This field is used in cascading configurations only and contains the

current video input device. For more details, please refer to the
CASCADING section of the Commissioning Manual.
For VideoBlox subrack, the Bypass subrack ID value should be 1-16,

inputs, the bypass ID is 1, and for the next 1-255 inputs, the bypass ID
is 2, and so on.
This field may be used in both cascading and combining
configurations. In a cascading configuration consisting of three
subracks, the COMBINER SUBRACK ID contains the address of the
second subrack that is to be bypassed when selecting the current
video input device. For more details, please refer to the CASCADING
section of the Commissioning Manual. The following figure shows
typical entries for a cascaded system:
In combining configurations, this field contains the address of the
combiner subrack. For more details, please refer to the COMBINING
section of the Commissioning Manual.
The valid address values are 0 (signifying no cascading or combining
are used) through to 99.
This field defines the combiner inputs to which the preselector subrack
for the current video input is connected. Up to 32 preselector subracks
may be configured. The combiner inputs for these are labeled A – Z
and AA – AF. For more details please refer to the COMBINING section
of the Commissioning Manual.
