The Cypress Handheld Reader System with OSDP Secure Channel protocol: A wireless handheld credential reader
which interfaces with the access controller through the reader's matched Base Unit, using an encrypted wireless link.
The Handheld Reader is a portable proximity card reader that connects wirelessly to the access control panel. The
Base Unit connects to the access control panel similar to a standard Wiegand reader and the access control panel
validates the credentials. The Base Unit is able to provide an Access Granted or Access Denied response after a
credential is presented. The Handheld Reader and Base Unit do not store any credential data. There are three types of
Dual-lane kits: HHR-4156B (one reader), HHR-4256B (2 reader), and HHR-4356B (3 reader).
Advantages of OSDP Secure Channel Protocol
Application Protocol Integrity and Confidentiality Controls: !
OSDP Secure Channel-compliant handheld units and base stations protect the integrity, confidentiality, and
authenticity controls of all messages transmitted across the network.!
Protocol Replay Protection:
Resilient against replay attacks, using a rolling Message Authentication Code to ensure no two messages appear the
same as transmitted over the network, and no two identically received messages are accepted.!
Handheld Reader Authentication State Linked to Authentication Attempt:
No message from the base station (or from an attacker) can cause the user interface to signal authorization without first
having transmitted credential data to the base station. !
Protocol Does Not Leak Sensitive Data:
The OSDP specification relies upon an inherently secure connection to perform initial key exchange, using a default
key defined in the specification. This is done with randomly generated keys, at the the factory. The keys are not stored
by Cypress.!
Authentication Method Diminishes Efficacy of Brute-Force Attack: !
The authentication method implements rate limiting, allowing one attempt per 5 seconds to diminish the efficacy of a
brute-force attack while maintaining system responsiveness during normal use. The base station and handheld unit
firmware do not accept repetitive badge presentations to prevent rogue hardware from searching badge space for
authorized IDs.!
Communication Security Does Not Rely on Protocol Secrecy: !
Implementation of the Security Industry Association’s Open Supervised Device Protocol (OSDP) eliminates the
system’s reliance on protocol secrecy. This protocol is well known and widely accepted in the access control industry
as the solution to data security in physical access control.
HHR-4X56B Dual-lane Kits - Overview

HHR-4X56B Dual-lane Kits - Wireless Communication and Encryption
OSDP Secure Channel Encryption:!
Each HHR-8056B reader has its own OSDP Secure
Channel session with the HHR-8400 base. Each of these
OSDP Secure Channel sessions is encrypted with its own
encryption key.
Radio Level Encryption:!
The radios in all of the HHR-8056B readers and the
HHR-8400 base encrypt all of data being transmitted
between the readers and the base. The radio level
encryption uses AES128. The readers and the base share
an encryption key for the radio level encryption.

HHR-8056B Readers
Arrows show all wireless
devices sharing the same
radio level encryption key.
Arrows show all three
readers and the base
have individual OSDP
Secure Channel sessions,
each with their own
encryption key.
Wireless Communication
The wireless radios in the HHR-4000B readers and base units use the IEEE 802.15.4 standard for mesh networking.
The HHR readers and base units form ad-hoc mesh networks, which do not require additional external infrastructure
(such as WLAN) to function.!
The communication protocol between HHR-4000B devices over the air is the Open Supervised Device Protocol
(OSDP). OSDP is an IEC standard (IEC 60839-11-5). This protocol uses the AES-128 cipher in CBC mode for both data
confidentiality and message authenticity. !
Wireless Encryption
The HHR-4000B devices wireless communication utilize two layers of encryption. The first layer of encryption is on the
radio link layer, which uses AES-128 to encrypt data packets between the radios in the Handheld readers and the Base
Unit. The second layer of encryption is on the protocol level, which uses the OSDP Secure Channel protocol to encrypt
the OSDP messages sent between the Base Unit and the Handheld Readers.

Unpacking!
•Remove packaging from units and check interior of Base Unit for any shipping damage.!
•Inventory any included parts (depending on model), shown below.!
•Locate any terminal connectors, manuals / quick-starts, and warranty information.
IMPORTANT SAFETY INSTRUCTIONS AND WARNINGS For LiPo BATTERIES
It is important to specifically use a Lithium Polymer/Li-ion charger only. Do not use a NiMH or NiCd charger. Failure to
use the proper charger may cause a fire, which could result in personal injury/property damage.!
Never charge batteries unattended. When charging LiPo/Li-ion batteries, batteries should constantly be observed to
monitor the charging process to ensure batteries are being charged properly and to respond to potential problems
which may occur.!
Some LiPo/Li-ion chargers on the market may have technical deficiencies and charge the LiPo/Li-ion batteries
incorrectly or at an improper rate. It is your responsibility to ensure the charger you purchased works properly.!
If at any time a battery begins to heat, smoke, swell, or balloon, immediately stop charging the battery and disconnect
the charger, then observe the battery in a safe place for approximately 15 minutes, since the battery could leak and
react with air, causing chemicals to ignite and result in a fire. Since delayed chemical reaction can occur, it is best to
observe the battery as a safety precaution, in a safe area outside of any building or vehicle and away from any
combustible material.

HHR-4X56B Dual-lane Kits - Lane Functions
Using Lanes:
•The IN and OUT Lane Selection Buttons on the HHR-8056B readers are used to select the desired IN (ingress) or
OUT (egress) door, gate, or lane.!
•When lit, the LEDs above the Lane Selection Buttons indicate which lane the Handheld Reader is operating in. The
Handheld Reader will always be in either the IN or OUT lane. !
•The IN and OUT lanes have different Wiegand outputs on the Base Unit, this allows the Handheld Reader to
appear as two separate readers to the access control panel. The IN Lane’s Wiegand output is on Board A, and the
OUT Lane’s Wiegand output is on Board B.
Lane Conflicts:
•A Lane Conflict is caused by multiple Handheld Readers operating in the IN or OUT lane at the same time. !
•When the Handheld Reader detects a Lane Conflict, the Lane LED above the IN or OUT Lane Selection Button
(whichever Lane the conflict is in) will be flashing. !
•During a Lane Conflict all affected Handheld Readers will still read credentials, however, no data will be sent to the
Base Unit. !
•Lane Conflicts can be resolved by ensuring that only one Handheld Reader is set to the IN or OUT Lane.

HHR-4X56B Dual-lane Kits - Using the Vend Button
The Vend Button on the Reader is used to operate Relay 3 on Board A while the Reader is set to the IN Lane and Relay
3 on Board B while the Reader is set to the OUT Lane. Common applications for the Vend Button are allowing the
Reader operator to manually open a gate or trigger a duress alarm. !
Relay 3 on both Board A and Board B is a dry contact output by default. Power can be run through this relay if
required, however, this relay rated for a max of 30 VDC at 1 amp. More detailed relay specifications can be found in the
Specifications table on pg. 2. !
Below are diagrams that show how Relay 3 changes state when the Vend button is pressed.
The diagram to the right
shows the Reader set to the
IN Lane. The Vend button is
not being pressed and the
state of Relay 3 on Board A
is normal (continuity
between Relay 3 Com and
Relay 3 N.C.).
In this diagram, the Reader
is set to the IN Lane and the
Vend button is being
pressed. The state of Relay
3 on Board A is active
(continuity between Relay 3
Com and Relay 3 N.O.).

HHR-4X56B Dual-lane Kits - Bench Testing Steps
Bench Testing Steps
The HHR-4256B and HHR-4356B kits have multiple readers, go through steps 1-8 for each reader. !
1. Power on the reader. Press the IN lane selection button to set the reader to the IN lane. The blue LED will be on and
solid when the reader is powered on. The blue LED will changed to flashing when the reader is communicating with
the Base Unit. !
2. Present a valid credential to the reader. The red and green LEDs will flash once, indicating the credential has been
read. Verify that the access controller has received the read on the Wiegand port Board A is connected to. Observe
the Access Granted Response; the green LED will be flashing, the reader will vibrate, and the reader will emit a high
pitched tone. The Access Granted Response will last as long as the LED In pin on Board A is activated. !
3. Present an invalid credential to the reader. The red and green LEDs will flash once, indicating the credential has
been read. Verify that the access controller has received the read on the Wiegand port Board A is connected to.
Observe the Access Denied Response; the red LED will be flashing, the reader will vibrate in a pulsing pattern, and
the reader will emit a low pitched tone. The Access Denied Response will last as long as the Relay 1 In pin on Board
A is activated. !
4. Press and release the Vend button. Verify that Relay 3 on Board A has changed state. Observe that the duress
alarm activates, the door/gate opens, etc. A volt meter in continuity mode can also be used determine the state of
the relay. When the Vend Button is pressed, there will be continuity between Relay 3 COM and Relay 3 N.O. for as
long as the Vend Button is held down.!
5. Press the OUT lane selection button to set the reader to the OUT lane. The blue LED should still be flashing,
indicating the reader is communicating with the Base Unit.!
6. Present a valid credential to the reader. The red and green LEDs will flash once, indicating the credential has been
read. Verify that the access controller has received the read on the Wiegand port Board B is connected to. Observe
the Access Granted Response; the green LED will be flashing, the reader will vibrate, and the reader will emit a high
pitched tone. The Access Granted Response will last as long as the LED In pin on Board B is activated.!
7. Present an invalid credential to the reader. The red and green LEDs will flash once, indicating the credential has
been read. Verify that the access controller has received the read on the Wiegand port Board B is connected to.
Observe the Access Denied Response; the red LED will be flashing, the reader will vibrate in a pulsing pattern, and
the reader will emit a low pitched tone. The Access Denied Response will last as long as the Relay 1 In pin on Board
B is activated.!
8. Press and release the Vend button. Verify that Relay 3 on the Board B has changed state. Observe that the duress
alarm activates, the door, gate, or other equipment. A volt meter in continuity mode can also be used determine the
state of the relay. When the Vend Button is pressed, there will be continuity between Relay 3 COM and Relay 3 N.O.
for as long as the Vend Button is held down.!
9. Once the HHR Base Unit and Reader(s) have passed these bench testing steps, the components are ready to be
installed in the field.

7/64” Drill Bit (if not using wall anchors)
HHR-4X56B Dual-lane Kits - Field Installation
A. Determine Base Unit Location
1. The Base Unit should be mounted in a location which allows for the maximum range between the Base Unit and the
Handheld Reader. Typical maximum range for the wireless connection between the Handheld Reader and the Base
Unit is 150 ft. (45 m) line-of-sight indoors, or 500 ft. (152 m) line-of-sight outdoors.
2. It is not recommended to locate the Base Unit directly above the area where the Handheld Readers will be used, as
this may cause communication problems. !
3. The Base Unit location must accommodate a wired connection to the access controller (see Section C). !
B. Mounting the Base Unit
1. It is recommended to temporarily set up the Base Unit at its desired mounting location to test communication with
the Handheld Reader before permanently mounting the Base Unit. Use a battery to power the Base Unit and test
the wireless connection between Base Unit and the Handheld Reader in the desired operating area. !
2. The Base Unit should be mounted at least 10 feet (3 m) above the ground outdoors, or 6-8 feet (1.8 - 2.4 m) above
the floor indoors. If obstacles are present (such as vehicles, trains, building, trees, etc.) choose a location high
enough, or with good line-of-sight to avoid interference from these obstacles. !
3. A non-metal mounting surface is recommended for the Base Unit, as metal surfaces reduce the effective range
between the Base Unit and the Handheld Reader. If mounting the Base Unit on a metal surface is unavoidable, use
a non-metal spacer to space the Base Unit at least 2 inches (5 cm) from the metal surface. !
4. The Base Unit must be mounted in the upright position. When correctly oriented, the “Cypress” sticker can be
clearly read and the enclosure door will open to the left. !
5. Remove the plastic backplate and circuit boards from the enclosure before drilling any holes in the enclosure to
avoid damaging the backplate or circuit boards. The backplate is held in place by 4 Phillips screws at each corner
of the enclosure.

6. Install a grommet on the bottom of the enclosure using the preformed divot as a guide for the drill bit (see diagram,
below).
7. Drill the mounting holes into the mounting surface.!
a. If using wall anchors: following the hole pattern in the diagram above, use an appropriate 3/16-inch drill bit to
drill holes into the surface with a depth of at least 1.25 inches. Place the wall anchors into the newly drilled
holes.!
b. If not using wall anchors: following the hole pattern in the diagram above, use an appropriate 7/64-inch drill bit
to drill holes into the surface with a depth of at least 1.25 inches.!
8. Use a Phillips screwdriver to mount the enclosure to the surface using the four #8 x 1 inch screws included with the
enclosure (see diagram, pg. 21). !
9. Use a Phillips screwdriver to mount the backplate and circuit boards in the enclosure. !
10. Enclosure locking screws (6-32 x 3/8) max torque rating 8.5 inch-pounds.
