The WiSER2400.IP and the WiSER2400.Plus are IEEE 802.11b compliant
devices with built-in serial interfaces. They are desi ned to allow non-
wirelessly enabled serial devices to be connected and fully inte rated into an
802.11 Network.
The WiSER2400 receives data from equipment with serial ports; converts the
serial data into 802.11 compliant TCP or UDP data packets and transmits
these packets wirelessly. Conversely, the WiSER can receive wireless
packets, which it unpacks and delivers byte-by-byte to the destination
equipment/device throu h a serial port.
The WiSER2400 requires no device driver and is operatin system
independent. They can be used with almost any type of equipment that uses a
serial port, includin (but not limited to) cash re isters, electronic whiteboards
and navi ational instruments. Administration of the WiSER2400 is done
throu h a Windows based administrative software pro ram. The
administration software can be used to confi ure the unit’s operatin
parameters, administrative and local network settin s. It can also be used to
monitor the unit’s communication link conditions.
Fi . 1 WiSER2400.IP
The WiSER2400.IP comes with an RS-232 interface and a built-in
2dBi antenna. It comes supplied with a 5V DC power adapter.
The WiSER2400.Plus provides the same functionalities as the
WiSER2400.IP. It has an RS-232 DB-9 connector as well as a mini-
Phoenix connector for RS-485/422 interfaces. It accepts 5V DC to
32V DC power supply that has to be provided for separately by the
user. Input power connection is made throu h the mini-Phoenix
connector. It also comes with a DIN rail mountin clip and plate
assembly.
Note: Throu hout this manual, the term WiSER2400 is used to
refer to both the WiSER2400.IP and the WiSER2400.Plus

This chapter describes the functionality and operations of the WiSER2400
Dia nostic and Confi uration administrative software pro ram. The
WiSER2400 administrative pro ram is supported on Microsoft Windows®
98(SE), NT, Millennium, 2000, and XP.
To use the administrative pro ram to monitor and confi ure the WiSER2400,
the PC can be connected to the WiSER2400 either directly throu h the serial
port by cable or via a wireless network connection.
A connection selection window will pop up as shown on the ri ht when the
administrative pro ram starts.
Once the connection selection is chosen, the administrative pro ram will
display an interface as shown in Fi . 10 and Fi . 11 respectively, dependin
on whether the PC is connected to the WiSER2400 by serial port, or by a
wireless connection.
Warning: The administrative pro ram in serial port connection
mode will not work if another RS232 application pro ram is set to use
the same COM port. Make sure that no other application is connected
with the COM port when startin the administrative pro ram. In
Windows, any connection with a COM port is exclusive.
3.1.1 The Tabs
There are five Tabs in the administrative software interface window:
Link Status
Confi uration
Encryption

Each will be covered in detail below.

WiSER2400 wirelessly.
Fi . 10 shows the administrative pro ram interface when the PC is connected
with the WiSER2400 throu h the serial port by a cable. The user first needs to
select the proper COM port on the PC and its baud rate, byte size, and parity
(as shown in the top of Fi . 10) to match those of the WiSER2400 before
clickin on the “Connect” button to establish communication link between the
administrative pro ram and the WiSER2400 unit.
Defaults: Baud Rate: 9600 / Data bits: / Parity: none
Alternatively, the user can click on the “Detect…” button (as shown in the
bottom of Fi . 10) to have the software automatically detect the RS232
parameter settin s of the WiSER2400 at a iven COM port. The connection
between the PC and the WiSER2400 will be automatically made when the
administrative software succeeds in correctly detectin the parameter settin s
of the WiSER2400. Once the connection is made, the Connect button will turn
into a Disconnect button. Simply click on the “Disconnect” to terminate the link
between the PC and the WiSER2400.
Fi . 11 shows the administrative pro ram interface when the PC is wirelessly
connected to the WiSER2400. To connect the PC to the WiSER2400 via
wireless networkin , one needs to make sure that the WiSER2400 and the PC
runnin the administrative software are on the same subnet.
The default IP settin s for the WiSER2400 are:
IP address: 192.16 .11.191
Subnet mask: 255.255.255.0
The administrative pro ram, when started in the wireless connection mode,
will automatically scan for all the available WiSER2400 units on the network.
Alternatively, the user can force a scan by clickin the “Get MAC/IP” button as
shown in the top of Fi . 4b. The scan results will be displayed in a pull-down
list. The user then selects from the menu for the unit to be confi ured or
monitored.
