  • For analog audio, use a USB-C digital-to-analog audio cable, such as "inLine 33054C" audio adapter cable.
  • The player does not support 3G/4G USB cellular modem.

Blue button

The player's blue button is multi-functional allowing to perform different operations depending on how long it is pressed and whether the player is powered on or powered off during that time - like trigger OSD information, shut down, reset to factory default settings, force Recovery mode, etc.

See Blue button page for more details.


The player has four diagnostic LEDs on the front side indicating power, system, Wi-Fi and network. Two more are integrated within the network connector on the back side. These LEDs can be used to quickly assert the status of the player.

See LED page for more details.

Enclosure / casing


The player can be mounted using two M5 bolts - see the technical drawing above for exact coordinates of the mounting holes.

  • If the mounting surface is itself well ventilated and/or will help with heat dissipation (e.g. a separate bracket of a display mount) then the player can be mounted flush with the surface, but you should monitor the temperature during use.
  • If the mounting surface is attached to another heat source (e.g. the back panel of a display) then you should use standoffs to allow air to circulate around the player, and monitor the temperature closely.


Each HMP400 player has a unique serial number and a MAC address. Each player has also a device name, set by default to the player serial number, displayed and configurable within the HMP Control Center interface.

A sticker with the serial number, barcode, player model and few other information can be found on the bottom side of each player. This helps to identify the unit and it should not be removed.

Logo and printing

  • Situations may arise where labels or transfers may need to be applied to the player. This is generally not recommended by SpinetiX as the heat generation of the device may be affected.
  • There is almost no risk of a sticker or label removing the logo printed on the player; the printing process used is a special type which results in ink being protected by the outside layer of aluminum itself.
  • Any material affixed to the player must be entirely removable without a trace for the unit to remain within warranty.


The player can be powered over Ethernet (PoE+ / 802.3at) or by using an external USB-C power supply (power delivery 2.0, 27W, min 3A@9V) - although both are supported, it is recommended to use one method or the other.

The typical power consumption of the player, measured in normal conditions is 9W; the maximum is 14W, excluding USB port loads.

External power supply

HMP400 external power supply
  • Model: USBC-PD-30
  • Input: 100-240V 50-60Hz.
  • Output: 5V3A / 9V3A / 12V2.5A
  • DC cord: 150 cm
  • Plug: the power supply unit comes with a built-in type A plug and a removable type C plug.
  • The USB-C connector attached to the PSU must be connected to the USB-C port (marked with the DC symbol ) next to the HDMI port. See how to connect the external power supply.
Incorrect use of a power supply or using an incorrectly rated power supply can damage your player and void the warranty.

Power over Ethernet

The player implements the IEEE 802.3at-2009 PoE standard, also known as PoE+ or PoE plus.

  • The power comes from a power supply within a PoE-enabled networking device (such as an Ethernet switch) or can be injected into a cable run with a midspan power supply (PoE power injector) that can be used in combination with a non-PoE switch.
  • The maximum power delivered by the power sourcing equipment (PSE) is 30 W, while the power available at the powered device (the player) can be as low as 25.5 W, depending on the length of the cable. The standard requires Cat 5 cable or better for high power levels.
  • When the player is rendering complex content, it can use up to 14W, which means that not all 3 USB ports can be used at full load (4.5W), but that's usually not needed anyway, as USB devices typically use much less than the 4.5W max of the standard (USB2 devices, like keyboards and touchscreens are limited to 2.5W for example). On the player side, a microcontroller will automatically shut down USB ports if devices are drawing too much in order to avoid a shutdown of the player by the PoE Ethernet switch.
  • When deciding what model of PoE switch to use for powering multiple players, you should consider a power budget of 30W per player to avoid any issues.

Power off

See how to correctly power off the HMP.


SpinetiX offers 3 years of Hardware Limited Warranty for HMP400 products.

  • A 5-year warranty extension can be purchased separately.
  • The player has a very low probability of failure because its hardware architecture is free of moving parts. There is no official mean time between failures calculated; the component with the shortest MBTF is currently the internal storage, however, the high-quality cards used by SpinetiX are certified for at least 5 years of use by the manufacturer.
  • The warranty does not apply to the external power supply unit, nor the internal memory medium (storage). See General Terms & Conditions of Sale (Exclusions section) for more details.


Operating System

The embedded DSOS™ is a secured operating system designed for digital signage players, especially for demands of defense, financial, cruise vessel and other high-availability scenarios. It cannot be changed in any way and no other OS can be installed on the player.

DSOS activation licenses

The HMP400 works out of the box with SpinetiX ARYA cloud-based service. More features can be unlocked by purchasing and activating a DSOS license - you can choose between WIDGETS, KIOSK, or SYSTEMS.

HMP400 activation licenses
In WIDGETS mode, you combine the power of the HMP400 and the versatility of Elementi and its 250+ widgets. Fill any display with content that auto-updates using data from your everyday tools like social media, G-Suite, or Microsoft Office 365. Widgets are easily customizable, simple, and powerful to deliver information. This license activates all APIs for content automation and distribution.
The KIOSK mode builds on top of the Widgets mode and offers support for rich interactive content created with HTML5 and/or Elementi, including HTML5 dashboards, Microsoft Power BI, Google Maps, YouTube, Vimeo, etc. This license activates native support for HTML5 and physical input/output APIs.
The SYSTEMS mode allows you to immerse audiences with your story through IoT solutions and third-party technologies. With sensors, cameras, smart-building, queue management systems and more, you have the full integration capacity of the HMP400 to deliver experiences with an unlimited degree of personalization. This license activates all SpinetiX features and APIs for maximum integration options, such as multiscreen synchronization/video wall, custom resolution, streaming, network triggers from external devices or applications, etc.

Activate a DSOS license

Once you have purchased a DSOS license, follow these steps to activate it on your player:

  1. Open in your browser.
  2. Sign in to your account.
    • If don't have one, but you already have an account on SpinetiX ARYA™, you can use that one to log in with, as the two platforms share the users' database. Otherwise, sign up for a new user account using your email address (the SpinetiX logo button) or your Google or Facebook profile.
  3. In the top part of the screen, enter the player' serial number and the license code (12 alpha-numeric characters).
  4. Click the "ASSIGN" button.
    • A line containing the serial number and the DSOS license type is added underneath.
  5. If you want to assign a label, click on the "LABEL" field, enter the text you want, and then press the "Enter" key.

Modify a DSOS license

To remove a license from a player and/or add it onto another player, follow these steps:

  1. Click the "MODIFY" button on the corresponding line.
  2. Delete the serial number. This will remove the license from that player.
  3. Enter the serial number of the new player. This will assign the DSOS license to the new player.
  4. Press the "Enter" key to save the changes.
