System
Description
The Aperio
Programming
Application
When a user presents a supported credential to the lock the Aperio system is designed to send the
credential wirelessly to the Communication Hub. The Communication Hub (wired through RS-485 or
Wiegand) then communicates with an EAC (Electronic Access Control) system. The EAC system provides
the access decision to the Communication Hub ehere access to the lock is either granted or denied.
Note: It is
recommended to
always verify the
radio link quality. To
do so see WFMN4A
Aperio Programming
Application
Instructions for more
information.
For a stable and reliable radio link it is recommended that the distance between the lock and the
Communication Hub is limited to 15 feet (5m). However, under good conditions (free air between the
units and limited radio interference from other transmitters) it is sometimes possible to increase the
distance to 35-45 feet (10-15m). Under poor conditions (heavy radio interface, etc.) it may be necessary
to keep the distance between the lock and the Communication Hub well below 15 feet (5m). There is no
minimum distance. If suitable, several Communication Hubs can be positioned together as long as the
Hub-to-Hub distance is 1 foot (.2m) or more.
Figure 2. Placement of Communication Hub
Typically, the LED on the Communication Hub cover should “point” to the lock.
The Communication Hub should be placed on the non-secure (key or card) side of the door.
Shorter distance and “light” materials in the walls permits placement on opposite sides.
Be aware of that metallic sheet or mesh will attenuate the radio signal. Inner ceiling is, for
example, sometimes covered with foil or metallic mesh.
Mirrors and larger metallic objects (like cable ladders) should kept at least 1 foot (2m) away
from lock or Communication Hub.
WiFi / WLAN routers and other radio transmitters operating in the 2.4 GHz band should be kept
at least 11-12 feet (3-5m) from the Communication Hub and lock.
Other possible sources of interference include microwave ovens, electric motors and other
high power electrical equipment. Keep at least 8-10 feet (2.5m) distance between the
Communication Hub and lock.
DIP switches 1-9 in the “OFF” position on the Communication Hub yield a default Wiegand configuration
that is compatible with most EAC systems. But better performance and increased functionality can result
from a customized configuration.
DIP 1: Controls use of RED LED signal to deduce Access Space Decisions.
ON: RED LED signal input is used.
OFF: RED LED signal input is ignored.
If a signal is available that asserts access denied decision from EAC. ENABLE DIP 1 “ON” and attach
signal to J100, RED.
If EAC system does not have RED LED output, only GREEN or does not use LED outputs to assert access
decisions, DIP 1 should be disabled “OFF”. Use lock relay output or similar EAC output (J100 GREEN)
instead.
Local override cards should not be used in conjunction with DIP 1 disabled (“OFF”) as this
configuration may produce an access denied based on a time out.
DIP 2: Reserved for future use.
DIP 3: Controls addition of parity bits if required:
ON: Addition of parity bits ENABLED.
OFF: Addition of parity is DISABLED transmitted as received.
When enabled, addition of one even parity bit (before) and one odd parity bit (after) is applied to the
actual credential.
Typically parity bits are already included in the creditial. In this case when DIP 3 is disabled (“OFF”)
transmitted credential may include parity.
DIP 4: Controls byte orders of transmitted credentials.
ON: The byte order is reversed compared to what is received as input to the Hub Wiegand EAC
interface component.
OFF: The byte order is left as is.
This setting is ignored as input to the hub in the case of the credential length does not make
complete bytes
The byte order received as input to the hub in the case of a 32 bit MIFARE UID credential is UID[3], UID[2],
UID[1], UID[0]. This means that the byte order is already reversed earlier in the chain compared to the
order specified in RFID interface standard ISO 14443-3.
DIP 5: Used for “Pairing Mode”.
ON: Pairing mode active.
OFF: Normal use.
When enabled/active the next time an unpaired lock attempts to pair, it will be paired with the hub.
For unpairing the APA tool must be used. Reboot the hub for changes to take effect.
DIP 6-9: Unused in AH-20
DIP 10: Controls use of external antenna if required.
ON: Selects use of internal antenna.
OFF: Selects use of external antenna.

The tamper switch will be activated if AH20 is removed from its bottom cover or plastic
adapter plate. If mounting to other than the plastic adapter plate as shown in the adapter
plate installation instructions it is necessary to align the tamper switch with a special tamper
tower post. See instructions provided with the optional mounting box.
AH13/AH30
Integration
(RS485)
The AH13/AH30 Communication Hub communicates with the EAC System through RS485. To
connect follow the below steps:
1. Set configuration options on DIP switch (S101).
2. Connect the RS485 signals to the EAC System (J100).
3. Connect to the supply voltage by wiring the 8 to 24 V (positive voltage) and GND
(ground) terminal.
Note
:
The Communication Hub must be powered with a voltage between 8 VDC and 24 VDC.
If communication is established, the LED will have a steady green light.

Select EAC
Address
The EAC address of the Communication Hub can be set in two ways:
By configuration from the Aperio Programming Application.
By use of the DIP switch (See Dip1-Dip4 on Page 9).
Selecting the RS-485 address from DIP switch through the Aperio Programming Application tool: the
APA tool maybe used to remotely set or override the physical dip switch address setting. When the
Communication Hub is set with the APA tool the physical dip switch settings are ignored. If new
firmware is loaded into the commmunication hub the address must be reset by using the APA tool or the
Communication Hub defaults go back to the dip switch settings.
The RS-485 bus consists of a twisted-pair cable with a characteristic impedance of between 90 Ohm
and 120 Ohms. Maximum bus length is1000m. Depending on the EAC system, a maximum of 16 units,
including the EAC system, can be connected to the same bus.
If there is more than one Communication Hub to connect, the hubs should be connected in a daisy
chain, not as a star so that all RS485 A connectors are connected together and all RS485 B connectors
are connected together on the RS-485 bus (Fig. 5). Both ends of the RS-485 bus must be terminated.
To terminate a Communication Hub at the end of the bus, switch 8 of the DIP switch must be in the ON
position. All other Communication Hubs in the chain must have switch 8 of the DIP switch set to the OFF
position. Refer to the EAC documentation for proper termination of the bus on the EAC side.
Pull up and pull down-resistors should be enabled once bus. Refer to EAC documentation for use of
pull up or pull down on the EAC side. If pull up and pull down from the EAC system is not used, one
Communication Hub on the bus should have DIP switches 6 and 7 set to the ON position.
Two examples of connection of multiple Communication Hubs to a single RS-485 bus of an EAC system:
The Communication Hub has a single LED that supports an optical scheme with red, green and yellow.
