NTI VEEMUX VIDEO MATRIX SWITCH

DDC SUPPORT
(Optional)
DDC information allows the CPU to automatically select the optimal resolution for the monitor by receiving, at power up,
information from the monitor concerning its resolution specifications.
When DDC Support is installed, the DDC information is acquired from the monitor by the VEEMUX-A switch when the VEEMUX-A
is powered-up. A monitor with DDC support must be connected to MONITOR 1 for this to occur. The DDC information will
be made available at every CPU port.
The DDC information can also be acquired by pressing the DDC button located on the front of the switch. This button allows the
monitor configuration to be changed without powering down the switch.
Notes:
1. All monitors connected to the VEEMUX-A switch with DDC support must be able to support at least the maximum
resolution of the DDC monitor connected to '"MONITOR 1".
2. In order for the CPU to correctly receive the DDC information from the switch at boot-up, the switch must be
powered up before all attached CPUs.
