1. Introduction
Danger
* Do not allow physical impact. When damaged, turn o your network device, unplug
the AC plug of NX-1 from power outlet (unplug the network cable from Ethernet HUB
when receiving power over the Ethernet) and contact your point of purchase. Failure
to take this action could cause re or an electrical shock.
* In the following cases, turn o your network device, unplug the AC plug of NX-1 from
power outlet (unplug the network cable from Ethernet HUB when receiving power
over the Ethernet) and contact your point of purchase for a repair or inspection.
Failure to take this action could cause re or an electrical shock.
* When NX-1 emits a strange smell, heat, or smoke.
* When foreign objects (liquid, metal, etc.) gets into NX-1.
* Keep the cord and cables away from children. They may be injured or receive a shock.
* Do not disassemble or modify NX-1. Doing so could result in re or an electrical shock,
or cause NX-1 to malfunction.
* Do not disassemble or alter the AC adapter bundled with NX-1. Doing so could result
in re or an electrical shock, or cause NX-1 to malfunction.

Warning
* When unplugging NX-1, do not pull on the cord.
The cord may break resulting in re and/or electric shock. Pull only on the plug.
* When moving NX-1, turn o connected devices and NX-1 by unplugging the power
cables from the outlet (if you are receiving power over the Ethernet (PoE), unplug the
network cable from the HUB).
* Always use the AC adapter bundled with NX-1. Other AC adapters may cause NX-1 to
malfunction.
* Verify all cables are connected properly and safely before using NX-1.
* When NX-1 will not be used for an extended time, unplug the power cables of
connected devices and NX-1.
* Do not use or store NX-1 under the following conditions to avoid potential damage to

2-2. Features
NX-1 has the following features.
NX-1 features the Operating Mode, which consists of the following four operation modes.
You can make use of them for various purposes concerning use of wireless LAN products,
such as an environment survey prior to introduction, operating status monitoring, and
troubleshooting.
Survey Mode
Measures use of specied wireless channels and reports the result in chart.
Monitoring Mode
Monitors the surrounding wireless environment regularly and reports the results in
chronological order in charts.
Spectrum Analyzer
Measures radio noise that aects wireless LAN and reports the results in chart.
Capture Mode
Captures wireless LAN frames of specied channels.
Standalone operation
NX-1 can be installed in a target wireless environment for standalone operation and
enables you to make a survey without technical knowledge about operating the unit.
Remote control via a wired LAN
In the environment which allows communication with NX-1 via a wired LAN, you can
remotely collect wireless LAN environment information and view the analysis results
through the Web page of NX-1.

NX-1 User's Guide
2-3. Limitations and Precautions
The following limitations and precautions are applied to NX-1.
Limitations
- NX-1 does not support Short Guard Interval HT20 and cannot capture frames at the
corresponding transfer rates.
The communication at the corresponding rates is not reflected in the reports of the
Monitoring Mode and the Survey Mode.
- Depending on the performance of your USB storage, some frames can be missed and not
saved in the USB storage. Note that it is not guaranteed for all frames to be captured and
stored in all USB storages.
- The Capture Mode of NX-1 does not guarantee that all frames are captured correctly in
your wireless LAN environment.
Precautions
Do not perform the following actions during operation of the Operating Mode. The USB
storage may be damaged.
- Disconnect the USB storage from NX-1.
- Unplug the AC adaptor of NX-1 from an outlet (When receiving power over the Ethernet
(PoE), unplug the network cable).
Silex Technology will not be held liable for any damage to USB storages and/or data loss as
a result of use of NX-1.
