Installation of WiSER2400.IP Software System Requirements For using the WiSER2400.IP Wireless Ethernet Adapter’s utilitie s software, your computer must meet the fo llowing 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 connect[...]

Chapter 3 - Diagnostic and Configuration Utility Overview This chapter describes the f unctionalities and operations of WiSER2400.IP Diagnostic and Configuration Utility program. The utility program can be used to configure and monitor WiSER2400.IP radi os. The WiSER2400.IP utility program is supported on Microsoft Windows® 95( OSR2), 98(SE), NT, [...]

In general, the main window consists of five panels: Connection and Overall Status, Radio Status, Configuration, Security , and RS232 and WLAN Statistics . Connection and Overall Status Panel The Connection and Overall Status panel, shown in figure 2, controls and maintains the serial connection, and disp lays up-to-date connection status. It has a[...]

Figure 3. Radio Status Panel s (AP: left; Station: right) In general, the Radio Status Panel di splays 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. Configuration Panel This panel conta[...]

In addition, there are two bu ttons on this panel. The “Default Setting…” button is to set the Max Bytes/Pkt and End Frame Byte to 6 bytes per packet and 0x0D (Carriage Return) respectively. The “Apply” button on this panel is for s ending the ‘Config’ command to the radio unit that sets its configuration with above fields. Followings[...]

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 botto m of the main window of the utility program. The following explains the statistics shown in the panel: 1. RS232 Statistics : a. COM [...]

Security Panel This panel shown in Figure 5 enables users to configure security options for the WiSER2400 radios. WiSER2400 supports Wi red Equivalent Privacy (WEP) encryption both 64bits and 128bits.The Secu rity panel contains two sub-panels, Encryption sub-panel and WEP Keys Creation sub-panel. Figure 5 Security Panel Encryption sub-panel This s[...]

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 encrypt ion keys, select the radio button next to the Passphrase label and then the users can enter up to any 64 characters i[...]

The Manual Entry Key 1/2/3/4 fields accept hexadecimal inputs as the encryption he remaining fields in the Security Panel are described below. a. Deny Unencrypted Data Frames : if checked, the firmware will block b. c. oose how many frames the keys. If 64 bits encryption is enabled, each key field allows the user to enter up to 10 hexadecimal chara[...]

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. When composing the UDP/IP pa[...]

b. UDP header: i. Source Port number = “UDP Port ” in the “This Unit” portion in the configuration panel. ii. Destination Port number = “UDP Po rt” in the “Dest. Unit” portion in the configuration panel. iii. UDP Length = UDP header length + data length. This data length would be =< “Max Bytes/Pkt” value. iv. The “Max Bytes[...]

Chapter 5 - Troubleshooting Blank Pages Appear When Open the Utility Program It is possibly due to the unavailability of the COM port. Please pay attention to the Connection and Overall Status field next to the Connect button. Press the Connect button again to see if the status indicates “Connected. ” If not, check to see if you have another ru[...]

Poor Link Quality If the Signal Strength indicator is reasonably high (>20%) and the Link Quality is not zero, but the “Link Qualit y” stays in the Poor range, it could be due to one of the following reasons: • Make sure that radio interference is not present in the radio network. • Make sure that the radio is not surrounded by many stro[...]
