INTRODUCTION
The AM-CRI card reader interface is designed for use with
Linear’s Model AM/II access control system. 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 AM/II control unit 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 device address
for each reader connected. Each remote device connected to
the AM/II 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 AM/II.
A power selection jumper is provided for each reader. Five or
eight volt power or external power for locally powered readers
can be selected.
