INSTALLATION
This installation should be made by qualified service personnel
and should conform to all local codes. Safeguards must be
taken to avoid unintentional operation by employees and
personnel working about the premises, by falling objects, by
customers, by building vibration, and by similar causes.
Power Sources
The AD1996R CPU is configured for use with a 120 VAC, 60
Hz primary power source. The ADS1996RX is configured for
a 230 VAC, 50/60 Hz power source. The 120 VAC units are
supplied with a pendant 3-wire cord and plug for mating to the
primary source outlet. The 230 VAC units are supplied with a
Euro style IEC 320 type inlet. A suitable detachable cord
should be connected between the IEC 320 inlet and the power
source. The cord should conform to all national and local use
code requirements.
DO NOT PHYSICALLY CONNECT EQUIPMENT TO
THE POWER SOURCE UNTIL 'POWER UP'
PROCEDURES HAVE BEEN COMPLETED (page 1-5).
NOTE: THE SOCKET OUTLET SHALL BE LOCATED
NEAR THE EQUIPMENT AND SHALL BE READILY
ACCESSIBLE.
Mounting
The 1996R CPU is designed for installation into a standard 19-
inch EIA rack. The 1996R unit has a height of one rack unit
(1-3/4 inches, see Figure 1-1). 1996R units must be installed
with a minimum of one rack unit clearance between each unit
(1-3/4 inch). It is the responsibility of the installer to insure
proper airflow around the units to provide adequate ventilation.
1985A Standby Switch
Two 1996R CPU’s can be used with a Model 1985A Standby
Switch, where one 1996R is the primary controlling CPU and
the other is the backup CPU, operating in standby. All
keyboard and control interfaces are connected through the
1985A unit. Refer to the 1985A Installation Manual for
installation instructions. A typical connection of two 1996R
CPU’s with a 1985A is illustrated in the Appendix.
Note: An external computer (PC) can be connected to the
1996R CPU to up/download setup data. If a 1985A is used,
during up/download operations the PC must be connected
separately to each 1996R CPU, by-passing the 1985A.
External Control Interfaces
Ten RS-232 control ports are provided on the 1996R CPU (see
Connections, page 1-3). Each port can be configured for
control inputs from keyboards, external computers, or alarm
interface units, or for uploading or downloading data from an
external PC, or for printing alarm events. Several American
Dynamics keyboards are available for connection to the 1996R
CPU control ports. Executive model keyboards without
pan/tilt and lens controls are also available.
• 2078 - A full-function system operation and programming
keyboard with pushbutton lens control and vector solving
joystick for pan/tilt movement. It is available as a desktop or
rack mount unit.
• 1678CM - A full-function system operation and
programming keyboard with pushbutton lens control and
vector solving joystick for pan/tilt movement. It is available
as a desktop or rack mount unit.
• 1677 - An operator desktop or rack mounted model with
pushbutton lens and pan/tilt control.
• 1676B - An operator 5-monitor keyboard (desktop only)
with pushbutton lens control and joystick for pan/tilt
movement.
Each keyboard uses a separate RS-232 port connection. Model
1981 Port Expanders can be used to connect four keyboards to
each 1996R CPU RS-232 port, to provide a maximum of 40
keyboards for control of the 2050 system.
Model 2096 Alarm Interface Units and 2010DBVL Video Loss
Detection Buffer Modules can be connected to the control
ports to provide alarm or video loss event inputs to the 1996R
CPU. A control port can be configured to send output
messages to a serial RS-232 printer for all such events.
An external computer can be connected to a RS-232 port for
transmission of the ASCII-coded commands for 1996R system
control (see Appendix, page A-10), or for uploading or
downloading system setup information using the optional, PC-
based, 2050SW13 software.
