Step-by-step example
This step-by-step guide uses the example from section B.1.1.
Assumptions:
•
User is familiar with u-center.
•
USB will be used for powering the device and for the u-center interface.
•
Odometer sensor measurements will be provided from the vehicle CAN bus via CAN_H and CAN_L
pins on the front connector.
•
UART RS-232 connector will be used for the configurable CAN.
•
RealTerm is used as the PC terminal application for the configurable CAN.
Connecting the device
1.
Connect a cable between SEL_MCU_N and ground. This will select the MCU UART.
2.
Connect UART cable to PC.
3.
Connect USB cable to PC. Check that the blue light on the front panel is active.
Checking u-center
1.
Open u-center.
2.
Connect to the receiver:
o
Receiver > Connection > COMxx
3.
Verify that the connection is established. Poll UBX-MON-VER, and check that the FWVER is
correct (MDR 2.10)
4.
Update the receiver if necessary (
Tools
>
Firmware Update
).
Configuring the receiver
Receiver configuration can be set with UBX-CFG-VALSET message and the appropriate
configuration keys.
1.
Disable output messages on I2C (MCU is connected to I2C):
o
CFG-I2COUTPROT-UBX
= false
o
CFG-I2COUTPROT-NMEA
= false
2.
Enable automatic alignment:
o
CFG-SFIMU-AUTO_MNTALG_ENA = true
3.
(Optional) Enable priority navigation mode (10 Hz):
o
CFG-RATE-NAV_PRIO
= 10
o
CFG-UART1-BAUDRATE
= 115200
4.
(Optional) Enable debug messages with the following commands based on the used serial
protocol:
a.
On USB: B5 62 06 8A 3B 00 00 07 00 00 3E 02 91 20 01 3F 01 91 20 01 39 02 91 20 01 28 06
91 20 01 7A 02 91 20 01 0D 01 91 20 01 08 01 91 20 01 09 00 91 20 01 18 00 91 20 01 16 02
91 20 01 2F 02 91 20 01 5E 73
b.
On UART: B5 62 06 8A 3B 00 00 07 00 00 3C 02 91 20 01 3D 01 91 20 01 37 02 91 20 01 26 06
91 20 01 78 02 91 20 01 0B 01 91 20 01 06 01 91 20 01 07 00 91 20 01 16 00 91 20 01 14 02
91 20 01 2D 02 91 20 01 48 DF
⚠
The UART1 baud rate will need to be increased when the priority navigation mode is enabled, or if
debug messages are enabled.
