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— 

No driver on the host device is required for radio operation 

Radio operation is independent of the operating system on the host equipment or device 
(Windows 98/2000/ME, Linux, Unix, embedded, etc.), as long as a RS232 port is properly 
supported 

 

Automatic clear channel selection when configured to operate as a dedicated radio pair 

 

Supports 64-bit and 128-bit encryption for secured communication 

 

Industry standard IEEE 802.11b-compliant wireless interface; Interoperable with AP and Client 
radios from other vendors) 

 

Enable a RS232-interfaced equipment to participate in an Ethernet network via an 802.11b-
compliant Access Point 

 

11Mbps data rate and automatic selection of lower data rate (5.5, 2 and 1 Mbps) in degraded RF 

Applications 

 

Standard-compliant wireless networking for computers and equipment with a RS232 interface

 

 

Embedded devices, tools, instruments, equipment and appliances that can benefit from the re-
configurability of wireless link yet are unfriendly to the installation of device-drivers

 

Control/monitor equipment where mobility is required

 

POS equipment for stores where re-configuration is frequent
