Introduction, cont'd
The 2U frame has four single board slots, the 3U frame has six single board slots,
the 4U frame has eight slots, and the 5U has ten slots. Each slot supports power
and control connections to the I/O boards. When a board is installed into a slot it
may use more than one slot. For example the SMX 1616 VGA board uses four slots.
The slots a board covers are not available for other I/O board installation until that
(multi-slot) board has been removed. See

(also called configuration 0).
Up to 32 global memory presets can be stored. Preset locations are assigned
to the input buttons and output buttons and can be selected from the front
panel, by serial port, or Ethernet control, for either saving or retrieving.
When a preset is recalled from memory, it becomes the current configuration.
plane presets per switching plane can be saved and recalled without affecting
the other I/O plane connections. A plane is all the inputs and outputs of one
signal type.

was developed by DDWG (Digital Display Work Group). This connection
standard offers two different connectors: one with 24 pins that handles digital
video signals only, and one with 29 pins that handles both digital and analog
video. This standard uses TDMS (Transition Minimized Differential Signal)
from Silicon Image and DDC (Display Data Channel) from VESA (Video
Electronics Standards Association). DVI-D supports digital signal transfer
only, and DVI-I supports both digital and analog signal transfer.
the HDMI Working Group that combines video, multi-channel audio, and
control signals into a single digital interface for use with DVD players, digital
television, and other audiovisual devices.
This is a 10-bit, scrambled, polarity independent interface with common
scrambling for both component ITU-R 601 and composite digital video and
four channels of (embedded) digital audio.
standard transmits audio and video over a single coaxial cable with a data
rate of 1.485 Gbit/second.
