INTRODUCTION
The AM-CRI card reader interface is designed for use with Linear's
AE1000Plus, AE2000Plus, and AM3Plus access control systems. The
interface will support one or two 26-bit Weigand input devices.
If the readers used have a "hold" or "buffer" connection, two readers may
be used to the AM-CRI. If the readers do not have a "hold" or "buffer"
connection, one reader may be used with the AM-CRI.
Usually mounted near the readers, the AM-CRI interface connects to the
controller through a six-wire cable. Each reader connects to the AM-CRI
through a six-wire (one LED in reader) or seven wire (two LEDs in reader)
cable.
Two rotary switches in the AM-CRI select the PBUS device address for each
reader connected. Each remote PBUS device connected to the controller
must be set to a different device address. The address switches in the
AM-CRI must be set to different addresses if two readers are used.
Power is supplied to the interface and reader(s) from the controller. A power
selection jumper is provided for each reader. Five or eight volt power or
external power for locally powered readers can be selected.
