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 is used for powering the device and for the u-center interface.
•
Odometer sensor measurements are provided from the vehicle CAN bus via CAN_H and CAN_L
pins on the front connector.
•
UART RS-232 connector is 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 selects the MCU UART.
2.
Connect the UART cable to the PC.
3.
Connect the USB cable to the PC. Check that the blue light on the front panel is on.
Checking u-center
4.
Open u-center.
5.
Connect to the receiver with
Receiver > Connection > COMxx
6.
Verify that the connection is established. Poll UBX-MON-VER, and check that the FWVER is correct
(LAP 1.30)
7.
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
⚠
CAUTION! Risk of data loss. Insufficient baud rate may result in data loss. Increase the UART1
baud rate when either the priority navigation mode or debug messages are enabled.
