# Configure SDI output

The Receiver service on MK.IO Beam can output uncompressed digital video, audio, and ancillary data
using the SDI output standards.

## Supported SDI Output Cards

SDI output on MK.IO Beam requires supported hardware option cards. See the **SDI Output**
section in the technical Reference documentation for a list of compatible cards.

## Configuring SDI Output

### Configuring ASI/SDI mode

To use the card as a SDI output card it must be configured as follows (see also [Set up SDI/ASI cards](/beam/system-admin/maintenance/setup-sdi-asi-card/)):

* Select  Appliance from the left-hand side menu.

* Click the ASI/SDI Interface tab.

* Select the Slot Tab corresponding to the SDI/ASI card. If more than one card is present,
  there will be a separate slot tab for each card.

* Select the appropriate ASI/SDI mode from the ASI/SDI Mode drop down menu. The description
  shows which SDI standards are supported (for example, UHD output may not be supported).

* Click the Apply and Reboot button.

* A confirmation pop-up window will appear asking, “Are you sure?”

* Review any warnings or guidance provided. If you are sure, click Yes, configure and REBOOT!
  Otherwise, click Cancel to abort.

* Following the reboot, refresh the web page. The reboot may take a few minutes to complete.

### Determine SDI output card Slot number

SDI port selection is referenced with its card slot number to differentiate where multiple cards are
fitted to the server. The card name/type for an assigned slot number can be determined using the
following steps:

* Select  Appliance from the left-hand side menu.

* Click the ASI/SDI Interface tab.

* Select the Slot Tab corresponding to the SDI/ASI card. If more than one card is present,
  there will be a separate slot tab for each card.

The selected Slot tab should list some useful data such as card model, serial number, etc.

There is a known issue on some servers where the reported slot number does not match the slot
number printed on the rear chassis.

### SDI output port

Before you start, ensure at least one Receiver service is configured.

* From the Home page, select the RECEIVER item from the required feed then click .

* In the Parameters window, select the Output tab.

* Select the SDI 1 tab. If the SDI tab is not present under the Output tab:

Click the  to bring up a prompt to add a new output

* Select SDI from the drop down menu

* Click the Add button to complete and add the SDI output tab

* Select the SDI port required from the drop down menu.

* Select any required video options as detailed in the
  SDI output parameters section

  SDI ports in use by other running services are listed in the drop-down menu, along with the associated
  service name. A service configured to use an **SDI port** that is already in use will be prevented
  from running.

If an SDI port appears to be missing or listed as 3G-capable instead of 12G-capable, this may be due
to the selected **ASI/SDI mode**. Refer to the **Configuring ASI/SDI mode** section to update the setting.
