Network Control Module 300 Series Technical Bulletin 29
Port Configurations: Migration Functionality
Table 13 illustrates applications and port restrictions when
downloading one of the Migration Functionality software sets; for the
Network Port application, see the Network Port Technical Bulletin
(LIT-6295050).
Table 13: Migration Functionality Serial Port Configurations
Port Application
(Ports must be configured via system software for appropriate
application.)
N2 (Port 1)
N2 Bus (RS-485) connections
Integrated RS-232 Port
(Port 2)
All devices connect to the integrated RS-232 port via RS-232 cable.
S2 Migration, connected via RS-232 to JC/85 trunk via TableTop Modem.
JC/85 Gateway, connected via RS-232 to JC/85 headend. (Connection may
alternately be via a high-speed modem over a dedicated phone line.)
Integrated RS-232 Port
(Port 3)
Configured OWS (defined in the database)
Printer
Unconfigured OWS (not defined in the database): An example is a laptop computer
used to run logs and summaries, or to download a database.
NT Port (Port 4)
Network Terminal directly connects to the RJ-12 port via the NT cable.
ISA Slots
Configured OWS, Direct or Dial-up (defined in the database)
Printer, Direct or Dial-up
Direct or Dial-Up OT
L
ONWORKS devices (Slot B only) connected using LONWORKS network connected to
the L
ONWORKS interface card.
MIB-OWS must be placed in Slot B, NU-NCM300-FIRE/NU-NCMFIRE-1 only.
N1 LAN (must be placed in Slot A, either Ethernet or ARCNET may be used, but
not both.)
Notes: JC/85 Gateway: To send the NCM print file to the JC/85 printer, define the printer as Port 2, the
same port definition assigned to Gateway. To print to a printer connected directly to the NCM, connect the
printer into an available port, such as Port 3 integrated RS-232 port.
Operator Terminal: To send a Change-of-State (COS) to the Operator Terminal, a printer must be defined on
Port 0. (Prior to Release 8.0, Port 3 was used for this purpose.)
NCM Cable Guidelines
This section describes and illustrates the network connections.
This section also describes and illustrates cable connections to
Ports 2, 3, and 4 by device (such as by OWS, printer), and by
migration type (Gateway or S2).
N2 Bus (Port 1)
This three-wire termination accepts RS-485 signals via the N2 Bus
(see Figure 6). For further details about making N2 Bus connections,
refer to the N2 Communications Bus Technical Bulletin (LIT-636018).
To add a second N2, make connections to Port 2 of the NCM using a
MM-CVT101 (RS-485 to RS-232 converter).
