Before You Start

Supported Samsung EMDX Series Devices

The following Samsung EMDX Series Color E-Paper device is supported:

• EMDX-076D

Ensure your PADS4 Server is installed and configured before proceeding.

---

Minimum Requirements

PADS4 Server Version: 2025.1 or later

Ensure your server meets the minimum version requirement before proceeding with installation.

---

First-Time Setup

When you turn on the Samsung EMDX for the first time, a configuration wizard will start.

If the configuration wizard does not start, perform a factory reset before continuing.

---

Performing a Factory Reset

1. Step One

   Reset the device by holding the PAIRING and MODE keys for ~5 seconds, which are located on the back of the display.

   This process will take ~10 seconds to complete.

2. Step Two

   Afterwards, press the power button again, which will boot the display.

3. Step Three

   The device should now be reset and show new QR codes that can be scanned.

The device will restart and display the welcome screen / QR codes to scan for the mobile application.

---

Installing mobile application

Currently, you will need to use a mobile application to use the display, since this display does not support interactivity through other mediums. To download the latest version from the app store, scan the QR code on the display.

Set up the display

Once you have the mobile application, you can set up the display. Before you start, make sure you enable Bluetooth and Location on your mobile phone (Location can be disabled at the end of this process).

1. Step One

   Start the mobile application of Samsung on your mobile device.

2. Step Two

   Accept the required permissions.

3. Step Three

   Scan the QR code that is currently being displayed at the bottom of the screen.

4. Step Four

   Accept the request to connect the display via Bluetooth.

5. Step Five

   To set up the Wi-Fi connection on the display, you need to choose a connection that your mobile phone is also connected to (requires Location).

   Make sure you choose a connection that**_DOESN’T _** require account credentials (only Wi-Fi password allowed)

6. Step Six

   Accept the privacy agreement and choose “Manual Setup”

7. Step Seven

   Define a device pin and set the device orientation to landscape.

8. Step Eight

   Configure sleep mode to off.

9. Step Nine

   Turn off network standby and set device date & time to automatic.

10. Step Ten

    Set the daily refresher timer and set the content player to custom.

11. Step Eleven

    Now define a name for the device, and it will then show up under devices in the application.

Installing PADS4 Viewer

To install the PADS4 Viewer application, you need to define the server URL where the application is hosted. This works like other Samsung displays, but instead of doing it on the display directly, you need the mobile application.

1. Step One

   Start the mobile application of Samsung

2. Step Two

   Select the display you want to use

3. Step Three

   Under “Player type” at the bottom of the screen, make sure it is on “CustomApp”

If the display is sleeping, click the “Wake up” button (if that doesn’t work, you have to press the power button on the display).

1. Step Four

   Specify your PADS4 Server URL:

   http://<server>/PADS4/Apps/tizen/Epaper
   https://<server>/PADS4/Apps/tizen/Epaper
   

   Replace <server> with the IP address or domain name of your PADS4 Server.
   Ensure “PADS4” is in CAPITAL letters, or the connection will fail due to case sensitivity.

1. Step Five

   Click on “Install”

2. Step Six

   The display will now show the PADS4 logo after a minute with the viewer name and connection status and the bottom left of the screen.
