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 Vista Solo.
The Vista Solo 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
Vista Solo.
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.

The Error Out signal is activated when the unit experiences any
operational or internal error. Output: Open Collector

Low: Transistor On
Active When On.
