2.0 Proximity - Principle of Operation
Proximity, also known as Radio Frequency Identification (RFID), is a method of
reading a card or tag without requiring any physical contact between the card/tag and
the reading device. With proximity readers there is no physical wear and tear on the
card/tag or the reading device. No inserting of a card/tag into a reader slot or swiping
of a card/tag through a reader slot is required. The card/tag is simply held up to a
reader, within the reader's detection range. Refer to Figure 2-1 for a diagram of this
process.
In a proximity reader application, a continuous 125 kHz electromagnetic field is
radiated from a coil inside the reader. This field is called the "excitation signal." When
a card/tag is presented to a reader, a coil inside the card/tag picks up the excitation
signal from the reader generating a small current in the card/tag's coil. This current
powers a small integrated circuit (IC) within the card/tag that holds a unique
identification number.
The coil in the card/tag transmits this identification number using a 62.5 kHz
electromagnetic field, one-half the value of the excitation signal. This 62.5 kHz signal
acts as an analog RF carrier for the digital ID number and is called the "receive signal"
as the coil in the reader receives this signal.
The reader passes the signal on to the RF receiver in the controller for decoding where
it is processed, error checked, and converted to a digital signal. The receiver then
sends the digital signal with the ID number to the microprocessor in the controller
where an access decision is made.
The read range for a key tag is approximately one-half that of a card. This is due to the
size of the coil in the tag compared to the coil in the card. Since the coil in the tag is
smaller, it needs to be closer to the excitation signal to activate the IC within the tag.
The bigger the coil in the card, tag, or reader, the greater the read range is likely to be.

should be determined by the current draw requirements of the Wiegand device and the
actual length of the cable run. A +5 VDC Wiegand device must have +5 VDC at the
device (long cable runs have a voltage drop across the length of the run due to the
resistance in the cable). To ensure +5 VDC is available at the device a larger gauge of
wire (having less resistance) or a separate power supply at the Wiegand device may be
required.

The TWAIN drivers that control communication between many digital cameras
and the badging software are not compatible with the Windows NT 4.0 operating
system. Alternate methods of digital image transfer may be necessary.
6.0 System Cautions
6.1 Earth Ground
You should make a quality earth ground connection to the PXL-250 controller to
ensure the best possible operating conditions for the controller. Without a quality earth
ground connection, the access control system may appear to operate correctly, but will
be extremely susceptible to transients and electromagnetic interference on data and
power lines. An earth ground brings all electrically neutral lines to the earth's surface
potential (essentially to a zero potential) providing three primary benefits to the PXL250 controller.
1. An earth ground protects the PXL-250 controller from electrical transients such as
power surges and lightning strikes (also providing a degree of safety for an
operator).
2. An earth ground provides a path to ground for electrical interference minimizing
data and communication problems for the reader data and network communication
lines.
3. Through a feature on the PXL-250 controller the shield for the entire RS-485
network is automatically grounded at one point on the master controller
minimizing communication problems.
Here are some possible sources for an earth ground.
• copper shrouded ground rod
• cold water pipe (must be a metal pipe - not PVC)
• steel building framing member (if the building's frame is embedded in the earth)
• electrical system ground (at the breaker/fuse box)
• telephone system ground
6.2 Electromagnetic Interference
Electromagnetic interference is electromagnetic energy radiated by an electrical
device that may affect the operation of other electrical devices. The PXL-250
controller can be sensitive to electromagnetic interference (EMI), affecting the
controller's performance. To ensure the best operating conditions for the controller,
please review and consider the following suggestions.
6.2.1 Power Supplies
Switching power supplies are known sources of EMI and cannot be used as the VDC
source for the PXL-250 controller or for any proximity reader.
Page 22 P/N: 01836-004 Revision 5.5
Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293
Only commercially built, linear, regulated power supplies should be used with
any access control system using proximity readers.
When installing a power supply for the PXL-250 controller, mount the power supply
three feet or greater from the controller to provide a degree of isolation from EMI that
may be generated by the power supply.
6.2.2 EMI Sources
Keri Systems also recommends installing the controller in low EMI areas whenever
possible. Always be cognizant of sources of EMI that may affect the operation of the
PXL-250 controller and install your controller away from these sources. Common
sources of EMI include computer monitors, electric motors, power transformers, and
air conditioning and heating units.
6.2.3 Separating Power Cables from Network and Reader Cables
To prevent EMI that may be conducted between power cables and network/reader
cables, Keri Systems recommends running the power cables apart from the network
and reader cables. This will minimize the possible effect a voltage surge on the power
cable may have on the network and reader cables.
6.3 Transient Suppression
Voltage transients are electrical surges or spikes conducted through power, input, or
output lines. Transients are generated when electric devices (such as electric locking
devices) are turned on or off. Transients may affect the operation of both the PXL-250
Controller and SB-293 Satellite board. Because of this, transient suppression is
required for both devices. A transient suppressor is a device added to an electrical
circuit that minimizes the affects of transients. Depending upon the application, a
transorb or an isolation relay provides the suppression necessary to ensure proper
operation of the access control system.
Under normal circumstances, a 1.5KE39C transorb must be installed across the
positive and negative power lines at the electric locking device to provide the best
operating conditions for the PXL-250 or SB-293. This transorb will minimize any
transients that may be generated by an electric locking device from affecting the
operation of the PXL-250 or SB-293. Two bipolar transorbs are provided with each
PXL-250 and each SB-293 for this purpose.
In applications such as parking gates or turnstiles (or any application using a large
electric motor), a transorb alone may not provide enough suppression; an isolation
relay may be required. Keri Systems offers an Isolation Relay Package (Keri Systems
P/N IRP-1) which can provide suppression for the large transients generated by these
types of devices.

Technical Reference Manual – PXL-250 and SB-293 Keri Systems, Inc.
6.4 Communication with the Host Computer
6.4.1 PC COM Port
A COM port is a hardware device that allows a computer to communicate with
external devices. To ensure proper communication between the access control system
and the PC, the PC's COM port must be configured properly and be operating
correctly. Most communication problems between PC and access control system are
directly attributable to an improperly configured or inoperable PC COM port. Please
ensure the PC COM port is working correctly before loading the Doors access control
software on your PC system.
Keri Systems cannot be held responsible for problems using the Doors access control
software that are due to an inoperable COM port. To assist in verifying basic COM
port operation, Keri Systems has provided a basic COM port test with the Doors
software package. COM port test instructions can be found with the documentation
supplied with the Doors software.
NOTE: Doors software only supports COM ports 1, 2, 3, or 4.
6.4.2 Ethernet TCP/IP
Ethernet connectivity is achieved by connecting the Entraguard master controller to a
LAN-100 Ethernet Module allowing the Entraguard network to be attached to a Local
Area Network (LAN) instead of directly to a computer. This gives any workstation on
a LAN (with the proper authority) the ability to communicate with the Entraguard
network.
Ethernet modules must be assigned an unique IP address which must be entered in
Doors for proper communication. One Ethernet module is necessary for each master
controller.
Utilizing Ethernet technology requires expertise. A LAN/WAN administrator or other
network professional is necessary. For further information please refer to the LAN/
WAN Ethernet Communication Application Note (P/N 01881-001). Keri Systems
does not provide technical support on network issues, please see your network
administrator for assistance.

Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293
7.0 PXL-250/SB-293 System Installation
7.1 Advance Planning
A successful, easy to maintain installation requires advance planning - making sure the
site has everything necessary for a successful installation and making sure that all
materials are placed in easily maintainable locations that take advantage of the
features the PXL-250 access control network has to offer.
7.2 Utility Requirements
A successful installation needs:
• grounded power outlets for the PC system and controller power supplies
• dedicated analog telephone lines if communication between access control
network and PC is to be done via modem - one for the host PC system and one for
each master PXL-250 controller
NOTE: In most cases, modems are not compatible with private branch exchange
(PBX) telephone switching systems causing disconnection problems with the modem.
For this reason, dedicated analog telephone lines are required for successful modem
communication.
7.3 Where Should Controllers be Installed?
Controllers should be accessible for ease of installation and ease of maintenance.
Service closets may be a viable installation location. Controllers can be mounted
centrally, or distributed across an access control network.
7.3.1 Central Mounting
Central Mounting places all controllers in one location, running lengths of cables out
to each door to support the needed readers, inputs, and outputs. The benefit to central
mounting is that all controllers are together in one location making it easier to
maintain and secure the controllers. The drawback to central mounting is that it tends
to use more cable, routing cables from the controller to each door for the reader and
the necessary inputs and outputs. Accordingly, the cable costs for central mounting is
higher. Also, reader cable lengths are limited to 500 feet making central mounting in a
large installation difficult, if not impossible.
Revision 5.5 P/N: 01836-004 Page 25
Technical Reference Manual – PXL-250 and SB-293 Keri Systems, Inc.
7.3.2 Distributed Mounting
Distributed Mounting places a controller near each door. The RS-485 network
communication cable is then routed to every controller on the access control network.
The benefit of distributed mounting is that less cable is needed for the reader and the
necessary inputs and outputs as they are all near the controller. Only the network cable
needs to be routed throughout the installation. The drawback to distributed mounting
is that a location needs to be found near each door for every controller. More effort
may be needed to maintain and secure the controllers.
All controllers need to be mounted in environmentally suitable locations. They require
protection from weather and from temperature/humidity extremes. If a PXL-250
controller is to be used outdoors, it must be installed in a watertight, weatherproof
enclosure. All controllers need at least three feet of separation between the controller
and the controller's power supply. This will prevent EMI radiated by the power supply
from affecting the performance of the controller.
7.4 Installing the Enclosure
The PXL-250 controller enclosure may be installed on any kind of wall material:
wood, sheet-rock, concrete, or metal. Mount the 12 VDC power supply for the PXL250 controller three feet or greater from the controller to provide a degree of isolation
from EMI that may be generated by the power supply. Always be aware of sources of
EMI that may affect the operation of the PXL-250 controller and make your
installations away from these sources whenever possible.
The enclosure's mounting holes are found at each corner of the unit (top left, top right,
bottom left, and bottom right). To mark a surface for drilling enclosure mounting
holes, simply place and hold the enclosure in the desired location and with a pencil or
scribe place a mark on the mounting surface at each mounting hole. Note the location
of the enclosure's knockouts (circular, removable plates on the enclosure's base plate)
and remove the knockout that allows you to route your cables into the enclosure in the
easiest, most direct path.

7.5 The Enrollment Reader
The enrollment reader is the "A" reader on the master controller on the access control
network. The Doors access control software expects all card enrollment by
presentation information to come from the "A" reader on the master controller. For
ease of card enrollment, the enrollment reader and master controller should be
physically near the host computer running the Doors software.
The enrollment reader can be a Keri proximity reader or a Wiegand compatible device
reader. An enrollment reader is not necessary if all cards are block enrolled (block
enrollment uses the identification number printed on the body of the cards for
enrollment information so cards are not presented to an enrollment reader – block
enrollment assumes that the identification number on the card bodies are in
consecutive order).
The enrollment reader can be used at a door for access control as well as enrollment.
However, during the enrollment process the door or doors assigned to the master
controller become unavailable for access control; these doors remain in the state they
are in when the enrollment process begins (you may consider manually unlocking the
door before beginning enrollment and then relocking it when enrollment is complete).
Further, if the master controller has both "A" and "B" readers, it is possible for an
existing cardholder to present an already enrolled card at the B reader while an
operator is enrolling a card at the A reader. In this case, the card read by the B reader
will generate a "Card Already Enrolled" error message and the cardholder will not be
granted access through the door because the controller is in enrollment mode. For
these reasons, an installer may consider reserving the master controller and one reader
for card enrollment only.
7.6 Where Should Cables be Routed?
The PXL-250 controller offers flexibility in cabling options between optimizing cable
costs versus controller access/convenience. However there are several things to keep
in mind when routing cables for an installation:
DO
• Route cables in accessible areas whenever possible. This will make cable/system
maintenance easier.
• Add transient suppression across electric devices attached to the PXL-250 and SB293 output relays.
• Use an isolation relay (Keri Systems P/N IRP-1) if connecting to a parking gate,
turnstile, or any application using a large electric motor.
DO NOT
• Do not route cables near EMI sources. Cables can act as antennas, receiving EMI
that can affect controller performance.
• Do not stretch cables or route them over sharp edges.

7.7 RS-485 Networking
The PXL-250 uses a half-duplex, RS-485 communication bus. This is a very robust
system and has been tested to exceed standard RS-485 industry specifications. Using
approved cable and good installation practices, the network will operate satisfactorialy
with up to 16,000 feet of cable for systems of up to 128 PXL-250 controllers, each
with an SB-293. The following rules apply when wiring the controller network
communication bus.
1. The total network cable length cannot be greater than 16,000 feet.
2. Controllers can be connected in a single-run multi-drop, a star, mulitple stars, a
continuous daisy chain, etc.
3. The master controller can be located at any point in the network.
4. Care must be take to ensure the Tx- and Tx+ lines are not cross-wired.
5. Shield integrity must be maintained throughout the network installation.
6. If there are more wires than will reliably fit into the PXL-250 terminal block, Keri
recommends using an external terminal strip to combine the cables and then
connect a single wire to the terminal block.
7. The recommended cable is Belden 9501 or its equivalent. This is a single-pair,
twisted, shielded, AWG 24 cable.
Please refer to the PXL-250 Network Wiring Application Note (P/N 01824-002) in the
Appendix for detailed information on extended network configurations.
NOTE: Keri Systems defines a "Star" pattern as multiple sets of daisy chained
controllers all connected to the master controller at the center of the star.
NOTE: Communication buses such as RS-485 often appear to work even if installed
incorrectly, but can have intermittent problems making problem diagnosis difficult.
Failure to properly install an RS-485 network can result in network communication
errors and can cause the access control system to lock up. Although Keri Systems has
lab tested the functionality and data integrity of the extended network configurations,
no guarantees can be given for extended network configurations.
7.8 PXL-250W Jumper Settings
NOTE: Early revisions of the surface mount PXL-250W mislabeled the JP4 jumper as
JP5. All instructions for the JP4 jumper apply to the jumper labeled as JP5 (see
Figure 9-1 on page 39 for the location of the jumper).
On the PXL-250W controller (for use with Wiegand readers), there is only one jumper
that may require setting. JP4 sets the power supply voltage with which the controller
powers the reader (see Figure 7-1 on page 29 and Figure 9-1 on page 39).
Page 28 P/N: 01836-004 Revision 5.5
Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293
All Keri Systems proximity readers use 5 to 12 VDC power (except for the MS-9000
which uses 12 to 24 VDC power) while most Wiegand compatible readers use just 5
VDC power. For Wiegand configured PXL-250W controllers, there is a reader power
warning LED on the controller board to indicate if the controller is applying 12 VDC
to the Wiegand compatible reader (see Figure 7-1 on page 29). If your Wiegand
compatible reader does operate on 5 VDC no changes need to be made, the default
position for the jumper is to set power to 5 VDC. If your Wiegand compatible reader
requires 12 VDC, perform the following steps to set the reader supply voltage to 12
VDC.
When power is applied to the controller, the RDRPWR (reader power) warning LED
will turn on (see Figure 7-1) indicating 12 VDC is being supplied to the Wiegand
compatible reader.
JP4 - Wiegand Reader Power Supply Voltage
• Jumper across JP4 pins 1 and 2 to enable 12 VDC power for readers.
• Jumper across JP4 pins 2 and 3 enables 5 VDC power for readers. Most Wiegand
output devices require 5 VDC. This is the factory default setting for PXL-250W
controllers (to help ensure that 12 VDC is not accidentally applied to 5 VDC
Wiegand readers). If your Wiegand compatible reader requires 12 volts, move the
jumper from pins 2 and 3 to pins 1 and 2.
Figure 7-1: Setting the JP4 Jumper on PXL-250W Controllers
NOTE: Applying 5 VDC to a 12 VDC reader will not damage the 12 VDC reader.
However, applying 12 VDC to a 5 VDC reader very likely will damage the 5 VDC
reader. Be sure you are applying the correct supply voltage to the reader. Keri
Systems cannot be responsible for 5 VDC readers damaged by excessive voltage.

7.9 SB-293 Jumper Settings
On the SB-293 satellite board, there is only one jumper that may require setting. JP12
configures the satellite board for either second door control or for general purpose
inputs and outputs (see Figure 7-2, and Figure 10-1 on page 71).
• Placing a Jumper across JP12 pins 1 and 2 configures the satellite board for
general-purpose inputs and outputs.
• Removing the Jumper across JP12 configures the satellite board for second door
control with additional inputs and outputs. When the satellite board is configured
for second door control, the primary door must be connected to the "A" reader
(TB-5 on the PXL-250 controller board) and the secondary door must be
connected to the "B" reader (TB-6 on the controller board).

7.10 Installing the SB-293 Satellite Board onto the PXL-250 Controller
Perform the following steps to install an SB-293 satellite board onto a PXL-250
controller.
1. Turn the controller's power OFF.
2. Line up the upper left-hand corners of the satellite and controller PCBs.
3. Line up the stand-offs in the top two corners of the satellite PCB with
corresponding mounting holes in the controller PCB (see Figure 7-3 on page 31).
4. Align the Satellite Board to Motherboard connector pins.
5. Gently press the two boards together with each stand-off into its mounting hole
and with the connector pins meshing together.
6. Turn the controller’s power ON.
7. If the J2 and P2 connectors have been meshed together properly, the LED on the
SB-293 (see Figure 10-1 on page 71) will turn green.
