Fig. 4 Connections and unit addressing
In order to communicate with DF8000 unit(s), the NK822x should be configured to
handle DF8000 lines, using the CMX-DL protocol.
More than one DF8000 line can be connected to a single NK822x by using sepa-
rate COM ports. The multi-drop configuration allows connecting multiple DF8000
systems to the communication line.
The maximum distance of the RS485 line is to 1200 meters at 19200 baud (baud
rate may have to be slowed down in particular conditions) . A 100 Ohm resistor is
recommended at both ends of long lines, see section 4.4.
Composer configuration
DF8000 units can be configured by all Composer software versions in the same
way as specified for CF9000 (DF8003 can substitute for CF9003 module).
DMS8000 software MP4.15 and later includes a specific DF8000 model that can
profit of the improved characteristics of DF8003 (fastest baud rate). See also Tab.3
below.
Composer version Models
Up to MP4.10 CF9003 and DF8003

Tab.3. Configuration of CF9003 and DF8003 module in Composer
All DF8000 devices as well as the related NK8000 interfaces must be configured in
the Composer project as described in the Network, Fire, and Intrusion Connectivity
guide (document no. A6V10062425). Using the Composer menus and tools, the
configuration settings should then be downloaded to the NK822x.
Note that not all the combination of I/O modules can be configured in a DF8000
unit. Refer to the Annex B on page 36 for a complete list of the valid DF8000 con-
