1.2.1 Operating modes
The LongView 5000 extender system maximize the data that is transferred between them. The achievable throughput
depends upon the length and quality of the cable links that join the units.
Video signals are most sensitive to link quality and for this reason the extenders have two modes of operation: low rate mode
and high rate mode. The extenders periodically check the link quality and determine which video transfer mode can be
successfully used. The difference between the two modes is considerable as high rate mode can deliver over twice the video
bandwidth. You can also choose which mode to use by using the Hotkey functions. For more information, see
When the link mode changes, on-screen icons are displayed, while the indicators on the front panels of both units show which
mode is currently being used. If a rate change occurs, the entire data link is reset causing a momentary loss of the video, audio
and USB services.
