INTRODUCTION

The WiSER2400.IP and the WiSER2400.Plus are IEEE 802.11b compliant

devices with built-in serial interfaces. They are designed to allow non-

wirelessly enabled serial devices to be connected and fully integrated 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

equipment/device through a serial port.

byte-by-byte to the destination

The WiSER2400 requires no device driver and is operating system

independent. They can be used with almost any type of equipment that uses a

serial port, including (but not limited to) cash registers, electronic whiteboards

and navigational instruments. Administration of the WiSER2400 is done

Fig. 1 WiSER2400.IP

through

Windows based administrative software program. The

administration software can be used to configure the unit’s operating

parameters, administrative and local network settings. It can also be used to

monitor the unit’s communication link conditions.

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 through the mini-Phoenix

connector. It also comes with a DIN rail mounting clip and plate

assembly.

The remaining fields in the Encryption page are described below.

3.5 Encryption

Deny Unencrypted Data Frames: if checked, the WiSER2400 will

block unencrypted data frames from being received.

Transmission key: For selecting a key from Key 1 to Key 4 for

transmission encryption. The default key is set to Key 1. The

WiSER2400 will receive wireless packets encrypted with any key

from Key 1 to Key 4.

WEP key factor: Allows the user to choose how many frames the

Initialize Vector (IV) is reused for. Four options are available:

Every frame, Every 10 frames, Every 50 frames and Every 100

frames. The default is Every 100 frames.

The WiSER2400 supports Wired Equivalent Privacy (WEP) security

for both 64-bit and 128-bit encryptions. The Encryption page contains

two sections:

3.5.1 Encryption

This section allows the user to choose from three encryption options: 64 bits,

128 bits or none (disabled). The WiSER2400 uses the shared key scheme

when either 64 or 128-bit key is selected.

When the Apply button is clicked, the program validates all entered data and

prompts the user to re-enter the data if any of the entries are invalid. If all of

the data is valid, it will be applied to the radio unit.

Once the type of encryption is selected, use the following section as a

guideline on setting up encryption:

3.5.2 WEP Keys Creation

This section allows the user to generate the WEP encryption keys.

Notes:

There are 24 pre-fixed bits in either 64 or 128-bit encryption key. For 64-bit

encryption, there are 10 hexadecimal characters (40-bits) that need to be

generated by the user (example: 0A1B2C3D4E); for 128-bit encryption there

are 26 hexadecimal characters (104 bits) to be generated (example:

12345678901234567890ABCDEF).

There are two ways to generate the encryption key. One is to use Pass

Phrase automatically generate the key. Or, the user can manually input the

keys in the Manual Entry fields.

For automatic key generation, select Pass phrase and enter an arbitrary

combination of continuous alphanumerical characters into the Pass phrase

field. The maximum length allowed for the character string is 64. Click the

Apply button to save the encryption key setting.

To manually generate the key, select Manual Entry and enter the hexadecimal

numbers to the fields for Key 1 to Key 4. Click the Apply button to save the

encryption key setting.

APPENDIX

Troubleshooting

Blank Pages Appear When Opening the Administrative Program

Poor Link Quality

This is possibly due to the unavailability of the COM port. Check the Connection and If the Signal Strength indicator is reasonably high (>20%) and the Link Quality is not

Status fields at the bottom of the program’s main window. Press the Connect button zero, but stays in the Poor range, it could be due to one of the following reasons:

again to see if the status indicates “Connected.” If not, check to see if you have another

program running that accesses (or protects) the same COM port.

•

Make sure that radio interference is not present in the radio network.

Make sure that the radio is not surrounded by many strongly reflecting

(metallic) surfaces. With multiple reflecting surfaces between the radio in

question and the target radio, a severe multi-path problem may introduce high

bit error rate despite a strong Signal Strength.

Make sure that there is no severe packet collision caused by a “hidden node”

problem. A “hidden node” problem is a situation where the RF signal from two

or more Station radios cannot reach each other (but can reach the AP) (i.e.

The Bridge stations have no awareness of/cannot detect the existence of the

other station). In such situations, multiple Stations may attempt to transmit

data packet to the AP at the same time and cause packet collision. To solve

this problem, re-arrange the problematic Stations so that their RF signals are

mutually sensible to all Stations. There is no guarantee that the packet

collision can be entirely eliminated, but the severity can be reduced enough to

see visible improvement of the link quality.

No Radio Link

If the Link Quality indicator in the Radio Status panel shows 0%, check the following for

possible causes:

•

Make sure that the Signal Strength indicator under Radio Status panel is not

zero. A minimum of 20% is recommended. If the “Signal Strength” is less than

20%, the distance between the WiSER2400 and the targeted AP may be too

far. Decrease the distance between the radio pair to see if the radio link can

be improved.

•

Make sure that the encryption keys are entered correctly if WEP encryption is

enabled.

Make sure that there is no RF interference present in the radio network.

Radio Interference

No Data Transfer While the Radio Link is Good

You may be able to minimize RF interference by doing the following:

If the Link Quality indicator shows good link quality, but the host computer/equipment

cannot properly exchange data:

•

Although the WiSER2400, when properly configured, will seek a clear channel

to use, it cannot avoid interference if too many 2.4GHz interference sources

are present. A “clear” channel should be at least 20MHz, but preferably

30MHz, apart from any other channel in use. Find out what other usages are

in use in the vicinity and try to coordinate channel assignments with other

users.

•

Make sure the RS232 cables are properly connected to the radio and

computer/equipment.

•

Make sure that the RS232 cables in use are not defective.

Make sure that the COM port on the computer/equipment is available and not

used by another active program/process.

•

Reseat the WiSER2400 radio to a location where the interference is

minimized; in general, increasing the distance between radio pairs may cause

radio interference.

Avoid using 2.4GHz cordless phone in the vicinity of the radios.

Keep the computer with the WiSER2400 radio away from the microwave oven

and large metal objects.

•

Retrieve the “Configuration” information of the WiSER2400 by click on the

“Refresh” button. Make sure that the “IP setting” on the “Configuration” tab

are correct: IP addresses, port numbers, etc. A very clear indicator that

shows that there is a connection between the WiSER2400 radio and the

intended destination device is the “Dest unit’s MAC address” field. After

clicking the “Refresh” button a few times while the “Configuration” tab is

selected, this field should show the MAC address of the destination unit. If

this does not work, check the IP address settings.

Recovering from the Data Only Mode

Limited Warranty

There are two approaches for recovering the WiSER2400 radio from the Data Only

Mode. First is to use the Administrative software under wireless connection since the

WiSER2400 radio will still take configuration command from the wireless port even when

it is running Data Only Mode. Use the alternative approach if the WiSER2400 can only

be linked through a serial connection. The instruction for the alternative approach is

given below.

The seller warrants to the end user (“Customer”) that this product will be free from

defects in workmanship and materials, under normal use and service, for one (1) year

from the date of purchase from the seller or its authorized reseller. The seller’s sole

obligation under this express warranty shall be, at the seller’s option and expense, to

repair the defective product or part, deliver to Customer an equivalent product or part to

replace the defective item, or if neither of the two foregoing options is reasonably

available, The seller may, in its sole discretion, refund to the Customer the purchase

price paid for the defective product.

Have the WiSER2400 radio connected to the COM port of the PC

Start the Administrative software running the serial connection mode

Power up or power cycle the WiSER2400 radio unit

Within 10 seconds after the WiSER2400 has powered up, use the

Connect button in the administrative software to establish a serial link

with the WiSER2400 radio

All returns must be authorized by OTC Wireless, Inc. and accompanied by a Return

Materials Authorization (RMA).
