This module can be mounted in a GeckoFlex
frame when ordered with the 8900V-R GeckoFlex
Video rear.
8950DAC
Component video D-to-A converter
Use the 8950DAC to display a serial
component digital signal on an analog RGB
monitor, to record a digital video signal to an
analog component VTR, or to send digital video
to a component analog switcher. The 8950DAC
is compact and fits in the 8900-V frame.
