0150-0255C 1-5 Kalatel VDR
Alarm Out
The Alarm output is activated while the Alarm Input is active.
The Alarm output is only active for the duration of the alarm
event. Output: Active Low
High: 12V
Low: Ground
Current Out: 50mA Max
Short Circuit Protected.
Low for duration of alarm.
Record Start In
Record Start In will place the unit in Record mode when
activated. Compatible with the Disk End Out signal from a
second unit. Input: Active Low TTL w/ pull-ups
or Normally Open Relay.
High: 5V (12V tolerant)
Low: Ground
Minimum Duration: 0.5 Seconds
Alarm Record Reset
This feature is for future development, and has not yet been implemented.
VEXT Pulse Out
Output: Active Low
High: 5V
Low: Ground (0.8V Max)
Current Out: 50mA Max
Short Circuit Protected. The Video External Pulse connection (VEXT) simplifies
multiplexer operation by automatically synchronizing the
Multiplexer and the VDR.
The VDR sends a VEXT pulse to the Multiplexer indicating that it
is ready to record the next image. The Multiplexer responds by
sending the next image to the Video Input on the VDR.
The VEXT connection is especially beneficial for units
configured with dual record speeds (Normal and Alarm).
Use of the VEXT connection is Highly Recommended when
connecting the unit to a multiplexer.
Error Out
The Error Out signal is activated when the unit experiences any
operational or internal error. Output: Open Collector
High: Transistor Off
Low: Transistor On
Active When On.
Current Out: 10mA Max
Minimum Duration: 0.5 Seconds
Videoloss Out
The Videoloss Out signal is activated when the unit experiences
videoloss on the video input (Composite).
In the event of videoloss, VIDEOLOSS will be indicated near the
upper left hand corner of the primary monitor.
Output: Open Collector
High: Transistor Off
Low: Transistor On
Active When On.
Current Out: 10mA Max
Minimum Duration: 0.5 Seconds
