Operator`s manual

Every auto transition rate is constantly visible - including the main transition rates, the
dedicated keyer rates, and the fade to black rate. The last memory number recalled per
MLE is also displayed along with an associated eight-character memory name.
General Purpose Interface
The Synergy 4 MD-X is equipped with ten dedicated GPI inputs and ten dedicated GPI
outputs.
The GPI inputs allow the switcher to interface with peripheral equipment such as editors
and DVEs. Each GPI input can be used to perform simple editing and switcher functions
such as fade to black or an auto transition on one of the switcher’s MLEs. GPI inputs can
trigger Custom Control macros, making it possible to trigger complex timelines. For
industry standard serial editing capability, option S4MDX-900: Editor Interface is
available.
GPI inputs can be used by DVEs to indicate Aux Bus on air status to the switcher. For
more complex DVE integration, refer to option S4MDX-902: DVE Send and Remote
Control.
GPI outputs are used to trigger remote events like “Still Store Next Page” and are activated
through the switcher’s Custom Control macro system.
Emergency Bypass Tallies
The Synergy MD-X frame also includes 2 dedicated power-fail relays. These normally closed
relays open in the event of a power failure, or other system fault that prevents a reliable
program output (for example, removal of a Video Output card). These relays can be used
to control an external emergency routing system.
36 Tally Outputs
The standard system includes 36 tally relays located in the control panel conveniently close
to your monitors. Any tally can be assigned to any video input (or MLE program output)
making 36 enough for most systems. As each tally is assignable, more than one tally can
be assigned to the same source. This can simplify system cabling in situations such as
when camera tallies must be supplied to both the camera itself and the control room
monitor wall.
An optional 36 additional tallies can be ordered for red/green preview tally systems and
Aux Bus tally systems that require twice as many tallies or for cases where more than 36
inputs must be tallied. See option S4MDX-070: Extended Tallies.
System Manuals
The Synergy 4 MD-X comes with a complete set of system documentation that includes an
Operator’s Manual and an Engineering Manual.
10 Meter Control Cable
A single, standard 8-pin flat-shielded Telco cable that uses high speed RS-422
communication connects the Synergy 4 control panel and MD-X rack frame. The
maximum cable length between the control panel and its rack frame is 1,000 feet or 305
meters.
