Analog Input Processing
TRX-VI-33100 Module
The TRX-VI-33100 video input module consists of a 16-input “uni-
versal” base board (VI-33100) and a 16-input digital-only mezzanine
board (HI-33201).
The VI-33100 universal base board auto-senses and accepts 16 com-
posite analog SD, digital SD, or digital HD signals in any combination
and passes them in digital SD or digital HD form (as appropriate) to the
Trinix matrix board. When analog signals are received, an extensive set
of gain, phase, filtering, and other adjustments are available for each
signal. These adjustments are summarized below.
