Pelco Manual C573M-D (11/03) 5
Figure 1. System Configuration (Rear Panel View)
The MDA can be programmed using a PC or a CM9760-KBD, KBD200A, or KBD300A
keyboard. Each of the 16 video inputs can be individually programmed to insert time/date
and title information on each video output, and each video output is selectable to include or
exclude time/date and title generation. Character positions are adjustable horizontally and
vertically on-screen with digital brightness control. Programming also includes cable
compensation for up to 1,500 feet (457 m) of RG59/U coaxial cable.
The MDA can act as a stand-alone time/date and title generator or can be synchronized to
a System 9740
™
/System 9760
®
as a matrix time/date and title generator:
• As a stand-alone unit, an MDA can be addressed to provide the master time and date
for up to 63 MDA slave units.
• When connected to a System 9740/System 9760 CC1 port, up to 64 MDAs can accept
the master time and date from the 9740/9760.
In addition, note the following about the MDA:
• Using the RS-232 or RS-422 communication standard, the MDA can accept text
messages from third-party equipment. A message can contain up to 24 characters. Up
to five lines of messages can be displayed simultaneously. The messages can be
inserted onto any video channel independently. For additional information, refer to the
Set Message Text
section of this manual.
• All video inputs are individually ground isolated to prevent ground loops, eliminating
the need for ground loop isolation transformers.
• Battery backup protects programming information for a minimum of one year.
• The MDA does not pass Coaxitron
®
signals; however, the MDA can be used with
Coaxitron products such as the CM6700, CM6800, and the CM9760-CXTA.
