PRODUCT DESCRIPTION

The WDS iNET 300 transceiver is designed to provide wireless
Ethernet connectivity over long distances. The transceiver comes in
two models—Access Point and Remote.

Three types of Remote units are available—the Ethernet Bridge, the
Serial Gateway, and the Dual Gateway. Table 1 summaries the dif­ferent interfaces for each type of radio.

A transceiver can be configured by the owner to operate as an Access
Point or as a Remote with some restrictions. Only the Dual Gateway
Remote units can be reconfigured as an Access Point. Ethernet Bridge
and Serial Gateway Remotes cannot be reconfigured as Access Points
unless they are first upgraded to Dual Gateway type. This is accom­plished with an “Authorization Key” purchased from the factory. Each
one of these individual software keys is associated with the serial
number of the corresponding unit.

Transceivers serve as either an “Access Point” or “Remote.” An
Access Point (AP) is a wireless hub that usually provides connectivity
into a wired Ethernet LAN/WAN. From a radio perspective, an Access
Point serves as the network’s “master station” providing synchroniza­tion data to all associated Remotes within its network.

WDS CYBER SECURITY SUITE

The operation and management of an enterprise is becoming
increasing dependent on electronic information flow. An accompa­nying concern is the cyber security of the communication infrastruc­ture.

The iNET 300 transceiver is capable of dealing with many common
security issues. Table 2 profiles security risks and how the transceiver
provides a solution for minimizing vulnerability. In all cases, the

rity Configuration

Menu should be reviewed and set to the required
parameters for your environment. Please refer to the User’s Guide

INSTALLATION PLANNING

This section provides steps for installation and start-up of the equip­ment.

General Requirements

There are three main requirements for installing the transceiver. They
are: adequate and stable DC power, a good antenna system, and the
correct interface between the transceiver and the data device. The
Installation Reference Chart (center of this guide) shows a typical
Remote installation. Access Point stations typically use omnidirec­tional antennas whereas Remotes typically use directional antennas
such as a Yagi. Otherwise, the installations are similar.

INSTALLATION STEPS

A typical product shipment consists of a transceiver, a power con­nector and this start-up guide.

Below are the basic steps for installing a transceiver. Should further
information be needed, see “TECHNICAL ASSISTANCE” on Page

of this manual for information on contacting the WDS Technical

20

Services Group. You will also find support information at the Wireless
Data Systems Web site:

It is highly recommended that the Access Point unit be installed first.
With this plan, you can quickly check the operation of each associated
Remote as it is placed on the air.

www.sinosun.cn.

NOTE:

Transceivers are shipped from the factory set to the “Remote”
mode unless they are marked differently.

Step 1—Mount the Transceiver

Mount the radio to a stable surface. (Fasteners/anchors or screws are
not supplied.) Four threaded holes are located on the bottom of the
radio that are suitable for connecting mounting hardware. Use 6-32 x
1/4 inch (6 mm length) screws to attach mounting hardware to the
bottom of the radio. Figure 1 shows the mounting dimensions.

CAUTION

POSSIBLE

EQUIPMENT

DAMAGE

Screws used to hold the mounting brackets to the radio
case should be SAE 6-32 and should not extend farther
than 1/4 inch (6 mm) into case. This will prevent dam­age to the transceiver’s internal PC board.

Step 2—Install the Antenna

To minimize radio frequency interference, the antenna should be
mounted at least nine inches (> 23 cm) from the connected device(s),
sensors and other components of the system. Additional information
on antenna selection and installation is provided in the

WDS iNET Series User’s Guide

.

Step 3—Measure & Connect DC Power

The DC power applied to the transceiver must be within 10–16 Vdc
and be capable of continuously providing up to 2 Amperes. A power
connector with screw-terminals is provided with each unit. Strip the
wire leads to 6 mm (0.25"). Be sure to observe proper polarity as
shown in Figure 1 with the positive lead ( + ) on the left.

Performance Optimization

After the basic operation of the network has been verified, you may
wish to optimize its performance using the suggestions given below.
The effectiveness of these techniques will vary with the amount of
data being handled.

Optimize Received Signal Strength

Check the received signal strength indicator (RSSI) for an adequate
signal level from the radio network’s Access Point. (RSSI is available
through the Menu System.) In the absence of interference, signal
levels that are sufficient to provide reliable operation (with a 15 dB
fade margin) are: ≥ –86 dBm @ 256 kbps, ≥ –82 dBm @ 512 kbps.

If the signal levels are lower, it may be necessary to reposition the sta­tion’s antenna for better reception/signal strength.

Minimize Packet Retries

If the Wireless Packet Statistics’ retry packet counter is unacceptably
high, several techniques can be used to improve it. These include iden­tifying interference and taking corrective steps such as skipping some
radio frequencies from the hopping pattern, increasing the gain of the
Remote unit’s antenna system, relocating the Remote’s antenna, or
installing a repeater system.

Blocking Out Zones

The transceiver uses channels in the 336–344 MHz spectrum, with
selectable hopping from 1 to 25 channels.

NOTE:

All radios (AP and Remotes) must be set to use the same chan­nels in order to establish a link. If this is not done, the radios
will not connect.

Usage key for Channel Configuration Menu:

n (no) = Radio channel is not used
y

(yes) = Radio channel is used

NA

(not available) = Radio channel is not available

Other selections on Channel Configuration Menu:

Clear All—This command clears all entries in the Channel Config

Menu, resetting the available channels to “no usage.” Channels that
are not available for use will appear with a notation of or

NET 300 Series Start-Up Guide12 i

NA

. These

channels are not available because of pre-existing conditions, and are
not user-configurable.

Enter Channels

—This allows selection of the channels used for fre­quency hopping operation. You can enter a selection using any of the
methods below:

a. One or more individual channel numbers separated by com-

mas (example:

1,3,6,9

)

b. A range of channel numbers separated by a dash

(example:

c. One of the keywords (example:

6-10

)

all, even, odd

)

d. A combination of individual channels and channel number

1,3,6,9,16-20,25

)

NOTE:

ranges (example:

The selection of particular channels will result in an indication
of y. Be aware that these channels do not become active until
the Commit Changes selection is invoked.

Commit Changes—

This re-boots the radio and loads the active chan-

nels into the frequency list for frequency hopping operation.

AIMING DIRECTIONAL ANTENNAS

In general, signal levels stronger than –80 dBm will provide reliable
communication in the network. Directional antennas usually require
some fine-tuning of their bearing to optimize the received signal
strength. The unit has a built-in received signal strength indicator
(RSSI) that can be used as an aid to optimizing the received signal
level. The measurement and antenna alignment process usually takes
less than 10 minutes at each unit.

RSSI measurements and Wireless Packet Statistics are based on mul­tiple samples over a period of several seconds. The average of these
measurements is displayed by the Menu System.

In the steps below, the path to the Menu System item is shown in bold
text.

TROUBLESHOOTING

It is best to begin troubleshooting at the Access Point, because the rest
of the system depends on it for network synchronization and configu­ration. If the Access Point has problems, the operation of the entire
network will be affected.

All radios in the network must meet these basic requirements:

• Adequate and stable DC power

• An efficient and properly aligned antenna system

• Secure connections (RF, data & power)

iNET 300 Series Start-Up Guide

15

• Proper programming of the unit’s operating parameters, espe-

cially Device Mode selection (Access Point/Remote), Network
Name, and IP Address

• The correct interface between the radio and the connected data

equipment (proper cable wiring, data format and timing)

Table 4 provides suggestions for resolving common system difficul-

ties using the front panel LEDs as a guide. Table 5 on Page 17 pro­vides guidance using the Menu System as a tool. If problems persist,

FACTORY SERVICE

If return of the equipment is necessary, please contact the WDS Tech­nical Support Team. You will be issued a Service Request Order
(SRO) number. The SRO number will help expedite the repair so that
the equipment can be repaired and returned to you as quickly as pos­sible. Please be sure to include the SRO number on the outside of the
shipping box, and on any correspondence relating to the repair. No

equipment will be accepted for repair without an SRO number.

A statement should accompany the radio describing, in detail, the
trouble symptom(s), and a description of any associated equipment
normally connected to the radio. It is also important to include the
name and telephone number of a person in your organization who can
be contacted if additional information is required.

The radio must be properly packed for return to the factory. The orig­inal shipping container and packaging materials should be used when­ever possible. All factory returns should be addressed to:

Shenzhen Sinosun Technology Co., Inc.

Customer Service Department

3A17,South Plaza Cangsong Building, Tairan Industry & Trade Zone

Futian District, Shenzhen,Guangdong, China

When repairs have been completed, the equipment will be returned to you by
the same shipping method used to send it to the factory. Please specify if you
wish to make different shipping arrangements. To inquire about an in-process
repair, you may contact our Product Services Group .
