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 their 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-to-point applications or 16dB of gain in multi-point applications.

Overview

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:

About HopNet Products

About HopNet Products

Introduction

This section provides operational information about the HopNet products.

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 75 channels
and switches channels over 100 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 230 Kbps.

Flexible Power Management

You can set the transmit power at 10 milliwatts or 100 milliwatts. Reduced power can
reduce the size of the coverage zone, which may be desirable for multiple network
indoor applications. You can also 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.

HN-1010 Outdoor Base/Remote Station

HN-1010 Outdoor Base/Remote Station

Introduction

The HopNet Outdoor Base/Remote Station (HN-1010) features a low-cost, rugged,
compact, NEMA 4X/IP 66 enclosure for outdoor or harsh industrial environments.
You can use the HN-1010 with all HopNet products and with any existing WIT2410
network.

Data Transmission

The HN-1010 supports up to 62 remotes on a single network. You can operate 16
different networks in the same area without conflicts. The HN-1010 can easily
transmit over 1.0 mile line of sight. You can extend this range by adding a HopNet
Repeater (HN-2010) or by using gain antennas.

Automatic repeat requests (ARQ) and acknowledgments inside the radio are
transparent to the user equipment. User data rates of 230 Kbps are supported with
built-in CRC/ARQ error protocols. See below for jumper settings. The HN-3500
adapter can be used to adapt RS-232 signals to RS-485 in situations where long data
cable runs are required. The HN-1010 uses a 9-pin Conxall weatherproof connector
for power, data, and control signals. See the illustration below of the 9-pin Conxall
connector.

Data throughput is RS-485 Hybrid or RS-232 while flow control signals are single­ended RS-232. Factory default is RS-485 Hybrid. RS-232 is selectable through
internal user configurable jumpers.

Jumper Settings

The HN-1010 is shipped from the factory as an RS-485 Hybrid device. To change the
interface to the RS-232 option the following tasks must be performed:

− Remove Top cover.

− Change jumper settings so that J11, J12, J13 and J15 only are inserted

Jumper Configuration of HN-1010

You can operate the HN-1010 from any well-filtered 7.5 to 24 VDC power source.
The power supply should be capable of providing 750 mA peak current. Power
connects through the 9-pin connector. A polyfuse on the transceiver board protects
against short circuits.

Antenna Connection

The RF signal is brought in on a standard female TNC jack connector located on the
front panel. Use the following guidelines when installing the antenna:

• Be sure to strictly follow the antenna manufacturer’s installation instructions for

proper operation of the antenna.

8 HopNet Family of Products M-2410-0010, Rev -

HN-1010 Outdoor Base/Remote Station

• Be sure that you use the proper polarization for a gain type antenna. If you orient

the antenna with wrong polarization, a signal reduction of greater than 20 dB could
result.

• Use a low-loss RF feedline between the antenna and the HN-1010. Make the

feedline as short as possible to keep signal loss to a minimum.

• When installing the feedline, do not twist, stretch, or kink the cable.

• Be sure to securely fasten the cable and only use connectors that have been

recommended by the cable manufacturer.
