BIOS Updates

Make sure your system’s drivers are installed and up-to-date.

This model uses the new Intel GPY115/EC1000S Ethernet controller provided by the Elkhart Lake platform. Some operating systems are not compatible, or require additional setup by the user for this Ethernet controller. *For systems purchased before March 1st 2023, Ubuntu can be installed after the Ethernet firmware has been updated. Customers interested in this can contact OnLogic Tech Support to RMA the system for this update.

The Helix 300 and 310 systems offer optional CAN bus and isolated Digital IO 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 (), but can be sent messages over the system’s Host Embedded Controller Interface (or HECI). The OS is transparent to the user. This interface may be used to send and receive CAN messages alongside setting and reading the Digital IO.

Requirements: An HX300 or HX310 with Windows and the latest HECI driver. The HECI Windows driver is provided and supported by Intel, and will be preinstalled on HX300 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.

1. Download the HX300’s .

2. Open a command window, and navigate to the location of the downloaded file.

   1. Press the Windows Key + R

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 the . The HX300 series utilizes the MOD106 DIO, however the PSE controls are the same for both parts and both are opto-isolated modules so this guide can be used for both.

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:

Input Impedance

Each digital input has a 10K internal pullup and a 10K series resistor.

The TM260 (the HX330 with ThinManager Ready firmware) is compatible with ThinManager 11 or higher. Customers interested in the ThinManager WiFi Boot option should use ThinManager 13.2 to enable this feature. Checkout our with more info about ThinManager WiFi Boot.

The TM260 requires version 14 of the Terminal Capability Database (TermCap) in order to properly download the firmware it needs to function. Customers can follow this to perform this update for their systems.

As with other newer model systems, this model includes a firmware TPM by default. It functions similarly to a TPM 2.0 module. If the optional dedicated TPM 2.0 module is added to the system, the firmware TPM will need to be disabled to allow it to function.

The firmware TPM can be disabled in the BIOS:

1. Power on the system and press Del to enter the Front Page menu.

2. Select Setup Utility.

3. Navigate to the Advanced tab and open Chipset Configuration.

The dedicated TPM should now be functional and detectable in TPM.MSC or Device Manager.
