INFORMATION
INDEX
In operation, many AdderLink XD522 installations generally require no intervention once
congured. The transmitter and receiver units take care of all connection control behind
the scenes so that you can continue to work unhindered.
FRONT PANEL INDICATORS
The six front panel indicators on each unit provide a useful guide to operation:
OPERATING MODES
AdderLink XD522 units try at all times to maximize the data that can be transferred
between them. The achievable throughput depends upon the length and quality of the
cable links that join the units. Please see Tips for achieving good quality links.
Video signals are most sensitive to link quality and for this reason the AdderLink XD522
units have two modes of operation: Low Rate and High Rate. The units 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. Please see Video support for details.
You can also choose which link rate mode you would prefer to use (subject to link cable
suitability) by using the Hotkey functions - please see next page for details.
On-screen icons are displayed on the video display whenever the link mode changes,
while the HR indicators on the front panels of both units continually show which mode
is currently being used. If a rate change does occur, the entire data link will be reset. This
will cause a momentary loss of the video, audio and USB services.
