Pelco Manual C1515M-A (11/01) 83
RS-485 This is an Electronics Industry Association (EIA) interface
standard used for communication between multiple
transmitters and receivers; the maximum recommended
distance is 4,000 feet (1,219 m). The four-wire connection
provides two wires for transmit and two wires for receive.
NOTE:
The electrical communication scheme used by
Pelco is a direct-coupled method, not an AC-coupled
method. Therefore, if the ground potential of the wire at its
two end points is different (other than zero volts), an
additional wire is required as a ground.
Scratchpad sequence A scratchpad sequence can be run on an individual
system monitor, without entering the password-protected
CM6800 Matrix Switcher on-screen programming menus.
You can program scratchpad sequences from the
CM6800 Matrix Switcher on-screen programming menus
only, not from the CM6800-MGR software.
Sequence Allows an operator to see a routine of 72 camera views on
any system monitor, over and over again. The sequence
can be operated automatically or manually. The order in
which the camera views appear and the time each view
remains can be programmed.
Standard Coaxitron This is Pelco’s Coaxitron control technology that uses 15
bits to send a command.
Star configuration This is a way of providing multiple direct connections from
one source. A star configuration uses a separate cable for
each direct connection, with all of the cables connected to
a central device. When connecting PTZ cameras to a
matrix switcher, for example, the central device can be a
code distribution unit, such as the CM9760-CDU-T. Each
camera has a direct connection to the CM9760-CDU-T,
which is the central device.
Synchronize Since the CM6800 Matrix Switcher can be programmed
from either the CM6800-MGR software or the CM6800
Matrix Switcher on-screen programming menus, you could
potentially have different settings in the two programming
sources. Pelco recommends transmitting any
programming changes from the updated programming
source so that the next time you make changes from
either programming source, you will be modifying the
current system settings. Refer to Transmitting
Programming Settings.
System keyboard This is a keyboard compatible with and connected to the
matrix switcher, allowing a system operator manual
control over the system.
System reset This restores the system to the default settings, as
shipped from the factory.
Vertical drive/synchronization This option sends a timing pulse from the matrix switcher
to a compatible camera. The camera aligns the vertical
synchronization with the timing pulse.
Zone A zone is a user-defined, physical location to which (1) a
label is attached and (2) a camera is associated. When
the associated camera is panned through or remains
within this defined zone, the zone label appears on the
monitor. With some camera systems, a zone can be
blanked to prevent viewing while the camera is positioned
in the zone.
