DDC
Fully compatible with the I
2
C industry standard, available for communication with an external
host CPU or u-blox cellular modules, operated in slave mode only. Default messages activated
as in UART1. Input/output protocols available as in UART1. Maximum bit rate 400 kb/s.
SPI Allow communication to a host CPU, operated in slave mode only. Default messages activated
as in UART1. Input/output protocols available as in UART1. SPI is not available unless the
D_SEL interface is set up accordingly (see D_SEL interface).
TIMEPULSE (1 Hz Nav) 1 pulse per second, synchronized at rising edge, pulse length 100 ms
Table 8: Default messages
With firmware version 1.00B03 it is not possible to use the UART2 as an RTCM interface.
Refer to the u-blox ZED-F9P Interface Description [2] for information about further settings.
The ZED-F9P outputs NMEA 4.1 messages that includes satellite data for all GNSS bands
being received. This results in many more NMEA messages being output for each navigation
period. Please ensure the UART1 baud rate being used is sufficient for the set Navigation rate
and the amount of GNSS signals being received.
