Regulatory Approvals

All components used in the Wireless Internet Service Link are certified to meet the following

specifications:

FCC: Part15, Class B

UL Declaration of Conformity (pending)

FCC Statement

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection

against harmful interference in a residential installation. This equipment generates, uses and can

radiate radio frequency energy and if not installed and used in accordance with the instructions, may

cause harmful interference to radio communications. However, there is no guarantee that interference

will not occur in a particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

- Consult the dealer or an experienced radio/TV technician for help.

This equipment has been certified to comply with the limits for a class B computing device pursuant to

FCC Rules. In order to maintain compliance with FCC regulations, shielded cables must be used

with this equipment. Operation with non-approved equipment or unshielded cables is likely to result

in interference to radio and TV reception. The user is cautioned that changes and modifications

made to the equipment without the approval of the manufacturer could void the user's authority to

operate this equipment.

FCC Maximum Permissible Exposure Guidelines

In 1996, the FCC adopted new guidelines for evaluating environmental effects of RF emissions. The

set limits for Maximum Permissible Exposure (MPE) to RF energy in the 2.4 GHz band, where the

RadioWire Modem operates, is set at 5 mW/cm2 for Occupational/Controlled Exposures and

1 mW/cm2 for General Population/Uncontrolled Exposure. Occupational/Controlled limits apply in

situations where persons are exposed as a consequence of their employment, provided that those

persons are fully aware of the potential for exposure and can exercise control of their exposure.

Uncontrolled Exposure applies to situations where the general public may be exposed and may not

be fully aware of the potential for exposure or can not exercise control over their exposure.

The RadioWire Modem (RWM) should be installed by a competent technical person who understands

the potential for exposure and can exercise proper judgement during the installation of this product.

Radio Connect Corporation (RCC) recommends that the RWM be installed in a location where

members of the general population cannot walk into the direct RF path or touch the antenna. This is

necessary both to ensure a reliable connection and to avoid unnecessary exposure to RF emissions.

Wireless Internet Service Link - User's Manual

DRAFT iii

RCC recommends that the installation of the RadioWire Equipment is done with the equipment off to

eliminate the risk of unnecessary exposure to RF energy. When fine tuning the direction of the

antenna, keep your RF exposure time to a minimum if you need to place hands or other body parts in

locations listed in the special cases below. Normal installation of this product is possible without

exposure to RF levels in excess of MPE limits for Controlled Exposure.

With installation per RCC recommendations, the RadioWire Modem does not generate power density

levels in excess of the MPE Limits for General Population/Uncontrolled Exposure. Be aware of the

situations where the limits for Occupational/Controlled Exposures are approached or exceeded.

These are:

 Maximum Permissible Exposure (MPE) limits for Uncontrolled Exposure is exceeded for

distances closer than 22.4 cm (9 inches) from the helical antenna within the 35o beamwidth.

 MPE limits for Controlled Exposure is exceeded for distances closer than 10 cm (4 inches) from

the helical antenna within the 35o beamwidth.

 MPE limits for Controlled Exposure can be exceeded in the area between the reflecting surface of

both the 0.6m and 1m dish and the actively radiating antenna.

 For the 0.6 meter dish, the MPE limits for Uncontrolled Exposure is exceeded on the reflecting

surface of the dish.

As noted above, RCC recommends that this equipment be installed so these situations are not

generally possible.

2 System Description

2.1 RadioWire 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 service 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:

Figure 2-1. Alignment Indicator LEDs

The indicator lights have the following functions:

Green = Received Signal Level/Acquisition

After signal acquisition, this green LED flashes at a rate proportional to the signal

level. Low signal levels will cause a slow blinking, while higher levels will cause the

blink rate to increase. At very high levels, the LED to appear to be on continuously.

Red = Packet error:

Indicates the occurrence of a link level error. The flash rate matches the rate at

which packet errors occur. Unless link error correction has been disabled, automatic

error correction is performed by the modem.

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 pre-requisite. Note that the upper limit of 20 miles is governed by protocol constraints,

and not by the antenna gain.

Helical 0.6m dish 1.0m dish

Helical Range: 5 miles (8 km)

Link margin: 25.7 dB

0.6m dish Range: 10 miles (16 km)

Link margin: 25.7 dB Range: 20 miles (32 km)

Link margin: 29.7 dB Range: 20 miles (32 km)

Link margin: 33.7 dB

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 fire-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 shafts, while plenum-rated cable is required for

routing through under-floor 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

RWM and NIM. The connector for attachment to the RWM is

molded on to the cable, while the DB-25 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.

2.2 Network Interface Module

The Network Interface Module (NIM) provides the connection point between user equipment

and the WISL system. It may be installed as a stand-alone unit, or pairs of NIM units may

be coupled together side-by-side and mounted in a standard 19" rack. RadioConnect offers

a custom kit for this purpose (part number 250-0001-00). When installed in a rack, the NIM

units occupy 1U height.

2.2.1 Rear Panel Connectors

Figure 2-6. Rear Panel

The NIM rear panel is illustrated in Figure 2-6. The following connectors are present on

both models of the NIM (serial or Ethernet):

 AC Power: Standard IEC male connector.

100-240 VAC (auto-sensing), 47-63 Hz

 RWM port: DB-25 female connector, for attachment of

RWM-to-NIM cable. See Appendix F for

signals and pinouts.

 NIM-to-NIM ports: RJ-H connectors, for synchronization among

multiple co-located NIM units.

For the WISL system with serial interface, there is an additional connector:

 Serial port: DB-25 female, for attachment to user equipment.

See Appendix D for EIA-530 signals and pinouts.

2.2.2 Front Panel Display and Indicators

Figure 2-7. Front Panel

Figure 2-7 shows the NIM front panel layout. The liquid crystal display (LCD) at the right

side of the panel displays ongoing status information, and is updated automatically at

1-second intervals.

At the left side of the panel, six light emitting diodes (LEDs) serve as signal indicators:

 USER An active connection exists between the NIM and the user's

(Green LED) 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 NIM.

 CL For the serial NIM, this LED indicates that the NIM clocking

(Red LED) 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.

 TX This LED is on whenever the user's equipment is transmitting

(Yellow) data to the NIM.

 RX This LED is on whenever the NIM is forwarding the data it has

(Yellow) received from the RWM, to the user's equipment.

 ARQ The ARQ LED flashes at the receiving end of a link when a

(Red) packet error is detected.

 LCK This LED has a dual function. It flashes red while the

(Red/Green) 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-configuration 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

DE-9 connector, to which either a PC-compatible computer or a dumb terminal may be

attached. The cable required is a 9-pin straight-through male-to-female serial cable. A

6-foot 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.

2.2.3 Synchronization Cable

One synchronization cable is provided with each WISL system. This 12" cable is used to

connect two NIM units together via the sync ports (RJ-H connectors) on the rear panel. More

than two NIMs may be interconnected by daisy-chaining them together, as shown in

Figure 2-8. Note that the two connectors on each unit are functionally identical, so that

either cable may be plugged into either socket.

Figure 2-8. NIM Units 'Daisy-Chained' for Synchronization

The purpose of interconnecting units in this way is to provide a clock signal between them

that causes all units to synchronize their transmit and receive cycles. The clock signal is

provided by a single NIM configured as the 'primary' unit. The effect of this interconnection

is that all units transmit in the same cycle, and then receive in the same cycle, which avoids

the possibility of some of the co-located units receiving the transmissions of others.

3 Installation

3.1 System Installation Kit

RadioConnect offers 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-foot Console cable

 RF emulation cable

 Cable pull grip

 Cable assembly/continuity tester for RWM-to-NIM cable (comprises 2 components

– loop-back terminator for RWM end of cable, and display terminator for NIM end.)

 Tools: Allen key, screwdriver and wrench

 Magnetic compass

In addition to these items, the person installing the link may also need a steel-tape cable

puller (also referred to as a "snake"), and some nylon cable ties. A cable tie will be used to

attach the cable pull grip to the cable puller, as explained in Section 3.6.1 below.

3.2 Installation Procedure

Figure 3-1 shows a high level flowchart of the required and optional steps for installing a

link. The WISL equipment can be installed without requiring initial configuration. However,

this is not recommended, as it is much easier to configure and test both units together at a

single location, before they are transferred to their eventual (remote) sites.

In either case, at least one configuration parameter must be set before the two WISL

systems can communicate. That parameter is the ‘Master/Slave Status’ (Section 3.4.3). Until

one end of the link is set as Master, and the other end as Slave, installed units cannot be

aligned.

CAUTION

If you are not familiar with working on towers and antennas,

get help from an experienced installer. Installing tower

structures and mounting antennas can be dangerous and

life threatening. Make sure the tower or pole you are using

is of appropriate size to carry the weight and wind load of

the RadioWire Modem and antenna system.

3.3 Configuring Your System

The first step towards configuring each of your WISL systems is to complete the link

Configuration Worksheet (Appendix C). Refer to the System Overview and Planning Manual

(part number 950-0001-00) for guidance in preparing the Worksheet. There are several

important parameters that must be configured correctly for proper operation:

1) Pseudo-random spreading code

2) Frequency channel

3) Master/Slave status

4) Synchronization generator status

5) Transmit power control mode and level

Each of these parameters is discussed in detail below, and a completed Worksheet example

is shown in Figure 3-8.

Next, take the following steps in preparation for configuring each unit:

 If the configuration process is being carried out before a WISL system has been

installed, connect the RWM and NIM together using the 3-foot cable provided in the

System Installation Kit.

3.4 Radio Configuration Parameters

3.4.1 Frequency Channel

The RadioWire Modem supports three discrete, non-overlapping frequency channels within

the 2.4 GHz band allocated for unlicensed use. 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-locating more than

three RWM units at the same site. Select the desired channel from the pull-down menu.

3.4.2 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-located, they will typically all be specified as Masters

(Figure 3-5). However, if a hierarchical network is being built, similar to that shown in

Figure 3-6, 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). Click on the appropriate button to select

Master or Slave status.

Wireless Internet Service Link - User's Manual Section 4: Operation

3-6 DRAFT

Figure 3-6. Master/Slave Assignments in a Hierarchical Network

3.4.3 Synchronization Generator

When multiple RWMs are co-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-located units must receive the synchronization signal through the

‘daisy-chain’ of cables that couple their NIMs together.

A special requirement applies at all subsidiary nodes of a hierarchical network. At all such

nodes, only Slave units may take the role of synchronization generators. This is because a

Slave unit derives its clock from the airwave signal it receives from its associated Master.

This requirement ensures that the entire network operates coherently from a single clock

source. The example in Figure 3-7 illustrates this. Click on Sync Generator, if required.

3.4.4 Transmit Power Level

The transmit power level may be set between a minimum of -2dB and a maximum of +24dB.

When shipped, the default setting is 0dB. If a unit is being configured prior to installation,

care should be taken with regard to increasing the power level. Excessive power levels can

be hazardous to humans, as well as to other operating radio equipment in the near vicinity.

If possible, setting of the power level should be left until the link is being installed. In the

U.S.A., the maximum power level of +24dB is only required when operating at the maximum

range specified for the antennas. Some countries require a lower maximum transmit power

level than the +24dB permitted in the U.S.A.

3.4.5 Pseudo-Random Spreading Code

There are more than 16,000 possible pseudo-random spreading codes available to ensure

the privacy of RadioWire links, and which contribute towards the extraordinary interference

rejection characteristics of RWM 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.

3.5 NIM Configuration Parameters

By default, this field will display the type of NIM being configured - Serial or Ethernet - and

3.5.2 Clock Polarity (Serial only)

This parameter must match the clock polarity of the equipment attached to the NIM. The

default setting is 'Normal'. If necessary, click on 'Inverted'.

3.5.3 User Mode (Serial only)

The connector on the Serial NIM for attachment of user equipment is a female DB-25.

However, the User Mode parameter allows you to select the active signal interface on the

connector. The choices available on the pull-down menu are V.35, EIA-530, EIA-530A or

3.6 Pre-Installation 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.

The procedure for pre-installation testing is as follows:

1) After 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 RWM 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 3.5.1)

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. If not, refer to ‘Troubleshooting’ (Section 3.5.1) below.

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 satisfactorily at any

distance less than 1.3 kilometers.

3.7 Installing the RadioWire Modem

This procedure assumes that suitable locations have been selected for installation of the

equipment at both ends of the link, and that poles or towers are available on which to mount

the RadioWire Modems. It also assumes that during the pre-installation survey, a suitable

route was determined for running the serial cable down from the RWM to the NIM, at each

end of the link.

Take the following items up to the roof area where the RWM is to be installed:

 RadioWire Modem

 Antenna and its assembly fasteners

 Mounting bracket and assembly fasteners

Also, the following items from the System Installation kit (or suitable equivalents):

 Cable pull grip

 Loop-back terminator for RWM end of cable (a component of the cable

assembly/continuity tester for the RWM-to-NIM cable)

 Allen key, screwdriver and wrench

 Compass

3.7.1 Attaching the RWM and Antenna to the Pole

With all the necessary equipment gathered at the mounting site, the next step is to install the

mounting bracket assembly. Figure 3-9 shows how this is done. Position the bracket so

that it is facing approximately in the direction of the remote site, and is at the desired height

on the pole. Use the compass provided in the System Installation kit to set the azimuth, if

the remote location is too distant to be seen with the naked eye. Note that the azimuth

values of one site with respect to the other were entered on the Configuration Worksheet

during the link-planning phase. Tighten the mounting bolts enough to allow the bracket to

bear the weight of the modem and antenna.

The next activity depends on which antenna you are using. In the case of the 1-meter

antenna, it must first be assembled. Attach the 3 legs to the main dish, using the bolts,

washers and nuts provided, and then attach the modem-mounting plate to the legs (see

Figure 3-10). The other two antennas do not require assembly.

Now attach the RadioWire Modem to the antenna, using the four knurled Allen screws

provided. Refer to Figures 2-3 through 2-5 for the way in which the two parts fit together.

CAUTION

For compliance with safety regulations, the

RadioWire Modem must be grounded to

earth. It is recommended that a metal pole

be used for mounting the RWM, and that

the pole itself has a substantial connection

to an earth grounding system.

Wireless Internet Service Link - User's Manual Section 4: Operation

3-12 DRAFT

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 ***).

For the two smaller antennas, it is the RWM that attaches to the mounting bracket. On the

rear of the RWM enclosure, there is a metal strip that serves 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 RWM (Figure 3-9). This hook-and-lip 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 RWM units at the two ends of the link. But for the moment, the next step is to

install the cable from the roof 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 end is being

pulled down.

3.7.2 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 3-11). Similarly, if a clear vertical path is available within the wall cavity, the cable

can be installed without the need for a puller.

However, cable routing is typically not as straightforward 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 roof, and slide the cable pull grip fully over the open end of the cable,

ensuring that no slippage occurs once the grip is in place (Figure 3-12). 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 DB-25 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 off.

Separate the two halves of the DB-25

connector shell and remove the main body

(see Figure 3-13). 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 full contact with the

shell halves at the cable-entry collar. Insert

and tighten the screw that holds the two

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.

(**** Add tester operating procedure ****)

After removing the test terminators, reconnect

the cable to the RWM.

3.8 Installing the Network Interface Module

The Network Interface Module must be located in the vicinity of the user equipment to which

it will be connected. It may either be installed as a freestanding unit on a suitable surface

such as a shelf, or a pair of NIM units may be attached side-by-side and rack-mounted in a

standard 19" rack. A special RadioConnect Universal Rack-Mount kit (Figure 3-14) is

available from your reseller for this purpose (part number 250-0001-00).

If multiple WISL systems are being installed at the same location, they must be inter-

connected using the synchronization cables provided. Refer to Section 2.2.3 for details of

how to "daisy-chain" multiple NIM units together.

After physically installing the NIM unit(s), connect the cable from the RWM, to the

appropriate DB-25 socket on the rear panel.

3.8.1 Electrical Requirements

The system is now ready to be powered up. Connect the power cord to the NIM. For

compliance with safety regulations, the NIM must be connected to a properly grounded

electrical circuit.

The foregoing procedure for mounting the RadioWire Modem and antenna, installing the

RWM-to-NIM cable, and installing the Network Interface Module, must next be repeated for

the WISL system at the other end of the link. Once this has been done, you are ready to

proceed with alignment of the systems.

3.9 Antenna Alignment Procedure

With power applied to both WISL systems, return again to the roof at one end of the link.

Inspect the LEDs on the underside of the RadioWire Modem. If the green LED is on solidly,

and the red LED is off (i.e. not flashing), no further adjustment is needed. Simply tighten all

bolts and fasteners as much as possible, using the tools provided.

If the status of the LEDs is not as required, carefully loosen the mounting bracket bolts just

enough to be able to rotate the Modem around the pole. Be sure that while you do this, you

support the unit so that it does not slide down the pole. Next, adjust the azimuth in small

increments to the left or right, until the optimum LED status is achieved. If it is not possible

to find an ideal position at which the green LED is on solidly and the red LED is fully off, then

the best position is that at which the flashing of the red LED is minimized. Once this is

accomplished, tighten the mounting bracket bolts as much as possible.

You may also try optimizing the LED status by adjusting the elevation angle of the RWM.

Do this by loosening the vertical tilt bolts on the mounting bracket, then tilting the unit up or

down in small increments.

Once the best possible combination of red and green LED status is achieved, tighten all

bolts and fasteners as much as possible.

Repeat this alignment procedure at the other end of the link.

3.10 Connecting to User’s Equipment

The final step in installing your Wireless Internet Service Link is to connect the NIM at each

end of the link to its associated user equipment. (*** More information to be added ***)

APPENDIX F RWM-To-NIM Cable Specification

The RadioWire RF Modem uses a square-flange AMP Series 2 Circular Plastic Connector

receptacle P/N 205840-3 on the housing. The RWM-to-NIM cable mates to the RWM using

an AMP P/N 205839-3. The other end of the cable mates to the NIM using a DB-25

connector - male on the cable, female on the NIM rear panel.

The following table shows the signals and cable pin-outs:
