SX-560 Intelligent Programmable WLAN Module SX-560

SX-560
Intelligent Programmable WLAN Module
802.11a/b/g Wireless Solution for OEM Embedded Applications
High Performance, Low Power Usage, and Enterprise Security
The Silex SX-560 embedded WLAN Module is a high-performance lowcost solution that supports all of the major wireless networking
standards – 802.11a, 802.11b, and 802.11g. Its low power consumption
and a compact form factor make it ideal for battery powered portable
devices, but its extensive capabilities make it suitable for almost any
embedded WLAN application.
The SX-560 handles all of the TCP/IP and 802.11 network processing, so
it provides a fast and easy way to add wireless networking capabilities
to your device. Because it offloads the network processing, the
processor on your device operates more efficiently and there is a little or
no change required to your code. As a result, you increase your bottom
line by reducing your time to market, making your products more
competitive, and lessening the need for in-house wireless expertise.
Key Advantages
SX-560 key competitive advantages include:
•
Very low power consumption (ideal for battery operated systems)
•
Linux operating system with user programmability
•
Enterprise level management and security
Features
Low Power Consumption. The SX-560 uses a minimum amount of power
during transmitting and receiving, and its power management reduces
power usage during periods of inactivity.
Linux Operating System with User Programmability. The SX-560 uses the
Linux operating system and is designed to allow users to easily add
new features. With a 200MHz 32-bit processor, 16MB of RAM and 8MB
of flash memory, the SX-560 has plenty of capacity to handle complex
user applications.
Highly Secure The SX-560 includes enterprise-level security features
including access control lists, complete protocol and application
enable/disable control, read and write configuration passwords, and
SNMP community name configuration. It features the most extensive
wireless security in the industry, including 802.1x Extensible
Authentication Protocol (EAP) with all major EAP types and WPA2,
WPA2-PSK, WPA, WPA-PSK, and WEP wireless security.
Enterprise Management. Silex's ExtendView management software
provides advanced features such as the ability to monitor, configure
and update multiple SX-560 modules simultaneously over the network.
Management capabilities are also available via TELNET, SNMP, web
browser, and a dedicated serial console port. For added control, AT
commands and console commands can also be sent via the two serial ports.
Two Serial Ports Plus Dedicated Console Port. The SX-560 provides two
serial ports that can used to connect to RS-232 or UART interfaces in
your device. These ports operate at speeds up to 921Kbps with modem
controls. A third serial port is also included for use as a dedicated
console port.
USB, SPI and IIC ports.
.
The USB V1.1 host port supports speeds up to
12Mbps, while the SPI port operates at 25MHz (the optional SX-Virtual
Link Windows/Macinosh software/firmware is available to access the
USB port; user-written Linux software is required for the SPI and IIC ports).
Serial Port Emulation Software. The SX-560 includes software that
emulates a standard Windows COM port (for example, COM3). This
allows you to use your existing Windows applications without change.
General Purpose I/Os (GPIOs). The 9 GPIOs can be used for custom
applications like driving LEDs and sensing switches, or for modem
signals in conjunction with the serial ports.
SNMP Traps and E-mail Alerts. Users can be notified immediately of any
status changes on the GPIOs or serial ports via SNMP or E-mail.
Antenna Diversity. The SX-560 has two U.FL antenna connectors for
improved quality of transmission and reception.
Easy to Use. The SX-560 features a compact form factor with
through-holes for flexible mounting options. A 40-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 SX560 module in their equipment.

OEM Interface
Specifications
The OEM interface allows OEMs to add functionality via a
daghtercard. Power is also input through this interface. This is a 40pin 0.5-mm pitch surface-mount header (Hirose DF12-40DS-0.5V or
equivalent). Pin assignments are shown below.
