Accessing the Web Interface

Step 1: Wait for the LED to turn on. The unit is powered on once the LED starts to glow.
Step 2: A Wi-Fi access point will become accessible on each unit. The SSID of the access point is koruza-primary or koruza-secondary. To connect use the password KoruzaV2Pro.
Step 3: Access the Web Interface. Go to if connected to koruza-primary, or if connected to koruza-secondary.
Step 4: You will be prompted to enter a username/password combination. The username is set to admin and the password is set to admin as well.
Step 5: After entering the provided credentials select the Unit Dashboard tab and proceed to the Coarse Alignment steps presented below.

Changing the Access Point SSID

To be able to change the Access Point SSID first connect to the unit using the method described above.
Step 1: Open the /etc/hostapd/hostapd1.conf file with a text editor, for example nano. Do so with sudo nano /etc/hostapd/hostapd1.conf
Step 2: Edit the line containing the ssid=koruza-primary or ssid=koruza-secondary and change it with your desired Access Point SSID. For example, ssid=my-new-ap.
Step 3: Save the file and reboot the unit with sudo reboot now.

Coarse Alignment

Step 1: Point the units against one another using the camera stream on the GUI as best as you can by hand. Use the marker set during calibration as a guide.
Step 2: When both units are coarsely aligned, tighten the screws on the KORUZA v2 Pro joint as to fixate orientation.

3. Fine Alignment using the Graphical User Interface

Step 3: Once both units are fixated, connect to the management interface of each unit. When you access the interface, you should see the camera view and additional data about each unit. The RX Power field indicates received power on the unit and should be used as a main guide during alignment procedure.
The interface is described in detail in the Graphical User Interface section.
Put the browser windows side by side for easier alignment.
Keep in mind that that movement of the unit has greater impact on the received power of the opposite unit than on the received power of unit being moved.
Step 4: Use the W, A, S and D keys on your keyboard or click on the buttons of the Primary Unit control section to align the KORUZA v2 Pro units. First, aim the centre of the red square to the centre of the unit to establish the link.
You can choose magnitude of single movement, by selecting Steps option above the camera view.
Step 5: Once the RX Power is greater than -25 dBm on both units, a link is established.
Step 6: Now, use the W, A, S and D keys to achieve the maximum receive power on the units.
Keep in mind that optimal position might not be when red square and the unit overlap.

3.1. Fine Alignment Strategy

Step 1: Try moving one of the units, say UNIT 1, left and right and stop at the position where most signal is received on the opposite unit, say UNIT 2. Try with Steps: 100.
Step 2: Once optimal position is located, move the same unit up and down and again stop at the position where most signal is received on the opposite unit.
Step 3: Repeat steps 1 and 2 on the opposite UNIT 2, now monitoring relieved signal on the UNIT 1.
Repeat steps 1, 2 and 3 until optimal signal is received on both units, reducing the steps magnitude in the process. Usually Steps 100 can be used on links up to 50 m and Steps 10 should provide sufficient accuracy for longer links.
