Chapter 1
INTRODUCTION
WiSER2400 is an 802.11b compliant, or WiFi, radio with a RS232 serial
interface.
The radio takes serial data from the equipment or computing device connected to
it 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.
The radio can be configured either as a “Station” or as an “Access Point” in
accordance to the 802.11 standards. It can operate either in the ad hoc or the
infrastructure mode defined by the 802.11 standards. As such, this radios
enables RS232-interfaced devices to participate in an 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.
Due to the fact that most existing RS232 applications involve RS232 interfaces
on both ends of a communication link, standard WiSER2400 radios are currently
shipped in pairs. However, a single WiSER2400 radio is perfectly capable of
connecting RS232-interfaced equipment wirelessly to another non-RS232-
interfaced 802.11b radio as long as software exists on the other end to properly
receive the data in Ethernet packets. For such single-radio applications, please
contact OTC for more information.
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 a 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 widespread.
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. An end user simply plugs the pre-configured radio into a host
equipment or computer equipped with a RS232 receptacle without ever being
expose to this Utility program. The Utility program is simple to install and easy to
use through its graphic user interface. The details are described in Chapter 3.

INSTALLATION OF WiSER2400
Installation of WiSER2400 Hardware
Standard Hardware Items
2 WiSER2400 radios
1 2-foot RS232 cable
1 3-foot RS232 cable (option –S, or –N, or –P)
1 ac-dc adapter
1 USB power adapter
1 pair of Velcro mounting pads
Power
This radio connected to your equipment draws power from an AC adapter that
plugs into a wall outlet. The radio connected to your computer draws the power
from a USB power adapter cable that plugs into the USB port of a notebook or
desktop computer.
Power can also be injected from the WiSER2400 over the RS232 cable (Option –
S and -N) to the equipment connected to the radio.
RS232 Connection
A pair of WiSER2400 radios is shipped with two RS232 cable. One of the cables
is 2 feet long and always has a female DB-9 connector at one end. This 2-foot
RS232 cable is used to connect a computer in a standard configuration. The 3-
foot cable is intended for use with any RS232 equipment (whiteboard,
instrument, etc.) and comes in one of the options listed below:
Option –S—terminates in a female DB-9 connector, when connected to a
powered-on radio, pin 1 supplies 5V, up to 350mA DC power
Option –N—terminates in a male DB-9 connector, when connected to a
powered-on radio, pin 7 supplies 5V, up to 350mA DC power
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.
Standard WiSER2400 radios operate at a data rate of 9600 baud. WiSER2400-M
operates at data rate of 19,200 baud. The WiSER2400 radio, however, is
inherently capable of supporting data rate up to 115K baud. Contact OTC for
applications that require customized or utility-configurable data rate.

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 another unit or Unit is
configured as an AP
RX GREEN
Steady blink Unit not linked to any unit
TX RED Flickering Unit transmitting RF signal
LINK YELLOW Steady on Not in use
When the radio is configured 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. If you are using a pair of the radios in a dedicated
point-to-point link, good radio communication is expected only if the green RX
LED’s on both radios are steadily on.
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 Software
System Requirements
To use the WiSER2400 Wireless Ethernet Adapter’s utilities software, your
computer must meet the following minimum requirements:
Windows® 95 (OSR2)/ 98 (SEC)/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
“WiSERUti.exe” file to the desired location on your PC.
Notice that the operation of the WiSER2400 radio is independent of the Utility
Program. Therefore, it is NOT necessary to install the Utility on the RS232
equipment/computer that connects to a WiSER2400 radio. For example, if you
connect an electronic whiteboard wirelessly to a network using a pair of
WiSER2400 radios, you need not to install Utility Program on the whiteboard and
you will not be able to! You can configure the WiSER2400 radio on a PC installed
with the Utility Program, disconnect it from the PC, and then connect it to the
whiteboard. While the Utility program must run on a computer equipped with
Microsoft Windows, the radio can operate with computers/equipment of any OS.

Also, notice that to configure or monitor the radio with the Utility program,
the computer cannot be running another program that also access the
same COM port.
Chapter 3
Diagnostic and Configuration Utility
Overview
This chapter describes the functionalities and operations of WiSER2400
Diagnostic and Configuration Utility program. The utility program can be used to
configure, monitor, WiSER2400 radios. The WiSER2400 utility program is
supported on Microsoft Windows® 95(OSR2), 98(SEC), Millennium, 2000, and
XP. Figure 1 below is WiSER2400 utility main window.
Warning: The utility program may not work simultaneously with another RS232
application program since both programs compete for the access to the same
COM port (RS232 serial port) connecting the WiSER2400 radio.
Figure 1. Main Window of WiSER2400 Utility Program
In general, the main window consists of five panels: Connection and Overall
Status, Radio Status, Configuration, Security, and RS232 and WLAN Statistics.
