SECTION 6: OPERATING THE LTC 2600 SERIES
VIDEO MULTIPLEXER
Operating the LTC 2600 Series Video Multiplexer requires a general knowledge of basic and combined operating
modes as described in this section.
Basic operating modes
are LIVE (Display), RECORD, and PLAYBACK.
Duplex multiplexer models
provide
combinations
of the basic modes (e.g. simultaneous recording plus
playback when two VCRs are used). When operating access is a concern, the multiplexer’s security lockout feature
can be enabled. Three levels of access are provided as described at the end of this section.
6.1 Live Display Mode
Live camera pictures can be displayed on monitors A and B.
•
Monitor A
is the main functional monitor and can be displayed in FULL, QUAD, or MULTI. Alarm, action, and
video loss warnings are displayed on this monitor.
•
Monitor B
will display the selected camera in full screen or sequencing under normal operating (recording)
modes. When an alarm or action input is detected, the corresponding camera picture with the flashing
Alarm/Action indicator will be displayed on Monitor B for the programmed dwell time. When multiple alarms
or actions occur, camera pictures will be sequenced on Monitor B at the two-second dwell time.
•
Multiscreen display modes
can be displayed on both Monitors (A and B). All alarm action and video loss
warnings are displayed on both monitors.The alarm/action call-up will occur only when Monitor B is in full
screen mode. Multiscreen will not be available on Monitor B during recording operations.
