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

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.
