Quick Start Guide
Minicom Setup
To set up Minicom on Ubuntu Linux host, follow these steps:
At the command prompt, type sudo apt-get install minicom.
Open Minicom (sudo minicom –D /dev/ttyUSBn –b 115200 -8 –o –l) where ttyUSBn matches the
enumerated USB virtual serial port. This command line provides the correct configuration requirements to
the Minicom application
Serial Port Configuration
No matter which terminal emulation program you are using, you must configure the serial port to match the
requirements of the WB communications.
Adjust the settings (as needed) according to the following:
Port
Must match the COM port of your USB-to-RS232 cable
Baud Rate
115200 (TeraTerm defaults to 9600 baud communications)
Data
8 bit
Parity
None
Stop
1 bit
Flow Control

Start Communication with the WB50NBT from the Host
Connect the 12v power supply to the wall outlet and the barrel connector to the SC jack on the BB40NBT

Wait until the WB50NBT is done booting and you see the following prompt:
Summit Data Communications
summit login:
Enter the username and password. The default user name is root and the default password is summit.

When entering the password, don't be alarmed if text or asterisks do not show. This is normal
operation in Linux.

The terminal presented now is the Linux shell on board the WB50NBT and behaves likewise. After logging
in, the following should display to indicate that you are now in the Linux shell: #
Important Note about No Serial Output
In some BB40NBT boards, the UART_3V3 jumper nearest the Debug UART port can become loose or unseated,
which results in no serial output.
If you find you have no serial output, check that this jumper is tightly seated
