3.4 System Overview
The Access Controller AMC2 4W is connected between the
management host system and different peripheral devices. By
default a management host system is connected via Ethernet. A
management host connection via RS-485 or RS-232 is also pos-
sible.
Fig. 3.6 System overview
The number of controllers in one system is limited to 200.
Corresponding to the available interfaces one AMC can be con-
nected to each COM-Port using RS-232 mode. In RS-485 mode
up to eight access controllers can be combined on one party
line.
Via Wiegand interfaces up to four peripheral devices can be
connected to each AMC2 4W. The interfaces are point-to-point
connections - this means that only one reader can be connected
to one interface.
