Connection diagram DuoFlex CI

Insert CA module

Insert the SmartCard of your PayTV provider into the CA module (CAM) and then slide the CAM into a free CI slot of the CI. The pressure is slightly increased shortly before the stop when the CAM is plugged in correctly. After the position is reached, the CAM can be pushed for approximately another 5mm into the CI.

CA modules can also be plugged in or unplugged during operation. Detection is done automatically without the need of restarting the PC.

Up to two CA-modules can be used.
insert cam

DuoFlex CI wiring

The DuoFlex CI can be used with all Digital Devices cards of the Cine series (V 6.x or higher) or Octopus series.

A connection to a Cine series V5.5 - PCIe Bridge - mini PCIe Bridge is possible, however only the first CI slot can be utilized.

Two free ports on your Octopus or Cine series are required to use both CI slots. Connect the TAB 1 of your DuoFlex CI to the next available TAB on your Cine or Octopus card. TAB 2 on your DuoFlex CI is not functioning independently and therefore always requires the next higher TAB on the same Octopus or Cine card.

There is no need to connect both data cables to a Cine or Octopus series. In case of too few available expansion connections or if both CI slots are not required, one connected data cable is sufficient to operate only one CI slot. You can then connect the TAB1 to any free port on your Cine or Octopus series.

Notes on data connection

If multiple modules are utilized, connected tuner modules are identified in the system as follows, depending on the TAB used:
  • TAB 1 to Octopus series -> Tuner 1 & 2
  • TAB 2 to Cine or Octopus series -> Tuner 3 & 4
  • TAB 3 to Cine or Octopus series -> Tuner 5 & 6
Make sure that tuner extension modules are connected to smaller TABs of the Cine or Octopus series in terms of numeration than the DuoFlex CI.

Power connectors

The DuoFlex CI is equipped with 2 power connectors. Supply one of these two power connectors with a power cable. Depending on the housing or position of the CI, it may be beneficial to install the plug vertically or horizontally.

Both CI slots are always supplied by a single power connector.

Abb. Technische Zeichnung DuoFlex CI


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.

Expansion options Cine S2

Various combinations of Digital Devices DVB components with a Cine TV card are possible. (A maximum of 3 can be connected in version 7).

Slot brackets, assembly

Accessories for various combinations are available and can be obtained from Digital Devices.

The following figure illustrates examples of slot brackets and power connections.

Sample configuration shown: Digital Devices Cine S2 v7 with a DuoFlex S2 v4 expansion module on a combined slot bracket K (available as accessory)


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.

Testing and troubleshooting for using expansion modules (Tuner, CI)

  • Is your expansion module powered (connected to power supply or to the card)?
  • Is the data cable between the base card and the expansion module properly connected?
  • Is the module displayed in the DD Control Center?
  • Is the signal input of your module connected correctly (does not apply to CI modules)?
