The Helix platform supports an optional Isolated Digital I/O add-in card (OnLogic ADP120). This option allows for integration of the Helix platform with existing PLC integrations or other digital logic applications. For a complete explanation of features, operating voltages, and safety information, please refer to the DIO expansion manual on the OnLogic support site.

The HX401 with optional CAN installed. Additionally, the DC power barrel and terminal block power input options are both shown.

Mainboard power is applied to the Helix platform by way of a female barrel jack connector (OD: 5.5mm ID: 2.5mm. 12mm length ). The system is operational from 19V~24V. The maximum rated current of the connector is 7A. Use a wire gauge that is rated for the operational current. See below for on-board connector pinout.

Note: Located above the power barrel is a sheet metal punch-out for the plastic cable retention clamp. To use this feature the sheet metal tab needs to be removed with the backplate uninstalled to ensure the tab does not break off into the system.

Helix utilizes Intel’s Integrated Gen 12 processor graphics that power the onboard DisplayPorts 1.4a. This means resolutions up to 4096x2160 @ 60Hz are supported on both outputs simultaneously. All ports support Multi-Stream Transport (MST).

The Intel I219 LAN Port on Helix supports up to 1Gbps link speeds over standard shielded CAT5e or CAT6 cables. The connector is the industry standard RJ45 connector. This port also features Intel’s vPro(R) technology enabling remote out-of-band management and security features (requires Intel Core i5 or higher). The LAN link state is shown by the two LEDs enclosed in the port. The description is included below.

The second LAN Port on Helix supports up to 1Gbps link speeds over standard shielded CAT5e or CAT6 cables. The connector is the industry standard RJ45 connector. The LAN link state is shown by the two LEDs enclosed in the port. The description is included below.

The serial port mode and voltage between Off/5V on Pin 9 on Helix can be selected in the BIOS configuration. The serial ports support RS-232, RS-422, and RS-485 configurations. Refer to the for configuration instructions.

The CAN port on Helix 401 supports CAN2.0 A/B at baud rates from 100-1000 kbaud. The system CAN port is not internally terminated, and a properly terminated (120 Ohms, typical) cable should be used. The communication protocol used to send and receive messages is detailed in the section.

If the terminal block power option is selected, mainboard power is applied to the Helix platform through a 4-pin terminal block connector (Mating part: Dinkle #2ESDVM-04P-BK or equivalent).

The system is operational from 12V~24V (HX401) [see section 4.3 for input voltage qualifications]. The maximum rated current of the connector is 15A per pin. Use a wire gauge that is rated for the operational current. Cables should be properly terminated with wire ferrules. Do not use the terminal block with tinned wire ends or solid core wire. See below for the connector pinout which is also indicated on the terminal block mounting panel adjacent to the connector. Installation of DC Mains connection shall only be performed by skilled personnel and in accordance with your local and national electrical code (Example: NEC, CEC).

When using the remote switch connections with the terminal block option, mating power switch cables should be a twisted-pair wire with floating shield to assure proper immunity to EMI/RFI. It is recommended to keep wires at less than 3 meters in length. Switches should be momentary contact type only.

These serial ports support RS-232, RS-422 Full-Duplex, and RS-485 half-Duplex configurations. The serial port communication mode can be selected in the BIOS configuration. In addition, 5V power can be enabled on pin 9 in the same BIOS menu. Pin 9 is rated to provide 150mA of current. Refer to the for configuration instructions.

If the BIOS needs to be updated, please refer to the for reflashing instructions.

A 2.54mm pin header and jumpers are used to clear the CMOS settings of the Helix platform.

The system CMOS settings can be cleared with the pin jumper. To clear the CMOS the following steps shall be followed:

1. Disconnect system power.

2. Place jumper in the “clear” position.

3. Wait 10 seconds.

4. Remove jumper from the “clear” position and return to default position

The RTC battery on the Helix platform is used to retain BIOS CMOS settings and maintain the real-time clock for the system. If the RTC battery is low, CMOS settings will not be retained and you may receive an alert in the operating system. The cabled RTC battery should be replaced with a Maxell CR2032-WK11 (or UL listed equivalent). An equivalent battery shall use a Hirose DF13-2S-1.25c connector to mate with the on-board connector.

The on-board USB 2.0 header provides a single USB 2.0 signal. It utilizes a WR-WTB 4-pin 1.25mm pitch male pin connector with the pin configuration in the chart below. The 5V power pin (Pin 1) can provide up to 1A of current.

Mainboard power can be applied to the Helix platform by way of OnLogic ADP124 Power Terminal Card. The system is operational from 12V~24V. The maximum rated current of the connector is 3A per pin with a pitch of 2.54mm. Use the OnLogic ADP124 Power Terminal Card with validated functionality and the operational current. See below for connector pinout.

Four Gen12 CPU options are available for the HX401.

The power consumption of the HX401 system was measured for various system configurations, workloads, and power states at both 12V and 24V system input voltages. Tests were performed using BurnInTest v9.0 build 1012 to stress system components with and without graphics enabled. The build configurations and power consumption are listed in the tables below.

*The configurations below are using representative samples of internal devices, the specific components mentioned below may vary from the devices provided by OnLogic. The power consumption for each system configuration is record below

These DC levels specified are the absolute max values for the pins for function and safety of the system. The protection circuitry allows for brief transient voltages above these levels without the system turning off or being damaged. A transient voltage suppressor on the power input allows momentary excursions above stated limits. For input power consumption and current see Power Consumption

The Helix platform supports multiple power states. The wake-up events can be configured in the BIOS. This section describes the supported power management functions and gives information on protection circuitry for power adapters. Low power shutdown is an additional option in the BIOS. See for more information.

How do I Enable/Disable auto power on?

Enter the BIOS by pressing Delete while the system is booting, then navigate to Advanced > PCH-IO Configuration > State After G3 Select S0 to enable auto power on Select S5 to disable auto power on

An optional CAN add-in card is available. The add-in card has an NXP i.MX1050-series microcontroller that can communicate with the host processor over USB. The card provides an interactive shell for configuration on a virtual COM port, and two CAN interfaces accessible through two additional virtual COM ports.

The following repository, , demonstrates how to use the CAN bus on I.MX RT1052 based, CAN 2.0 A/B-enabled, OnLogic CAN Add-in Cards. It includes detailed instructions on how to setup and program the interface using an included Python CAN utitilty (Linux or Windows) and Bash shell commands (Linux).

The following repository, , demonstrates how to use the CAN bus on I.MX RT1052 based, CAN 2.0 A/B-enabled, OnLogic CAN Add-in Cards. It includes detailed instructions on how to setup and program the interface using an included Python CAN utitilty (Linux or Windows) and Bash shell commands (Linux).

The add-in card is configured interactively through its shell using a serial terminal emulator program. The shell is accessed differently depending on operating system.

To access the shell on Windows:

1. Open Device Manager by pressing Win+X M. Open the “Ports (COM & LPT)” menu.

2. Note the “COM#” numbers on each port listed. The shell is typically the lowest-numbered “USB Serial Device” port. The first and second CAN interfaces typically have higher port numbers.

3. Download and install PuTTY from the link above.

To access the shell on Linux:

1. Install picocom, e.g. “sudo apt install picocom” on Ubuntu.

2. Open the shell’s virtual COM port with picocom by running “picocom /dev/serial/by-id/usb-OnLogic_USB-CAN-*-if00”.

3. Some Linux distributions may not configure udev to produce by-id links. If those links are missing, try /dev/ttyACM0 and similar devices.

Once the shell is open, type “help” for usage information.

On Linux, the slcand utility can configure the add-in card’s interfaces as a regular SocketCAN network interface. Make sure the interface is configured for slcan usage by entering “set can-mode VCAN1 slcan” (and similar for “VCAN2”) in the shell.

On most Linux distributions, slcand is part of a package called can-utils; on Ubuntu, it can be installed with “sudo apt install can-utils”. Once installed, start the utility by running e.g. “slcand -oc -s6 /dev/serial/by-id/usb-OnLogic_USB-CAN-*-if02 slcan0” to create a SocketCAN interface named slcan0 running at 500k (“-s6”) from the first CAN interface’s virtual COM port.

The slcan message format is widely supported. High-quality libraries are available for most programming languages that handle the details of the protocol. It can also be implemented manually if needed.

The slcan protocol is stateful; each interface needs to be configured and opened before it can be used, and must be closed before it can be reconfigured. Make sure the interface is configured for slcan usage by entering “set can-mode VCAN1 slcan” (and similar for “VCAN2”) in the shell.

Each CAN interface has a corresponding virtual COM port. Commands are sent on that port to configure the interface and send frames. Each command consists of an ASCII letter, optionally followed by other ASCII text, ending with a newline (“\n”) character.

The interface baudrate is set with the “S” command. Nine baudrates are supported:

Once the baudrate is set, the interface should be opened by sending the open command (“O\n”). Once open, frames can be sent to the microcontoller in the format documented in . As frames arrive, the microcontroller will send messages back on the virtual COM port. To stop it, close the interface with the close (“C\n”) command.

Alternate CAN Format

The legacy “std” message format is supported for backwards compatibility with other devices, but is not recommended for new development. The standard slcan format should be used instead due to the availability of high-quality tools and libraries for working with that message format in most programming languages.

An optional DIO add-in card is also available. The add-in card has an NXP i.MX1050-series microcontroller that can communicate with the host processor over USB. The card provides an interactive shell for configuration on a virtual COM port.

BIOS Version 1.51

1 - Getting Started

1.1 - Introduction

The UEFI BIOS is a small program which runs when your computer starts and configures its basic functions. That configuration is automatic, and most users will be satisfied with the default configuration. If the default configuration is not sufficient, the BIOS has setup menus which can be used to reconfigure the computer.

The purpose of this manual is to document the function of the BIOS and its available configuration options. The text of this document lists the BIOS menus and options exactly as they appear in the BIOS menus: in the correct order, with the correct default values for this BIOS version. Some options are hidden based on how other options are set and which hardware is detected in the system, so some options may not appear on all systems. Informative screenshots are also provided throughout, but their contents may not exactly match this BIOS version.

1.2 - Navigating the Setup Menu

To access the BIOS setup menu, hold the Delete key on the keyboard while turning on the system. After a few seconds, the BIOS front page menu is shown:

On each menu, the selected option is shown in white, other options are shown in blue, and read-only options are shown in gray. Some menus have multiple screens, which are shown at the top of the screen. The active screen is shown with a gray background and inactive screens are shown with blue backgrounds.

BIOS menus are navigated by pressing keys on the keyboard:

• F1 shows help on available keyboard shortcuts

• ↑/↓ arrow keys select the option above or below the currently-selected option

• →/← arrow keys activate the screen to the right or left of the currently-activated screen

Several options are available on the front page:

• Continue: continues the boot process normally, booting the installed operating system

• Boot Manager: opens a menu to select which device should be booted

• Device Management: opens a menu which shows the status of the system hardware

The boot manager menu shows the devices available to be booted. The installed operating system and any attached USB drives will be listed. If enabled in the setup utility, the UEFI shell is also listed. Selecting an option boots it.

The setup utility shows the status of the system and allows many configuration options to be changed. These options affect the functionality, stability and security of the system, and should not be changed without an understanding of their meaning.

The setup utility has many screens. Press the →/← arrow keys to select between them.

Several configuration options are frequently used.

Default value: S0 State; possible values: S0 State, S5 State

Controls the state the system enters after G3 (power loss). If set to S5, the system remains off when initially connected to power. If set to S0, the system boots when connected to power.

Default value: Enabled; possible values: Enabled, Disabled
