APPLICATIONS
The MX4004 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/KBD4000V 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 keyboard. 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.
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,
KBD4002, and KBD4000V
keyboards in combination
with a multiplexer 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 Se-
ries, the KBD4000/KBD4002/
KBD4000V keyboard in con-
junction with a multiplexer will
support all the functions of a
15-bit standard Coaxitron
receiver, including 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.
