through the disable/enable/cycle test modes, the UP/DOWN arrow keys to change between advance (-) and
delay (+), and the numeric keypad to change the number of frames of advance/delay. Use ENTER to record
each change, HOME to cancel. GPOs fire (drive low) for 1 video frame starting relative to the edit IN time. A
delay of +000 fires at the edit IN point, -001 fires 1 frame before the IN point, and is normally used for auto
transition purposes. Each GPO is set independently, and a timing of up to 999 frames before (-) or after (+) the
IN point is possible. The cycle test mode issues 1 frame GPO signals at a rate equal to the advance/delay
setting and is intended to test the device being GPI controlled. Zero will never issue test GPOs, 1 keeps the
GPO active (low) continuously, 2 produces a 2 frame square wave. The cycle test mode operates only when no
other timeline event (edit, preview, etc.) is in process. GPO settings are stored in Personality Registers.
See GENERAL PURPOSE OUTPUTS (GPO) for more information about GPOs, including manual triggering.
NOTE: Because all VTRs must achieve synch before the first GPO fires, the preroll time must be set to at least
2 frames longer than the earliest GPO’s advance time, or edits will not work.

Many aspects of the way the VTC-4000 works are adjustable by the user. Almost all of these settings are
stored in registers called Personality Registers. Ten personality registers are provided, allowing different users
to store their favorite configurations. A user may wish to use two or more registers to recall different modes of
operation depending on the task currently being undertaken. Registers may be named with alphanumeric
names up to sixteen characters long. Items stored in the personality registers include: Record modes for all
VTRs including channel enables and animation CELL DURATION, timecode type (LTC, VITC, Tape Timer),
preroll, Jog and Variable Play (slo-mo) adjustments, various key function options, and record end protect
values.
