Chapter 1 INTRODUCTION WiSER2400 is an 802.11b compliant, or WiFi, radio with a RS232 serial interface. The radio takes serial data from the equipment or computing device connected to it 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 (802.
operators. An end user simply plugs the pre-configured radio into a host equipment or computer equipped with a RS232 receptacle without ever being expose to this Utility program. The Utility program is simple to install and easy to use through its graphic user interface. The details are described in Chapter 3.
WiSER2400 WiFi Radio Key Features Configurable as either an Access Point or a Station Configurable as a dedicated pair of radios to replace a RS232 cable connection Plug & Play operation— o No driver on the host device is required for radio operation o Radio operation is independent of the operating system on the host equipment or device (Windows 98/2000/ME, Linux, Unix, embedded, etc.
Chapter 2 INSTALLATION OF WiSER2400 Installation of WiSER2400 Hardware Standard Hardware Items 2 WiSER2400 radios 1 2-foot RS232 cable 1 3-foot RS232 cable (option –S, or –N, or –P) 1 ac-dc adapter 1 USB power adapter 1 pair of Velcro mounting pads Power This radio connected to your equipment draws power from an AC adapter that plugs into a wall outlet. The radio connected to your computer draws the power from a USB power adapter cable that plugs into the USB port of a notebook or desktop computer.
Status LED’s Power on the WiSER2400 Radio, the LED’s on the front panel should exhibit the following patterns: LED Color Light Blinking Pattern Indication ON RX RED GREEN Steady on Steady on Proper power is supplied Unit linked to another unit or Unit is configured as an AP Unit not linked to any unit Unit transmitting RF signal Not in use Steady blink TX RED Flickering LINK YELLOW Steady on When the radio is configured as a Station, one of the most useful diagnostic tools may be the green RX LED:
Installation of WiSER2400 Software System Requirements To use the WiSER2400 Wireless Ethernet Adapter’s utilities software, your computer must meet the following minimum requirements: Windows® 95 (OSR2)/ 98 (SEC)/ME/2000/XP One COM port (with a DB-9 male connector or an appropriate adapter to connect to a DB-9 female connector) Installation To install the utility program, simply insert the CD-ROM provided copy the “WiSERUti.exe” file to the desired location on your PC.
Chapter 3 Diagnostic and Configuration Utility Overview This chapter describes the functionalities and operations of WiSER2400 Diagnostic and Configuration Utility program. The utility program can be used to configure, monitor, WiSER2400 radios. The WiSER2400 utility program is supported on Microsoft Windows® 95(OSR2), 98(SEC), Millennium, 2000, and XP. Figure 1 below is WiSER2400 utility main window.
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 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.
Figure 3. Radio Status Panels (AP: left; Station: right) The modes switch automatically depending on the role of the WiSER2400 radio unit connected to the COM port. When the radio unit acts as an AP, the radio status panel is shown in AP mode. Likewise, when the radio unit acts as a station, the radio statue panel is shown in STA mode. To retrieve or update the Radio Status Panel, click Refresh button at the button of the main window.
channel in use is automatically displayed in the appropriate fields in the Configuration panel. 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.
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.
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 fields are “grayed out” to disallow manual entries of WEP keys.
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: This allows user to choose from key 1 to key 4 for transmission. The default key is set to Key 1. c.
Chapter 4 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.
Poor Link Quality If the Signal Strength indicator is reasonably high (>20%) and the Link Quality is not zero, but the “Link Quality” 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 strongly reflecting (metallic) surfaces.
