FCC COMPLIANCE STATEMENT

Note: This equipment has been tested and found to comply with the limits for a

Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are

designed to provide reasonable protection against harmful interference when the

equipment is operated in a commercial environment. This equipment generates,

uses, and can radiate radio frequency energy and, if not installed and used in

accordance with the instruction manual, may cause harmful interference to radio

communications. Operation of this equipment in a residential area is likely to

cause harmful interference in which case the user will be required to correct the

interference at the user’s expense.

WARNING

RF EXPOSURE HAZARD

Under certain operational circumstances and when connected to a typical high

gain directional antenna, this equipment is capable of producing RF radiation

exposure in excess of the limits defined in FCC 47CFR 1.1310, Table 1.

Personnel working in the vicinity of an energized antenna should ensure that they

maintain a distance of at least 4.2 feet (1.28 meters) from the antenna in the

direction of maximum gain. All antenna maintenance activities should be

performed only when the associated RF Modem transmit power has been muted.

2 Installation and Configuration

2.1 General Installation and Operating Considerations

2.1.1 Antenna

Avoid operating the transmitter without a proper termination on the RF connector. Although the modem is

designed to withstand such operation, undesired interference to other RF systems may occur.

A typical installation will require the use of a high gain antenna. Proper alignment of the antenna is critical to

ensuring an error-free link. During the alignment process, an

rsl

command from the Craft Interface Terminal

(CIT) will display near real-time receive signal strength and may be used to “peak” the antenna positioning.

This equipment produces RF radiation when connected to a typical high gain directional antenna. Personnel

working in the vicinity of an energized antenna should ensure that they maintain a distance of at least 4.2 feet

(1.28 meters) from the antenna in the direction of maximum gain. See the caution statement at the beginning of

the manual.

The RF Modem is shipped with the transmitter set in the “mute” condition. This is done to prevent inadvertent

transmission on an unauthorized frequency. All operating parameters, including an estimate of the minimum

necessary transmit power, should be programmed into the modem before un-muting the transmitter.

Do not exceed +10 dBm input power at the antenna terminal of the RF Modem or damage to the unit may result.

2.1.2 Site Planning

As with any wireless link, proper system and path planning is essential to ensuring error-free operation. Such

planning should take into consideration path clearances from obstructions, interference from nearby radiators,

multi-path reflections and fading. A system signal strength margin of at least 20 dB above the rated receiver

threshold is standard practice.

When installing multiple modems in the same general location, ensure that they are all transmitting within the

same sub-band to prevent interference and desensitization.

2.1.3 Cooling

Install the RF Modem so that adequate airflow can be maintained through the rear and side vents. If airflow is

restricted, the modem internal temperature may rise above the preset thermal shutdown temperature.

2.1.4 Shielding and Grounding

When the DB-25F connector is used for the RF Modem EIA-530/232 data I/O, ensure that a good quality shielded

cable is used and that the cable shield is electrically terminated to the cable connector shells.

A grounding stud is provided on the rear panel. A ground braid should be attached to this lug and connected to a

local earth ground to prevent static charge build-up on the modem, antenna and associated cabling.

2.2 Configuration Procedure

2.2.1 Password Setup

As shipped from the factory, the default passwords are trivial and not secure. It is strongly suggested that the

passwords be changed before the system is deployed.

5 GHz RF Modem 07-Feb-2006 10 of 73

To change passwords, log in to the system as the administrator by typing the default administrator password

“admin” at the password prompt.

2.2.1.1 Operator Password

The operator password allows the operator to configure and test the data port. Configuration settings for the radio

and the network may be displayed but not changed.

The initial operator password is “oper”. The operator or the administrator may change it using the password

command:

passwd oper

2.2.1.2 Administrator Password

The administrator password allows the administrator to configure all of the modem including the data port, radio

and network.

The initial administrator password is “admin”. The administrator may change it using the password command:

> passwd admin

The administrator may also change the operator password (and the spare password).

2.2.1.3 Spare Password

The spare password is equivalent to the administrator. It is intended as an extra password that may be used in the

event that the administrator password is lost.

The initial spare password is “spare”. The administrator may change it using the password command:

passwd spare

2.2.1.4 Privileged Password

The privileged password is intended for use by a service technician. It allows access to all the operator and

administrative commands plus commands for updating the software and examining various factory-set

parameters.

The initial privileged password is “Volpe.DOT.”. The privileged user may change the password using the

command:

password wheel

The privileged user may also change the operator, administrator, and spare passwords as shown above.

2.2.2 Radio Configuration

A configuration summary with all of the important configuration settings for the radio and the data interface may

be displayed with the

config

command.

2.2.2.1 Dash Setting

The modems come in two configurations known as “dash one” and “dash two.” The “dash one” modems transmit

at a lower frequency than they receive while the “dash two” modems are the reverse. One modem of each type is

required to form a link.
