Display speed acceleration
6.7.1
M7xx range sets
Display speed acceleration is supported by sets in the M7xx range.
Three conditions are required to implement it:
•
sets in the M7xx range,
•
a system running at least release R1.3,
•
a cabinet equipped with cards that are adapted for display speed acceleration.
Refer to the product catalogue to identify the display speed acceleration variants for the cards in
question.
6.7.2
i7xx range sets
Display speed acceleration is a basic function on the i7xx range sets.
