Set up the SDI/ASI card for HD, UHD or ASI operation

In the current version of CE1, the card variant for HD, UHD or ASI operation is not set via the UI so you need to manually set the SDI card variant before configuring it for the required use case.

• Variant 1:

  • Quad SDI input (each input is up to 3G-SDI)
  • ASI output
  • 4 Independent SDI inputs (each input us up to 3G-SDI)

• Variant 2 for either:

  • 1 UHD channel over 12G-SDI on port 1
  • 1 UHD channel over 4x3G-SDI on ports 1,2,3 and 4
  • 1 HD channel over HD-SDI / 3G-SDI on port 1
  • No ASI

1. Connect to the unit using SSH.

2. If you have only one card, follow these steps to set the card variant:

   1. Edit the file (using vi) or set the value in it using cat:

      sudo chmod +777 /var/opt/mediakind/platform/dta_2174b_variant_force
      echo 2 > /var/opt/mediakind/platform/dta_2174b_variant_force

      The file contains 1 or 2 which is the variant number.

   2. Check the value is correct:

      cat /var/opt/mediakind/platform/dta_2174b_variant_force

3. If you have two cards, follow these steps to configure the card variant independently:
   The first card is set to 1 for ASI operation, the second card is set to 3 for UHD operation.

   1. Edit the file (using vi) or set the value in it using cat:

      echo 1 > /var/opt/mediakind/platform/dta_2174b_variant_force/1
      echo 3 > /var/opt/mediakind/platform/dta_2174b_variant_force/2                            

      The two files 1 and 2 under the folder now contain the values 1 and 3 respectively.

   2. To set the second card back to HD operation, enter:

      echo 1 > /var/opt/mediakind/platform/dta_2174b_variant_force/2

   3. Check the value is correct:

      cat /var/opt/mediakind/platform/dta_2174b_variant_force

4. Reboot the unit:

   sudo reboot

   The 12G-SDI or 4x3G Quadrant is automatically detected.
