2. Quick Installation
You may follow the quick installation and configuration steps,
listed below, if all of the following conditions are true:
❑ You will use all of the software default values.
❑ You intend to use the Ethernet Adapter to connect an
Ethernet-ready device to an existing RangeLAN2
network.
❑ The existing network uses a Domain number between 0
and 9.
❑ You do not intend to set Security IDs on your network.
❑ You do not intend to configure the Ethernet Adapter
with an IP address.
Follow the steps below to install the RangeLAN2 792x Ethernet
Adapter:
1. Firmly screw the antenna onto its connector in a clockwise rotation. The antenna connector is located on the
side of the unit as shown in Figure 2.
Note:
Government regulatory agencies mandate that the
antenna not be alterable. Therefore, the RangeLAN2
Ethernet Adapter uses a custom antenna connector.
Do not attempt to use a non-certified Proxim antenna,
or you may damage the connector and the Ethernet
Adapter.
5
Figure 2
Attachment of the RangeLAN2 Ethernet Adapter Antenna
2. Each RangeLAN2 792x Ethernet Adapter is
preconfigured to use Domain 0. If the existing wireless
network is not using Domain 0, use the Domain rotary
switch on the underside of the RangeLAN2 Ethernet
Adapter to set the Domain number to a value between
0 and 9. If the existing network is using a Domain
number between 10 and 15, you must set the Domain
number within the software configuration menu. See
Chapter 5 for information on how to access the Ethernet
Adapter’s configuration menu.
6
3. Plug the power supply into the RangeLAN2 Ethernet
Adapter DC power jack, located on the rear panel, and
plug the power supply into an AC outlet. Upon completing this step, the LED indicator on the top panel of
the unit will glow yellow and then turn green, indicating
that the unit is ready for operation.
4. Connect one end of a standard 10BASE-T cable to an
Ethernet-ready device and the other end to the Ethernet
Adapter. If you are connecting the Ethernet Adapter to
a cabling hub, you must use a 10BASE-T cross-over
cable. See Chapter 4 for information on the pinout
specification of a 10BASE-T cross-over cable.
When the cable is correctly connected to both units, the
Link LED to the right of the Ethernet Adapter’s
10BASE-T connector will glow steady green.
5. Confirm that the yellowSync LED, located between the
serial port and the DC power jack, is on. This light
indicates that the Ethernet Adapter has synchronized to
a RangeLAN2 product acting as a Master. If this LED
light is not on, recheck the location and software settings of your Master unit.
6. Confirm that the software setting, “Filter Fixed Nodes,”
is set to “Not Filtering” on all RangeLAN2 Access
Point on the network to which the Ethernet Adapter
may roam. This step is not necessary if you are using a
RangeLAN2 Access Point model 7510, 7520, or 7521
with revision 1.4 or greater of the Access Point flash
code image installed.
7
Note:
The RangeLAN2 Access Point is shipped with Filter
Fixed Nodes set to “Filtering” by default. Unless you
are using an Ethernet Access Point (model 7510,
7520, or 7521) with revision 1.4 or greater of the
Access Point flash code image installed, this parameter must be set to “Not Filtering” in order for the
Ethernet-ready device attached to the Ethernet Adapter
to communicate with the wired network. For more
information on this requirement, please refer to Chapter 11.
7. Your RangeLAN2 Ethernet Adapter is now ready for
operation, and the Ethernet-ready device should be able
to communicate with the wired and wireless network
through the Ethernet Adapter.
If you cannot communicate between the Ethernet-ready device
and the RangeLAN2 network, compare your network settings
with the RangeLAN2 Ethernet Adapter’s default values. You
may need to adjust the Ethernet Adapter’s software parameters.
Please consult Chapter 5 for information on how to customize
the configuration of the RangeLAN2 Ethernet Adapter and
Chapter 11 for troubleshooting suggestions.
8
3. Wireless Topologies
RangeLAN2 products look and operate similar to Ethernet
products. The only difference is that a radio replaces the wire
between various nodes. This means that all of your existing
applications that operate over Ethernet will work with
RangeLAN2 without any special wireless networking software.
Wireless products are typically used in several network topologies described in this chapter.
Ad Hoc
With wireless LANs, one or more computers easily establish an
ad hoc network when the units are in range of each other. Each
computer can dynamically connect and reconnect to the others
with no additional configuration, using off-the-shelf peer-to-peer
network operating systems. With this capability, many companies are developing applications optimized for ad hoc networks.
With the addition of the Ethernet Adapter to the RangeLAN2
family, you may now connect resources to your wireless network
that previously did not support a Proxim device driver such as
printers, UNIX-based systems, and Macintosh computers.
Figure 3
Ad Hoc
9
Infrastructure
Many companies have an existing Ethernet or Token Ring LAN
infrastructure and want to be able to extend that capability to
wireless nodes. This is accomplished by attaching an Access
Point to the wired LAN. This allows the wireless clients to
access the network resources.
Figure 4
Single Ethernet AP
For larger environments, RangeLAN2 products support the
ability to roam from one wireless cell to another while maintaining the same network connection. The Access Points establish
coverage areas or cells similar in concept to those of a cellular
phone network. The mobile clients will connect with any Access Point that is within range.
10
Figure 5
Roaming on Ethernet LAN - Light Overlap
With RangeLAN2’s multi-channel architecture, Access Points
can be placed within the same cell area to increase the aggregate
throughput supported by the network. In addition, the overlapping cells offer redundancy of coverage required in networks
where downtime is not tolerable.
11
Figure 6
Roaming on Ethernet LAN- Heavy Overlap
Each RangeLAN2 Access Point within a roaming network must
be configured as a Master on a unique Channel/Subchannel pair,
but all Access Points must have the same Domain number and
Security ID. In addition, mobile clients, such as the Ethernet
12
Adapters or laptops with 7400 PC cards, are set to the same
Domain and Security ID as the Access Points. As the
RangeLAN2 mobile clients seamlessly switch from cell to cell,
the network connectivity is preserved.
The user can move freely between the RangeLAN2 Access
Points in the network. When the roaming unit leaves the transmission range of one RangeLAN2 Access Point, the software
automatically polls the other RangeLAN2 Access Point in the
same Domain to continue the network connection.
Note that the cells must overlap to ensure that there are no gaps
in coverage, and that the roaming PC will always have a connection available.
The RangeLAN2 Ethernet Adapter allows you to add printers,
computers in locations which are difficult to wire, and other
Ethernet-ready devices to the wired LAN by synchronizing to a
RangeLAN2 Access Point connected to the wired backbone.
Note:
If the Ethernet Adapter roams between Access Points
on the same network, then each Access Point must
have the “Filter Fixed Nodes” parameter set to “Not
Filtering.” However, this does not apply to RangeLAN2
Ethernet Access Points with revision 1.4 or greater of
the Access Point flash code image installed. Please
refer to Chapter 11 for details.
13
Workgroup Concentrator
In small networks, the RangeLAN2 Ethernet Adapter may be
used as a workgroup concentrator to connect up to 8 Ethernet
devices to a RangeLAN2 wireless network.
However, the Ethernet Adapter can NOT support more than 8
devices on its Ethernet port, as shown in Figure 7. The Ethernet
Adapter filters at a rate less than full Ethernet speed. This will
not pose a problem for a small network with a minimal amount
of Ethernet traffic; however, if your network has a significant
amount of Ethernet traffic or more than 8 Ethernet devices, use a
RangeLAN2 Access Point in place of the Ethernet Adapter.
Figure 7
Workgroup Concentrator
14
Since an Ethernet Adapter’s 10BaseT connector is wired to
operate like a standard Ethernet cabling hub, you must use a
10BaseT cross-over cable to connect an Ethernet Adapter to a
cabling hub. See Chapter 2 for information on the pinout specification for a 10BaseT cross-over cable.
Note that the Ethernet Adapter does NOT support roaming. A
wired network will support only one Ethernet Adapter acting as
a Master. A wireless client can not roam between two Ethernet
Adapters. However, an Ethernet Adapter, configured as a
Station, can roam between RangeLAN2 Access Points.
If your networking needs require greater wireless coverage than
what is provided by a single Ethernet Adapter, use multiple
RangeLAN2 Access Points in place of the Ethernet Adapter.
15
Repeating
You have the option to enable or disable repeating. When
repeating is enabled, the RangeLAN2 Ethernet Adapter, set as a
Master, will repeat any signal coming from one Station and
destined for another Station, when the two Stations are both
within range of the Master, but not within range of one another.
The advantage of repeating is the ability to double the effective
range of the RangeLAN2 network. However, be aware that by
enabling the repeating feature, the network throughput will drop
by as much as one-half when repeating occurs. When repeating
is disabled, the RangeLAN2 Ethernet Adapter will not repeat the
signals of Stations synchronized to it. By default, repeating is
disabled.
Figure 8
Repeating

4. Understanding the Hardware
Rotary Switches
The RangeLAN2 Ethernet Adapter is designed for easy configuration by setting two rotary switches located on the bottom of
the unit. The rotary switches are shown in Figure 9 below. Use
the switch setting tool, enclosed in the product package, to
change the position of the rotary switches.
❑ The Station/Master Switch allows the user to externally
set the unit’s Station Type to either a Master or a Station within a wireless network. The Ethernet Adapter is
pre-configured so that the switch is set as a Station.
❑ The Domain Switch allows the user to set the Domain
number to a value between 0 and 9. The Ethernet
Adapter is preconfigured to operate using Domain 0. If
you want to set the Domain to a number between 10 and
15, you must use the software configuration menu. See
Chapter 5 for information on how to access the Ethernet
Adapter’s software configuration menu.

LED Indicators
There are three LEDs on the top panel of the RangeLAN2 792x
Ethernet Adapter:
❑ The Status LED on the right side (with the unit orientated so that you can read the Proxim logo), changes
colors from yellow (initializing) to green (operational).
This LED will blink red in a repeating pattern if a
problem occurs with the unit during operation. See
Chapter 11 for a further discussion of these patterns.
18
❑ The Radio LED in the center blinks yellow when the
Ethernet Adapter is transmitting data packets over its
radio.
❑ The Ethernet LED on the left side blinks green when the
Ethernet Adapter is transmitting data over the 10BASET Ethernet port.

Status LED
There are also four LEDs on the back panel of the RangeLAN2
792x Ethernet Adapter:
❑ The green “Master” LED, located between the DC
power jack and the serial interface, is on steady when
the unit is set as a Master.
❑ The yellow “Sync” LED, located between the DC
power jack and the serial interface, is on steady when
the unit is set as a Station and is synchronized to a
Master.
❑ The green “Link” LED, located between the serial
interface and the 10BASE-T connector, is on steady to
indicate an Ethernet link between the Ethernet Adapter
and the Ethernet-ready device. This LED blinks when
the unit sends packets through its Ethernet port. Note
that this LED will blink on occasion even if a proper
10BASE-T cable is not connected.
❑ The yellow “Override” LED, located between the serial
interface and the 10BASE-T connector, is on steady
when the Station Type and Domain parameters configured by the software interface override those set by the
external rotary switches.

10BASE-T Connector Specification
The 10BASE-T connector located on the back panel of the
Ethernet Adapter (see Figure 11, above) is wired like a cabling
hub and connects to any Ethernet Network Interface Card using
a standard 10BaseT cable. Standard 10BASE-T specifications
apply to the 10BASE-T interface of the Ethernet Adapter. No
segment can exceed 100 meters.
If you intend to plug the Ethernet Adapter directly into a cabling
hub, you must use a 10BASE-T cross-over cable. A cross-over
cable differs from a standard 10BASE-T cable in that pins 1 and
3 and pins 2 and 6 are crossed. Figure 12 below demonstrates
the pinout for a 10BASE-T cross-over cable.

Antenna Options
The Ethernet Adapter is shipped with a standard directly-connected antenna. To install the antenna, screw it clockwise onto
the antenna connector. Proxim sells several antenna alternatives,
including higher gain omnidirectional and directional antennas.
Each of these antennas ship with installation and mounting
instructions. For information on additional antenna options,
please contact your Proxim Sales Representative.
Mounting Options
The Ethernet Adapter was designed to sit on a flat surface.
However, there are four pre-threaded holes on the underside of
the unit so that it may be mounted on any surface. The mounting
holes are shown Figure 14. These holes are a #6-32 tap and
0.175" deep. Screws and mounting tools are not provided by
Proxim.
Note:
When mounting the Ethernet Adapter onto a flat
surface, you may need to remove the plastic feet from
the underside of the unit so that the mounting holes are
flush against the mounting surface. The plastic feet
are glued onto the underside of the unit and can be
removed with a small flat-head screwdriver.

5. Software Configuration
You need to configure the RangeLAN2 Ethernet Adapter using
the software menus if any of the following conditions apply:
❑ You want to set Security IDs on your network or your
existing network uses a Security ID.
❑ You want to set the Domain number to a value between
10 and 15.
❑ You want to assign the Ethernet Adapter an IP address.
❑ You need to change any of the software default values.
In order to configure an Ethernet Adapter, you need a terminal or
terminal emulation program, such as Hyperterminal or
Quarterdeck’s Procomm Plus, to access the Ethernet Adapter
configuration menu. Hyperteminal is shipped with Microsoft
Windows 95.
Displaying the Configuration Menu

Please note that changes to these parameters will not take affect
until either the radio or the Ethernet Adapter is reset.
A RangeLAN2 Ethernet Adapter may be set as either a Master or
a Station using the Station Type parameter within the configuration menu. You may also choose “U” for Use Switch to use the
value specified by the Station/Master rotary switch. The rotary
switch is set to Station by default.
Proxim’s RangeLAN2 products are frequency hopping spread
spectrum radios which communicate in the 2.4GHz frequency
band. This means that several times every second, the frequency
at which the units are communicating changes.
In order for the units to communicate, in each subnetwork there
must be one unit that coordinates the frequency hops. This unit
is called the Master. It might help you to think of the Master as
the conductor of a frequency hopping orchestra. The Master
keeps time so all units know when to hop and to what frequency.
Units classified as Stations synchronize to the Master and follow
its signal to learn what frequency in the pattern the Master is
currently using.
There must be at least one unit on the network designated as the
Master. In an Ad Hoc topology, there is only one master, but it
does not matter which unit is designated as the Master. However, in topologies where a RangeLAN2 Access Point is present,
the Access Point will be the Master and each Ethernet Adapter
should be set as a Station.
In small networks where a RangeLAN2 Ethernet Adapter is used
as a Workgroup Concentrator, the Ethernet Adapter will be
configured as the Master and all other wireless units will be
configured as Stations.
33
In order to establish communication, all Stations and the Master
must be configured with the same Domain number. Radios on
different Domains cannot communicate with each other. The
Domain is a software filter which does not affect the actual radio
frequency or the frequency hopping sequence.
You may want to set everyone on your network to the same
Domain. For larger wireless networks, use the Domain to
establish roaming subnetworks throughout your building. For
example, the Engineering Department may use Domain 2, and
the Sales Department may use Domain 5. Then engineers can
only roam within the geographical area mapped out by
RangeLAN2 Access Points with a Domain setting of 2.
The Domain is a number between 0 and 15. Choose “U” for Use
Switch in order to use the number specified by the Domain
rotary switch. The default setting is the rotary Domain switch
which shipped from the factory set to Domain 0.
Note that while the rotary Domain switch allows the user to set
the Ethernet Adapter to operate on a Domain number between 0
and 9, the software configuration menu allows the user to set the
Domain to a number between 0 and 15. If you want to use a
Domain number between 10 and 15, you must configure this
parameter within the software configuration menu.
Each Master can select one of 15 Channels to establish communication with its Stations. Each Channel number sets a unique
frequency hopping sequence allowing for multiple subnetworks
with higher data rate transmission capability in the same air
space. You may think of the Channel as a pipe. In order to
communicate, radios must be on the same Channel and there
must be one (and only one) Master that provides the timing for
that Channel.
34
There are 15 independent Channels designated 1 through 15.
This means that there are 15 different sequences of frequency
hops. Each Channel is at a different frequency at a different
time. To minimize interference, set each Ethernet Adapter
acting as a Master within the same area to a different Domain
and Channel. In networks with multiple Access Points, set each
Access Point to a different Channel but the same Domain to
facilitate roaming.
The Ethernet Adapter’s Channel may be set to a value between 0
and 15, and 0 is the default setting. When set to Channel 0, an
Ethernet Adapter automatically selects a Channel upon boot-up
based on the configured Domain number. The Channel selected
is the Domain number plus 1. Therefore, if the Domain is set to
0, the Channel is 1. Note that the automatic selection procedure
will choose Channel 15 when set to either Domain 14 or 15.
This parameter is visible only when the Ethernet Adapter is set
as a Master. All Stations will determine their channel by the
Master to which they are synchronized.
The Subchannel is a software code that is appended to each
radio packet. It does not affect the frequency hopping sequence
like a Channel does. Use a Subchannel if you need more than 15
Masters in the same area and, therefore, all the Channels are
used. The Subchannels are designated 1 through 15, and 1 is the
default setting. This parameter is visible only when the Ethernet
Adapter is set as a Master.
For example, you can use Channel 1, Subchannel 1 for Network
A and Channel 1, Subchannel 2 for Network B. The two networks will not communicate with one another. They are, however, still sharing the 1.6 Mbps data rate since they are both
using Channel 1.
35
The optional Master Name parameter of up to 11 characters
specifies an alphanumeric name to simplify the identification of
each Master in your network. You may not have spaces in the
name. This parameter is visible only when the Ethernet Adapter
is set as a Master.
To further improve the security of a wireless subnetwork, each
unit requires the same Security ID to establish communication.
The Security ID is used on all RangeLAN2 products and all
Station Types. This ID is encrypted and stored within the
RangeLAN2 Ethernet Adapter itself, not in software. It cannot
be accessed, but you may change it. However, if you do change
it, then you will need to change the Security ID on all of the
other radios to the same new value to reestablish communication.
The Security ID parameter can be up to 20 characters and is an
empty string by default. There are 1,048,576 unique choices for
the Security ID.
Note:
The Security ID value is not a software parameter but
is stored within the Ethernet Adapter’s radio. Therefore, if you choose the Reset Parameters to Factory
Defaults option from within the Ethernet Adapter
Main Menu, the Security ID will not be reset to its
default value.
The Repeating Enabled parameter gives the ability to enable or
disable the RangeLAN2 repeating feature. When enabled, a
RangeLAN2 Ethernet Adapter, acting as a Master, will repeat
signals coming from one Station and destined for another Station. These two Stations must be out of range of one another,
but both in range of the RangeLAN2 Ethernet Adapter for
repeating to occur.
36
However, be aware that by enabling the repeating feature, the
network throughput will drop by as much as one-half when
repeating occurs.
This parameter is only visible when the Ethernet Adapter is
configured as a Master. By default, Repeating is disabled. See
Chapter 3 for more information on Repeating.
The MAC Optimize parameter can help improve throughput for
small networks. The default setting of Auto allows the
RangeLAN2 Ethernet Adapter to determine the number of units
synchronized to it and to then adjust this parameter accordingly.
Alternately, you may force the parameter to one of the other
settings. If you have 0 or 1 wireless nodes communicating with
an Ethernet Adapter, use the Very Light setting. If you have
between 2 and 7 wireless nodes communicating with an Ethernet
Adapter at the same time, use Light. (You can have more than 7
nodes synchronized to an Ethernet Adapter but between 2 and 7
communicating at the same time for the Light parameter setting.)
In networks with more than 7 concurrent wireless users, use
Normal. The MAC Optimize parameter is visible only when the
Ethernet Adapter is set as a Master.
To conserve power, the RangeLAN2 Ethernet Adapter has an
Inactivity Timeout doze mode for the radio. The doze mode is
automatically engaged when a certain period of time has elapsed
since the unit has sent or received data over its radio. An
Ethernet Adapter in doze mode will wake up when a Master unit
attempts to send data to it.
There is no inactivity timeout set by default, but you may
change this to any interval of 10 seconds. This parameter is
visible only when the Ethernet Adapter is set as a Station.
37
The Roam Config parameter allows you to determine how
quickly an Ethernet Adapter, set as a Station, will roam from one
Master Access Point to another. In areas with many
RangeLAN2 Access Points that provide heavy overlapping
coverage, set this parameter to Fast to maintain high throughput
for each of the wireless nodes.
In most networks, set the Roam Config parameter to Normal.
Wireless node throughput will not change noticeably, and an
overabundance of RangeLAN2 Access Points is not required.
If the wireless coverage area provided by RangeLAN2 Access
Points is sparse, set the Roam Config parameter to Slow. Wireless nodes will not roam until they are nearly out of range of the
RangeLAN2 Access Point to which they are synchronized. This
parameter is visible only when the Ethernet Adapter is set as a
Station.
Note:
Note that wireless clients can NOT roam between
multiple Ethernet Adapters set as Masters or between
a RangeLAN2 Access Point and an Ethernet Adapter.
RangeLAN2 products only support roaming between
Access Points and Extension Points.
You may choose to disable a RangeLAN2 Ethernet Adapter’s
ability to roam from one Master RangeLAN2 Access Point to
another with the Roaming Enabled parameter. This feature is
enabled by default and is visible only when the Ethernet Adapter
is set as a Station.

Set IP Address allows you to assign the Ethernet Adapter a
unique network IP address. If the unit is attached to an Ethernetready device, do not assign the Ethernet Adapter the same IP
address as the Ethernet-ready device. The Ethernet Adapter
must have its own IP address if you choose to give it one.
Note:
The IP Address parameter is provided for diagnostic
purposes so that a remote system may ping the Ethernet
Adapter.
The Forwarding Database Table Timeout parameter allows
you to control the length of time the Ethernet Adapter will hold a
learned address of a network node in its Forwarding Database
Table. This data is dynamically acquired by the RangeLAN2
Ethernet Adapter so that it can forward packets properly to wired
and wireless nodes. By default, a Forwarding Database Table
entry will expire after 300 seconds or 5 minutes.
40
The CPU Power Save Mode parameter will reduce the amount
of power drawn by the Ethernet Adapter during operation. This
is a useful feature for customer who are powering the Ethernet
Adapter with a battery.
Note:
Enabling the CPU Power Save Mode will reduce the
Ethernet Adapter’s rate of data transfer.
The Ethernet Adapter’s serial port supports three Echo Modes
when configuring the unit through a terminal session: None,
Simple, and Terminal. When set to None, the Ethernet Adapter
will not echo typed characters to the terminal screen. When set
to either Simple or Terminal, all characters typed are echoed to
the screen during a terminal session. The Ethernet Adapter is set
to Terminal mode by default. This parameter will only affect the
appearance of data within the configuration menu; it plays no
role in normal operation.
The Ethernet Adapter configuration menu contains several
parameters that are not needed for normal operation. A password is needed to enable Technical Support Access to view
these settings.
If you call Proxim Technical Support, they may ask you to
enable the Technical Support parameters, but, in general, you
will not need to access these parameters.
41

8. Display Parameter Values
The Ethernet Adapter displays all of the relevant parameters in
one centralized location. By choosing “Display Parameter
Values,” you can view the current and configured values for the
Radio and Advanced parameters.
Current values are already in use by the Ethernet Adapter.
If the configured value is different from the current value, the
Ethernet Adapter must be reset before the configured value takes
effect and at that time, the configured value becomes the new
current value.
The diagram on the next page shows the software trees associated with the Display Parameter Values menu.

10. Performance Hints
This section provides ideas for how to increase performance with
Proxim wireless products.
Microwave Ovens
Microwave ovens operate in the same frequency band as
RangeLAN2. Therefore, if you use a microwave within range of
RangeLAN2 products, you may notice network performance
degradation. However, both your microwave and your
RangeLAN2 network will continue to function.
Range
Every environment is unique with different obstacles, barriers,
materials, etc. and, therefore, it is difficult to determine the exact
range that will be achieved without testing. Proxim has developed some guidelines to estimate the range that users will see
when the RangeLAN2 7920 Ethernet Adapter is installed in their
facility, but there are no hard and fast specifications. Note that the
RangeLAN2 7921 Ethernet Adapter will have greater range.
Radio signals may reflect off of some obstacles or be absorbed by
others depending on their construction. For example, with two
RangeLAN2 radios you may achieve up to 1000' in open space
outdoors where the two antennas are line of sight, meaning they
see each other with no obstacles. However, the same two units
will only achieve up to 500' of range when they have to travel
through the cubicles usually used in modern offices. If there are
office walls to penetrate, the signal range may decrease even
further to up to 300'.
47
If you are interested in antenna options, contact your Proxim Sales
Representative about antenna kits.
Proper antenna placement can help improve range. Here are
some guidelines:
❑ The antenna should be placed in a vertical position.
❑ Do not place a sheet of metal (like a filing cabinet)
between two antennas.
❑ Two antennas that are communicating should be in the
same plane. For example, do not lie one antenna on its
side and have its partner standing upright.
48
11. Troubleshooting
The RangeLAN2 792x Ethernet Adapter is designed to be very
easy to install and operate. If you do experience difficulties,
however, use the information in this chapter to help diagnose and
solve problems. If you cannot resolve a problem, contact Proxim,
as described in Appendix E, “How to Reach Technical Support.”
How to Obtain Help with
Your Product Installation
If you require assistance to install your Ethernet Adapter, Proxim
can put you in touch with a RangeLAN2 Reseller in your area.
The reseller is an expert in the design, installation, and maintenance of wireless communication products and will be able to
examine your needs and recommend the most cost-effective
wireless solution for you. For the location of the RangeLAN2
reseller nearest you, contact Proxim at 800-229-1630 and ask for
the Sales Department.
Fixed Node Filtering on
RangeLAN2 Access Points
Proxim's RangeLAN2 Access Points are designed to prevent
packets destined for a wired node from being transmitted to the
wireless networks. Each Proxim RangeLAN2 product has a
unique MAC address which begins with 00:20:A6. By default,
packets destined for a MAC address which does not have the
RangeLAN2 prefix are not transmitted to the wireless network by
the Access Point. This process is called Fixed Node Filtering,
Filter Fixed Nodes, or NON-RangeLAN2 Address Filter.
However, an Ethernet-ready device attached to the Ethernet
Adapter will not have a MAC address with the RangeLAN2
49
prefix. Therefore, an Access Point will filter out packets destined
for these devices, and these devices will not be able to communicate through the Access Points with the wired network.
This is not an issue for Ethernet Access Points with revision 1.4
or greater of the flash code image installed. Proxim has modified
the flash code for these Access Points to allow non-RangeLAN2
devices attached to an Ethernet Adapter to communicate with the
wired network without having to disable the Fixed Node Filtering
parameter. Note that in order for the Access Point to pass packets
destined for these non-RangeLAN2 addresses to the wireless
network, it must first learn of their existence. Therefore, each
non-RangeLAN2 device must send a packet through the Access
Point before the Access Point will begin to forward packets to it.
This should not be pose a problem for the majority of networks.
However, if the network contains a Token Ring Access Point or
the earlier mode of the RangeLAN2 Ethernet Access Point
(model 7500), then the Fixed Node Filtering parameter must be
disabled to allow packets destined for non-RangeLAN2 addresses
to be transmitted to the wireless network. Note that transmitting
packets destined for non-RangeLAN2 addresses may cause the
overall wireless performance to decline.
If the Ethernet Adapter has Roaming Enabled, each Access Point
to which the Ethernet Adapter may synchronize must be
reconfigured so that Fixed Node Filtering is disabled. Therefore,
if your Ethernet Adapter will be a stationary device, you should
disable roaming in the Ethernet Adapter's Radio Configuration
Menu so that Fixed Node Filtering will only need to be disabled
on one Access Point on your network.
The procedure for disabling Fixed Node Filtering differs depending on the model of the RangeLAN2 Access Point. Consult your
Access Point manual for additional information.
50
Below is a summary for changing this parameter on each model:
Model 7500: Uncheck the NON-RangeLAN2 Address Filter on
the Filter Configuration page of the 7500's Configuration Tool.
Model 7510/752x: No action is needed if the Access Point has
revision 1.4 or greater of the flash code image installed. If the
Access Point is using an earlier version of the flash code, set the
Filter Fixed Nodes parameter to “Not Filtering” in the Filter
Configuration Menu.
Model 753x, operating in TB or Single-Ring SR/TB mode:
There is no Filter Fixed Nodes parameter when operating the
Token Ring Access Point in these bridging modes. Instead, you
may configure the Access Point to forward packets destined for
up to 3 MAC address prefixes in addition to the RangeLAN2
prefix. These MAC address prefixes may be set in the Hardware
Filtering Configuration Menu.
Model 753x, operating in Multi-Ring SR/TB mode: Set the
Filter Fixed Nodes parameter to "Not Filtering" in the Filter
Configuration Menu.
51
LED Error Codes
The main power LED located on the top of the Ethernet Adapter
will flash red in repeating patterns to indicate the following errors:
1 blink: Could not initialize Ethernet interface
2 blinks: Memory check failed
3 blinks: Software error
4 blinks: Failed to initialize the radio
5 blinks: Memory full
6 blinks: Ethernet interface error
7 blinks: Miscellaneous error
If you see any of the above flashing sequences, first attempt to
reset the Ethernet Adapter. If the flashing sequence persists after
you have reset the unit, make a note of which of the above patterns you have and call Proxim Technical Support.

At some point in the future, you may need to upgrade the RangeLAN2
Ethernet Adapter software. To do this, choose the Download New
Software Version option from the Main Menu. You need to use the
XMODEM protocol to complete the download. Commonly used
serial communication programs, such as Hyperterminal and Procomm
Plus, support the XMODEM protocol.
The steps for downloading a new image are:
1. Place the new software file on the computer's hard drive,
a floppy disk, or a network server.
2. Attach the Ethernet Adapter to a free serial port on the
computer using an RS-232 cable.
3. Open a terminal screen and set the serial port settings to
9600 bps, 8 data bits, 1 stop bit, no parity.
4. Bring up the Ethernet Adapter configuration menu by
typing <Enter> in a terminal screen when the unit is
powered up.
5. Choose Download New Software Version from the
Main Menu.
6. You will be prompted to send a file containing the
software version using the XMODEM protocol.
7. When the download is successful, the Ethernet Adapter
will automatically reboot using the new software.
61
Note:
Do not choose the "Download New Software Version"
menu item unless you are prepared to perform a
software download to the device. Once you proceed
past the warning messages, there is no way to exit the
download process. The unit will not become operational again until after a download of software to the
Ethernet Adapter has been successfully completed.

D. Glossary
10BASE-T Cross-over Cable — A standard 10BASE-T
Ethernet cable with pins 1 & 3 and 2 & 6 crossed to allow two
Ethernet devices with the same pin specification to communicate
directly with one another.
Access Point — An internetworking device that seamlessly
connects wired and wireless networks together.
Bandwidth — The size (in Hertz) of the frequency range that a
signal transmission occupies. Typical narrow band signals occupy a 25 KHz bandwidth. The RangeLAN2 signal occupies a 1
MHz bandwidth.
Channel — In RangeLAN2 networks, the channel refers to the
frequency hopping sequence the card follows.
CSMA/CA — (Carrier Sense Multiple Access/Collision Avoidance) — CSMA is a protocol in which each node senses whether
or not a channel is in use before attempting to transmit information. CA is an optimization by which channel time is reserved to
avoid collisions.
DCE — (Data Communication Equipment) — A device, such as
a modem, which connects to a DTE with a serial cable, that
allows a DTE to send and receive data with remote locations.
DTE — (Data Terminal Equipment) — A device, such as a
computer or dumb terminal, which connects to a DCE from its
serial port in order to send and receive data with remote locations.
Download Image — A software file that is used to upgrade the
software code running on the Ethernet Adapter.
63
Filtering — An action performed by an Ethernet device, such as
a bridge, switch, or router, which excludes an Ethernet packet
from being passed from one subnetwork to another based upon
the packet's destination, source, or packet type.
Frequency Hopping — A spread spectrum technique by which
the band is divided into a number of channels and the transmissions hop from channel to channel in a pre-specified sequence.
Interference — A situation that occurs when an unwanted RF
signal occupies the same frequency band as a desired signal.
IP Address — (Internet protocol address) — A 32-bit address
assigned to TCP/IP hosts.
Narrow Band — A channel of about 25 KHz bandwidth in the
RF spectrum. The FCC allocates Narrow Band channels and
issues a license to the user. Each user of a specific narrow band
frequency range must obtain a site license from the FCC.
Spread Spectrum — A radio data transmission modulation
technique by which the transmitted signal is spread over a bandwidth wider than the information bandwidth. Spread Spectrum
bands are designated by the FCC and require no user license.
TCP/IP — Transmission Control Protocol/Internet Protocol. A
suite of protocols developed under DARPA sponsorship for
internetworking.
