Definitions of IO Modes
The C2N-IIF can operate in one of three modes. Following are
definitions of each mode.
Essex Mode
Essex mode configures the C2N-IIF for communication with five-button
keypads manufactured by Essex Electronics. In this mode five of the six
logic-level inputs are reserved for connection to an Essex keypad (shown
in the following diagram), leaving one logic-level input available for
reading other logic-level devices. All of the switched outputs are
available for connection to contact closure devices such as gates and
garage door openers. Essex mode also provides control of the panel's
backlight.
