Stanley AC571 Guia De Instalacion página 4

Introduction
Both the AC571 and AC572 desktop readers use DualTech technology to allow tokens and cards to be read
by a PC running Stanley administration software.
The AC572 comes with a non-isolated RS-485 interface and line driver for connection to a AC512 access
controller. The line driver is plugged in to the RS-232 port of the AC512. Other AC512s can be connected to
the first AC512 via RS-485 terminals to provide a direct channel (see Page 3). For applications that require
an isolated RS-485 interface, the AC572 can be wired into an isolated RS-485 hub.
Notes
The +5V output is derived from the USB's power line and is provided for reference. No more than 50mA
should be drawn from this or the USB's power limit will come into operation and the computer will shut
down the USB port. This may require a reboot of the PC before the reader will operate again.

2. Plug the desktop reader in to a spare USB port and the Found New Hardware Wizard window is
