VEXT Pulse Out
The Video External Pulse connection (VEXT) simplifies multiplexer operation by automatically synchronizing the multiplexer
and the DTL-960e. The DTL-960e 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 DTL-960e.
The VEXT connection is especially beneficial for units configured with dual record speeds (Normal and Alarm).
