Split Board Configuration (Limited Quantity of Any Input
Type)
AKA: 8 Video, Up to 8 S-Video/Video, and Up to 8 Component/S-Video/Video
Sources
NOTE: Dealing with a system that contains more than 16 sources? This
configuration may be preferred as long as the system does not contain more than
eight component video sources.
This configuration somewhat mimics the out-of-the-box configuration, but there are
differences. The first difference is that jumpers need to be removed and the cable
assembly must be attached. Refer to "Cabling and Jumpers" on page 12 for details.
Secondly, even though the total number of mixed sources allowed in this
configuration is greater, it does not permit more than eight component sources at any
time.
The following figure illustrates the effect of connecting the cable between the level 1
and level 3 boards and removing the jumpers from the level 3 board. Eight level 3
inputs become an extension of the level 1 board, resulting in a logical 24X8 switcher
on level 1, a 16X8 switcher on level 2; and an 8X8 switcher on level 3.
