USB type micro B port (see Ports)
Ports

• Two ports are present on the top side of the CU (as indicated in Figure 1):
• USB Type C port which is used to connect the glasses to the CU

USB Type Micro B port to access to CU in Debug Mode
LED Lights
The CU has four LED lights (as indicated in Figure 1):

• * Status LED

  • Bluetooth, Wi-Fi and GSM LEDs
    During Control Unit update operations, LED lights behaviour is typical and described in Control Unit Update.

Status LED
Operating system manage Status LED in this way:

• blinking red LED: external battery charge < 20 % and internal battery charge > 50 %
• steady red LED: external battery charge < 20 % and internal battery charge < 50 %

blinking violet LED: VisionAR smart glasses is not recognized by Control Unit
It is recommended to fix the LED light (e.g. blue color) when application is running. LED light color management is assigned to software application
Note: if the Battery Pack is disconnected from the Contol Unit, the Status LED is steady red
Bluetooth, Wi-Fi and GSM LEDs
The LEDs are programmable and can be turn on through a custom application when modules are active
CU Buttons
Univet Control Unit has different buttons as you can see in Figure 2:

1. Power button
2.  ESC
3. Up
4. Enter/Confirm
5. Down

Control Unit Before Starting

TURN ON/OFF
Here the procedure to turn ON and turn OFF the Univet Control Unit
TURN ON

2. Place the Control unit 20cm far from the body

Drive the power button up and release
TURN OFF
To turn off the Control Unit:

1. Drive the power button up and hold for 5 seconds. Now you can release the power button verifying that LED lights are not flashing and only red one is on
2. Disconnect the USB cable from the Control Unit and from VisionAR Smart glasses Remember that the Control Unit can work only when two subunits are connected

Control Unit – What’s in the box

The contents of the box are listed below:

1. Charger
2. Control Unit with mounted battery pack
3.  Spare battery pack
4.  Plug adapters
   Hidden by the spare battery there is also:  USB type A to type micro B cable (for charging purpose)

Control Unit – How to charge the battery pack

Here a panoramic of Univet Control Unit (Figure 1):

1. Status LED
2. Type USB C connector to link Control Unit and VisionAR
3. Type USB micro B connector to link Control Unit and PC for debugging operation
4. Clip for plug in/plug out operation

• Unhook the clip (Figure 2 [a]) of Control Unit bringing it down and split the two subunits (Figure 2 [b]) as it is reported in next figures:

• Check the battery status by clicking on battery pack button, as shown below (Figure 3):
• The number of green spots indicates charging value of the battery pack:
• 1 dot: battery charge between 0 – 25 %
• 2 dots: battery charge between 25 – 50 %
• 3 dots: battery charge between 50 – 75 %
• 4 dots: battery charge between 75 – 100 %
• Connect the battery pack to the charger with the USB cable, as pointed in Figure 4:
• type micro B interface to the battery pack (A)
• type A interface to the charger (B)
• Connect the charger to electric socket
• During battery charging period, a flashing green LED is displayed
• When charging process ends, green LED is fixed as show here (Figure 5):
