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 (802.11) headers, unpacks the packet and delivers the data byte-by-byte to the destination equipment/device through the RS232 serial port.
Each WiSER2400.IP radio acts as a “Station” and operates in either infrastructure or ad-hoc mode in accordance to the 802.11 standards. As such, this radios enables RS232-interfaced devices to participate in a wireless Ethernet network. In this capacity, the radio, in addition to eliminating the RS232 cables, functions as a media converter for RS232-interfaced equipment and computing- devices.
The radio is fully self-contained in performing the conversion between serial data and wireless-Ethernet packets. That is, no device driver needs to be installed on the hosting equipment or computing device the radio is connected to. True Plug
&Play feature therefore is achieved with any equipment or computing devices with an RS232 port. This also means the radio can be used on equipment and /or computing-devices with any Operating Systems. This is particularly useful for instruments/equipment where the use of RS232 interface is utilized. Examples include cash registers, electronic whiteboards and navigation instruments.
WiSER2400 has a compact form-factor that blends easily into an office/ classroom environment. It also lends particularly well to portable applications. The specifications are given on the next page.
The utility program can be used to monitor the communication condition once the radio is in operation. The radio runs self-sufficiently without the aid of any driver program in the host equipment or computer connected to the radio. This utility program therefore is intended to be, in most cases, just a tool for the network operators. The utility is also needed to configure the WiSER2400.IP for both wireless and UDP/IP parameters. The utility program is simple to install and easy to use through its graphic user interface. The details are described in Chapter 3.
Note: The terms WiSER2400 and WiSER2400.IP are used interchangeably through out this document
