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
port.
4.
Connect the COM port to the s-center tool
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.
