Note *: In order to evaluate the functionality of the CSRmesh Network, multiple devices need to be paired,
necessitating the procurement of multiple Evaluation units.
EVALUATION KIT MAIN BOARD:
The interfaces of the evaluation kit main board (ABBTM-NVC-BM-EVK) includes: DB9 RS232, USB UART (please visit
http://www.ftdichip.com/Drivers/VCP.htm for latest driver), 3.5mm jack audio input/output, several buttons, LEDs.
In addition, mounting places are reserved on the main board for soldering the Apple authentication coprocessor (2.0B or
2.0C). So it can also be used as a demo or test platform of Abracon’s iAP over Bluetooth solutions.
The main board also contains SPK_OUT and MIC_IN jack. There’s audio amplifier converting the differential audio output
from the Bluetooth module to single-ended, which can be output directly to a common 3.5mm headphone. And with on
board MIC bias circuits, a microphone can be inserted directly

1. USB power & virtual COM: Mini B socket to power the board. And if USB to COM chip (label by 4) is mounted, it also
acts as a virtual COM port (USB to COM, a driver for Windows is needed).
2. DB9 port: This can be used to connect to a RS232 COM port.
3. DCE, DTE switch: Switches the connections of the TX and RX signals to the DB9’s pin 2&3.
4. USB connection to the adapter board: Mini B socket connect the USB D+/- to the adapter board sockets. With proper
firmware, the Bluetooth module can act as a USB HID device, or USB CDC device (so a virtual COM port to Bluetooth
SPP is achieved). And DFU (device firmware update) works on this port.
5. USB UART IC, FTDI’s FT232.
6. RS232 level shift chip for the DB9 RS232 port.
7. Reset button and Jumper: Reset button to reset the Bluetooth module on adapter board. The jumper set if it’s a high level or
low level trigger reset. Please also connect the “RESET” jumper in connector “23”.
8. Digital power switch: Switch for main 3.3v power supply. When switched to “ON” position, the corresponding LED will
light.
9. Digital power circuits: Power supply to adapter board and on board digital circuits.
10. Jumper selector for COM connection: Route the UART from the adapter board to DB9 or USB UART port.
11. Audio power switch: Switch for the 3.3v power supply of the audio headphone amplifier. It is also used as the mic bias.
When switched to “ON” position, the corresponding LED will light.
12. Audio power circuits. Power the on board audio amplifier and MIC Bias.
13. AUX LED 1: Connect to PIO2 of the adapter board. The function depends on firmware.
14. 3.5mm audio output jack.
15. Audio headphone amplifier. The differential audio output from the adapter board (connector labeled as 27) is amplified
and output to the 3.5mm jack
16. AUX LED 2: Connect to PIO3 of the adapter board. The function depends on firmware..
17. Button1: Connect to PIO3 of the adapter board.
18. Audio input jack: mic input
19. Microphone Bias circuit: Connect a microphone in 3.5mm jack and the signals are processed and routed to
MIC_LN,MIC_LP of the adapter board.
20. Button2: Connect to PIO4 of the daughter board.
21. DB25 parallel connector, for Abracon internal use only.
22. Parallel port circuits.
23. Jumpers to connect/disconnect signals to adapter board.
24. The socket of adapter board.
25. Mount place for Apple’s Authentication Coprocessor: 2.0C.
26. Mount place for Apple’s Authentication Coprocessor: 2.0B.
27. Jumpers to connect/disconnect signals to adapter board.

SERIAL INTERFACE COMMUNICATION
In this demo we use a tool “AccessPort” (Freeware, can be downloaded here http://www.sudt.com/en/ap/index.html) to
access the COM ports in Windows. Customers can use other tools (such as HypterTerminal) in a similar way.
1. Set the proper settings of the RS232 port.

2. When an adapter board (a ABBTM-NVC-MDCS42-CON is used here) plugged and the power is switch on, it might
show,
