LTC 2600 Series Section 6 Operation
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.

Press the MULTI key repeatedly to toggle through the different multiscreen display options.
Cameo Mode : When in MULTI or QUAD modes, the screen area where a camera is displayed is called a
CAMEO. Note that the numbered front panel keys can refer to either cameras or cameos. Press the
CAMEO
key to enable the operation of these keys in the cameo function. (The CAMEO LED is illuminated
when the multiplexer is in the CAMEO mode.) Press the CAMEO key again to revert to the camera function.
Cameras can be assigned to any selected cameo and can be changed as often as required. This can be done by one
of the following:
• Assigning all cameras : Press the ALT key.The ALT LED will illuminate, then press the SELECT key. The
first cameo will be selected and show a flashing camera title. By pressing the desired camera key, that camera
will be assigned to the cameo, and the next cameo is automatically selected (shown by the flashing camera
titles). Again press the selected camera key; this is assigned and the process repeated until all cameos have
been assigned a camera. Press the ALT
key to exit.
• Individual assignments : In the MULTI or QUAD mode, the Camera keys are assigned as Cameo keys
automatically. Select relevant cameo key, 1 to 16. The relevant cameo is selected. Press the CAMEO key.
The cameo keys revert back to selecting cameras. Press camera key to assign the selected camera to cameo.
Press CAMEO
to exit.
Zoom : Enables the active camera display (a cameo in multi or quad display) to be digitally enlarged by a factor of
4:1. “Zoom” will be displayed on the monitor screen. Selecting any other camera (using the camera keys) will
display that camera image in full screen enlarged mode. The arrow keys allow closer inspection of any part of the
selected image.
