First, take out the HMP400 player from its box. There are no video or network cables inside the box. An external USB-C power supply can be purchased separately, if PoE is not available.

Note Note:
Before connecting the cables, it is recommended that all devices are unplugged from the power grid.
HMP400 input and output interfaces

Step 1: Connect the screen

The HMP400 can output the video signal over HDMI 2.0 (UHD) or DisplayPort 1.2 Alternate Mode over USB-C.


You need a display with an HDMI type A (female) connector and an HDMI cable (not included).

  1. Connect one end of the video cable to the HDMI port of your player.
  2. Connect the other end of the HDMI cable to the HDMI port of the display.
Note Note:
For UHD/4K resolution output, a (Premium/Ultra) High Speed HDMI cable is required.

You need a display with a DisplayPort receptacle, and a matching USB-C to DisplayPort cable (not included).

  1. Connect one end of the video cable to the second USB-C port of your player - the one marked with DP++ logo.
  2. Connect the other end of the cable to the DisplayPort receptacle of the display.

Step 2: Connect the network

To connect the player to the wired network, you need a standard RJ45 Ethernet cable (not included).

  1. Connect one end of the RJ45 cable to the Ethernet port of your player.
  2. Connect the other end of the Ethernet cable to a network port (female connector) of a network switch or a computer (direct connection).

Step 3: Connect the power

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.

For the PoE, make sure to connect the Ethernet cable to a PoE port of the switch and then switch on the screen.

For the external power supply, follow these steps:

  1. Connect the USB-C connector attached to the PSU to the USB-C port (marked with the DC symbol ) next to the HDMI port.
  2. Connect the PSU plug into a power outlet.
  3. Switch on the screen and the LAN-Switch or computer.


The player's LEDs should light up at this point, a sign that the player is receiving power and is starting the boot-up process. During the boot-up, a splash screen is shown on the screen, first at 640x480 resolution, then at the screen's resolution.

Once the player has finished booting up, the System LED should blink green and the screen will display something like this:

Note Notes:
  • If the Power LED doesn't light up at all, then there is a problem with the power supply. If PoE is used, make sure the Ethernet cable is good and connected to a PoE port of the switch. If the external USB-C power supply is used, try a working PSU from another SpinetiX player or switch to PoE instead.
  • If any of the LEDs turn red, with or without blinking, then there is a problem - see the LED page for more details.
  • If you cannot see anything on the screen, follow these troubleshooting steps.

Player setup


The HMP400 works out of the box with SpinetiX ARYA™ cloud-based service. A basic player setup can be made directly within ARYA:

  1. Open in a browser
  2. Log in with your user credentials. Or sign up if you do not have a user yet.
  3. From the right-side menu, select Players ⇾ Setup, then click the "ADD PLAYER" button on the right side of the page.
  4. Set the player name, the screen orientation, and the time zone.
  5. Wait for the player to reboot.
Note Note:
Once you add the player into ARYA, you can no longer access the Control Center for full player configuration. If that is needed, then you must remove the player from ARYA or do a reset to factory default settings using its blue button.


For a full configuration, before adding the player into ARYA, follow these steps:

  1. Briefly press the blue button to find the player addresses.
  2. Type any of the addresses shown on your screen in your browser’s address bar.
  3. Follow the instructions of the Configuration Wizard for the initial setup.
  4. Make any other changes you might need within Control Center and restart your player to apply those configuration settings.

DSOS license

If you have purchased a DSOS license for your HMP400 player, follow these steps to activate that license.
