increase this port speed to 115200bps using u-center. Additionally, but less often needed, the UART2 can be
configured for NMEA output. In general, we don't use UART2 for anything but RTCM correction data, so we
recommend leaving the in/out protocols as RTCM.
If you've got the ZED-F9P setup for base station mode (also called survey-in mode) the UART2 will output RTCM3
correction data. This means you can connect a radio or wired link to UART2 and the board will automatically send
just RTCM bytes over the link (no NMEA data taking up bandwidth).
SPI
The ZED-F9P can also be configured for SPI communication. By default, the SPI port is disabled. To enable SPI
2
close the SPI jumper on the rear of the board. Closing this jumper will disable the UART1 and I C interfaces
(UART2 will continue to operate as normal).
Antenna
The ZED-F9P requires a good quality GPS or GNSS (preferred) antenna. For a secure connection, we include an
SMA female connector. To make the most out of the ZED-F9P, you'll need a multi-band GNSS antenna and an
SMA male connector to mate.
