Factory default is hardware flow control disabled; CTS and RTS are not required.
PIO’s are not 5.0 VDC tolerant. If using a 5.0 VDC circuit, input, PIO and UART input pins require a
resistor divider. A suggestion is to use a 10K resistor in series with 20k resistor to ground.
2.4. Status Indictors
PIO 4, 5 and 6 are active high and can be connected to external LEDs to provide network, connection and
data status.
3. Configuration
3.1. Entering Command Mode
Upon power up, the device will be in data mode. To enter command mode, exactly the three characters $$$
must be sent. The device will respond with CMD.
While in command mode, the device will accept ASCII bytes as commands.
To exit command mode, send exit<cr>. The device will respond with “EXIT”.
Parameters, such as the SSID, channel, IP address, Serial Port settings, and all other settings can be viewed
and configured in command mode.
ASCII characters can be sent through a terminal emulator connected to the UART or via Telnet. When
using the UART communications settings should match the settings used when RN-131g connects, for
example: the default is 9600 baudrate, 8 bits, No Parity, 1 stop bit, and hardware flow control disabled.
Use TeraTerm as your terminal emulator. Please DO NOT use HyperTerminal as it is known to have issues
with our products. TeraTerm can be downloaded from our website:
http://www.rovingnetworks.com/support/teraterm.zip.
Type $$$ on in the terminal emulator. You should see “CMD” returned to you. This will verify that your
cable and comm. settings are correct. Most valid commands will return an “AOK”, response, and invalid
ones will return an “ERR” description.
To exit command mode, type “exit“<cr>.
