OVERVIEW
This manual describes the installation and operation of the following DVS Series Des top
Video Switchers:
The products in the DVS Series have a number of common features:
 Easy setup using on-screen menus.
 Simple controls and indicators.
 Manual selection of cameras.
 Automatic camera sequencing feature, with dwell time control for each camera.
 User-definable camera titles.
Aside from these common features, DVS Series switchers fall into two groupsthose with
alarm functionality, and those without.
DVS14 and DVS18
The DVS14 can be connected to four camera inputs whilst the DVS18 can be connected to
eight. Both products are used to switch the images from these inputs onto one output
monitor. Neither the DVS14 nor the DVS18 has alarm functionality.

OVERVIEW
DVS24A and DVS28A
The DVS24A can be connected to four camera inputs whilst the DVS28A can be connected
to eight. They can also be connected to a second monitor. Li e the main monitor, the
second monitor can be used to show images from each of the camera inputs, and can be
set to run automatic camera sequences. In a sequence on the second monitor, a global
dwell time applies to all cameras and this can be adjusted if required. Sequences can also
be run simultaneously on both monitors.
Both the DVS24A and DVS28A units have alarm functionality. The alarm inputs are designed
so that when an alarm is triggered, the main monitor displays the image from the
corresponding camera input, while the second monitor will continue as before, displaying
images from an automatic sequence or from a manually selected camera. In this way, the
operator can retain control over all camera inputs while the images from the camera input
under alarm are examined.

CO ECTI G THE SWITCHER
To connect a DVS Series Des top Video Switcher, follow the instructions below, using the
figures on page 7 as a guide:
1. Ensure that all the video connections from the cameras and monitors are made using
coaxial cable terminated by a 75W BNC connector.
Note: The switcher is not intended for loop through. Video inputs requiring loop through
should be unterminated at the peripheral device, as 75ohm termination is provided by
the switcher.
2. Connect a cable from the main monitor to the BNC soc et mar ed MAIN. If the switcher
is a DVS24A or DVS28A and a second monitor is being used, connect this monitor to
the lower BNC soc et, which is mar ed SPOT.
3. Connect cables from the cameras to the video input BNC soc ets. The BNC soc ets
are numbered:
 1-4 on the DVS14 and DVS24A.
 1-8 on the DVS18 and DVS28A.
4. If you are using a switcher with alarm inputs (DVS24A or DVS28A) connect the Alarms
I/O Connector.
5. Connect the jac -plug from the 12V DC power supply into the jac -soc et mar ed 12V
DC. Use the power supply cable strain relief point to prevent the power cable from
being accidentally pulled out.
Figure 4 - Power supply cable strain relief point
6. Plug the 12V DC power supply into a nearby mains power outlet. This outlet should be
easily accessible so that the switcher can be unplugged if necessary.
7. Switch on the cameras, monitors and the DVS Series Des top Video Switcher at the
mains power outlet.
When the power is switched on, the switcher will display the images from a single
camera or it may begin to switch cameras sequentially, depending on the operation
selected when it was last switched off. If the switcher cannot find any camera inputs, it
will scan through the camera selection LEDs, displaying a NO VIDEO message on the
monitor.
Note: Whenever the power is lost from a switcher, it stores the last nown operation.
When it is restarted, the switcher will resume this last nown operation (e.g., video from the
last selected camera or a sequence).

Installation and Operating Manual DVS Series
ALARM I/O CO ECTOR
The Alarm I/O Connector is a 15 way D-type connector located on the rear panel of the
DVS24A and DVS28A. It allows the connection of both alarm inputs and alarm outputs to
the switcher.
Alarm Inputs
Each alarm input can be connected to the normally-open contact of devices such as pressure
pads, passive infrared detectors, or smo e detectors etc. The alarm will be triggered when
the external contact closes. Wire the devices to the Alarms I/O Connector accordingly.

Figure 5 - Alarm Input Connections
Alarm Outputs
An internal relay is provided so that the DVS can be connected to other equipment.
The behaviour of this relay can be programmed using the menu system, in order to suit the
alarm output connected. It can be configured so that when an alarm input is triggered, the
relay (and hence the alarm output) operates continuously or operates for one second from
the time the alarm is triggered. For more details on this configuration, see page 17.
The alarm relay operates in a fail-safe mode. When power is removed from the unit, the
relay reverts to its alarm condition.

Using these buttons, the units can be operated in one of two modesManual or Auto.
Manual Mode
To operate the unit in Manual mode, press the numbered buttons to view the corresponding
camera on the monitor. The LEDs above the buttons indicate which camera is currently
selected.
Pressing the button for a video source that doesnt have a camera connected to it will
display a NO VIDEO message until another camera is selected.
Auto Mode
To operate the unit in Auto mode, press the Auto button. The monitor will begin to show
images from each active camera in sequence. Any input that had no video signal present
when the unit was powered up will be omitted from the sequence. To add an input to the
sequence, connect it to a video signal and then manually select that input using the relevant
numbered button. When the sequence is restarted, the new input will be included.
When operating in Auto mode, the unit displays each camera input for a specific period of
time before displaying the image from the next camera and so on. This period of time is
nown as the dwell time and it can be adjusted for each camera individually using the on-
screen menu system (see page 16).
To exit Auto mode, press any of the numbered input selection buttons.
