Pin 5 +12 VDC Out
Capable of supplying 50 mA Max through a 100 mA fuse.
Pin 6 Warning Out
Tape transport malfunction. Driven Low when a malfunction occurs, oth5V.
Pulled up to +5V through a 4.7K
Ω
resistor.
Pin 7 Low Tape Out
When in RECORD mode and about 6% of the tape remains before the end of the video
tape, the output becomes active (0V) and can sink 10 mA of current. When inactive
(+5V), it is pulled to +5V through a 4.7K
Ω
resistor.
Pin 8 Rec Check In
Accepts a contact closure to Ground or TTL level signal. The closure or TTL LOW level
activates the REC CHECK mode provided the recorder is in the RECORD mode.
Pin 9 Timer Output
Output follows the levels defined in the Timer menu. See Timer Program Submenu on
page 31 for more information. When ON (0V), can sink 10mA of current. When OFF
(5V), is pulled to 5V through a 4.7K
Ω
resistor.
Figure A-2 Optional VCR Connection
Pin 10 Rec Start In
Accepts a +5V level input or a TTL level signal. The +5V input or TTL HIGH level
activates the RECORD mode. May be used in conjunction with another recorder with
this input connected to the Tape End output Pin 11 through a resistor voltage divider
(see
Figure A-2 ). When tape runs out on the first recorder, this function will put the
second recorder into RECORD mode.
