2.2 Configuration
Command Mode (vs Normal Data mode)- Upon powerup, the device will be in data
mode. To enter command mode, The characters “$$$” must be sent. The device will
respond with “CMD”. To exit command mode, send “exit<cr>”. The device will respond
with “EXIT”. Parameters, such as the SSid, Channel, IP address, Serial Port settings,
and all other settings can be viewed and configured. While in command mode, the
device will accept ASCII bytes as commands.
Use a normal RS-232 pass through cable from PC passing ASCII characters through the
terminal to the RN-111b. The communications settings should match the settings used
when RN-111b connects, for example: the default is 115,200bps, 8 bits, No Parity, 1
stop bit, and hardware flow control disabled.
Run your favorite terminal emulator, Roving Networks provides a free one, Teraterm, at
http://www.rovingnetworks.com/support/teraterm.zip
.
Type “$$$” on your 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 Error description.
Commands that are not recognized will return a “ERROR: Unknown Cmd”.
To exit command mode, type “exit“<cr>.
NOTE1 :
You can enter command mode locally over the serial port at any time when not
connected, and also when connected if the appropriate settings are enabled.
