CONNECTIONS
All connections to the 1996R CPU are made on the rear panel
of the unit, illustrated in Figure 1-2.
Data Line Connections
Two data line outputs on the rear panel of the 1996R CPU,
labeled DATA LINE 1 and 2, are provided to transmit
switching and control instructions to the 2050 system bays.
• DATA LINE 1 is used to control video switching for a
maximum of 1024 video inputs to video outputs 1 to 64.
• DATA LINE 2 is used to control video switching for a
maximum of 1024 video inputs to video outputs 65 to 128.
Data Lines are looped through the input and the output
switching bays of the 1900 Series MegaPower, or 2050 Series
MegaPower II Matrix Switching Bays. Refer to the
Installation Manual for the appropriate Switching Bays for
instructions and illustrations of interconnection of these units.
The Data Line 1 output also provides control information for
camera site Receivers to control pan/tilts, motorized lenses,
auxiliaries, and presets at the site. The 2091 Code Generator
can be used to convert this data to Control Code or RS-232
code for control of American Dynamics Receivers. Data Lines
are looped through the 2091 units in a similar manner as the
2050 switching bays.
Use 75-ohm video cable with BNC connectors for all data line
connections. The last bay or unit in both chains must be
terminated in 75 ohms at the Data Line Out connector (use a
75-ohm terminator).
See the Appendix for typical connections from the 1996R CPU
to the 2050 Switching Bay and 2091 Code Generator.
Programming Monitor Connection
All the features of the 2050 system are programmable through
on-screen menus generated by the 1996R CPU. The menus are
displayed via a separate video output BNC, labeled PROG
MON, located on the rear of the 1996R CPU. This video
output may be connected to a separate monitor or connected
back into the video switching system for display on any system
monitor.
Use 75-ohm video cable with BNC connectors. The PROG
MON video output line must be terminated in 75 ohms.
Control Port Connections
Ten 8-pin, modular RJ45 control ports, labeled PORTS 1
through 10, are provided on the rear panel of the 1996R for all
RS-232 control communications. See RS-232 Connections,
page 1-4, for connections to these 1996R control ports.
Each of the ten control ports may be programmed for a specific
use (such as keyboard, alarm, video loss, printer, or terminal)
via the Ports Menu, page 4-20.
• The 1996R CPU receives control and alarm inputs from
keyboards, external computers, alarm interface units, or
video loss detection modules via the control ports.
• The 1996R CPU can transmit ASCII-coded, printable
messages to a serial, RS-232 printer via one control port.
• System setup data can be uploaded and/or downloaded via
an RS-232 control port using the optional PC-based
software package, 2050SW13.
Each port is configured to receive ASCII commands via RS-
232 protocol and is programmable for baud rate, number of
data bits, number of stop bits, and parity. As shipped, all
1996R control ports are configured for Keyboard operation at
1200 baud rate, 8 data bits, 1 stop bit, and no parity.
Each port may be interfaced to four control sources using 1981
Port Expanders.
