Description
The RN-134 “SuRF” board is field ready, WiFi certified
802.11 b/g solution. The SuRF board has the
flexibility to connect directly to a standard RS232
interface or through the TTL UART interface to
embedded systems. The status LEDs and jumpers
enable rapid prototyping and integrating into existing
systems.
The RN-134 is built upon Roving Networks RN-131
WiFly-GSX module. The WiFly GSX module
incorporates a 2.4GHz radio, processor, Full TCP/IP
stack, real-time clock, FTP, DHCP, DNS and web
server. The RN-131G is the smallest, lowest power
802.11 b/g module available. The module supports
adhoc and infrastructure networking.
In the simplest configuration the hardware only
requires four connections (PWR, TX, RX, GND). In
cases where power is available on the RS232 DB9
connector of your application, the RN134 can be
directly wired to create an instant serial to Wifi
network link.
Additionally, the analog sensor interface provides
direct connections to send temperature, acceleration
and other analog data without requiring additional
hardware. The WiFly GSX module is programmed and
controlled with a simple ASCII command language.
Once the WiFly GSX is setup it can scan to find an
access point, associate, authenticate and connect
over any WifI network.

Having this jumper on at power up also arms the restore factory reset function. After power up, if jumper 1 is
toggled on and off five times while the module the configuration will be RESTORED to the initial settings. This is
very useful in cases where the module is mis-configured and no is long responding to commands.
