The Outputs There are thirty-two general purpose outputs, located on the
three Tally connectors (25 way D-type) on the rear of the
switcher mainframe. Each output may be independently
programmed to “indicate” any one of a wide range of
occurrences or combinations of occurrences. These
occurrences fall into five groups (six if the Quad DSK option is
fitted) which are detailed below.
Video Tally Each output may be set to Tally any one of the video inputs.
Bus Tally The use of a particular bus may be tallied.
Trans Running The transitions, Fade to Black, Program / Preset, DSK or M/E
are tallied. If the Quad DSK option is fitted the four external
DSK transitions may be tallied.
T/L Running A particular timeline may be tallied, including those of an
external DSK, where fitted. Also a Tally may be generated if
any timeline is running.
T/L User Bits Six “flag” bits are available which can be linked to specific
keyframes on specific timelines. These bits may be used as
tallies.
Ext DSK Tally The background, key fill and key cut signals of the four
(option) external DSKs may be tallied.
Key Action Triggers fired from a Skateboard or via a Key Macro.
Note A complete list of all of the “occurrences” which may be tallied
on the General Purpose Outputs (GPO) is on page 27.
