The relay board controls the operation of the device based on the indications provided by the display that acts as a user interface.   
Analog inputs highlighted in green, digital inputs (open/closed) highlighted in blue; then there are the inputs and outputs with line voltage which are highlighted in red.

**SOFTWARE/FIRMWARE**

The operation of the relay board is based on proprietary software generally identified as Firmware (FW).

The FW controls and regulates the operation of the device based on the operating parameters, inputs from the sensors and the settings given by the user on the display.

For obvious reasons the FW must be aligned with the SW of the display card.

#### Display Board RF13A00035

 

![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-18-2024-09-57-02-9377-AM.png?width=577&height=350&name=image-png-Sep-18-2024-09-57-02-9377-AM.png)

The display board, equipped with a plastic frame, is done by three NOT-DISCOMPOSIBLE parts; the display board, the SOM, that carries memory and processor, and the touch display.

SOM card (do not remove)

Wi-Fi Antenna

RS485 connector to relays board

USB connector for data exchange and SW update

SD Slot

Wired Ethernet connector

Backup battery

The display board is fixed to the front panel via 8 nuts and a gasket is installed between panel and display, protecting the display from water, grease and vapor infiltration.

In case of removal of the board, always replace this gasket because damage due to infiltration is not covered by the warranty. If replacement is for warranty Display board MUST BE RETURNED TO LAINOX

 

**SOFTWARE**

The operation of the display card is based on the Android operating system and on this OS is installed the NABOO application that below we will indicate as Software (SW).

When turned on, the operating system starts just like a smartphone; Once the operating system is booted, an image is presented during the start of the Naboo application.

If the display is replaced, check if there is a backup of the unit configuration; if any, load the configuration from USB, otherwise reconfigure the unit from the service level.

#### Display Board - Software update

 

![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-18-2024-09-58-42-9484-AM.png?width=562&height=265&name=image-png-Sep-18-2024-09-58-42-9484-AM.png)

Display board can be updated installing the latest SW version.

Is recommended to keep updated the SW in order to achieve bug fix and new features which can improve and extend cooking capabilities.

**On-line software update**

When connected to the cloud, the unit automatically shows on the status bar if a new software version is available.

Follow instruction on the display which will guide you to the update; when completed unit must be restarted.

If synchronization has been disabled, you can use the «check software update» button.

*If the Wi-Fi connection is unstable or slow, do not to use this update method.*

If the boot is unsuccessful and a) and b) continue to be displayed, the operating system is probably corrupted.

Contact LAINOX support to check if it's possible to recover the display

Display operate as an Android device and has a booting sequence with automatic launch of the Naboo application.

**Start-up sequence**

When switched on, the display flashes briefly to indicate that the sequence has started.

d) The application is starting (white since version 10)

e) The application is ready

In the event of a power failure, a large spanner symbol will appear on screen and will be needed some few seconds to have access to the functions.

Power failures are the main cause of damage to the operating system and database.

![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-18-2024-11-08-51-8441-AM.png?width=295&height=250&name=image-png-Sep-18-2024-11-08-51-8441-AM.png)

In the event of repeated reboots (3 times), the system will be completely reinstalled from the

 f) Will appear the Recover mask to let recover the system from the last backup

    If the reboot stops at d), it will be possible to delete the database or reinstall the application          from Maintenance with a click on Loading from mask c)

g) Enter “Maintenance”

#### Display Board – Maintenance

![](https://support.lainox.com/hs-fs/hubfs/image-png-Sep-18-2024-11-10-10-1253-AM.png?width=632&height=350&name=image-png-Sep-18-2024-11-10-10-1253-AM.png)

Possible to access to operating system functions through the maintenance window.

**Access**

When you keep pressed ***Loading*** during the booting sequence, you enter the *Maintenance* window g) which gives you access the data *(not for customers)* with the password ***«stools»***

**Install application from USB**

**Export database to USB**

**Delete database**

**Import database from USB**

 

Possible to access to operating system functions through the maintenance window.

In some few cases (if the booting sequence stops on screen d)), the issue can be solved by installing the application.

**Installing the application**

1\) Download the software (#name#.nbu file) from the service portal

2\) Rename the downloaded file #name#.nbu in #name#.*zip* and extract from this folder the files

3\) Rename the file #name#.apk in  *Lainox.apk* and copy it on the USB stick. For Compact units, rename the file as Lainox7h.apk (if horizontal) or Lainox7v.apk (if vertical)

Enter Maintenance mode, connect the USB, and select *Install app* from USB.

 

Possible to access to operating system functions through the maintenance window.
