RECORD
ON COMMAND
HOW TO USE ROC
The Record On Command, (ROC), feature permits the user to
control when frames are recorded. The record command signal
from the user is input through the ROC IN connector on the rear
of the Processor. The signal supplied must be TTL compatible.
Don’t worry about the polarity of the signal as the Processor has
a means of changing the polarity if needed.
There are two ROC operating modes, ROC LEVEL and BURST
ROC. For ROC LEVEL operation the record command signal must
be “true” for the entire time you wish to record. For BURST ROC
operation the record command signal need only change state to
begin recording the number of frames specified with the keypad.
When the ROC feature is being used, ROC, for ROC LEVEL
operation, or BROC, for BURST ROC operation, appears on the
right side of the DATA-FRAME Border. When the Processor
senses a record command signal a solid white box appears to the
right of the ROC field in the DATA-FRAME Border. This white
box or ROC Indicator is driven by the user‘s command signal.
If the ROC indicator behaves just the opposite of what you
expected, the polarity of the command signal needs to be
changed. There is a switch labeled INVERT next to the ROC IN
connector. Change the position of this switch to change the
polarity of the record command signal. The ROC Indicator
should now behave and come on when you want it to.
