INSTALLATION & SETUP
Image Shift Synchronization Inputs & Outputs
The ISM'S multi-display synchronization feature is provided for multi-display
applications such as a stacked video display wall. This feature allows you to synchronize
image shifting amongst multiple ISMS. When used, all display images move both
horizontally and vertically at the exact same rate and in the same direction. Each ISM in
the system is ''chained'' to the next by a standard 3-conductor
phono cable. Te first ISM in
the chain is the ''master'' and all others are ''slaves''. A cable is connected between the
MULTI OUT jack of the first ISM to the MULTI IN jack of the next ISM in the chain.
This continues to the last ISM in the chain. The ''slave'' units are those in the chain that
have a cable connected to MULTI IN. The unit with only MULTI OUT connected is the
''master''. See Figure 2-27 below.
Note: It is recommended that a rough setup be performed on each ISM before linking
them together. When linked, the FAST/SLOW switch on each ''slave'' unit is not
functional. During setup, set the FAST/SLOW switch on each ''slave'' unit to SLOW (this
reduces picture noise that may be apparent if set to FAST).
The 3 conductor cable required to link ISMs is readily available from electronic supply
stores and is also available from Accurate Imaging. Alternatively, it is quite easy to make
up your own cable(s). For each cable, all that is required is two standard 3.5mm phono
plugs and a length of three conductor phono cable. Refer to Appendix D,
Communication
Cables for wiring details. It is recommended that the cable be a maximum of 15 feet in
length.
