Figure 4. Duplex Multiplexer with CM6700 Matrix Switcher
The MX4000 Genex Series lets you configure your system in various ways.
The simplest system is a stand-alone multiplexer (Figure 1). Just connect cameras,
monitors, a VCR, and alarm inputs. Front panel push buttons control the multiplexer.
By adding a KBD4000/KBD4002 keyboard to the multiplexer (Figure 2), you can control
1-16 multiplexers from up to 25 feet (7.6 m) away with the cable supplied with the key-
board. You can obtain greater distances between the multiplexer and the keyboard by
providing a Pelco KBDKIT(-X) and your own cable.
A keyboard also lets you control moveable cameras. Control systems for moveable
cameras must be Coaxitron
®
compatible. In Figure 1 cameras are fixed.
The systems shown in Figures 1 and 2 are for a single operator only. To permit up to four
operators to use the system, add an MX4000SVR Multiplexer Server, as shown in Figure 3.
Main and spot monitor outputs from each multiplexer are connected to the server, providing two
video channels. The design is not a true matrix, however, because only two operators (instead
of all operators in a true matrix ) can select cameras from the same multiplexer at the same
time, one operator using the main monitor and the other operator using the spot monitor.
Duplex Multiplexer Only–If a true matrix configuration is necessary in which all operators
can access a multiplexer, a matrix switcher (such as Pelco’s CM6700) can be used. Refer
to Figure 4. However, only one multiplexer can be used. In this example, looped video is
from individual cameras; video from the main monitor can be either from individual cameras
or from multiplexed cameras.
NOTE: The KBD4000 and
KBD4002 keyboards in
combination with a multi-
plexer provide Coaxitron
control of pan, tilt, and lens
functions.
When used with 32-bit ex-
tended Coaxitron receivers,
such as Intercept
®
, Spectra
®
,
IRD/ERD2000 Series, and
LRD41C21/LRD41C22
Series, the KBD4000/
KBD4002 keyboard in
conjunction with a multi-
plexer will support all pan,
tilt, and lens functions; auxil-
iary on/off; and the setting
and calling of presets and
patterns. It will not support
programming of labels for
presets or patterns. If
labels for presets or patterns
are required, program them
with a different control, such
as the MPT9500.
