Ensure all RTCM messages are set to transmit from UART1 and the baud rate is set to 460800,
otherwise the ZED-F9P and ODIN-W2 cannot communicate. Wrong settings can occur if the ZED-
F9P firmware is updated or the ZED-F9P UART1 is set to its default state. Ensure that the UART1
port protocols are set to “None” for input and “RTCM3” for output to prevent input of the received
rover messages. Then place a jumper at position “OE3” as shown in Figure 19, this will connect the
ODIN-W2 and ZED-F9P UARTs to provide transmission of RTCM messages to the rover.
Keep the USB connected to the PC, however disconnect u-center from the ZED-F9P USB port and
connect to the ODIN-W2 USB Virtual Com Port. This will allow viewing and logging of the rover C099-
F9P message data via the return Wi-Fi link.
Connect the GNSS antenna, ensuring use with the supplied ground plane and place in good GNSS
visibility conditions.
A Wi-Fi connection is established between reference and rover boards when the rover C099-F9P is
powered up. The ODIN-W2 activity LED is set blue when the base and rover have connected and
flashes when data transfer is occurring. Look for acquisition activity shown in u-center to confirm the
rover is operating correctly.
⚠
Ensure that any rover ZED-F9P output messages and configurations required are set before
connecting the reference as this can only be done via the dedicated ZED-F9P USB connection.
Ensure that the configuration is saved to Flash to avoid reverting to default operation after power
cycling.
u-center will now show the rover GNSS information via the reference C099-F9P ODIN-W2 connection:

Check that the rover has obtained a RTK Fixed mode in u-center Data view:
