The AMC2 (Access Modular Controller) is used as an
access controller in the access control systems ACE
(ACCESS ENGINE) from version 2.0 onward, Access
Personal Edition, and Access Professional Edition. The
device controls a group of one to eight access points.
These access points, also known as entrances, mainly
consist of doors, gates, barriers, turn stiles, revolving
doors, mantraps, ID card readers, door opening
elements and sensors. The AMC2 can control up to
eight ID card readers (depending on the reader type)
and is designed for fully processing the access logic at
the assigned entrances.
Status checks can be carried out using the eight
analog inputs. The eight relay outputs are used to
activate the door opening elements and/or generate
the security activation and signaling. The AMC2 stores
all necessary information in a battery-buffered memory
and a compact flash storage element so that, even
when the unit is offline, it is able to carry out
independent authorization checks on access points,
take access decisions, control closing/opening
elements and register movement events.

1 = Host computer
2 = AMC2
3 = Card reader
4 = Communication and power supply
As shown in the diagram, the AMC2 is integrated
between the host system (e.g. Access Engine) and the
peripheral devices.
They are connected to the host system via RS485,
RS232 (e.g. modem operation) or Ethernet, depending
on the size of the system. The relevant host interface
is selected during installation. All three interfaces are

available on the device by default. With RS485
operation, a maximum of eight AMC2’s can be
connected to one party line.
There are up to four slots on the peripheral bus for
readers, including the slot for the power supply.

Host connections
RS232 host interfaces
The Access Engine application administers up to 32
serial direct connections (ports), theoretically allowing
32 AMC2’s to be directly connected in series.
Notice
Since PCs only have a maximum of two COM
interfaces by default, the following connection
variants are preferable for configurations with
more than two AMC2’s:

Installation/configuration notes
Power supply
An external power supply (10 to 30 V DC) for the
AMC2 is connected to the first (positive) and third pin
(negative).
When using an uninterruptible power supply (UPS),
the relevant UPS output relay is connected to the pins
• 4 and 7 for alternating current
• 5 and 7 for the battery
• 6 and 7 for direct current
Otherwise, these pins will short-circuit.

3 = AMC2
4a = RS232 connection
4b = RS485 connection: Up to eight AMC2’s can be
connected to one RS485 interface for each AMC-MUX.
The AMC-MUX interface converter should be used if
more than two AMC2’s are connected.
The interface converter generates an RS485 bus (2 or
4-wire) from a COM port and thus allows up to eight
AMC2’s to be connected with the RS485-typical
distances (1200 m/3900 ft.).

Alternatively, the RS485 host interface (2 or 4-wire)
can be activated in the AMC2 via a jumper. There are
two sets of connection points; one for the incoming
and one for the outgoing bus system.
Quantity restrictions
• Please follow the Access Engine installation and
configuration instructions regarding the maximum
number of access controllers on one access control
system and the number of cardholders.
• Max. 4 access points/entrances
• Max. 4 ID card readers
• Max. 3 peripheral devices via internal RS485 bus
• Max. 200,000 cardholders
ID card reader connections
Wiegand interfaces
The AMC2 4W has four connections for connecting up
to four ID card readers.
ID card reader and door control element interfaces are
split into four channels, each with four connection
plugs.
The following definitions apply to the Wiegand
interface:
• 10-wire interface (incl. shield)
• Maximum cable length of 158 m (500 ft.) to ID card
reader
• 26-bit Wiegand format
• 37-bit Wiegand format
Default configuration of the Wiegand interface on the
ID card reader:
112V+ reader power supply
212V- reader power supply

Reader and door models
The AMC2 controls the connected reader via
predefined door models.
Door models govern in accordance with the relevant
security requirements
• Number and usage of the readers connected to the
AMC2, e.g. input and output readers, input readers
and buttons etc.
• Number and application type of the AMC inputs, e.g.
door status, output button, revolving door position,
GMA etc.
• Number and usage of AMC outputs, e.g. door opener,
mantrap contact, signal light switching etc.
The maximum number of entrances to be managed by
one AMC2 is ultimately defined by the door models
used and their requirements regarding readers and
inputs/outputs.

RS485 interfaces
The AMC2 4R4 has four connections for connecting up
to eight ID card readers. The interfaces are divided to
two busses – all possible readers (up to eight) can be
connected to one interface.
RS485 interface definition:
• 2-wire interface: Using the 10-pin pluggable
connector.
• Max. length of the bus: 1200 m
• Transfer rates: 9,6 or 19,2 kBit/s
Default configuration of the Rs485 interface on the ID
card reader:
Notice
Therefore, when planning an access system, you
must first assign the relevant door models to all
entrances that are to be controlled. Only then can
you configure the AMC reader.
Voltage equalization - grounding
• Different voltages can be equalized using jumpers
with protective ground.
• A line (shield, equipotential bonding line) with
protective ground can only be connected in one
position.
• For further instructions, please see the operating
manual!
Contacts
Inputs
The eight analog inputs can be used as digital or
analog contacts. For analog use, resistance values can
be specified that make it possible to carry out a
further check for cable breaks and short-circuits.
Relay outputs
The relay outputs offer the following functions:
• The outputs can operate with potential free contacts
for external power supply (dry mode).
Page 4
4 | AMC2 - Access Modular Controller
• The outputs can operate using the internal voltage of
power supply (wet mode).
• Only ohm resistive loads can be connected to the
relay.
• Inductive loads must be bypassed via recovery
diodes. These diodes (1N4004) are enclosed.
General instructions
• AMC2 and related equipment should be mounted in a
"secured area".
• Detailed connection conditions are specified in the
operating manual!
• After purchase, primary AC power must be carried
out by a licensed electrician.
