Introduction
HopNet products are built around the WIT24xx 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
The HN-250 and HN-250X are NEMA 4X weatherproof versions of the
HopNet product line. The HN-254, which is an HN-250 with a 4 ft. cable, is
also available. The interface to the 250 and 250X allows the Host to
communicate with the Remote unit through an integrated 50 ft (15 meter)
cable. The HN-250 and 250X can act as either bases or remotes.
The HN-250 Remote has an internally mounted 6 dBi patch antenna. The
built-in antenna of the HN-250 case greatly eases outdoor installation since
no antenna feedline cable or adapters are needed. The 6 dBi antenna gain
increases the radiated EIRP to +30 dBm when the high power setting is
selected and the effective receiver sensitivity to –98 dBm. The HN-250X has
a TNC connector for attaching an external antenna and a mounting kit (part
no.: HN250X-MKIT) that accommodates both the HN-250X and any of the
following external antennas:
CORNER249
CORNER2414
OMNI249
OMNI2412
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 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 86
channels and switches channels over 100 times a second to achieve high
reliability throughput.
HopNet Data Integrity
An on-board 1 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.
Flexible Power Management
The power can be set at 10mW, 100mW (default) or 250mW using the
included software. 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.
Advanced Features
HopNet modems have many advanced features:
•Employ frequency hopping technology with up to 86 channels in the
2401 to 2475 MHz frequency range
•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 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

Getting Started
A pair of HN-250s is set up by performing the following steps:
•Install the HopNet Wizard configuration program on a PC
•Connect the HN-250 to the PC
•Set one HN-250 as a base radio
•Run a communications test
These steps are described in detail below. Other steps you may want to
perform include:
•Change the baud rate
•Change the radio network number
•Change how fast the radios change frequencies
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-250 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-250 to the PC.
Connect the serial adapter box to a serial port on the PC using the serial
cable provided.
