3.1.3 Default interface settings
Interface Settings
UART1 output
38400 baud, 8 bits, no parity bit, 1 stop bit.
NMEA protocol is enabled by default and GGA, GLL, GSA, GSV, RMC, VTG, TXT messages are
output by default.
UBX and RTCM 3.3 protocols are enabled by default but no output messages are enabled by
default.
UART1 input
38400 baud, 8 bits, no parity bit, 1 stop bit.
UBX, NMEA and RTCM 3.3 input protocols are enabled by default.
UART2 output
38400 baud, 8 bits, no parity bit, 1 stop bit.
UBX protocol cannot be enabled.
RTCM 3.3 protocol is enabled by default but no output messages are enabled by default.
NMEA protocol is disabled by default.
UART2 input
38400 baud, 8 bits, no parity bit, 1 stop bit.
UBX protocol cannot be enabled and will not receive UBX input messages.
RTCM 3.3 protocol is enabled by default.
NMEA protocol is disabled by default.
USB Default messages activated as in UART1. Input/output protocols available as in UART1.
I2C
Fully compatible with the I2C
1
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 D_SEL pin is
set to low (see the D_SEL section).
Table 1: Default interface settings
Refer to the u-blox ZED-F9T Interface description [2 ] for information about further
settings.
By default the ZED-F9T outputs NMEA messages that include satellite data for all GNSS
bands being received. This results in a high NMEA load output for each navigation period.
Make sure the UART baud rate used is sufficient for the selected navigation rate and the
number of GNSS signals being received.
3.1.4 Basic receiver configuration
This section summarizes the basic receiver configuration most commonly used.
3.1.4.1 Communication interface configuration
Several configuration groups allow operation mode configuration of the various communication
interfaces. These include parameters for the data framing, transfer rate and enabled input/output
protocols. See Communication interfaces section for details. The configuration groups available for
each interface are:
Interface Configuration groups
UART1 CFG-UART1-*, CFG-UART1INPROT-*, CFG-UART1OUTPROT-*
UART2 CFG-UART2-*, CFG-UART2INPROT-*, CFG-UART2OUTPROT-*
USB CFG-USB-*, CFG-USBINPROT-*, CFG-USBOUTPROT-*
