EDID M ANAGEMENT
Each DVI sink ( eg. monitors, projectors, plasma displays, switcher inputs) must
support the EDID data structure. Source BIOS and operating systems are likely to
query the sink using DDC2B protocol to determine what pixel formats and interface
is supported. DVI standard makes use of EDID data structure for the identification
of the monitor type and capabilities. Most DVI sources (VGA cards, set top boxes,
etc) will output DVI signal after accepting the connected sink’s EDID information. In
case of EDID readout failure or missing EDID the source will not output DVI video
signal.
MX4x4DVI and MX4x4DVI-DL provides an advanced EDID Management feature
with advanced functions that helps system integration. The built in EDID Router
stores and emulates 100 EDID data and all monitor's EDID's that are connected to
the output connectors. 50 EDID's are factory presets, while memories 50 to 99 are
user programmable.
On all inputs there can be emulated different or same EDID's, that are copied from
EDID router's memory, or the attached monitor. For example, the router can be set
up to emulate any device, that is connected to one of the inputs, and the EDID is
automatically changed, if the monitor is replaced with an other.
EDID Router can be controlled with included Matrix Control Software via RS232
port or Ethernet.
