NT132 System Overview
History
Radio Frequency Identification (RFID) systems have existed for
many years. Initially, systems were developed so that military aircraft
and ships could be quickly identified by electronic methods. Radio
equipment (transponder) on a plane or vessel would broadcast a
coded signal to identify it as a friend to an appropriate receiving
station. A plane or vessel not able to transmit the correct
identification would be considered a possible enemy. Similar
technology is employed today for air traffic control as well as vessel
identification in shipping lanes and ports – and the RF device is still
called a transponder.
Other present-day applications include “tagging” vehicles, assets or
people for identification within a designated area – or as they pass
through portals. For example, a transmitting device can be placed on
a laptop computer so it can be identified if carried out of a building.
Further, if people in that building also carry transmitting devices, it is
easy to ascertain not only that the computer left the building – but
that it was not carried by the person to whom it was assigned!
Obviously, such technology has quickly found its way into disciplines
such as vehicle entry, fleet management, inventory control, and
controlled access to buildings or other areas.
NT132 System Components
The following diagram (Figure 3) shows a very basic AXCESS NT132
system. The system has the following components:
• A Reader to send radio signals to a transmitting antenna,
receives radio signals from a receiving antenna and outputs the
data to some device – a computer or a Wiegand control panel,
for instance.
• A transmitting antenna to “wake up” any Tags in the area.
• An Antenna Tuning Unit (ATU) placed between the Reader and
the Antennas to properly tune the transmitting antenna to its
surrounding environment.
• Tags to receive wake-up radio signals and broadcast their IDs to
the receiving antenna. Tags can be carried by individuals, placed
on equipment or in vehicles.
• A receiving antenna to intercept radio signals from the Tags and
to pass the signals to the Reader.
• One or more of the following: a computer for data storage, a
peripheral device such as a light, buzzer, door strike, gate

controller, camera, etc., and/or a control panel that accesses a
computer or a device.
An NT132 system may be as simple as a single Reader and Bar
Antenna controlling the front door of a small office or it may comprise
a network of interconnected devices and Readers controlled by a
computer.

NT132 System Overview
A Tag is a very small transponder (transmitter + responder) that
remains in a sleep state (off) until awakened. When the Tag receives
a special wake-up signal from the Reader, the Tag will wake up (turn
on) and emit a radio signal of its own. The signal emitted by the Tag
is typically its pre-programmed identification number – but could
include other data as well. The signal is generally used for detection,
identification and location of people or objects.
An AXCESS Tag, encased in black or beige plastic, is about the size
of a credit card and is approximately 200 mils thick. Some Tags have
slots to attach personnel ID pictures to them. Other Tags may be
attached permanently to vehicles or assets such as computers.
Types of Tags
The typical types of Tags are:
Passive Tags
A passive tag does not have an on-board power source (battery). It is
powered from the antenna radiation field of the transmitter that is
trying to wake the tag up. It uses the same antenna for transmitting
and receiving.
Active Tags
An active tag has its own battery and is capable of a greater transmit
distance (range) than the passive tag. An active tag only has a
transmitting antenna. It is common for active tags to continually
transmit and the system will only report those tags in the reception
field.
AXCESS Tags
AXCESS Tags, based on AXCESS NeuroTag technology, are a
hybrid of active/passive and do not respond until awakened. The tag
is in a “sleep” state that requires almost no power until the tag is
activated. AXCESS Tags receive on a low frequency and transmit on
an ultra high frequency.
The Tag checks the wakeup signal for proper modulation and a
Reader ID code, then transmits its own ID number along with the
Reader ID that woke it up.

NT132 System Overview
Reader
The Reader (Figure 4) originates the signal that is broadcast to wake
the Tag. The Reader has the following purposes:
• Encode a transmission wake-up signal and transmit it via the
antenna to the sleeping Tag.
• Decode the signal from the Tag via the receiving antenna. The
Reader will convert the data to a format usable by a computer or
Wiegand control panel for further processing of the information.
• Output data to a control device or a computer.
Figure 4 AXCESS Reader – external view
Types of Readers
Serial
This Reader communicates using the EIA-232 standard, more
commonly known as RS-232C. It can connect to a communications
port on a computer or any device that can accept RS-232C data.
Wiegand
Wiegand Readers output Security Industry Association (SIA) 26-bit
data to Wiegand control panels. It connects to the Wiegand control
panel by three wires – Data One, Data Zero and Ground.
Free Topology Transceiver (FTT)
FTT Readers can be used to create networks of Readers. They
communicate with a computer using Echelon LonWorks
control external devices via TTL controls.

Antennas
NT132 System Overview
Because the Tags receive and transmit at different frequencies,
different antennas are used for each leg of the communication.
Antenna construction is related to the wavelength (or fraction thereof)
of its design frequency. Antennas designed for the Ultra High
Frequency spectrum (to receive the transmit signal from the Tag) can
be quite short. Antennas designed for Very Low Frequencies (to
transmit the wake-up signal to the Tags) must be quite long. The
transmitting antenna is a loop and the receiving antenna is a dipole.
Types of Ant ennas
For interior use, antennas can be inconspicuously mounted – for
example, hidden in a false ceiling or disguised as a common picture
frame. Also, depending on type of installation, the transmitting
antenna and receiving antenna may be combined into a single
enclosure or may be built as separate units.
Road Loop and Dipole Antennas
The Road Loop and Dipole Antennas are used for identifying Tags in
vehicles. The Road Loop Antenna is installed in the road surface and
sends out wake-up signals. The Dipole Antenna is separate from the
Road Loop Antenna and is mounted so that it can receive
transmissions from the Tags.
Bar Antenna
The Bar Antenna has both transmitting and receiving antennas
enclosed in a box that is approximately 2 feet long, 5 inches wide and
1 inch thick. It can be inconspicuously mounted above or next to a
door or above the ceiling tiles.
Swing Frame Antenna
The Swing Frame Antenna has both transmitting and receiving
antennas built into its frame. The antenna enclosure is designed as a
picture frame so that it may be mounted unobtrusively on walls.

NT132 System Overview
Antenna Tuning Unit (ATU)
An Antenna Tuning Unit or ATU (Figure 5) maximizes the signal
transmission from the Reader. It is installed between the Reader and
the transmitting and receiving antennas.
Figure 5 AXCESS ATU – external view
On the bottom of the ATU, there are two jacks to connect to the
transmitting and receiving antennas and two jacks to connect to the
Reader.
Types of ATUs
There are two kinds of ATUs currently provided. Although they
require different methods of optimizing performance, they perform
the same function.
Toggle Switch ATU
This ATU has a toggle switch, a rotary switch and a voltmeter. The
antenna performance is tuned by toggling one switch between three
positions and turning the other switch among ten positions. The
voltmeter indicates when the optimal setting has been reached.
Jumper ATU
This ATU has eleven 3-pin headers and five LEDs. The antenna
performance is tuned by moving jumpers on the headers. Optimal
performance is indicated by the strength of the LEDs.

Reader Types
Serial Reader
This type of Reader can interface directly with the communications
port of a computer or another control device that process standard
EIA-232 serial data.
Wiegand Reader
This is type of Reader outputs standard SIA 26-bit Wiegand data and
is used when interfacing with a standard Wiegand controller.
Required Materials
For each Tag read, the Reader outputs data every 750 milliseconds.
Duplicate Tag information is stored in the Reader’s buffer for 12
seconds so that redundant Tag reads are ignored during the this time
interval.
FTT Readers
FTT (Free Topology Transceiver) Readers are for installations
involving a network of Readers connected to one another. This is
accomplished via twisted-pair wiring over a total distance of up to
8,800 feet. FTT Readers can also control devices according to data
sent over the network by the host computer.
The following materials are necessary for a successful installation:
• Power drill and bits
• Screwdrivers – Phillips and flathead
• 4 # 10 Anchors, Plastic (for mounting in drywall or mortar)
• 4 # 10 Self threading screws
• 4 # 10 Washers
• Depending on the surface that the Reader will be mounted on,
you may need #10 molly bolts.

• Each Reader type has it own required materials for connecting to
third-party devices. Please see the specific section for the
Reader that you are installing.
Mounting the Reader - All Types
All Readers have the same mounting requirements.
IMPORTANT! Before permanently mounting any piece of the
AXCESS NT132 System, first lay out and test the entire system.
Step 1: Select a Reader location consistent with the type of
antenna being installed. The Reader should be a minimum
of 36 inches off the ground, preferably at eye-height.
Step 2: Mount the Reader securely with the cover hinge on the left
and external connectors on the bottom (Figure 6). Screw
holes are provided inside the cabinet for mounting to a wall
(Figure 7).
IMPORTANT! When you mount the Reader, be careful not
to damage the electronic components. A manual
screwdriver is recommended for tightening the screws.

Step 2: Open the Reader case and disconnect the BNC connector
running from the Transmitter card at the TX connector
(Figure 6). This will give you access to the terminal block
underneath.
Step 3: Loosen the white terminal block by unscrewing it. This will
give you access to the terminals.
Step 4: The ground connection protects against any differential in
voltage potential at each ground plane that may cause
current to flow between the external panel and the Reader.
Such a condition could damage and/or impact the
performance of either or both units.

Reader Installation
Run the ground wire from the Ground connection at the
Wiegand control panel to the G terminal on the Terminal
Block (TB1, see Figure 8) in the Reader. For standard
Wiegand control panels, the Ground wire is black. Ensure
that the termination is secure, but not over-tight. Route
cables through the conduit chase at the bottom of the
Reader.
Step 5: Run the Data One wire from the Wiegand control panel to
D1 on the Terminal Block. For standard Wiegand control
panels, the Data One wire is white.
Step 6: Run the Data Zero wire from the Wiegand control panel to
D0 on the Terminal Block. For standard Wiegand control
panels, the Data Zero wire is green.
Note: If Data One and Data Zero are connected
backwards, the data will be garbled.
Step 7: Screw the white terminal block down.
Step 8: Reconnect the TX cable connector.
Step 9: Ensure the Wiegand control panel is wired correctly.
Step 10: Enter the Tag numbers into the panel’s database
according to the panel manufacturer’s instructions.

Figure 9 FTT Reader system
The FTT Reader System has at least one of each of the following:
• An FTT Reader that can connect to several external devices and
to other FTT Readers.
• A computer to drive the system. The computer collects data from
the tags. The computer may also send commands via the
Readers to other devices that control doors, send alarms, turn on
lights, etc.

Reader Installation
• A Serial Gateway that coverts the computer’s RS-232 data to
LonWorks data and vice versa. LonWorks is the protocol used to
communicate with the FTT Readers. The Serial Gateway
transmits data from the computer to the Readers via twisted pair
wire. Up to thirty-one FTT Readers can be connected to the
Serial Gateway.
Note: Although the Serial Gateway has a terminal block, it cannot
directly control any access devices. Do not wire access devices to
the Serial Gateway.
Required Materials
• Unshielded twisted pair wire to run between Readers. The type of
cable chosen affects the cable distances allowed in the FTT
network. The recommended cable lengths are given in the next
section.
• Belden 85102, 16 AWG, single twisted pair, stranded 9/29,
unshielded, plenum
• Belden 8471, 16 AWG, single twisted pair, stranded 9/29,
unshielded, non-plenum
• Level IV, 22 AWG, twisted pair, typically solid and unshielded
• TIA 568A Category 5, 24 AWG, twisted pair, unshielded. This
cable type is recommended because it allows for upgrades.
• Sensitive trigger, TTL relays to drive door strikes or other devices
(for example, Altronix RBSN-TTL or Alarm Saf RBKS-124P)
• 22 AWG wire, max four feet in length, to connect the FTT
Readers to the relays.
• Wire as specified by device manufacturers to connect the
devices to the relays.
• An RS-232C straight-through cable with a DB9 male connector to
connect the Serial Gateway to a computer.

Level IV 1312 feet (400 m) 1640 feet (500 m)
Category 5 820 feet (250 m) 1475 feet (450 m)
Max Node to Node Distance
The distance from each Reader to all other Readers on the network
must not exceed the maximum node-to-node distance. If multiple
paths exist, e.g., a loop topology, then the longest path should be
used for calculations (Figure 10).
Max Total Wire Length
Maximum total wire length is the total amount of wire connected per
network.

Reader Installation
Connecting the Serial Gateway to the PC
Step 1: Connect the male DB9 end of the straight-through serial
cable to the female DB9 connector at the bottom of the
Reader.
Step 2: Connect the other end of the serial cable to the PC.
Step 3: The Serial Gateway has pads so that it can be placed on
top of or next to the PC.
Step 4: Configure the communications port settings on the PC as
follows:
Baud 2400
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
The Serial Gateway is a DCE (Data Circuit-terminating
Equipment) device, and data is output through a DB9
female RS-232 connector. Only the following pin
assignments are used:
• Transmitted Data (pin 2)
• Received Data (pin 3)
• Signal Ground (pin 5)
Connecting the Serial Gateway to an FTT Reader
Step 1: Prepare a sufficient length of twisted pair wire to connect
the first Reader to the Serial Gateway.
Step 2: Insert the twisted pair wire into the terminal block labeled
FTT in Figure 11 in the Serial Gateway and run it out the
conduit chase.
Step 3: Run the twisted pair through the conduit chase of the
Reader and insert the twisted pair wire into the FTT
terminal block. You can connect up to four Readers by the
FTT terminal block in the Serial Gateway; however, we
recommend connecting only one or two. You can network
up to thirty-one Readers together by twisted pair wire.
Connecting FTT Readers to Each Other
Step 1: Prepare a sufficient length of twisted pair wire to connect
the two Readers.

Step 2: Insert the twisted-pair wire into the terminal block labeled
FTT (Figure 11) in the first Reader and run it out the
conduit chase.
Step 3: Run the twisted pair through the conduit chase of the
second Reader and insert the twisted pair wire into the
FTT terminal block. Each terminal in the FTT terminal
block can hold up to four wires, depending on gauge.
Note: When connecting Readers to each other, remember that
shorter cabling makes for a better network because it improves
transmission.
Connecting an FTT Reader to a Device
The FTT Reader has two outputs to control devices. These outputs
can be found on the FTT Terminal block (Figure 11).
The terminals in the FTT terminal block are for the following:
Label Purpose
24V 24V for powering the TTL relay
Gnd Ground for the TTL relay
Door Strike Trigger output with a 20 mA source/sink
capability for triggering sensitive trigger relays.

IMPORTANT! Do not use the Door Strike and Secondary Output
terminals to drive relay modules directly. Such relays require 100 mA
or more, well in excess of the FTT module’s source power capacity.
The FTT card can burn up. Using sensitive trigger, TTL relays (for
example, Altronix RBSN-TTL or Alarm Saf RBKS-124P) is
recommended.
NOTE: The rolled-up serial cable connected to the RS-232 connector
is for configuration and diagnostics. The FTT Reader cannot be
converted to a Serial Reader.
