apC/8X Basics
The apC/8X controller is housed in a 16 AWG metal wall-mounted cabinet, 
which has tamper switches on the front and rear and can be used in a variety 
of configurations. 
The standard apC/8X panel has eight inputs, eight outputs, and one RS-485 
reader port that can support a maximum of eight readers.
In the basic apC/8X installation, the eight card readers are wired in a daisy 
chain configuration. Installing a Star Coupler or Mini Star Coupler enables 
you to wire the apC/8X’s eight card readers in a star configuration, daisy 
chain configuration, or a combination of configurations. 
Note: As many as 16 apC/8X units can be connected in a 
communications chain. However, for best results, the 
recommended maximum number of apC/8X units per chain is 
nine. On a network connection, the recommended maximum 
number of apC/8X units is six.
The static RAM of the panel consumes minimal power for storing memory 
and data. The panel is capable of serial RS-232 bus/daisy chain RS-485 or 
dual-line communications with an optional board. (Optional boards are 
described in “apC/8X Optional Modules,” on page 1-4.) 
The apC/8X panel is compatible with the Software House C•CURE 800/8000 
system.
Software-Controlled Options
The apC/8X device offers software-controlled features such as timed 
activation/deactivation commands, 32-bit card numbers, elevator access, 
dialup mode operation, and antipassback control. 
A single apC/8X device can use multiple card technologies, site codes, and 
facility codes. The apC/8X full-year real time calendar/clock allows 
activation and deactivation of cards on specified days.
