1 Introduction

The C101-D9C board is a convenient tool that allows customers to become familiar with the u-blox NEO-D9C QZSS L6 receiver. The board provides facilities for evaluating the product and demonstrating its key features. NEO- D9C is a QZSS L6 receiver that brings QZSS Centimeter Level Augmentation Service (CLAS) support to u-blox GNSS modules, enabling centimeter-level navigation. The receiver can also track the experimental MADOCA service transmitted on the QZSS L6 signal. The C101-D9C application board offers:

NEO-D9C module for use as QZSS L6 correction data receiver
USB connection for communication and power supply
L6 antenna connection for receiving the satellite data stream
Arduino shield connection

1.1 Package contents

The delivered package contains:

C101-D9C board
Multiband antenna (L1/L2/E5b/L6)
Antenna ground plane (12 cm circular)
USB interconnect cable
Jumper connectors

Prior to using the board, it is useful to download the appropriate evaluation software and keep handy the documents listed in the Related documents section.

2 C101-D9C product overview

2.1 Components

C101-D9C houses the NEO-D9C QZSS L6 receiver. The board is powered from the USB cable connection or via Arduino shield. The main components of the board are listed below and shown in Figure 1 and Figure 2:

Native USB port
FTDI USB bridge
SMA RF connector and antenna supply capability (L-band)
UART2 interface through Arduino shield
NEO-D9C RESET button
NEO-D9C SAFEBOOT button

2.2 Jumpers

The board is delivered with the following default jumpers:

J6: This jumper provides 3.3 V power supply to an external active antenna plugged to the SMA RF connector. The current limit circuit is also enabled up to 60 mA.
J8: This jumper switches the communication from the UART2 of the NEO-D9C to the UART1 or UART2 of the C099-F9P, when connected via the Arduino shield (refer to section 4.1 for further details).

For further details, see the C101-D9C schematic in Appendix C.

3 C101-D9C standalone operation

This section provides some quicksteps to enable NEO-D9C standalone operation and connecting via u-center (see u-center user guide [3]).

Connect the supplied L6 band antenna to the RF SMA connector.
Connect the USB to a Windows PC, this will power the board. The FTDI and USB drivers will be installed automatically from Windows Update when you connect the board for the first time.
The power LED will turn on in blue color. · Start the Device Manager utility from Windows. Two new ports will be visible under the Ports tab: the USB Serial Device is the Native USB port and the USB Serial Port is the FTDI USB bridge port, as shown in Figure 5.

Start u-center and connect to one of the COM ports. If you are using the FTDI USB bridge, make sure the baud rate in u-center is set to 9600.
Poll UBX-MON-VER message and check the content as shown in Figure 6 .
Poll or enable the UBX-RXM-QZSSL6 message to check the received correction data.

For further details regarding the UBX-RXM-QZSSL6 message, see the related Interface description [4].

4 C101-D9C operation with C099-F9P

It is possible to use the C101-D9C board together with C099-F9P. Figure 9 shows how to interface the C101-D9C board with the C099-F9P board. Two types of connections are available:

USB interface (through PC)
Arduino shield interface (UART2 direct connection)

When the USB connection is used, the corrections are provided through the host computer. Security checks and data conversion are the responsibility of the user application, as well as the forwarding of the corrections to the ZED-F9P.

The provided multiband antenna can be used in combination for ZED-F9P and NEO- D9C, RF signal splitter is needed. For further details, see the antenna specification in Appendix B.

4.1 C101-D9C/C099-F9P via Arduino shield

Figure 9 shows the placement of the Arduino connectors on the C101-D9C board and Figure 10 shows how to physically connect the C099-F9P board to the C101-D9C board via the Arduino shield. Jumper J18 on the C099 board is needed for the ZED-F9P to receive the correction data on UART1 port. See the C099 application board User guide [5] for further details.

the jumper

For further details, see the C101-D9C schematic in Appendix C. UBX protocol needs to be enabled in output on the UART2 interface of the NEO-D9C to allow the communication, using the following configuration item: CFG-UART2OUTPROT- UBX=1 For further details regarding receiver configuration, see the related Interface description [4].
