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. On the receiving end, the radio demodulates the RF signal, removes the Ethernet

Chapter 3 - Diagnostic and Configuration Utility Overview This chapter describes the functionalities and operations of WiSER2400.IP Diagnostic and Configuration Utility program. The utility program can be used to configure and monitor 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 a

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 displays up-to-date connection status. It has a pull down menu for choosing COM ports, a Connect button, and a text field displaying connection status. Figure 2. Connection and Over

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. Configuration Panel This panel contains the following fields: SSID, Network Type, Baud rate, Channel, Max Bytes/Pkt, End Frame Byte of this unit. MAC addresses, IP add

In addition, there are two buttons 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 sending the ‘Config’ command to the radio unit that sets its configuration with above fields. Followings are the detail descriptions of the fields: SSID: The SSID that this radio would connect to. 32 characters maximum. An empty entry is acceptable but

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. RS232 Statistics: a. COM Sent: This number is the total bytes that the Unit sends through the connected COM port. b. COM Received: This number is the total bytes that

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. Figure 5 Security Panel Encryption sub-panel This sub-panel allows user to adjust the security level as needed. There are three radio buttons to select the encryption levels, and only one ra

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. Click the Apply button to apply the encryption key setting. Notice that when this method is selected the Manual Entry f

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. The remaining fields in the Security Panel are described below. a. Deny Unencrypted Data Frames: if checked, the firmware will block unencrypted data frames from being received. b. Transmission key:

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 packet header, the firmware only sets the important fields in the packet header, other less important fields are set with correct, fixed value

b. UDP header: i. Source Port number = “UDP Port” in the “This Unit” portion in the configuration panel. ii. Destination Port number = “UDP Port” 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/Pkt” field is in the “Configuration Panel.” (See section II for detail). v. UDP Check sum = calculated over UDP header and serial data. c. RS232 Data: this is the

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 running program that access the same COM port. No Radio Link If the Link Quality indicator in the Radio Status panel shows 0%, check the follo
