Frequently Asked Questions (FAQ)

Enabling Auto Power on

The system can be configured to turn on automatically when DC power is connected. This is useful for power outage recovery or if the unit is mounted in a hard to reach location. You can enable Auto Power On by following the steps listed below.

• Power on the system and immediately press the Del key a few times until you see the “Front Page” menu
• Arrow down and choose “Setup Utility” by pressing enter

• Under the advanced tab, open the “RC Advanced Menu”

• Open the “PCH-IO Configuration” menu

• The auto power on setting is called “State After G3”.
• Set it to S0 State to enable auto power on
• Set it to S5 State to disable auto power on

• Press F10 to save and exit. Then you are all set.

Disassembly Guide

Opening the system does not void the warranty, however, some precautions are necessary to avoid damaging the unit. Any damaged caused will not be covered by warranty.

• Perform this disassembly in an area free of static discharge
• Before beginning, touch a grounded metal surface to discharge your body of static electricity

• The internals of the system are now accessible.

Troubleshooting

Clearing the CMOS

If the system fails to power on or output video, clearing the CMOS can often help. To clear the CMOS, the system needs to be opened and an internal switch needs to be pressed.

Opening the system does not void the warranty, however, some precautions are necessary to avoid damaging the unit. Any damaged caused will not be covered by warranty.

• Perform this disassembly in an area free of static discharge
• Before beginning, touch a grounded metal surface to discharge your body of static electricity

• Re-assemble the system. Do not over tighten the screws.
• Re-connect the system and power it on.
• Do not touch it for 2 minutes. Wait and see if it outputs video.
• If not, contact OnLogic tech support for an RMA using the button on the right sidebar. >

Windows Bluescreen after BIOS update

After updating to BIOS version A074 or later, Windows may display a Bluescreen error with message “SYSTEM_THREAD_EXCEPTION_NOT_HANDLED”. You will need to adjust the BIOS settings to make it work.
Go into the BIOS and change the following x2 options

1. Advanced -> Expert mode -> Enabled 
2. Advanced -> RC advanced menu -> PCH-IO Configuration -> PinCntrl Driver GPIO Scheme -> Disabled 

Press F10 to save the BIOS settings and reboot. If the OS is able to recover, it should boot up. If not, you may need to reinstall the Windows OS.

Ubuntu boots up slowly / doesn’t turn off completely

If you are having issues with Ubuntu randomly crashing, taking several minutes to boot up, or an issue with not fully turning off, try Enabling the PinCntrl Driver GPIO Scheme:

Automotive Ignition Timings

Feature Overview

The ignition sense feature can be used to turn the Karbon unit on and off with a vehicle’s ignition. It can also be used in non-automotive applications using a switch instead.

An example configuration is shown below for Windows. The switch connects positive DC power to the IGN pin. The unit will turn on when power is applied to the IGN pin, and turn off when power is removed. These events have configurable delays.

Enabling and controlling ignition sense

• Download the control application from the link above

• Once you have navigated to the directory that the HWC file is located, execute the following commands in order:

hwc ign set ignition-sense -v 1
hwc ign set low-power-mode -v 1
hwc ign set shutdown-timer -v 10
hwc ign set startup-timer -v 10
hwc ign set hard-off-timer -v 3000

• Power down the system and you can turn it back on by connecting positive power to the IGN pin. This will give you a basic ignition timings setup with 10 second delays. Reference the table below for customizations.

Ignition Sensing Commands

hwc ign set command -v value

hwc ign get command

Command	Description	Possible Values
ignition-sense	Enables or disables ignition sense	0=off, 1=on
low-power-mode	Reduces idle power consumption (recommended on when ignition sense is used)	0=off, 1=on
startup-timer	The delay between IGN power being applied and the unit turning on	1-2147483647 (seconds)
shutdown-timer	The delay before Windows is shut down when IGN power is cut	1-2147483647 (seconds)
hard-off-timer	After the shutdown timer has completed, power will be fully cut after X number of seconds. This is useful in case the system freezes at shutdown.	1-2147483647 (seconds)
low-voltage-timer	The low voltage shutdown can be delayed by X number of seconds. A value of at least 10 is recommended to avoid voltage drop related shutdowns – i.e. when the engine is started.	30-2147483647 (seconds)
shutdown-voltage	The unit can shut itself down when a certain low voltage threshold is reached. This helps prevent over discharging a battery. (1150 => 11.5V)	600-4700 (centi-volts)

DIO and CAN

The Karbon K410 and K430 series systems offer CAN bus and (optionally) isolated DIO (Digital Input/Output) support. This functionality is through the processor’s supporting ARM microcontroller, known as the Programmable Services Engine (PSE).

The PSE is isolated from the core processor, runs its own OS (Zephyr RTOS), but can be sent messages over the system’s Host Embedded Controller Interface (or HECI). The Zephyr OS is transparent to the user. This interface may be used to send and receive CAN messages alongside setting and reading the Digital IO. 

Note: Packages such as SocketCAN are not supported.

Quickstart

Requirements: A K410 or K430 with Windows and the latest HECI driver. The HECI Windows driver is provided and supported by Intel, and will be preinstalled on K410 units purchased with Windows. If Windows is installed by the user, the driver is included with our driver package linked at the top of this page.

Note: We recommend you update to the latest BIOS version for the best compatibility with this application.

1. Download the K410’s hardware control command line application.
2. Open a command window, and navigate to the location of the downloaded file.
   1. Press the Windows Key + R
   2. Type cmd.exe and hit Enter
   3. In the window that opens navigate to the download location:
      1. e.g.  cd C:\User\Username\Downloads
3. Display the built-in help text:
   1. hwc.exe --help

DIO Examples

The (optional) MOD110 digital input/output (DIO) expansion adds up to eight digital inputs and outputs to the system, and an additional CAN port. It also optionally provides support for pulse width modulation (PWM) on three of the eight digital output pins, and support for using a quadrature encoder peripheral (QEP) in place of the first and/or second group of three digital inputs.

See our dedicated DIO article on how to get started with theexpansion module, the MOD110.

Application Integration

See Using the K400 PSE with Ubuntu for information about C sample code and a reference on command packing and communication.

The HECI interface uses packed structures to send data between the host and PSE. Specific type structures are provided in the sample code, but an outline of the message format is available below:

Bits	Description
0 – 7	HECI Command Identifier: 0x01: System Information: 0x02: Digital IO 0x04: Can Bus
8	Set as ‘1’ if this message is a response from the PSE
9	Set as ‘1’ if this message contains a valid data body
10 – 25	Packed ‘argument’ for a given command. Format depends on the command identifier.
26 – 31	Status of last command
32 – 39	Data format of body: 0: Raw data 1: Version information 2: CAN message 4: DIO message 7: ASCII String
40 – 168	Body of message data, usually in the form of another packed structure.
