Pelco Manual C573M-D (11/03) 45
Figure 37. Simple System Configuration
• Figure 44 illustrates a non-Coaxitron setup that includes an MDA connected to a 9760
keyboard, CM9760-CC1 CPU, and CM9760-MXB matrix bay. The MDA accepts the
master time and date from the CM9760-CC1; therefore, the MDA must be set to slave
mode.
• Figure 45 illustrates a Coaxitron setup that includes a System 9760 connected to an
MDA. The MDA accepts the master time and date from the CM9760-CC1; therefore,
the MDA must be set to slave mode.
• Figure 46 illustrates a CM6800 connected to an MDA. The MDA accepts the master
time and date from the CM6800; therefore, the MDA must be set to slave mode. (The
MDA can also accept the master time and date from the CM6700.)
• Figure 47 illustrates an MDA that accepts message text from third-party equipment.
The third-party equipment connects to a COM port (COM 1 or COM 2) of the MDA
using the RS-232 or RS-422 communication standard. For cabling requirements, refer
to the
Data Connections
section of this manual. For information about COM port DIP
switch settings required for RS-232 and RS-422 communication, refer to the
Commu-
nication Ports Setup
section of this manual. For a wiring diagram of the MDA using
RS-232 communication, refer to the
Connecting the MDA to an External PC
section of
this manual. For information about MDA COM port pinouts using RS-422 communica-
tion, refer to Table D in this manual. Note that when connecting the MDA to third-party
equipment using RS-422 communication, TX+ must connect to RX+ and TX- must
connect to RX-. For information about support of message text insertion by the MDA,
refer to the
Set Message Text
section of this manual and to Appendix C.
NOTE:
As illustrated in
Figures 45 and 46, the MDA
can be used with Coaxitron
products such as the
CM9760-CXTA, CM6800,
and CM6700. Note that the
MDA must be placed
after
the Coaxitron equipment. If
the MDA is placed incor-
rectly, camera control may
be adversely affected.
