Network Control Module 300 Series Technical Bulletin 12
Table 3: N1 LAN Cards
Card Description
ARCNET
Card
ARCNET LAN communication is provided by a standard ARCNET card (Ordered separately.
See Specifications and Order Codes for more information.) connected into ISA Bus Slot 1
(Figure 1: Callout 4).
Ethernet
Card
An Ethernet card (Ordered separately. See Specifications and Order Codes for more
information.) connected into ISA Bus Slot 1 (Figure 1: Callout 4) of the NCM350 allows you to
connect the Metasys system directly to an Ethernet network. This allows you to communicate
with other devices on the Ethernet LAN, without the use of an Ethernet Router. Metasys
system functionality is the same on both the Ethernet and ARCNET LANs.
Note: You can use either an Ethernet or an ARCNET card in a single NCM350. If you wish
to have both ARCNET and Ethernet connections, you must use the ARCNET LAN and
connect to Ethernet using the Ethernet Router. For details, refer to the Metasys Ethernet
Router Technical Bulletin (LIT-6295035).
You cannot do smoke control on an Ethernet network where UL 864 is required. See the
Smoke Control Restrictions section of the Smoke Control Technical Bulletin (LIT-636330).
LONWORKS
Network
The L
ONWORKS network allows communication between the Metasys network and
L
ONWORKS compatible devices using the LONWORKS compatible interface cards as follows:
NU-NET201-0 DX-9120 controllers on N2E Bus (N2E-TP78)
NU-NET202-0 DX-9121 controllers on N2E Bus (N2E-FTT10)
NU-NET203-0 L
ONWORKS compatible devices (requires Metasys Release 10.0 or later
software) (LON-FTT10)
NU-NET203-1 L
ONWORKS compatible devices (requires Metasys Release 11.00 or later
software) (LON-FTT10)
The L
ONWORKS interface card must be inserted in Slot 2 (Figure 1, Callout 5) of the NCM.
The L
ONWORKS network carries all communication between the NCM and the DX-912x or
L
ONWORKS compatible devices and between the devices themselves. The types of data that
are transferred across the network include:
commands from the NCM to the devices
automatic reporting of alarms and change-of-logic states from the DX-912x to the NCM (N2E
Bus only)
responses from the devices to the NCM, including identification and requested data values
complete databases for the DX-912x controllers (N2E Bus only)
time synchronization message from the NCM
analog and binary point data shared between devices
To meet FCC and CE standards for the N2E Bus installation, install ferrite clamps and beads.
For detailed information, refer to the L
ONWORKS N2E Bus Technical Bulletin (LIT-6364100).
Media
Interface
Board
The Media Interface Board (MIB-OWS) is a communication card that allows the Fire-Net
NCM to be connected to the Metasys Intelligent Fire Network. Insert the MIB-OWS in the
second ISA slot (Figure 1: Callout 5). Detailed information on setting up the NCM as a
Fire-Net NCM can be found in Appendix A: Fire-Net NCM of this document.
Serial Card
A non PnP serial card can be placed in either ISA slot to allow direct connection of a printer
or OWS. See Table 11 for details.
Note: The serial card for Port 5 or Port 6 must be a 16-character FIFO (First-In, First-Out)
serial card. The serial card must use a 16550AF UART or equivalent. An example of a
16550AF serial card is the SIIG Model IO-1809. The card cannot be a PnP device.
Internal modems are not recommended for use with NCM300s unless
the PnP feature can be disabled. Most new internal modems are PnP,
which is not compatible with NCM300s.
