HARDWARE INSTALLATION AND CONFIGURATION
To connect the SDC-WB40NBT to a computer, follow these steps:
1. If not already installed, attach the four riser assembly mounting screws onto the breakout board. These screws
are installed from the bottom of the breakout board.
2. Connect the U.FL coax cable from the breakout board to the SDC-WB40NBT (the smaller central board). Connect
the coax to the WB40NBT's "main" connector.
Note: By default, the breakout board has a gray cable attached to the antenna port. Please remove this cable and
attach the longer black cable provided by Summit.

1. Plug the SDC-WB40NBT module into ST19, the 120-pin high-density connector situated near the four mounting
screws that were installed in step 1.
2. Connect an antenna with an SMA connector to the antenna port STA4.
3. Connect the USB-to-RS232 adapter to the position labeled ST3 DBU (RS232) on the Hoeft & Wessel breakout
board.
Note: Do not plug the USB-to-RS232 cable into a host PC at this time. Its driver must first be installed onto the host PC.
See Software Installation and Configuration for information on how to install the driver.

3. Download and set up a serial terminal emulator (which will be used to send the SDC-WB40NBT commands).
Note: A variety of emulators are available. In this Quick Start Guide, we use Tera Term.
To download and set up Tera Term, follow these steps:
a. Navigate to the Source-Forge (Tera Term) website: http://en.sourceforge.jp/projects/ttssh2/releases/
b.Download the emulator.
c. Run the downloaded file and navigate through the installer.
d.Open Tera Term.
e. Upon opening, Tera Term prompts for connection information. We are using a Serial Connection (not the
default TCP/IP).
f. Select Serial.
g.From the Port: drop-down menu, choose the COM port which has a description similar to: Prolific
Serial-to-USB Comm Port . Remember this COM port number.
h.To adjust the serial port settings, navigate to Setup > Serial port. Adjust the settings (as needed) according
to the following:
Port
The previously chosen port may not be set here. Change to the correct COM port
number, if necessary.
Baud Rate
115200 (Tera Term defaults to 9600 baud communications)
Data
8 bit
Parity
None
Stop
1 bit
Flow Control
None
i. Press OK to save the settings and to return to the terminal.
Note: Assuming all settings have been set properly you should now be able to communicate with the
SDC-WB40NBT. The terminal presented now is the Linux shell and behaves likewise.
4. Press Enter until you receive the following response from the SDC-WB40NBT:
Summit Data Communications
summit login:
5. Enter the user name and password. The default user name is root and the default password is summit .
Note: When entering the password, don't be alarmed if text or asterisks do not show. This is normal operation in
Linux.
After logging in, the following should display to indicate that you are now in the Linux shell:

USING LINUX ON THE SDC-WB40NBT
Common Terms
Shell –A command interpreter running on the Linux kernel.
Terminal –A terminal is a window which accesses the shell command interpreter. Summit accesses the shell using a
Tera Term terminal.
Scanning for Available Access Points
To get a list of available APs, type the following command:
# wl scan
Then type the following:
# wl scanresults
Note: If the wl scanrestults command indicates the device is not ready, it may be still creating the list of available access
points. Wait a few seconds and type the wl scanresults command again.
Establishing a Wireless Connection
The wireless bridge is pre-configured with a script (S45wireless) that loads the device driver for the radio and attempts to
make a connection. You can modify this script as needed.
The S95wireless script is located at:
/etc/init.d/S95wireless
Use the SDC CLI to establish a wireless connection. Refer to Wifi Networking Using the SDC CLI for more information.
To verify the status of a Wifi connection, the wl status command may be used:
#wl status
