 A slightly quicker way to edit this file is to use the following command:
     echo 2 > /var/opt/mediakind/platform/dta_2174b_variant_force
+After 'echo' type a 1 or 2 depending on whether you want HD (1) or UHD (2) then reboot.

+==== Multiple SDI Cards ====
+If you have multiple SDI cards (say in EL G9 where you could have 3 cards) you can use the following:
 \\
-After 'echo' type a 1 or 2 depending on whether you want HD (1) or UHD (2) then reboot.
 \\
+Navigate to the following directory:
 \\
+  /var/opt/mediakind/platform
+\\
+There should be a file here called:
+  dta_217x_platform
+\\
+rename this file or you won't be able to create the relevant directory:
+\\
+  mv dta_217x_platform dta_217x_platform.org
+\\
+Now you can create the following directory (ensure you are in /var/opt/mediakind/platform)
+\\
+  mkdir dta_217x_variant
+\\
+Navigate to /var/opt/mediakind/platform/dta_217x_variant
+\\
+  cd /var/opt/mediakind/platform/dta_217x_variant
+\\
+To set the card variant type we need to assign a number for that card mode, lets assume we want card 1 in HD mode (variant 1) and card 2 in UHD mode (variant 2):
+\\
+  echo 1 > /var/opt/mediakind/platform/dta_217x_variant/1
+  echo 2 > /var/opt/mediakind/platform/dta_217x_variant/2
+\\
+This file is read at boot, so for the configuration to apply you need to reboot the unit.

+==== Variant Modes ====
