Installation Instructions

Model NCC-2F

Network Interface Card
For PCI Application with Windows

OPERATION

The Model NCC-2F from Siemens Industry, Inc. (as
shown in Figure 1) is a PCI-compliant network card
used with the NCC, NCC WAN and Desigo CC sys­tems. The NCC-2F allows the user to interface net­worked MXL and/or XLS fire panels to Desigo CCs
and/or NCCs on XNET. The NCC-2F can also provide
an interface to NCC WAN components, including the
HUB-4 over HNET. An NCC-2F can provide connectiv­ity to either XNET or HNET, or both XNET and HNET
using 2 cards. The NCC-2F may also be used in an
FVNET setup inside the VNT. This allows for interfac­ing HNET and XNET between multiple XLS systems.

The NCC-2F provides the NCC and Desigo CC with a su­pervised RS-485 network connection. The NCC-2F oper­ates in both Style 4 (Class B) and Style 7 (Class A) modes.

The module fits in any available PCI 5V compliant slot. The
card is keyed so that it will only fit in an appropriate PCI slot.
The module comes preinstalled in NCC and Desigo CC
computers. Hardware installation instructions for the NCC­2F, when it is not factory installed, can be found in the

Physical Installation section of this document.

Controls and Indicators

The NCC-2F provides one reset switch and four LEDs that
are accessible through the back of the PC it is mounted
in. The reset switch (S2) is located just below TB1.
Pushing the reset switch initializes the NCC-2F operation.

The LEDs are located above TB1 and are, in top to bot­tom order:

CONFIGURATION

The NCC-2F is assigned to a standard COM port by
Windows when the drivers are installed. The drivers
come pre-installed in NCC and Desigo CC computers.
The NCC-2F driver installations are covered in the

Driver Installation section of this document.

The COM port assigned to the NCC-2F can be viewed
in the Windows Device Manager. One NCC-2F card
occupies two consecutive COM ports, but only one will
be available for use by the NCC-2F. On Windows XP
systems, the used COM port will be the first (or lower)
numbered port assigned for the NCC-2F card. On Win­dows 7 systems, the used COM port is the NCC-2F
Enhanced Communications Port assigned as Port0
(seen via Properties) - and may be the lower or higher
port number, depending on the computer.

The Device Manager is accessible in Windows as follows:

WINDOWS XP

Click Start >Settings >Control Panel >Administrative
Tools >Computer Management >Device Manager.

Another way is to right click My Computer icon, then
select Properties >Hardware >Device Manager.

Figure 2 shows a sample Windows XP Device Manager
view and a typical assignment of COM ports on a PC
with (2) NCC-2F boards installed. The port assignments

for the NCC-2F are labeled PCI Communications Port.

WINDOWS 7

Open the Start menu, then click on Control Panel; this
will open a new window on the Desktop, showing the
Control Panel options.

The Address bar of the Control Panel window should
end with the “Control Panel” location, followed by a
“right-arrow”.

Click on the “right-arrow” to display the available addi­tional locations, then select All Control Panel Items,
and click on it. On the updated screen, select Device
Manager and click on it.

Figure 3 shows a sample Windows 7 Device Manager
view and a typical assignment of COM ports on a PC
with (1) NCC-2F board installed. The port assignments
for the NCC-2F are labeled Enhanced Communication
Port, once installed.

In these examples above, the first NCC-2F is assigned
to ports COM3 and COM4, and the second NCC-2F is
assigned to ports COM5 and COM6. This is the default
setup, with XNET on COM3 (the first port of the first
board) and HNET on COM5 (the first port of the second
board).

The NCC or Desigo CC XNET (and HNET) port as­signment can be changed to agree with any port assign­ment at the time of install or update. Either board can
handle XNET and either board can handle HNET. There
is no difference in the boards. However, XNET and
HNET are different protocols, so HNET wiring should
go to the board with the COM port assigned to HNET
and, likewise, XNET wiring should go to the board with
the COM port assigned to XNET.

PHYSICAL INSTALLATION

Remove all Windows PC power before installation.

To install the NCC-2F in a computer in which it is not
factory installed, follow the steps listed below:

1. Unscrew the two knurled knobs on the rear of the
NCC or Desigo CC computer (computer enclosure
may have different physical characteristics.).

2. Slide the cover back an inch or so and lift it off.

3. The NCC-2F installs into any free PCI 5V compliant
slot in the computer. Select a slot and remove the
blank cover, keeping the screw.

4. Remove the terminal block from the NCC-2F by
removing the two screws that hold it to the bracket.

5. Place the NCC-2F into the open slot so that the
NCC-2F card edge extends through the opening in
the back of the PC.

6. Align the NCC-2F with the card edge connector in
the computer and press it firmly into place.

7. Secure the NCC-2F by installing the screw that
held the blank cover. (Refer to Step 3.)

8. Replace the computer cover and tighten the
knurled knobs (or equivalent).

9. Reattach the terminal block by sliding it onto the

O NOT US

s

NCC-2F card edge and install the two screws. This
is a keyed connection and will only install one way.

10. After the NCC-2F is installed, install the NCC-2F

drivers following the instructions in the Driver
Installation section of this document.

ELECTRICAL CONNECTIONS

Network (XNET)

The XNET connections are made on terminals 1-4 of the
terminal block on the rear of the NCC-2F. The primary
pair (or network A) is on terminals 1 and 2. The second­ary pair (or network B) is on terminals 3 and 4.

For Style 4 networks, install a 120 ohm EOLR on ter-

minals 3 and 4. See Figure 4 for wiring details.

For Style 7 networks, connect to both the primary and

secondary pairs. See Figure 4 for wiring details.
