Unit type

You can operate the ZS-SX in multiplexer or multi­viewer mode. In multiplexer mode, the ZS-SX supplies
the images of selected cameras to one or more inter­faced video recorders. In multiviewer mode, the ZS-SX
functions as a comfortable image splitter. During
playback and in multiviewer mode the ZS-SX offers
various digital video functions such as zoom, freeze
frame or pan.

Digital video functions

Several different monitor display modes are available,
including the following:

❚ Frame-by-frame display of individual camera

images

❚ Simultaneous display of 4, 9, 10 or

16 camera images on a single screen

❚ In multiviewer mode additional 10-segment split-

screen including 2 larger segments

❚ Electronically-operated 2X zoom in conjunction

with electronic pan-and-tilt function

❚ Freeze-frame

Summary of functions

Digital ZS-SX series multiplexers are available in two
different configurations:

❚ ZS-SX116P, for use with up to 16 color cameras

❚ ZS-SX109P, for use with up to 9 color cameras

Programming

Menu-based programming of the multiplexer is carried
out using the on-screen display. The most important
settings can be programmed in just a few minutes,
using the Quick-Setup menu.

Two serial port interfaces are provided to allow PC­based remote control of the multiplexer and the con­nection of a remote control panel.

Alarm functions

An additional external alarm sensor can be assigned
to each camera input connection. Each sensor alarm
activates an acoustic and an optical signal, along with
further functions if required.

The monitor normally displays the images from each
camera in a pre-programmed sequence or as individ­ual full screen pictures. The system can be pro­grammed to display – in case of an alarm – only the
images from the camera involved in the alarm activa­tion.

Any loss of video signal caused by a malfunctioning
camera likewise activates an alarm.

information is normally displayed on-screen. This infor­mation provides details of the camera involved. The
texts that can appear superimposed are as follows:

ALARM Alarm proceeding from external source

AL Alarm proceeding from external source

VL Alarm due to camera failure

16 ZS-SX Series

(06/2000)

Acknowledging an alarm

Alarms are automatically reset after a maximum of five
minutes, or have to be reset manually. The details
depend on how the system has been programmed.

The alarm function of the multiplexer can be pro­grammed so that an alarm message remains active
(even if it has been acknowledged) as long as the
cause of the alarm – such as an open door – has not
been rectified. In this case, the alarm cannot be reset
unless appropriate steps are taken (e.g. by shutting
the door) to remove the original cause. Once the
cause of the alarm has been dealt with, the alarm
button will stop flashing and light up continuously.

• Press the ALARM RESET button to acknowledge
the alarm. The red alarm button will stop flashing.

• If the alarm is still active, wait for the button to light
up continuously. Then press the ALARM RESET
button to acknowledge the alarm. The red light on
the alarm button will go out.
