Attaching a USB-to-TTL serial adapter to the expansion board with an adjoining cable harness allows
convenient access and control of the UART interface from the PC through the ANT-B10 header.
Figure 8 shows the USB adapter attached to ANT-B10 through the standard 1.27 mm pin header.

☞
As ANT-B10 is powered by the USB-to-Serial Adapter there is no need for external power supply.
To connect ANT-B10 to the host PC:
1. Plug in the USB-to-Serial adapter
2. Open the Windows Device Manager to identify the COM port number of the board.
3. Use s-center [7] or your preferred terminal emulator to establish the serial connection to the COM
port.
4. Connect the COM port to the s-center tool [7] or the terminal emulator with the following port
settings:
•
115200 kbps
• 8 data bits, no parity, 1 stop bit (8N1)
• Flow control enabled using RTS/CTS
3.3.2 Pin description for UART connection
Using the cable harness, connect the following pins from the ANT-B10 header to USB-to-Serial
adapter:
• UART_TXD (pin 16)
•
UART_RXD (pin 18)
•
UART_CTS (pin 14) – optional for UART flow control
• UART_RTS (pin 12) – optional for UART flow control
• GND (pin 15 or 17)
• +3V3 (pin 2)
☞
If flow control is not used the UART_CTS pin is internally pulled down, but it is good practice to
connect UART_CTS to GND .
