Adjusting network settings
Once you have connected the subsystems to the network drivers, in the node tab
of the linked network subsystem, you can adjust some specific parameters that de-
pend on the type of connection.
Serial links require defining the COM port, the baud rate and other parameters re-
lated to the physical data link. The ISO1745 protocol also allows fine tuning the
traffic control: message rate, sample time, and status request timeout (see Tab.1).
Parameter
Meaning
Notes
Message rate
Traffic threshold (messages per sec.)
above which the status requests are de-
layed for limiting the impact on the net-
work.
Default value is 5. Large Cerloop may need
a lower value, e.g. = 3.
Fast links may tolerate higher values, up to
20.
Sample time
Period of time for evaluating traffic rate.
Default value is 10. Smaller values will
speed up the Sample time - used only for
fast networks.
Status request
timeout
Max delay before starting a new status
request, even without having properly re-
ceived the end message of the previous
request.
Default is 30. It may be decreased for
speeding up specific technical tests.

ISO1745 traffic control parameters
In general, MK8000 can communicate with…
The MK7022, CK11, and FG700A interface using the NS 8010 driver for
ISO1745 protocol at 1200 or 2400 (recommended) baud.
Note
: the vitality check is required for CK11 and FG700A (see 4.7 below).
The GW20, GW21, NK822x using the NS8012 driver for CMSDL protocol at
4800 or 9600 (recommended) baud.
The NK822x over LAN/WAN using the NS8210 driver for CMSDL/IP or CEI79
protocol.
The NK8225 over LAN/WAN using the NS8011 driver for BACnet/IP protocol.
The SI410 over a serial RS232 line using the NS8014 driver for Sintony protocol
(9600 baud 8N1 recommended).
The FC330A over a serial RS232 line using the NS8015 driver for CNDL proto-
col.
The SiPass access control system using the SiPass driver for LAN protocol.
Video devices using the Video Network Manager for LAN video protocols.
