LTC 2600 Series Section 3 Operation
3.1Guide to Multiplexer Operation
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 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.
3.2 Live (Display)
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 , MULTI . All alarm, action,
and video loss warnings are displayed on this monitor.
Monitor B Under normal operating modes, Monitor B will display the selected camera in full screen or sequencing
only. 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.
For LTC 2672 and LTC 2682 series (System4 Duplex) Only: 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
callup will occur only when monitor B is in full screen mode.
