Chapter 1 - INTRODUCTION
WiSER2400.IP is an 802.11b compliant, or WiFi, radio with an RS232 serial
interface.
The WiSER2400.IP radio takes serial data from the equipment or computing
device connected via its RS232 port, converts the serial data into 802.11-
compliant data packets, and transmits these packets with the RF modulation that
is compliant with the specifications of the 802.11b physical layer. On the
receiving end, the radio demodulates the RF signal, removes the Ethernet
(802.11) headers, unpacks the packet and delivers the data byte-by-byte to the
destination equipment/device through the RS232 serial port.
Each WiSER2400.IP radio acts as a “Station” and operates in either
infrastructure or ad-hoc mode in accordance to the 802.11 standards. As such,
this radios enables RS232-interfaced devices to participate in a wireless Ethernet
network. In this capacity, the radio, in addition to eliminating the RS232 cables,
functions as a media converter for RS232-interfaced equipment and computing-
devices.
The radio is fully self-contained in performing the conversion between serial data
and wireless-Ethernet packets. That is, no device driver needs to be installed on
the hosting equipment or computing device the radio is connected to. True Plug
& Play feature therefore is achieved with any equipment or computing devices
with an RS232 port. This also means the radio can be used on equipment and /or
computing-devices with any Operating Systems. This is particularly useful for
instruments/equipment where the use of RS232 interface is utilized. Examples
include cash registers, electronic whiteboards and navigation instruments.
WiSER2400 has a compact form-factor that blends easily into an office/
classroom environment. It also lends particularly well to portable applications.
The specifications are given on the next page.
The utility program can be used to monitor the communication condition once the
radio is in operation. The radio runs self-sufficiently without the aid of any driver
program in the host equipment or computer connected to the radio. This utility
program therefore is intended to be, in most cases, just a tool for the network
operators. The utility is also needed to configure the WiSER2400.IP for both
wireless and UDP/IP parameters. The utility program is simple to install and
easy to use through its graphic user interface. The details are described in
Chapter 3.

Key Features
Plug & Play operation—
o No driver on the host device is required for radio operation
o Radio operation is independent of the operating system on the host equipment or device
(Windows 98/NT/2000/ME/XP, Linux, Unix, embedded, etc.), as long as an RS232 port is
properly supported
Supports 64-bit and 128-bit encryption for secured communication
Industry standard IEEE 802.11b-compliant wireless interface
11Mbps data rate and automatic selection of lower data rate (5.5, 2 and 1 Mbps) in degraded RF
environment
Integrated omni-directional-antenna to provide best tradeoff between link-quality and mobility
Microsoft-Windows-based configuration utility
Applications
Standard-compliant wireless networking for computers and equipment with an RS232 interface
Embedded devices, tools, instruments, equipment and appliances that can benefit from the re-
configurability of wireless link yet are unfriendly to the installation of device-drivers
o
o Control/monitor equipment where mobility is required
POS equipment for stores where re-configuration is frequent
Chapter 2 -INSTALLATION OF WiSER2400.IP
Installation of WiSER2400.IP Hardware
Standard Hardware Items
1 WiSER2400.IP radio
1 3-foot RS232 –P cable
1 ac-dc power adapter
1 pair of Velcro mounting pads
Power
This radio connected to your equipment draws power from the provided AC-DC
power adapter that plugs into a wall outlet.
RS232 Connection
The WiSER2400.IP radio is shipped with one RS232 cable. This 3-foot cable is
intended for use with any RS232 equipment (whiteboard, instrument, etc.) and
has the specification listed below:
Option –P—terminates in a male DB-9 connector, no dc-power is available
from this cable
Connect the modular plug (which resembles an over-sized telephone plug) of the
RS232 cable to the modular jack (which resembles an over-sized telephone jack)
at the bottom panel of the WiSER2400 radio. Connect the DB-9 (9-pin, can be
female or male depending on the equipment) connector of the RS232 cable to
the RS232 port in the client equipment or computer.

Status LED’s
Power on the WiSER2400 Radio, the LED’s on the front panel should exhibit the
following patterns:
LED Color Light Blinking Pattern Indication
ON RED Steady on Proper power is supplied
Steady on Unit linked to any wireless stationRX GREEN
Steady blink Unit not linked to any unit
TX RED Flickering Unit transmitting RF signal
LINK YELLOW Steady on Not in use
The WiSER2400.IP radio is configured as a client Station and cannot be
changed. As a station, one of the most useful diagnostic tools may be the green
RX LED: a blinking green RX LED indicates the absence of a useful
communication link.
Once the hardware is checked out to work properly with the intended host device
or equipment, the radio can be secured in the desire location by the pair of
Velcro pads supplied.

Installation of WiSER2400.IP Software
System Requirements
For using the WiSER2400.IP Wireless Ethernet Adapter’s utilities software, your
computer must meet the following minimum requirements:
Windows® 95 (OSR2)/ 98 (SE)/NT/ME/2000/XP
One COM port (with a DB-9 male connector or an appropriate adapter to
connect to a DB-9 female connector)
Installation
To install the utility program, simply insert the CD-ROM provided. Copy the
“wue101.exe” file to the desired location on your PC.
Note that to use the WiSER2400.IP properly as intended, you must configure the
WiSER2400.IP radio to the appropriate IP [Internet Protocol] configurations as
your network.

Note: For the utility program to configure or monitor the WiSER2400 radio
through a COM port, there must be no another serial (RS232) program
that also accesses or control the same COM port.
Chapter 3 - Diagnostic and Configuration Utility
Overview
This chapter describes the functionalities and operations of WiSER2400.IP
Diagnostic and Configuration Utility program. The utility program can be used to
configure and monitor WiSER2400.IP radios. The WiSER2400.IP utility program
is supported on Microsoft Windows® 95(OSR2), 98(SE), NT, Millennium, 2000,
and XP. Figure 1 below is WiSER2400.IP utility main window.
Warning:The utility program may not work simultaneously with another RS232
application program since both programs would compete for the control to the
same RS232 serial (COM) port connecting the WiSER2400 radio.
