Operational Safety Notes

FCC Notice, U.S.A.

All HopNet products comply with Part 15 of the FCC Rules. Operation is subject to

the following conditions:

•This device may not cause harmful interference, and this device must accept any

interference received, including interference that may cause undesired operation.

•This device is specifically designed to be used under Section 15.203 of the FCC

Rules and Regulations. Any unauthorized modifications or changes to this device

may void the user’s authority to operate.

•This device is intended to be used only when professionally installed. Failure to

comply with these instructions may also void the user’s authority to operate this

device.

European Community Notice

This device complies with ETS 300.328 of the European Community. Operation is

subject to the following conditions:

•This device may not cause interference.

•This device must accept interference, including undesired interference that may

impede the operation of this device.

RF Exposure

WARNING: End Users of these systems must be informed that RF exposure limits

may be exceeded if personnel come closer than 45 cm to the antenna aperture when

exceeding 9 dBi of gain in conjunction with the transceiver.

Repairs

Cirronet does not recommend field repairs of the radio equipment. Surface Mount

Technology (SMT) has been used in the production of the transceiver module, which

requires specialized training and equipment for proper servicing. The equipment

should be returned to the factory for any repair.

HopNet Family of Products

Overview

Introduction

The HopNet 10 Series family of products provides reliable wireless connectivity for

either point-to-point or point-to-multipoint applications. The HopNet products are

built around the WIT2410 radio transceiver, which employs frequency hopping

spread spectrum technology. This technology ensures:

•Maximum resistance to noise

•Maximum resistance to multipath fading

•Robustness in the presence of interfering signals

HopNet Products

The HopNet family of products is built with rugged enclosures compliant with IP 66

and NEMA 4X standards for outdoor and harsh industrial environments. All

Hopnet products work with each other and can be mixed and matched in a single

network. All HopNet Products are WIT2410 compatible and can be used with the

WIT2410 OEM based products as well as with the SNAP2410 10Base T access point.

The HopNet family consists of the following products:

External Antenna

HN-210X Base/Remote Unit

HN-510 Indoor Base/Remote Station

HN-1010 Outdoor Base/Remote Station

HN-1510 Indoor Base/Remote Station

HN-2010 Repeater

Built-In Antenna

HN-210 Base/Remote Unit

HN-3010 Base/Remote Unit

Adapter

Power Supplies

OVERVIEW

HopNet Family of Products 800281Rev. B

Design Features

The HopNet modems have many advanced features:

•Employ frequency hopping technology with up to 75 channels in the 2401 to 2475

MHz frequency range

•Support RS-232 and RS 485 interfaces (HN-210 and HN-510 are RS-232 only)

•Support digital addressing for up to 64 networks, with 62 remotes per network.

•Use transparent ARQ protocol

•Use same hardware for all supported data rates

•Supports up to 230 Kbps asynchronous data rates

•Full Duplex

•Stores setup configuration in nonvolatile memory (FLASH)

•Provide fast acquisition – less than 2 seconds is the typical time to acquire hopping

pattern

•Use smart power management features

Glossary of Terms

Refer to the following list of terms that may be unfamiliar to you. These terms are

used throughout this document.

Term Definition

ARQ Automatic Repeat Request. The operation in which the radio

will re-send the data until it is received correctly.

bps Bits-per-second. A measure of information transfer rate of

digital data across a channel.

Decibel A measure of the ratio between two signal levels. Used to

express either loss or gain.

dBi Decibels referenced to an ideal isotropic radiator in free space.

Used to express antenna gain.

dBm Decibels referenced to 1 milliwatt. An absolute unit used to

measure signal power. Transmitter power output or received

signal strength.

DCE Data Communications Equipment. A device that receives data

in the form of digital signals at its input. The modem side of a

computer-to-modem connection.

DCD Data Carrier Detect.
