    Cards with many heat-producing components should be arranged to avoid areas of excess heat build-up, particularly in frames using only convection cooling. The 9083 has a moderate power dissipation (15 W max.). As such, avoiding placing the card adjacent to other cards with similar dissipation values if possible.

    The input/output complement listed above represents the maximum capability of the 9083. The practical input/output complement is determined by the par- ticular Rear I/O Module used with the 9083. Refer to 9083 Rear I/O Modules (p. 1-21) for more information.

    A Reset Framesync function resets the frame sync following any horizontal or vertical offset changes, clearing any buffered audio and video and re-establishing the frame sync. The 9083 re-establishes video/audio sync following framesync changes by applying an offset in small, progressive amounts to provide a seamless, glitch-free retiming.
