The advantages of wireless networking are obvious. But as an OEM device 

manufacturer, how can you easily and securely implement wireless 

capabilities in your devices? 

The solution is the SILEX SX-550 Module, the first embedded networking 

solution that supports all of the major wireless networking standards – 

802.11a, 802.11b, and 802.11g – as well as 100Base-T and 10Base-T wired 

Ethernet. The SX-550 provides the most extensive network security 

capabilities in the industry, so it can be used in virtually any application or 

environment that requires wireless communications. – The SX-550 

increases your bottom line by reducing your time to market, making your 

products more competitive, and lessening theneed for in-house wireless 

expertise. It enables you to easily add wired or wireless network 

connectivity to your devices with such features as:

The SX-550 serial port runs at speeds up to 921.6Kbps with full modem 

control. The SX-550 also includes a second serial port for use as a dedicated 

console.

The SX-550 is available in models with wired Ethernet only, or with both 

Ethernet and 802.11a/b/g wireless capabilities. The two models are 

program compatible, so you do not need to develop separate software in 

order to support both.

The GPIOs can be used for custom applications like driving LEDs and 

sensing switches, or for modem signals in conjunction with the serial ports.

The SX-550 includes software that emulates a standard Windows™ COM 

port (for example, COM3). This allows you to use your existing 

Windows-based applications without any changes.

The SX-550 can be configured as a transparent bridge between Ethernet 

and 802.11a/b/g. This allows an Ethernet-enabled device to communicate 

wirelessly without modifications required to your existing software.

The SX-550 consumes very little power during inactive periods, making it 

ideal for battery powered applications.

The SX-550 has two U.FL antenna connectors for improved quality of 

transmission and reception.

The SX-550 features a compact form factor with through-holes for flexible 

mounting options. A40-pin connector header for the serial and GPIO 

signals simplifies the hardware interface to your device.

An available developer's kit provides the required hardware, software tools 

and documentation for OEM customers to easily integrate the SX-550 

module in their equipment. The developer’s kit includes value-added 

programmable features, such as APIs for custom SNMP and Email 

notification on the network. For example, you can use the available GPIOs 

to eliminate the need for an additional processor and therefore to reduce 

cost.

Security is critical for enterprise networks. In fact, some network managers 

will not allow devices on their networks that are not compatible with their 

security standards. Consequently, the SX-550 is designed to work with all 

major security standards. It supports 802.1x Extensible Authentication 

Protocol (EAP) with TLS, TTLS, LEAP, FAST and PEAP to provide the most 

robust network authentication. For wireless security, the SX-550 works with 

the latest Wi-Fi Protected Access 2 (WPA2) Enterprise and Personal (PSK) 

security, as well as WPA and WEP. The SX-550 also includes other 

enterprise-level security features such as access control lists, complete 

protocol and application enable/disable control, read and write 

configuration passwords, and SNMP community name configuration.

The SX-550 is easy to configure and offers several options for management. 

In addition to a built-in web browser interface, SILEX provides ExtendView, 

a Windows utility for easy configuration and management. A console 

accessible via TELNET or the UART is available for more sophisticated 

diagnosticsand configuration. The SX-550 is also compatible with the 

Simple Network Management Protocol (SNMP) for compatibility with most 

popular network management systems. In addition, the SX-550 can be 

managed by the attached device using AT commands and console 

commands sent via the serial port. The SX-550 firmware is stored in flash 

memory, which means it can be easily updated.
