The figure below illustrates a close-up of the M/E connectors on the VPx. Even though the
figure uses M/E 1’s board, all M/E connections are identical on the VPx.
Figure 2-6. M/E Connectors, VPx
On each M/E, one input connection is provided for layer A, one for layer B, and two “Link
connectors for inter-Processor communications.
Following are descriptions of each M/E connector on a VPx.
a) DVI Input A
One DVI-I connector is provided for both digital and analog inputs to the M/E’s
Layer A and background channel.
~Digital — connect a digital graphics source directly, or connect the
output of a digital graphics router.
~Analog — using the appropriate adapter cable, connect an analog VGA
source directly, or connect the output of a VGA router.
Refer to the “M/E Input Notes” section on page56 for important details on the u se
of this connector’s analog component. In Appendix A, refer to the “DVI-I
Connector Pinouts” section on page370 for pinout details.
Note The M/E connectors on a VPx are identical to those on a VP,
minus the analog and HD/SDI connectors.

Important In a widescreen configuration, a VPx cannot function in a
standalone manner, but must always work downstream of a
standard VP. Here, a VPx cannot be the first processor in an
Encore configuration.
In the special widescreen “preview” configuration, a VPx can
be used as a standalone destination that accepts DVI input
signals only — but no other input types are accepted, and no
genlock circuitry is provided.
