VPx Hardware

smñ=jLb=`çååÉÅíçêë

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.

Note

The M/E connectors on a VPx are identical to those on a VP, minus the analog and HD/SDI connectors.

b)Source Link Out

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 source directly.

Refer to the “M/E Input Notes” section on page 14 for important details on the use of this connector’s analog component.

b)Source Link Out

One DVI connector is provided for the M/E’s Source Link Output. For wide screen and multi-screen applications, this connector loops your inputs to the next VP or VPx in the chain. Because all analog and digital inputs reside in the digital domain, each “link” output loops those inputs to the next Processor’s scalers.

An M/E’s Source Link Output must always be connected to its associated M/E Source Link Input on the next chassis, and never cross-routed.

Please note:

In a multi-chassis configuration, the link can extend to all chassis. In all cases, the looped inputs are “pre-scaler.”

c)Source Link In

One DVI connector is provided for the M/E’s Source Link Input. For wide screen and multi-screen applications, this connector accepts the looped outputs from the
