The DigiReader Series is a family of Digital Proximity Readers
          
(DigiReaders). (Graphic representations of the DigiReader Series—not to scale— are shown in “Figure 1: The Different DigiReader#p#分頁(yè)標(biāo)題#e#
          
Models” on page 1-2.) DigiReaders are bi-directional securitydevices that read digital credentials, (from either side of the sensor),at ranges from 1 to 20 inches (2½ to 51 cm), depending upon themodel and the environmental conditions. DigiReaders are used withthe NexSentry 4100, 4102, 4104, Star I and Star II (4100 Series),SE818SC and SE422 Access Control Units (ACUs), with the ACUseither operating as stand-alone devices or operating in conjunctionwith a StarGaze (SG), a NexSentry Manager (NSM), a NexSentry
          
Command Center (NSCC), an SE6000, or an SE5850, NexWatch
          
Access Control Host System. Connection between a DigiReader andan ACU is over the NexWatch proprietary S-NET interface or over aWiegand interface to a Wiegand ACU. (The Wiegand data can beeither 26- or 34-bit Wiegand standard.) (Also included in the
          
DigiReader Series is a keypad-only reader, the DR4200K, which isthe only family member available with the analog SE818SX ACU.)

DigiReaders emit a low-level 132-kHz field. When a digital
          
credential (card, KeyMate™, etc.) is placed in this field, a digitalchip embedded in the credential uses the field’s energy for
          
activation. Once activated, the credential responds by broadcasting a70-kHz signal, modulated with a credential-specific code sequence,
          
back to the reader. The reader receives this signal and converts it to adigital code which is then sent to the ACU, (the Controller). The
          
Controller identifies the digital credential according to its code andmakes either an access granted or an access denied decision, basedon credential information stored in the Controller's database or thehost system's database.
          
The DR4205K has a keypad on the face of the DigiReader. Thekeypad is used to enter the user’s Personal Identification Number
          
(PIN). The DR4205K keypad version can be configured forcredential-only use, or keypad-only use, or both.
          
DigiReader Set Up for 818SC, 4100-Series or Star I ACUs
          
The 818SC, 4100-series or Star I ACUs set the use parameters viathe ACU DOOR Command. If the S-NET Reader Type entry is set to
          
DKR, the credential use will be activated for that door; set to NONE,the credential use for that door will be de-activated. For the same
          
door/reader combination, if the VIP Enable is set to Yes or No, thekeypad portion will be activated or de-activated, respectively.
          
The DR4200K is a keypad-only reader look-alike of the DR4205K,activated from the ACU DOOR Command by setting VIP Enable(for that door) to Yes.

LED (and Beeper) (S-NET Operation)
          
All DigiReaders have a single three-color (red-amber-green) LED
          
controlled by the Access Control Unit (ACU) to which theDigiReader is attached. “Figure 3: LED Locations for the Different
          
DigiReader Models” on page 3-4 shows the location of the LED oneach of the DigiReader models.
          
With the DigiReader on line to an ACU and with power applied, (theready state), the DigiReader's LED will be a constant red. When a
          
DigiReader is configured to read digital credentials only (with nokeypad part of the DR4205K or VIP2 or DR4200K activated for thesame door), a valid credential will produce a momentary amber
          
LED, followed by a green LED for the door unlock time or until thedoor is closed following the credential-holder's access; (the LED willthen return to the constant red). With a keypad also activated, theamber LED will continue until either both the valid digital credentiaand valid PIN, in either order, have been read/entered, producing thegreen unlock time LED, or until the PIN grace period has been

• The microcontroller uses a synchronous technique to sample the
          
incoming data bits and shift them into a 48-byte data buffer. The
          
data collection and reporting techniques are key-type dependent.
          
The reader alternates between the two key types as follows:
          
• Key type 1 (NexWatch QuadraKey™, NexKey™, 2Smart™, and
          
KeyMate™).
          
For 50 msec the key message data is serially shifted into a buffer
          
while searching for an 88-bit PSK key message signal in
          
NexWatch format. The received key data is validated if it
          
contains:
          
• the proper 8-bit preamble,
          
• a 32-bit reserved field,
          
• a 32-bit keycode field,
          
• a valid mode character,
          
• a valid parity character,
          
• a valid checksum byte, and
          
• the receive buffer contains two identical 88-bit key messages.
          
....Reporting as an S-NET DKR-type, only the key ID is reported to

Revision E, Part Number 6600025 DigiReader Series 42XX 3-9
          
• Only one keycode is received and reported at a time. A 1-second
          
timer is started when a key is read to prevent the same key from
          
being repeated too quickly.
          
DR4201 and DR4208S Operation (26-bit and 34-bit Wiegand Mode)
          
• The RF field is powered at all times.
          
• A digital key is received in the same fashion as for the S-NET
          
operation. (See above).
          
• If the key is in 88-bit NexWatch format, then either the 32-bit (or
          
26-bit) keycode is immediately transmitted via the data 0 and data

• If the key is a 48-bit type then the key content is checked to
          
determine if 26-bit, 35-bit or 37-bit data is to be sent. If the
          
content cannot be determined then no message is sent.
          
• Only one keycode is received and reported at a time. A 1-second
          
timer is started when a key is read to prevent the same key from
          
being repeated too quickly.

For the NexSentry Star I, Star II and 4100 Series ACUs, theDR4205K reader has two modes of operation, the Normal Mode andthe KeyPad-Credential (or KP-Credential Mode). Address switchSW1, ( the upper byte of the address), determines mode selection. IfSW1 is set to 0 or 8, the Normal Mode is selected. If SW1 is set to 4,#p#分頁(yè)標(biāo)題#e#
          
5 or 6, (or C, D or E), the KP-Credential Mode is selected.

Setting Normal Mode
          
With address switch SW1 set to 0, the DR4205K operates in itsnormal mode. Address switch SW2 is then set to the physicalReader/Door address of the DR4205K: 1 through 9 and A through F,(for DigiReader addresses 1 through 15). See “Table 7: DR4205KNormal Mode Settings, SW1 & SW2” on page 3-10.(With both address switches SW1 and SW2 set to 0, a DigiReader isoff-line.)

Operational Characteristics of Normal Mode:
          
• DKR portion only enabled: the credential is sent as a credential,
          
and no PIN is expected.
          
• VIP portion only enabled: the PIN is sent as a PIN. No
          
credential is expected.
          
• Both DKR and VIP portions enabled: the credential is sent as a
          
credential, the PIN is sent as a PIN. Both the credential and the
          
PIN are expected (in either order).
          
Setting KP-Credential Mode
          
With address switch SW1 set to 4, 5 or 6, the DR4205K operates in
          
its 'KP-Credential' mode. In the KP-Credential Mode the DigiReader
          
operates in a special manner if only the DKR portion or the VIP
          
portion of the DigiReader is enabled: see Operation in KPCredential
          
Mode, below. The number of digits in the KP-Credential
          
is determined by the 4, 5 or 6 of address switch SW1. Address
          
switch SW2 determines the physical Reader/Door address of the
          
DR4205K for nodes 1 to 15. See “” on page 3-13.
          
For the physical S-NET addresses 1 through 9, set switch SW1 to the
          
S-NET values and switch SW2 to the number of KP-Credential
          
digits, 4, 5 or 6. For Reader/Door addresses 10 through 15, set
          
switch SW1 to A through F and switch SW2 to the number of KPCredential
          
digits 4, 5 or 6.
          
Deselecting either the DKR or VIP portion requires powering off and
          
on (or issuing a RESET command in the terminal mode) to establish
          
the deselected state.

Cable Preparation:
          
1 Route the data and power cable to the DigiReader location and
          
prepare the cable for attachment to the DigiReader.
          
2 Remove two inches of the plastic jacket and the shielding foil from
          
the cable.
          
3 Strip each wire back 1/4" for connecting to the DigiReader.
          
DR4200K, DR4203, DR4205 Series, DR4208S & DR4220 Installation:
          
1 The S-NET cable on the DigiReader may be routed from the back,
          
bottom or the side of the DigiReader. The reader is pre-configured
          
for cable installation through the back mounting plate.
          
NOTE: S-NET cable is routed directly through the back on the
          
DR4203, DR4208S, and DR4220, and, from the back, on the side on
          
the DR4205GM DigiReader only, (see “Figure 4: Cable Routing
          
Configurations” on page 4-2 and “Figure 14: DR4205GM: Placement#p#分頁(yè)標(biāo)題#e#
          
of Decal & Reader onto Glass” on page 7-6), and on the back, through
          
the gap made by removing the plastic notch on the DR4200K,
          
DR4205, DR4205E, and DR4205K DigiReaders.

remove the plastic notch from the bottom of the cover. A rattail file
          
may be used to enlarge the opening (see “Figure 4: Cable Routing
          
Configurations” on page 4-2).
          
3 The DR4208S DigiReader cable is designed to be routed in two
          
ways. The unit comes from the factory with the cable, secured by a
          
'SW-NE' strap, routed through the hole in the middle of the upper left
          
quadrant (looking at the back of the unit). Alternately you can reroute
          
the cable through the bottom notch, (removed as in paragraph
          
2, above) by opening the case, carefully removing the PCB (four
          
screws), snipping the 'SW-NE' strap, securing the cable with a 'W-E'
          
strap, (via the holes provided for this purpose in the PCB), and reassembling
          
the unit.

• Switch SW1 is used to select the special reader modes of
          
operation, (as shown in “Table 12: Valid Settings - DR4200K,
          
4203, 4205 SW1 & SW2” on page 5-5). SW1 is set to 0 (factory
          
default setting) for S-NET operation and F for Wiegand operation.
          
• Switch SW2 is used to set the Reader/Door address, and, with
          
SW1 set to F, for additional options, including (SW2 = A or B) the
          
Wiegand number of bits. SW2 has a factory default setting of 1,
          
but it may be set to any address from 1 to F (15). A 16th
          
DigiReader address is provided by setting switch SW2 to 0 and
          
switch SW1 to 8 (for Normal Mode), or C, D or E (for DR4205K
          
PIN/Credential Mode - see “Table 12: Valid Settings - DR4200K,
          
4203, 4205 SW1 & SW2” on page 5-5).
          
Valid addresses may be limited by the controller. (Please see the
          
appropriate controller manual.)

The S-NET is an RS485 serial network for communication between
          
the Controller and node devices. Typically, the cable used is two
          
twisted pairs with an overall shield; one pair is for data, the other pair
          
is for DC power. Terminate the last S-NET device with a 120-ohm,
          
¼ watt resistor or termination jumper as shown in “Figure 7: S-NET
          
Wiring” on page 6-1. The maximum S-NET length is 4000 feet
          
(1200 meters).

(Note that up to two AD4305 NexStar RS485 Multiplexers may be
          
used to simplify wiring and extend a network.)
          
Where a pigtail cable is provided with the reader, a splice is required
          
and the installer should, if possible, keep the splice within 3 feet of
          
the reader, to allow splice inspection at the reader location.
          
The type of cable used for the S-NET should be separate twisted-pair
          
(data and power). See “Table 11: Recommended S-NET Cable” on
          
page 5-3 for NexWatch recommended S-NET cables.

Use care when choosing the installation site. To avoid possible
          
external sources of RF interference, do not locate the unit near
          
motors, pumps, generators, DC-AC converters, AC switching relays,
          
light dimmers, or any other devices that emit an electronic radar
          
frequency. Do not locate the unit within 10 feet (3 m) of a computer
          
terminal.
          
For the mounting of the DR4201 reader, see “Special Mounting
          
Location: DR4201 Reader” on page 7-2.
          
The DR4203, which is designed to be mounted on a metal door
          
mullion, is the only reader that is specifically designed to be
          
mounted on metal. Metal in the vicinity of any of the other devices#p#分頁(yè)標(biāo)題#e#
          
can reduce the read range. In general, as the amount of metal in
          
close proximity to the device increases, the reliable maximum read
          
range decreases. For optimum operation, ensure that a DigiReader
          
has a minimum of 6 inches (15 cm) clearance at the rear and
          
surrounding sides, as shown in “Figure 9: Mounting DR4205, 4208S
          
Near Metal: Best Read Range” on page 7-2. Never cover the front
          
of the DigiReader with any type of metal.
          
To obtain the maximum performance from the DR4220 reader,
          
mount the reader at least 10 inches away from any conducting metal.
          
Use the method appropriate to the mounting surface material; if
          
required, use sealing compound to maintain water-resistance.

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . TESTING THE DIGIREADER LOCATION 8
          
If you suspect the presence of RF interference at a location where#p#分頁(yè)標(biāo)題#e#
          
you plan to install a DigiReader, you should check the site prior to
          
mounting the DigiReader unit. The presence of RF interference may
          
affect a DigiReader in two different ways:
          
• If RF interference is present, the DigiReader unit may exhibit
          
.............false reads (or 'ghost' reads), i.e., the unit may beep and the
          
.............LED illuminate, with no access credential present.
          
• Alternatively, with RF interference present, the DigiReader
          
............unit may read an access credential inaccurately, slowly, or
          
............even may be prevented from reading the credential.
          
The following procedures will make it easier for you to identify a
          
suitable location and to position the DigiReader to minimize any RF
          
interference:
          
1. The DigiReader models DR4200, DR4203, and DR4205 (all

........switches on the DR4203 and DR4205 to FF for the test mode.
          
........The DigiReader models DR4201, DR4208S, and DR4220 have
          
........a five-position dip-switch for the address. Set all five dip-
          
........switch positions to ON for the test mode. Then perform the
          
........following steps:
          
• Connect only the S-Net wires which provide power, (DC
          
............positive power and the DC return, and the grounding shield),
          
............between the DigiReader and the controller.
          
• Hold the DigiReader against the installation surface.
          
• Verify that there are no cards or other credentials in the area
          
............capable of being detected by the reader. (A credential in your
          
............pocket, or somewhere-else where it can be detected, could be

............the source of any beeping, so you must be sure this is not the
          
............case.)
          
• If you are sure no credentials are present and the reader beeps,
          
............then there is RF interference present, causing the beeping.
          
............(The number of beeps is an indication of the degree of
          
............noisiness: more beeping indicates a more noisy environment
          
............than less beeping.)
          
• Keep testing locations until you find one where no false or
          
............'ghost' reads occur.
          
2. With no false or 'ghost' reads occurring, and with the reader still
          
........in test mode, present a credential to the reader . The reader
          
........should now beep, indicating that the card has been read. (If the
          
........reader does not beep when the card is presented, there may be a
          
........source of RF present blocking the reading of the card. In this
          
........case also, keep trying new locations,)
          
• With the credential reading correctly, verify the read time and
          
............the maximum read distance.
          
3. When a suitably quiet location has been identified, (relatively#p#分頁(yè)標(biāo)題#e#
          
........free from RF noise), connect the DATA A and DATA B wires
          
........between the DigiReader and the Access Control Unit.
          
• Set switches SW1 and SW2, for the DR4203 and DR4205
          
............models (or, for the DR4201, the DR4208S,or the DR4220,
          
............the 5-position dip-switch) to the correct address. With the
          
............controller now physically connected to the S-Net, and the
          
Using “Table 1. DR 4201, 4203, 4208S, 4220, 4200K
          
Specifications” on page 2-1 or “Table 2. DR4205, 4205GM,
          
4205K Specifications” on page 2-2, you can determine the
          
reader’s capability with your chosen credential type(s). This same
          
performance is what you would expect once the system is
          
completely installed.

Field troubleshooting methods fall into three categories: 1. power
          
problems; 2. communication errors; 3. communication failures.
          
“Table 16: Troubleshooting” on page 9-1 lists the most common
          
symptoms for these conditions and provides suggested actions to
          
identify and get the system (back) into running order.
