'''6-48V Intelligent Automotive grade Power Supply'''<br><br>
==Introduction==
The DCDC-NUC was designed to provide user specified(+12V or +19V) regulated power output from a wide input voltage(6V-48V). Default output setting is set to +12V.<br>
It has a range of intelligent functions not found in any traditional USB DC-DC converters.<br>
The unit is able to send ON/OFF ‘pulse signals’ to motherboards based on filtered input voltage levels or Ignition sensing, making it an ideal device for automotive or battery powered installations.<br>
Two main [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Operating_modes'''modes of operation'''] are possible:DUMB and AUTOMOTIVE.<br>
The output voltage setting (12V or 19V) can be changed through the
[http://wiki.mini-box.com/index.php?title=DCDC-NUC#Configuration_switches '''Configuration switches'''] .<br>
The configuration switches can also be used to enter bootloader mode for updating firmware which is detailed in [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Bootloader_Mode '''Bootloader Mode'''] section.<br>
More advanced parameters are detailed in the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Parameter_List '''Parameter list'''] which can be configured using the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Configuration_Software'''Configuration Software'''].<br>

==Operating modes==
The operating modes can be selected by setting the NUCMODE parameter to 0(DUMB mode) or 1(AUTOMOTIVE mode) using the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Configuration_Software'''Configuration Software''']. The default setting is AUTOMOTIVE.
For basic operation, you would need to connect a power source to the input connector. Polarity is marked on the PCB. See [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Diagram_.26_Schematics Diagram & Schematics] section for further details<br>
Without any further settings if the input conditions are satisfied the unit will generate +12V regulated.<br>
Further parameters can be customized by changing in the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Parameter_List Parameter List].
For configuration or firmware update USB connection is sufficient.<br>

===Dumb Mode===
;Starting the unit
:In this mode starting can be performed by applying an input voltage higher than the value set by the VIN_MIN_STARTUP parameter.In order to filter out unwanted noise the input voltage should be higher than this threshold for the duration set by the VIN_COUNT parameter.<br>
:12V output and Thump output will be activated.<br>
:After output is ON and a timeout elapses set by the MOB_PULSE_TOUT parameter, the motherboard will be pulsed with a 500ms pulse set by the MOB_PULSEWIDTH parameter.

;Stopping the unit
:During ON state output will be only turned OFF immediately if the filtered input voltage becomes less than the threshold set by the VIN_MIN_RUNNING parameter.<br>

===Automotive Mode===
;Starting the unit
:In this mode Starting can be performed by applying input voltage higher than the value set by the VIN_MIN_STARTUP parameter and applying ignition voltage higher than the IGN_HIGH_THRESHOLD parameter.<br>
:The input voltage should be higher than VIN_MIN_STARTUP for the duration set by the VIN_COUNT parameter.<br>
:The Ignition voltage must be higher than IGN_HIGH_THRESHOLD for the duration set by the IGN_COUNT parameter in order to filter out unwanted noise in automotive environment.<br>
:After Ignition is considered ON output will be turned ON after IGN_ON_TO_OUTPUT_ON_TOUT elapses.<br>
:12V output will be activated. Thump output will be activated after timeout elapses set by the THUMP_TOUT parameter.<br>
:After output is ON and a timeout elapses set by the MOB_PULSE_TOUT parameter, the motherboard will be pulsed with a 500ms pulse set by the MOB_PULSEWIDTH parameter.<br>

;Stopping the unit
:During ON state output will be only turned OFF immediately if the filtered input voltage becomes less than the threshold set by the VIN_MIN_RUNNING parameter.<br>
:If Ignition voltage becomes lower than IGN_LOW_THRESHOLD and Ignition canceling is over (set by the IGN_CANCEL_TOUT parameter) a shutdown sequence will be initiated
:If Ignition is considered OFF the motherboard is pulsed for shutdown after IGN_OFF_TO_MOB_PULSE_OFF_TOUT elapses.
:After the HARD_OFF_TOUT timeout elapses the output will be turned OFF and the unit will enter in a low power state.

===Motherboard control===
The following options are available to control the motherboard by pulsing the on/off pins on the motherboard.
First the the motherboard on/off pins should be connected to the P4.1,P4.3 pin on the P4 [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Interface_connectors '''Interface_connector'''].<br>
The pulse width is 500ms by default which can be altered by changing MOB_PULSEWIDTH parameter from the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Parameter_List '''Parameter_List'''].<br>
There are various ways to control the motherboard depending the configuration of the CONFIG1 register from the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Parameter_List '''Parameter_List'''].<br>
Example:If startup of the motherboard is not needed when input is present, the startup pulse can be disabled by setting CONFIG1.b1 to 0.<br>
The same way the shutdown pulse can be inhibited by setting CONFIG1.b2 to 0.<br>
There are cases when motherboard started(ON) or OFF presence must be detected in order starting/stopping by pulses behavior work properly.<br>
For example the Operating System could be shutdown already from software. In case the unit is is a shutdown sequence not knowing this piece of information would lead by sending the shutdown pulse which would wake up instead the system.<br>
There are two kinds of feedback information to detect motherboard status.<br><br>
The first detection mode is by measuring the consumed output power, knowing that a motherboard when started consumes much more power than when in standby.<br>
In order to enable this feature the following steps should be performed:<br>
1. Enable this feature, CONFIG1.b3 should be set to 1.<br>
2. Observe and note the consumption of the connected motherboard when in standby and when is ON.
Our unit measures the output power(POUT) which is displayed in the configuration software.<br>
3. Set POUT_HIGH_THRESHOLD and POUT_LOW_THRESHOLD parameters from the [http://wiki.mini-box.com/index.php?title=DCDC-NUC#Parameter_List '''Parameter_List'''] accordingly with a good margin. <br>
POUT<POUT_LOW_THRESHOLD motherboard is considered OFF.<br>
POUT>POUT_HIGH_THRESHOLD motherboard is considered ON.<br><br>
The second detection mode is by measuring the +5VUSB signal. Usually motherboards turn OFF the +5VUSB signal when they are OFF.<br>
In order to enable this feature CONFIG1.b5 must be set to 1.<br><br>
If CONFIG1.b4 set, the PSU can shut down the OS by sending a Power Button event on USB.

==Software manual==
===Windows OS built-in support===
The DCDC-NUC implements one generic USB class (USB HID), therefore most of the
operating systems are recognizing it without any additional driver installation.
===Configuration Software===
The configuration software provides interface for DCDC-NUC monitoring, logging and setup.
It's recommended to be used by users with deeper understanding of the DCDC-NUC hardware since permits setting voltages, currents and other parameters which can be
dangerous if they are set without precaution.<br />
The configuration software has two main screens (Status and Settings) and a header with the important voltage/current values.<br />

====The first main screen is the "Status"====
Example of this screen is shown in the next image:<br />
<div style="display: inline; float: left;">
[[File:DCDC-NUC-Status.JPG‎|x350px|thumb|left|Status screen]]
</div>

The title bar shows the connection status, the firmware version and the mode of the DCDC-NUC. Example: "DCDC-NUC Connected v1.0 Mode: Dumb"

The header of the status screen contains:
:VIn: Input Voltage
:VOut: Output Voltage
:VThump: Thump Voltage
:IIn: Input Current
:IOut: Output Current
:Temp: Temperature
:VIgn: Ignition Voltage
:POut: Output Power

The "Status" screen contains extended information about the current state of the DCDC-NUC like internal state machine, voltages, currents, temperature, different read only state flags.
The user also have the possibility to log the current state into a *.csv file in the "Log" section.
The "Debug" section is for debug/support and can change between different firmware versions.
<div style="clear: both;"></div>

====The second main screen is the "Settings"====
Example of this screen is shown in the next image:<br />
<div style="display: inline; float: left;">
[[File:DCDC-NUC-Settings.JPG‎|x350px|thumb|left|Settings screen]]
</div>

This screen contains two main sections: the individual parameter setup for experienced users and the parameter save/load into/from file section.

The main section of the "Settings" screen is the individual parameter settings.<br>
This is recommended to be done only by experienced users. Any parameter of the DCDC-NUC can be set from here.

Changing one parameter is simple:
:- select the desired parameter from the "Parameter" list (simple click to select, double-click to edit). Below the parameter list a helper text is displayed (same from this manual).
:- after double click introduce the new value in the new popup dialog and press OK
:- the introduced value is checked - if something is wrong (out of limit, bad value etc.) error message will be shown
:- the ! sign will blink on the "Sync all parameters to the DCDC-Nuc" button to show edited but not saved/synced variables
:- after You have done with all parameter setting press the "Sync all parameters to the DCDC-Nuc" button to send all values to the DCDC-Nuc. IMPORTANT: without this step the new values will be lost, nothing is sent to the DCDC-NUC!

IMPORTANT: any parameter setting is taken into account by the DCDC-NUC in this cases:
: - after a full restart either with power cut from all sources (usb, vin)
: - hitting the "Restart DCDC-Nuc" button
: - keeping the "Reload parameters on the fly after sync" checked.
Do any parameter change with precaution, check the parameters and wires before applying it!

For users who need to setup more devices with the same DCDC-NUC settings, it is recommended to use the save/load parameters buttons.
The "Parameters: DCDC-Nuc ===> File (settings.ini)" button loads a full configuration from the DCDC-Nuc and saves it to the settings.ini file. You can disconnect
the current DCDC-Nuc from the USB and insert a new one, than press the "Parameters: DCDC-Nuc <=== File (settings.ini)" button to send the last saved configuration into the new DCDC-Nuc.

The "Parameters: DCDC-Nuc ===> CSV File (settings.csv)" button loads all parameters from the connected DCDC-NUC and saves it into a csv file. This type of file can be opened by any spreadsheet editor (OpenOffice, Microsoft Excel etc.) and contains the full set of parameters in human readable form.

The "Switch to bootloader" button is intended to be used for firmware updates. After You press this button the DCDC-NUC will disconnect, it will switch to bootloader mode and firmware can be updated as described [[DCDC-NUC#Bootloader_Mode|here]]

Every save/load/sync operation on the "Settings" screen affects the progress bar and the status bar on the bottom of the screen (labelled with "State:"). In rare cases You
might get error here with "try again" message. This happens in case of one parameter byte get's corrupted or timeout occurs during USB communication and/or DCDC-NUC flashing
operation. Please try again and contact our support team only if the device gives this error 4-5 times in a row.

===Windows System monitor===
The system monitor is a tray bar software which shows the current state on the tray bar icon and a semi transparent "always on top" capable small window.<br>
The popup window can be moved anywhere on the screen and can be customized. Our current setup has two skins but any combination is possible playing with the
"skin*.mbs" files installed together with this application. The current skin can be selected right clicking on the try icon.
The "skin*.mbs" files are simple text ones editable with any text editor (notepad for example).<br>
Adding a new skin is pretty simple – make a skin1.mbs (use the existing skin0.mbs for starting content) and start playing with the values from the new
file.<br>
The values are self explanatory – skin name, background image files, font descriptions and label/value pair coordinates for all the important DCDC-NUC values.
The size of the popup is defined by the background image – transparent parts can be defined as well (see for example: "bubble1.bmp").
Example screenshots:<br />
