Overview
Thank you purchasing your American Fibertek N-111 Net I/O. Please take a few minutes
to read these installation instructions in order to obtain maximum performance from this
product.
The AFI V’NES (Video Network Enterprise Solution) N-111 device allows serial data and
contact closure signals to be made accessible on and linked over a network, with N-111
devices acting as transparent bridges to link together customer equipment. This permits
contact closure signals – such as door opening sensors, alarm buttons, or motion
detectors – to be linked to remote alarm annunciation, or serial data sources such as key
pads or card registers to send data to a remote monitoring system. N-111 devices can
be linked together over a standard Ethernet connection, making it possible to use a preexisting LAN or the Internet for device communication.

Connecting the Hardware
Connecting power
The N-111 has a two position screw terminal which accepts input from an external
12VDC power supply. To connect an external power supply, use two wires, 16-28 AWG
in size. Strip about ¼” of the insulation from the end of the wires before inserting them
into the terminal block. Tighten the terminal screws to secure the wires in the terminal
block. Be sure that the polarity of the applied power is as indicated. Connecting power
with incorrect polarity may damage the N-111.
The N-111 is also capable of being powered over the network connection through
802.3af Power over Ethernet (PoE). To power a N-111 over POE connect one end of an
Ethernet cable to the N-111’s Ethernet port and the other end to a PSE network switch,
midspan injector, or similar device capable of providing power over an Ethernet
connection in accordance with the 802.3af POE standard. When used in this
configuration the DC power input terminal block should not be connected to a power
supply.
Connecting to the network
Connect one end of an Ethernet cable to the N-111’s Ethernet port and the other end of
a cable to the Ethernet network.
10
Connecting a serial device
The N-111 has a DB-9 serial port which can be configured in software for several
different communications modes. The method used to connect to the serial port will
vary depending on the hardware mode selected.
Connecting RS232
To connect the N-111 to a RS232 serial device, connect a serial cable from the serial
port on the rear of the N-111 to the serial device. The N-111 RS232 is configured as a
DTE device.
Connecting RS485 four-wire
To connect to a serial port in RS485 4-wire mode, you will need a DB9 connector wired
as indicated. Four connections will need to be made for the two data transmit lines and
the two data receive lines. Do not make any other connections to any other pins on the
DB9 connector.
Connecting RS485 two-wire
To connect to a serial port in RS485 4-wire mode, you will need a DB9 connector wired
as indicated. Two pairs of pins on the DB9 will need to be bridged together. Two
connections will then need to be made to the bridged pins for the two bidirectional data
lines. Do not make any other connections to any other pins on the DB9 connector.

Connecting contacts
The N-111 has a port for contact input (alarms) and contact output (aux). This port is a
five pin header with a supplied plug with screw terminals. Customer connections to the
contact port are made by securing stripped wire ends into the screw terminals.
Note: All connections to the screw terminals should be made with the terminal plug
removed from the unit, and with power disconnected from any customer equipment
being connected to the terminals.
Connecting an alarm input
The contact block has two terminals which are used as an alarm/contact input. Viewing
the rear of the N-111, these two terminals are the two on the left side of the contact
block. These terminals are intended to be connected to customer equipment which will
make or break a connection between the two terminals, such as a door open switch or
motion detector contact output. It can be designated through the configuration web page
if an alarm condition will correspond to the connection being made or the connection
being broken.
To connect an alarm source such as a door switch or motion detector to the N-111, use
two wires, 16-28 AWG in size. Strip about ¼” of the insulation from the end of the wires
before inserting them into the terminal block. Tighten the terminal screws to secure the
wires in the terminal block.
Alarm Input Connection
Note: the electrical connection to the alarm inputs are to be connected only to isolated
contact closure devices, and must not be directly connected to any external power or
ground source. Directly connecting either terminal of the alarm input to any voltage
source or external ground may damage the N-111.
Connecting a supervised contact
In supervised contact mode a 1K resistor is connected in series with the contact closure.
This resistor should be located at or close to the contact device, so that short circuits
across the contact lines will be detected. A valid contact closure will be registered only
when the resistance across the contact input lines is measured to be exactly 1K.
13
Connecting an aux output
The contact block has three terminals which are used for the aux contact out function.
(location details). The contact output is a form C contact closure. (terminal details)
To connect an external device to an aux contact out on the N-111, use two wires, 16-28
AWG in size. Strip about ¼” of the insulation from the end of the wires before inserting
them into the terminal blocks. Tighten the terminal screws to secure the wires in the
terminal block.
Aux Contact Out
When an output is not active, the Common terminal will be electrically connected inside
the N-111 to the Normally Closed terminal. When the output becomes active, the
connection between the Common terminal and the Normally Closed terminal will be
broken, and a connection will then be made inside the N-111 between the C terminal
and the Normally Open terminal.
The Aux Output terminals are electrically isolated from the N-111 and from each other,
and can be safely connected to external power sources or grounds.
14
LED indicators
Within 5 seconds of the AC power cable being connected, the N-111 will perform a test
of its front panel indicator LEDs. The LEDS will first light green, then red, then turn off.
Once the sequence has finished the LEDs will resume their normal function and the unit
will be ready for use.
The front panel of the N-111 has several LED indicators. The action of individual LEDS
is as follows:
Power indicator LED
This LED indicates that power is applied to the unit. During initial powering up of the
unit, the power LED will briefly flash green, then red for a moment. It should then light
green and remain green while the unit is on.
Status LED
This LED indicates the status of the aux contact output. During initial powering up of the
unit, this LED will briefly flash green, then red for a moment. It will then be illuminated
green if the aux contact output is active, or off when the aux contact output is not active.
Alarm LED
This LED indicates the status of the alarm input. During initial powering up of the unit,
this LED will briefly flash green, then red for a moment. It will then be illuminated red if
the alarm input is active, or off when the alarm input is not active.
Serial LED
This LED indicates the status of the serial port. During initial powering up of the unit, this
LED will briefly flash green, then red for a moment. During operation, this LED will flash
green when serial data is being transmitted out of the serial port, red when serial data is
being received into the serial port, and off when there is no port activity.

Factory default IP
The N-111 is factory programmed with the following default network settings:
IP address
192.168.10.11
Netmask
255.255.255.0
Gateway
192.168.1.1

If the N-111 has not had its IP address changed by the user it will be possible to connect
to it at this network address. If you do not know the IP address of the unit, you can reset
the unit back to factory defaults and then connect at the default address.
