Note: This unit 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 his own
expense. Commensurate with EIRP limits specified
in FCC Rules 15.247b, this device may not be used
with antennas that exceed 36dB of gain in point-to­point applications or 16dB of gain in multi-point
applications.

Configuring the Network

Introduction

The HopNet 10 Series family of products provides reliable wireless connectivity for
point-to-point applications. HopNet products employ frequency hopping spread
spectrum technology. This technology ensures:

• Maximum resistance to noise

• Maximum resistance to multipath fading

• Robustness in the presence of interfering signals

The HN-110 is NEMA 4X weatherproof versions of the HopNet product line. The
interface to the 110 allows the Host to communicate with the Remote unit through an
integrated 6 ft (2 meter) cable. The HN-110 can act as either a base or remote.

The HN-110 Remote has an internally mounted 6 dBi patch antenna. The built-in
antenna of the HN-110 case greatly eases outdoor installation since no antenna
feedline cable or adapters are needed. The 6 dBi antenna gain increases the radiated
EIRP to +20 dBm and the effective receiver sensitivity to –86 dBm.

HopNet Benefits

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.

Operating Frequency

The HopNet family operates in the 2.4 GHz ISM band that allows for license-free use
and worldwide compliance.

HopNet Frequency Hopping Spread Spectrum Advantages

In the frequency domain, a multipath fade can be described as a frequency selective
notch that shifts in location and depth over time. Multipath fades typically occupy
five percent of the band. A conventional radio system typically has a five percent
chance of signal impairment at any given time due to multipath fading.

Frequency Hopping Spread Spectrum reduces the vulnerability of a radio system to
both interference from jammers and multipath fading by distributing or spreading the
signal over a larger region of the frequency band.

The fade resistant, HopNet frequency-hopping technology employs up to 79 channels
and switches channels over 1600 times a second to achieve high reliability
throughput.

HopNet Data Integrity

An on-board 3 KB buffer and error correcting over-the-air protocol ensure data
integrity even in the presence of weak signals or jammers. The serial interface
handles both data and control of asynchronous data rates of up to 115 Kbps.

Configuring the Network

Flexible Power Management

You can place the transceiver module in a power-save mode, which enables smart
power management. Smart power management allows a remote unit to drop into a
lower current standby mode during transmission or receiving gaps.

This feature also allows Hopnet products to be used in various countries where the
output power requirements may vary due to regulation.

Advanced Features

HopNet modems have many advanced features:

• Employ frequency hopping technology with up to 79 channels in the 2402 to

2480 MHz frequency range

• Support RS-232 interface

• Use transparent ARQ protocol

• Use same hardware for all supported data rates

• Supports up to 115 Kbps asynchronous data rates

• Full Duplex operation

• Store setup configuration in nonvolatile memory (FLASH)

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

pattern

• Smart power management features

The HopNet Family of Products

The HopNet family consists of the following products:

Configuring the Network

Getting Started

A pair of HN-110s is set up by performing the following steps:

• Install the HopNet Wizard configuration program on a PC

• Connect the HN-110 to the PC

• Run a communications test

These steps are described in detail below. Other steps you may want to perform
include:

• Change the baud rate

Refer to the Configuring the Network section of this manual for details on these steps.

Install the HopNet Configuration Wizard on a PC.

The HopNet Configuration Wizard is located on the software and documentation CD
included in the HN-110 package. Install the program by inserting the CD in the PC
and following the installation wizard. If autorun has been turned off, double-click on
setup.exe on the CD to start the wizard.

Connect the HN-110 to the PC.

Connect the serial adapter box to a serial port on the PC using the serial cable
provided.

Connect one end of the
serial cable to a serial
port on the PC.
