Setup
a. Connect the Vision-RTK 2 to the power supply connector (3). The voltage
supply level is 5-36 VDC, typically 3A@5V.
b. Connect the Vision-RTK 2 to a PC and access the web interface using one of
the following options:
1. Ethernet: connect via the Ethernet port (1). Access the web interface
with the address http://10.0.2.1
2. Wi-Fi: connect to the Wi-Fi SSID with the same reference name as the
Vision-RTK 2 (e.g. fp-5cbaa2) and use the password “1234567890”.
Access the web interface with the address http://10.0.1.1
c. In the section Configuration:
1. Networking, connect to an available Wi-Fi network with internet
access.
2. RTK, configure an NTRIP account to receive RTK corrections.
3. Fusion, adjust the options for the specific application (e.g. Tuning
mode).
d. Ensure the following points:
1. The Vision-RTK 2 is rigidly attached to the vehicle. For initial tests, it is
recommended to mount the sensor and antennas on the provided
aluminum bar to ensure the correct extrinsic parameters.
2. In Configuration →Camera, the camera view is not covered and is not
dominated by static scenes like the sky. Adjust the bottom or top part
of the camera view only if it has static objects like a vehicle hood.

e. In the section Positioning →Fusion Status, enable the real-time positioning
with the blue Start button. The Vision-RTK 2 initialization requires to be
outdoors with at least one antenna with an RTK fix solution.
f. Drive 2-3 minutes in RTK fix with some dynamic movement to converge the
IMU biases (e.g. driving a figure eight).
Interfaces
The Vision-RTK evaluation kit provides a UART connector for transferring data
in serial mode and a Wi-Fi connection or an Ethernet port for transferring data
in TCP/IP mode. The data is published with a custom Fixposition format.
Additional formats can be selected in the section Configuration →Fusion.
