About the DX-700
dêçìéáåÖ=lìíéìíë
Within a single bank of a DX-700, you can group up to six physical outputs in a bank to
form a larger logical output display. This grouping enables you to control an LED display
that is larger than can be controlled with a single output.
The Display Layout Menu within the Setup Wizard is used to implement grouping, after
you have set up two or more outputs in a single bank. In Chapter 4, refer to the “Using the
Setup Wizard” section on page80 for more information ab out grouping outputs.

Stacking is the practice of increasing the canvas size in order to display video output across
a larger area, either horizontally or vertically. The DX-700 provides two types of stacking:
•“External” stacking occurs across DX-700 machines. In this configuration, you
create physical connections across two or more DX-700s. Each machine’s inputs
are made available to the next DX-700(s). A "lock" signal must also be sent from
the "master" frame to all "slave" frames in the stack.
•“Cross-bank” stacking occurs across banks in a single DX-700 unit. In this
type of stacking, one bank’s input connectors are linked to the corresponding input
connectors of another bank. This function allows a single input source to be
visible on the canvas of both banks.
The following topics are discussed in this section:
•External Stacking
•Cross-bank Stacking
•Stacking and Video Delay
•Expansion Links

The external stacking function enables multiple DX-700 units to be joined together in order
to increase the overall canvas size — either horizontally or vertically. When working in this
mode, all DX-700 units must have the same configuration, as follows:
•Video sources are all connected to input modules of the “master” DX-700.
•On each of the master’s input modules, the Expansion Out DVI port is connected
to the DVI Input port on the first slave unit’s input modules. Similarly, the first
slave connects to the second, etc.
•A Sync output on the master unit’s System module allows slave units to genlock.
This signal can also be daisy-chained to several DX-700=units.

The expansion links on a DX-700 input module can be used to connect multiple banks
together within a single DX-700 chassis — a feature called cross-bank stacking. The
advantage is that a single input can be displayed across multiple banks.
For cross-bank stacking, the linked banks must all have the same configuration, as follows:
•Video sources are all connected to the first bank’s input modules.
Note Use Director Toolset to set up external stacking.
