ‘too many’ frequencies to be restricted; it requires a certain amount of bandwidth within which to operate to comply with regulations.

Page 85

ioSelect

6.0 Configuration

Use the Radio Channels Noise Level tool (see Section 6.1.8.4) to help identify the frequency/ range of possible interfering signals within the 902-928MHz ISM band, and then use the Frequency Restriction feature to configure the EtherWaveWMR to avoid them.

EtherWave - WMR

Frequency Restriction (continued)

The input format is:

UA: channel number, or UA: channel number-channel number z, or UA: channel number,<no space>chnl number-chnl number

where UA is the Unit Address, and

channel number is the channel number (not frequency) of the channel to be restricted.

The input formats above describe single channel, range of channels, or a combination thereof. A number of input fields may be used, or a combination of restrictions input in one field.

The image below shows an example of configuring an EtherWaveWMR (with 345kbps as an available Link Rate) with a Link Rate of 345kbps to not operate on channels 1 through 10.

Frequency Restriction (continued)

With the EtherWave-WMR having the option of, and configured for, a Link Rate of 1.1Mbps (Special Order Only), the Frequency Restriction input format remains the same (as for 345kbps described previously), however, the Channel Number must be reduced by the number of channels restricted, i.e. If Channels 1-3 are restricted, the Channel Number is to be decreased from 16 to 13, as per the following example (image below):

Image 6S: Frequency Restriction, 1.1Mbps

The Frequency Restriction ‘value’ must be input into EVERY MODEM in a network. Oftentimes the applicable Unit Address (as input in the format detailed previously) will be ‘1’ - indicating that that the Master modem - to which other units synchronize - will not be transmitting on the specified channel(s). All units in the system will use this information - as input into each one of them - to generate the appropriate hopping pattern for the network.

6.1.6 COM1 and COM2 Configuration

The menus ’COM1 Configuration’ and ’COM2 Configuration’ are used to configure the serial device server for the serial communications ports:

· COM1, the rear DE9 connector on the EtherWave-

WMR, and

· COM2, the front RJ45 connector, respectively.

Serial device data may be brought into a LAN network through TCP, UDP, or multicast; it may also exit the EtherWave-WMR network on another EtherWave-WMR’s serial port.

COM1 is a full-featured RS232 interface dedicated to serial data traffic. It supports hardware handshaking. By default, this port is enabled.

COM2 is, by default, disabled. In this state, it may be used as the console port for the text user interface. Enabled, it becomes another serial port for data traffic. It is a 3-wire (TxD, RxD, and SG) interface and does not support hardware handshaking.

For brevity, only COM1 is fully detailed in this section; the relative limitations of COM2 are noted where applicable.

Data Mode

This setting defines the serial output data framing.

In Transparent mode (default), the received data will be output promptly from the EtherWave-WMR.

When set to Seamless, the serial port server will add a gap between data frames to comply with the MODBUS protocol for example. See ‘Character Timeout’ on the next page for related information.

Values

Transparent

Character Timeout

In Seamless mode (see Data Mode described on the preceding page), this setting determines when the serial server will consider the recently-received incoming data as being ready to transmit. As per the MODBUS standard, frames will be marked as ‘bad’ if the time gap between frames is greater than 1.5 characters, but less than the Character Timeout value.

The serial server also uses this parameter to determine the time gap inserted between frames. It is measured in ‘characters’ and related to baud rate.

Character Timeout (continued)

Example: If the baud rate is 9600bps, it takes approximately 1ms to move one character. With the Character Timeout set to 4, the timeout period is 4ms. When the calculated time is less than

3.5ms, the serial server will set the character timeout to a minimum

value of 3.5ms.

If the baud rate is greater than 19200bps, the minimum character timeout is internally set to 750us (microseconds).

IP Protocol Config

This setting determines which protocol the serial server will use to transmit serial port data over the EtherWave-WMR network.

The protocol selected in the IP Protocol Config field will determine which configuration options appear in the remainder of the COMn Configuration Menu.

UDP: User Datagram Protocol does not provide sequencing information for the packets sent nor does it establish a ’connection’ (‘handshaking’) and is therefore most suited to communicating small packets of data.

TCP: Transmission Control Protocol in contrast to UDP does provide sequencing information and is connectionoriented; a more reliable protocol, particularly when large amounts of data are being communicated.

Requires more bandwidth than UDP.

TCP Client: When TCP Client is selected and data is received on its serial port, the EtherWave-WMR takes the initiative to find and connect to a remote TCP server. The TCP session is terminated by this same unit when the data exchange session is completed and the connection timeout has expired. If a TCP connection cannot be established, the serial port data is discarded.

· Remote Server Address

IP address of a TCP server which is ready to accept serial port data through a TCP connection. For example, this server may reside on a LAN network server. Default: 0.0.0.0

· Remote Server Port

A TCP port which the remote server listens to, awaiting a session connection request from the TCP Client. Once the session is established, the serial port data is communicated from the Client to the Server. Default: 20001

· Outgoing Connection Timeout

This parameter determines when the EtherWaveWMR will terminate the TCP connection if the connection is in an idle state (i.e. no data traffic on the serial port).

Default: 60 (seconds)

TCP Server: In this mode, the EtherWave-WMR will not INITIATE a session, rather, it will wait for a Client to request a session of it (it’s being the Server—it ‘serves’ a Client). The unit will ‘listen’ on a specific TCP port. If a session is established, data will flow from the Client to the Server, and, if present, from the Server to the Client. If a session is not established, both Client-side serial data, and Server-side serial data , if present, will be discarded.

· Local Listening Port The TCP port which the Server listens to. It allows a TCP connection to be created by a TCP Client to carry serial port data. Default: 20001

A UDP or TCP port is an application end-point. The IP address identifies the device and, as an extension of the IP address, the port essentially ‘fine tunes’ where the data is to go ‘within the device’.

Be careful to select a port number that is not predetermined to be associated with another application type, e.g. HTTP uses port 80.

IP Protocol Config (continued)

· Incoming Connection Timeout Established when the TCP Server will terminate the TCP connection is the connection is in an idle state. Default: 300 (seconds)

TCP Client/Server: In this mode, the EtherWave-WMR will be a combined TCP Client and Server, meaning that it can both initiate and serve TCP connection (session) requests. Refer to the TCP Client and TCP Server descriptions and settings described previously as all information, combined, is applicable to this mode.

UDP Point-to-Point: In this configuration the EtherWave-WMR will

send serial data to a specifically-defined point, using UDP packets. This same EtherWave-WMR will accept UDP packets from that same point.

· Remote IP Address IP address of distant device to which UDP packets are sent when data received at serial port. Default: 0.0.0.0

· Remote Port UDP port of distant device mentioned above. Default: 20001

· Listening Port UDP port which the EtherWave-WMR listens to

(monitors). UDP packets received on this port are forwarded to the unit’s serial port.

Default: 20001

Multicast is a one-to-many transmission of data over an IP network. It is an efficient method of transmitting the same data to many recipients. The recipients must me members of the specific multicast group.

TTL: Time to Live is the number of hops a packet can travel before being discarded.

In the context of multicast, a TTL value of 1 restricts the range of the packet to the same subnet.

UDP Point-to-Multipoint (P): This mode is configured on an EtherWave-WMR which is to send multicast UDP packets; typically, the MASTER in the EtherWave-WMR network.

· Multicast IP Address A valid multicast address this unit uses to send multicast UDP packets upon receiving data from the serial port. The default value is a good example of a valid multicast address. Default: 224.1.1.1

· Multicast Port A UDP port that this EtherWave-WMR will send UDP packets to. The Multipoint (MP - see the UDP Point-to-Multipoint (MP) description) stations should be configured to listen to this point in order to receive multicast packets from this EtherWaveWMR. Default: 20001

· Listening Port The UDP port that this unit receives incoming data on from multiple remote units. Default: 20011

· Time to Live Time to live for the multicast packets.

IP Protocol Config (continued)

UDP Point-to-Multipoint (MP): This protocol is selected on the

units which are to receive multicast UDP packets, typically the Remote units. See the previous description of UDP Point-toMultipoint (P).

· Remote IP Address The IP address of a distant device (EtherWaveWMR or, for example, a PC) to which the unit sends UDP packets of data received on the serial port. Most often this is the IP address of the Master EtherWave-WMR. Default: 0.0.0.0

· Remote Port The UDP port associated with the Remote IP Address (above). In the case of this ‘Remote’ being the Master EtherWave-WMR, the value in this field should match the Listening Port of the Master (see UDP Point-to-Multipoint (P)). Default: 20011

· Multicast IP Address A valid MULTICAST address that this unit will use to receive multicast UDP packets sent by a UDP Point-to-Multipoint (P) unit. Note that the default value for this field matches the def ault Multicast IP Address of the UDP Point-to-Multipoint (P) configuration described on the previous page. Default: 224.1.1.1

· Multicast Port The UDP port that this unit will use, along with the Multicast IP Address detailed above, to receive the multicast UDP packets sent by the UDP Point-toMultipoint (P) unit. Default: 20001
