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.

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.
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:
1 = Host computer
2 = RS232/485 AMC-MUX converter
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.).
