Please read the following safety instructions carefully to avoid damage to persons or the product during use. Also obey the instructions in your PC manual.

Please provide the manual to people who carry out an upgrade or upgrade (also in case of resale).

Important safety instructions

  • Installation requires knowledge with PC systems and may only be carried out by experienced users and trained staff.
  • Never allow children to play with electrical appliances. They can not recognize hazards.

Disconnect your PC from the power supply before doing any work, and then wait a few minutes for all components to cool down before performing any work. There is a risk of electric shock when connecting to the power supply, which can be fatal.

  • The power plug must be accessible in order to allow disconnection from the power supply in case of danger.
  • Never bridge connections in the system or the power supply fuse, as there is a risk of electric shock.

Hazard information to work on your PC

  • Do not plug or unplug any cables when the PC is switched on (not even the antenna cable).
  • You should statically discharge prior to any work, for example by touching a grounded object.
  • Use only components and cables in perfect original condition. Defective devices and cables must be replaced.
  • Use the card only at the intended connections (PCI Express or data port) and do not apply force during installation
  • The card / module must not come into contact with moisture or chemical solvents. Cards / modules which come into contact with liquid are to be sorted out.

For certain functions (adjusting driver settings) it may be necessary to run the application as an administrator.


Connected hardware is displayed under Devices. For each base card, a menu item is created for selection.

If the card is equipped with expansion ports, those are displayed in the main screen, as well as the DuoFlex modules connected to them.

For diagnostic purposes, hardware data is available, which is presented in greater detail within the Diagnostics + maintenance section.

If installed cards or modules are not displayed properly, it must be checked whether they are connected correctly or not.

Signal setupDVB-S2

Digital Devices cards and modules can be configured for Unicable® reception according to EN50494 and EN50607. The device is set up in the Tasks menu under Unicable® reception (DVB-S/S2)

(Exception: Cards from the Max series, for which this option is located in the menu _Devices)_

Note: Different names for Unicable® and Unicable IIÆ may include: JessÆ Single Cable Routing (SCR) or single cable solution.*

  • Option normal operating state when using a standard SAT system / cabling. There are no other options available.
  • Option Unicable ® system according to DIN 50494/50607 when using a Unicable® receiving instalation.

The corresponding manufacturer of the LNB or multiswitch can be selected in the upper drop-down box. Then the model can be selected in the lower drop-down box.

If the existing model is not listed, alternatively another can be selected if it uses identical frequencies and is not PIN-protected.

When the selection is done, all tuners that can be configured for Unicable® reception are displayed under Tuner. Slot assigns frequencies to individual tuners.

Edit SCIF Devices offers the possibility to create a specific entry, which is then destined for manufacturer and model selection.

Pin Protected

If the Unicable ® multiswitch / LNB features a Pin Protected function, the option is displayed in the Digital Devices Control Center.These PINs must be entered at the corresponding ports in the Control Center.Usually the PIN specifications are defined by the LNB or multi-switch and can be found in the operations manual.

Note: If the function is activated, the devices exchange a PIN with each other so that no frequencies are used that are not intended for the respective receiver.

Signal setup DVB-C/DVB-T

Setting up reception mode(s)

By activating the checkboxes you can specify which type of reception is used and which type of tuner is displayed in the applications (for example "DVB-C").

Possible selections:- DVB-T- DVB-T2- DVB-C/C2- DVB-C/C2 WMC: (identifies tuner as DVB-S/S2 for use in the WindowsÆ Media Center)- ISDB-TSeveral options can be assigned to tuners for alternating use of different programs.

In the applications, all assigned tuners are displayed as a separate entry.

For example: Four tuners are assigned to DVB-C and DVB-T2. They are displayed four times as DVB-tuner in applications and four times as DVB-T2 tuner. Simultaneous usage is limited by the actual number of tuners, because multiple assignments do not increase the total number of tuners.

Sample application: Alternating utilization of the tuner in DVBViewerÆ (option "DVB-C/C2") and WindowsÆ Media Center (options DVB-C/C2 WMC).

Accessing a tuner that is already in use by another program is not possible. Depending on the application, there may appear messages like "no device available“.

Digital Devices TV cards and modules can be expanded and combined easily thanks to the modular design of Digital Devices solutions.

Each DuoFlex module can be connected to any TV card or bridge via an expansion connector.

Even cards without expansion connectors can be integrated since the PCIe system bus is able to establish a connection.

In either case additional modules are seamlessly integrated into the Digital Devices Control Center.

Utilization of a Common Interface module with the Max M4/S8/SX8/A8

The Digital Devices Max DVB card can also incorporate a Digital Devices CI module.

The following CIs are approved:

  • Digital Devices Octopus Single CI (1x CI Slot)
  • Digital Devices Octopus Twin CI (2x CI Slot)

The CI requires an additional PCIe slot.

Note: Digital Devices Max M4/S8/SX8/A8 TV cards are equipped with a 20 pin header. This port is not designed for connecting expansion modules such as the Digital Devices Flex CI or Digital Devices DuoFlex Tuner expansion modules.

Exclusively for WindowsÆ a CI module MTD feature is offered, however limited to 4 tuners per CI slot for the Max series (M4/S8/SX8/A8).


Please consider the following advice, once a problem regarding your card occurs. Please access our knowledge base for more information and assistance at:

Basic prerequisites / testing for errors

Turn off the PC and disconnect the power cord before carrying out any checks.

Now perform the following checks:

  • Are all cables and connectors properly connected?
  • Is the card firmly plugged into the PCIe slot?
  • If the card is not recognized by the system, please try another PCI Express slot. Since some motherboards don't recognize cards plugged into a PCIe X16 slot properly. Utilizing the X4 or X1 slot should be considered.
  • Make sure using original equipment only. Do not interchange cables from different devices, even though they appear identical. They may differ in pin configuration.
  • Does the antenna provide adequate antenna power?
  • Make sure to implement a minimum distance of one meter to high-frequency and magnetic interference sources (TV set, mobile phone, speaker boxes, etc.).
  • Turn the PC back on and carry out the following checks:
  • Does the card show up in the device manager or in case of a Windows PC in the Digital Devices control Center?
  • Inside BIOS, "PCI Express overclocking" should be set to 100 and not into "auto" mode.
  • Does the DD Control Center or your application display a signal?
  • Does the problem occur in one application only? Try it out in Digital Devices TV as well.
  • Is the installed driver up-to-date? Does the problem still occur when a different one is used?
  • Did you install the required codecs for playback on your system? Disable DXVA if block graphics occur with HD stations.

SAT-specific tests:

  • Does your LNB need to be powered?

Note: No additional power supply is required if the connected LNB is powered by a multiswitch or if the LNB does not consume more than 5 watts (see manual of the LNB). In case of the Cine S2, an additional power supply via Sherlock connector is possible to supply LNBs with up to 20 watts

  • Are the DiSEqC settings correctly configured for the specific card?
  • Is either a digital or a universal-LNB / LNC present?
  • If Unicable is used, check the frequency allocation within DD Control Center

DVB-C-Spezific test

Is a signal detectable at the connector and is the signal unencrypted? Many provider utilize basic encryption, which makes a CI module with CAM mandatory for many stations.


  • Can you watch the channels with other devices?
  • Can you watch the television program of public broadcasters, which tend to be transmitted without encryption.
