Page 4: Chapter 1 - Introduction
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. -

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. -
Page 10: Chapter 3 - Diagnostic And Configuration Utility
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. -
Page 11: Connection And Overall Status Panel
Figure 2. Connection and Overall Status Panel The pull-down menu allows users to select COM ports (RS232 serial port) so that the utility program knows where to connect to WiSER2400 radio unit. The pull- down menu becomes inactive and inaccessible when the connection between the WiSER2400 radio and the utility program is active. -
Page 12: Configuration Panel
Figure 3. Radio Status Panels (AP: left; Station: right) In general, the Radio Status Panel displays the firmware version, firmware release date, role, and communication channel used by the radio. The panel displays additional radio signal information such as the Port Status, Link Quality, and Signal strength. - Page 13 SSID. Network Type: this is the 802.11b mode the radio unit is running on. It can be either”Ad hoc” or “Infrastructure”. For WiSER2400.IP to connect with a normal AP, always select “Infrastructure” mode Please refer to IEEE 801.11 documentation for more information of the Network Type.

RS232 and WLAN Statistics Panel The transmission statistics of the RS232 (COM port) and Wireless Local Area Network (WLAN) is shown in this panel. To retrieve the statistics, click Refresh button located at the bottom of the main window of the utility program. The following explains the statistics shown in the panel: 1. -
Page 15: Security Panel
Security Panel This panel shown in Figure 5 enables users to configure security options for the WiSER2400 radios. WiSER2400 supports Wired Equivalent Privacy (WEP) encryption both 64bits and 128bits.The Security panel contains two sub-panels, Encryption sub-panel and WEP Keys Creation sub-panel. - Page 16 There are two methods to generate WEP encryption keys. One is to use auto key generation through the Passphrase field, and the other method is to manually input a set of keys in the Manual Entry fields. To auto-generate WEP encryption keys, select the radio button next to the Passphrase label and then the users can enter up to any 64 characters in the Passphrase field.
- Page 17 The Manual Entry Key 1/2/3/4 fields accept hexadecimal inputs as the encryption keys. If 64 bits encryption is enabled, each key field allows the user to enter up to 10 hexadecimal characters. If 128 bits encryption is enabled, each of the key field allows up to 26 hexadecimal characters.

Page 18: Chapter 4 - Udp/Ip Implementation
Chapter 4 - UDP/IP Implementation This section describes how the radio firmware composes RS232 data into UDP packets and sends them out, as well as how it receives the UDP packets and performs necessary checks. If all checks are passed, it retrieves the RS232 data from the packets, and sends the data out to RS232 cable. -

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. -
Page 21: Poor Link Quality
• Reseat the WiSER2400 radio to a location where the interference is minimized; in general, increasing the distance between the radio pair may cause radio interference. -
