AMC2 4W-EXT - Wiegand Extension Board
The extension module AMC2 4W-EXT is equipped with four
Wiegand type reader-interfaces plus eight inputs and eight
outputs. Hence with the AMC2 4W-EXT it is possible to
double the number of readers on an AMC2 4W from 4 to 8.
The AMC2 4W-EXT can not be deployed as an independent
controller but only as an extension module for the AMC2
4W. Control and access decisions and bookings are carried
out by the AMC2 4W alone.
The AMC2 4W can be extended by a maximum of one
AMC2 4W-EXT plus a maximum of three I/O extension
modules. The I/O extension modules AMC2 8I-8O-EXT,
AMC2 16I-16O-EXT, or AMC2 16I-EXT (in any combination)
are, like the AMC2 4W-EXT, connected via the AMC2 4W's
extension interface (RS485). As the extension modules
contain neither memory nor display they are controlled and
monitored entirely by the AMC2 4W.
Systems with Access Personal Edition
Software can only connect one I/O-Extension
to an AMC2 Controller.
The signal settings and parametrization of the readers
connected to the extension module, are carried out by the
configuration applications in the access control systems
Access Personal Edition and BIS Access Engine, and by the
AMC2 4W to which it belongs.
▶ RS485 connection to the AMC2 4W controller
