2 System Description
2.1 Radio Wire Modem
The RadioWire Modem is housed in a cast aluminum casing designed to withstand severe
weather conditions. It contains no parts that require user access, and should not be opened
by anyone except RadioConnect‘s authorized serwce personnel,
2.1.1 Alignment Indicators
Two alignment indicators are inset into the underside of the RWM case for ease of viewing
from a distance and in bright sunlight. These indicators are light emitting diodes (LEDs) -
one green, and one red:
Green
Figure 2-1. Alignment Indicator LEDs
The indicator lights have the lollowing functions:
Green = Signal Quality/Power:
Flashes at 0.5 Hz rate, 25% duty cycle, when power is present but no correlation.
Flashes at 2 Hz rate. 25% duty cycle, when signal is detected.
Duty cycle (‘on' state) increases as signal quality improves. Duty cycle reaches
100% (ie. the LED is on continuously) when the received signal achieves a 20 dB
margin level above the tO'E BER receiver sensitivity level.
Red = Packet error:
Indicates the occurrence of a link level error.
Duty cycle varies from 0% to 100% depending on retransmission rate.

2.1.2 Antenna
Figures 2-3 through 2—5 provide details of the three antenna types available with the RWM.
It is not necessary to use the same type of antenna at the two ends of a link. The actual
combination depends on the range required. Table 2-1 shows the range capabilities of each
possible combination in free space conditions, assuming that a link margin of at least 25 dB
is ore-requisite. Note that the upper limit of 20 miles is governed by protocol constraints,
and not by the antenna gain.

Table 2-1. Range and Link Margin with Different Antenna Combinations
2.1.3 Mounting Bracket
RadioConnect antenna mounting brackets are designed to allow tilting in the vertical plane,
to accommodate elevation differences between the RWM units at the two ends of a link.
This capability is especially useful for relatively short links. The brackets are calibrated with
tilt angles above and below horizontal. Once the RadioWire Modems have been installed
and aligned with each other, and the brackets firmly locked in their optimum positions, you
should record the tilt angles read from the mounting brackets, in your Configuration
Worksheet.
2.1.4 RWM-to-NIM Cable
The cable that runs between the roof-mounted RWM and the
in-building NIM is a special serial cable that carries low
voltage power up to the RWM, as well as carrying data
between the units. This cable is offered in standard lengths
from 25 feet to 200 feet, and in two different tire-resistance
ratings - standard or plenum-rated. Custom lengths are also
available to special order. Check that the lengths of the
cables you receive match your order, and if there is any
discrepancy, notify your reseller as soon as possible.
The standard PVC cable is satisfactory for use in vertical wall
cavities and shalts, while plenum—rated cable is required for
routing through underfloor plenum space. in either case, the
cable is supplied as a kit, with the connector not installed at
one end in order to facilitate feeding the cable between the
HWM and NIM. The connector for attachment to the RWM is
molded on to the cable, while the 0325 for attachment to the
NIM is not installed. Instead, the open end of the cable has a
sleeve on it, as shown in Figure 2—2.

Figure 2-7 shows the MM iront panel layout. The liquid crystal display (LCD) at the right
side of the panel displays ongoing status information, as selected by the user during setup.
The status information is updated automatically at (BO—second intervals.
At the left side of the panel, six light emitting diodes (LEDs) serve as signal indicators:

An active connection exists between the MM and the user‘s
equipment. For the serial NIM, this implies that the cable
between the NIM and the user‘s equipment is installed, and
that the DTR (Data Terminal Ready) signal is asserted. For
the Ethernet NIM, the LED indicates that an active Ethernet
cable is connected to the MM.
For the serial NIM, this LED indicates that the NIM clocking
signal is present. This is the signal that enables synchronous
transmission to occur. For the Ethernet NIM, this LED flashes
whenever a collision is detected.
This LED is on whenever the user's equipment is transmitting
data to the NIM.
This LED is on whenever the NIM is forwarding the data it has
received from the RWM, to the user's equipment.
The ARQ LED flashes at the receiving end of a link when a
packet error is detected.
This LED has a dual function. It flashes red while the
RadioWire modems at the two ends of the link are attempting
to synchronize with one another. Once synchronized, the LED
changes to a solid green display, indicating that the two ends
are locked.
For initial configuration or re-coniiguration of the WISL system, the front panel of the NIM
unit may be removed to provide access to the Console port. The port comprises a female
059 connector, to which either a PC-compatible computer or a dumb terminal may be
attached. The cable required is a 9»pin straight-through maie~to—female serial cable. A
G-loot cable of this type is included in the System Installation Kit available separately from
RadioConnect (part number 004-0001-00). Such cables are also readily available at most
computer stores.

CAUTION
If you are not familiar with working on towers and antennas,
get help from an experienced installer. Installing tower
structures and mounting antennae can be dangerous and
lite threatening. Make sure the tower or pole you are using
is of appropriate size to carry the weight and wind load of
the RadioWIre Modern and antenna system.
3.1 System Installation Kit
FtadioConnect otters a System Installation Kit (part number 004-0001-00) which may be
purchased separately from your WISL systems. Although not pre-requisite for installing a
link, the kit is recommended. It is re-usable for installing multiple links, and contains the
following items: '
- 3-foot RWM-to-NIM cable, required if units are to be configured prior to installation
- 6-fool Console cable
- RF emulation cable
- Cable pull grip
- Cable assembly/continuity tester for FlWM key (.J}, and you should
see the messages:

3.4.1 Pseudo-Random Spreading Code
There are more than 16,000 possible pseudorandom spreading codes available to ensure
the privacy of FladioWire links, and which contribute towards the extraordinary interference
rejection characteristics of FtWM units. The same value must be configured for both ends of
a link. If multiple links are to be installed, select a different code for each link.
Many RWMs can share the same frequency channel with negligible interference when a
different pseudo-random code is selected for each different link.
Command format.“ PCnJ
Where n = 0 - 16,383 (default = 0)
3.4.2 Frequency Channel
The RadioWire Modern supports three discrete, non-overlapping frequency channels within
the 2.4 GHz band allocated for unlicensed use in the U.S.A. These are shown in the
Configuration Worksheet as channels 1, 3 and 5. The other two channels (2 and 4) partially
overlap their neighbors. In general, use channels 1, 3 or 5 only, unless you are co-Iocatlng
more than three RWM units at the same site.
Command format: CHnJ
Where n = 1 - 5 (default: 1)
3.4.3 Master/Slave Status
One unit on each point-to-point link must be configured as the link Master. The other unit
must be the link Slave. The link Master controls transmit and receive timing for a given link
When multiple RWM units are co-Iocated, they will typically all be specified as Masters
(Figure 3-2). However, if a hierarchical network is being bum, similar to that shown in
Figure 3-3, all nodes except the central one will have at least one Slave coupled to one or
more subsidiary Masters through appropriate user equipment such as an Ethernet hub or a
serial synchronous time-division multiplexer (TDM).
Command format: MAJ (Master) (default)
SLJ (Slave)

Wireless Internet Service Link - User's Manual Sectlan 3: lnstallatlon
FCC to: NF'X-RCCllOOl-OO ‘
3.4.4 Synchronization Generator Status
When multiple HWMs are oo-located at a site, they must be synchronized to all transmit at
the same time and all receive at the same time, to help avoid mutual interference. To
accomplish this, every RWM is equipped with the ability to generate a synchronous clock
signal. However, only one unit can be the active synchronization generator at any given
time, and all other co—Iocated units must receive the synchronization signal through the
‘daisy-chain‘ of cables that couple their NlMs together. The FlWM that will be the active
synchronization generator must be specified as the ‘Primary’, in the Configuration
Worksheet.
In the event of failure ol the primary unit, another FlWM may be designated to take over the
role of synchronization generator. This unit is specified as the ‘Secondary’. Similarly, in the
event of failure of the Secondary unit, a third unit may be designated to take over. It is
specified in the Worksheet as the ‘Tertiary‘, This is illustrated in Figure 3-4. Note that
designation of Secondary and Tertiaw synchronization generators are recommended, but
not ore-requisite.
A special requirement applies at all subsidiary nodes of a hierarchical network. At all such
nodes, o_nlv Slave units may take the role of synchronization generators. This is because a
Slave unit derives its clock from the airwave signal it receives lrom its associated Master. In
the example shown in Figure 3-5, two links from the central node (using different frequency
channels) feed a subsidiary node, and several downlinks emanate from the latter. The two
Slaves at the subsidiary node are designated as Primary and Secondary, while the
subsidiary Masters must all be configured with their synchronization generator parameters
set to ‘None’.

3.4.5 Transmit Power Control Mode and Level
This parameter may be set to either ‘Auto’ or ‘Manual’ mode. Under most circumstances,
Auto mode should be specified. However, some countries require a lower transmit power
level than the +24dB permitted in the USA. In such cases, specify Manual mode and set
the appropriate power level.

3.5 Pre-Insfallation Testing
To ensure satisfactory operation between two WISL systems, they may be tested together
before being transferred to their eventual destinations. For testing in close proximity, the RF
emulation cable supplied in the System Installation kit must be used.
CAUTION
Do not under any circumstances attempt to test two
RadioWire Modems in close proximity, with their
antennas installed. To do so may result in severe
damage to both units, due to excessive signal load
on the receivers.
- Two units equipped with +14dBi helical
antennas may not work satisfactorily at any
distance less than 130 meters.
Two units equipped with +24dBi helical
antennas may not work satlsfactorily at any
distance less than 1.3 kilometers.
The procedure for pre-lnstallation testing is as follows:
1) Alter configuring each of the two WISL systems, disconnect power to both of them.
2) Carefully remove each RWM from its antenna using the Allen key supplied in the System
Installation kit. Set aside the antennas for later re-attachment.
3) Place the two RWM units on a flat surface about 2-3 feet apart, with their antenna
sockets uppermost. Connect the RF emulation cable between the two sockets.
4) Connect each RWM to its NIM (if not already connected), using the 3-foot cables
supplied in the System Installation kit.
5) Power up both systems. Within about 20 seconds, the green LED on each FIWM should
turn on solidly and the red LED should be off. In addition, the ‘Lock’ (LCK) indicator on
the NIM front panels should both be on (green), and the ‘Error’ (ARQ) indicator should
be off. If this is the situation, the two WISL systems are communicating satisfactorily,
and you can move on to step 6). Otherwise, refer to ‘Troubleshooting’ (Section 3.51)
below.
6) This step is optional. If you have the necessary equipment available for transferring user
data across the link, make the necessary connections to the two NIMs, and ensure that
data transfer is working correctly. It not, refer to ‘Troubleshooting‘ (Section 3.51) below.

Attach the combined RWM/antenna assembly to the mounting bracket on the pole. Once
again, the method of attachment for the 1-meter antenna is different than for the other two
antennas. ("' 1-meter antenna TBD m).
For the two smallerantennas, it is the RWM that attaches to the mounting bracket. On the
rear of the FtWM enclosure, there is a metal strip that sen/es as a hook. It allows the RWM
to be hung on the mounting bracket in the correct position for the large knurled fasteners to
be screwed into the FtWM (Figure 3-7). This hook-and-Iip system makes it possible to
complete attachment of the RWM/antenna assembly using only a single hand, which may
be necessary in situations where you need to use your second hand for support.
Later on, elevation and azimuth adjustments will be made via the mounting bracket, in order
to align the FlWM units at the two ends of the link. But for the moment, the next step is to
install the cable from the root down to the NIM location. Begin by securely connecting the
cable to the RWM. This will anchor the upper end of the cable while the other and is being
pulled down.

3.6.2 Cable Installation
At this point, you must determine whether a cable puller tool will be needed. For example, if
the cable will be run external to the building walls, the tool will probably not be needed
(Figure 3-9). Similarly, if a clear vertical path is available within the wall cavity, the cable can
be installed without the need tor a puller.

Figure 3-9. Internal and External Cable Routing
However, cable routing is typically not as straighttorward as shown here. Often, obstacles
within the wall cavities must be circumvented, or the cable must travel through a
combination of wall and floor cavities. In these cases, use a cable puller, starting from the
NIM location and working the steel tape up to the roof.
Next, return to the root, and slide the cable pull grip tully over the open end of the cable,
ensuring that no slippage occurs once the grip is in place (Figure 3-10). Now connect the
loops at the ends of the cable pull grip and the steel tape, using a nylon tie wrap threaded
through them both. Trim the free end of the tie wrap, so that it will not catch on anything as
it passes through wall and/or floor cavities.
Return to the NIM location, and proceed to carefully reel-in the steel tape until the cable
reaches you. During this procedure, it may be useful or necessary to have the assistance of
a second person on the roof to feed the cable, ensuring that it does not get tangled.
You are now ready to install the D825 connector on the NIM end of the cable. Remove the
cable pull grip from the cable end, by pushing it off from its open end. This compresses the
mesh, thus releasing its friction grip on the cable and allowing it to slide of].

Separate the two halves of the DB-25
connector shell and remove the main body
(see Figure 3-11). Using the pin-out
information provided in Appendix F,
carefully insert the pins into the numbered
holes, from the rear of the main body.
Ensure that all pins are fully seated and
protrude from the connector an equal
amount. Clamp the two shell halves back
over the cable and main body assembly,
ensuring that the braided grounding sheath
of the cable makes lull contact with the
shell halves at the cable-entry collar. Insert
and tighten the screw that holds the two Figure 3.1 0, Cable pun Grip
halves together.
At this point you may optionally test the
complete cable for correct assembly and lead
continuity, using the tester provided in the
System Installation kit. To do so, go up to the
roof, disconnect the cable from the RWM, and
install the loop-back terminator on the cable
connector. Return to the NIM location and
install the display terminator component of the
tester.
