2.2.2 DIP Switch Function
Communications Address—This option sets the address that identifies the device on the
communications line. This setting must be specified in the host software in able to identify the device. A
maximum of 16 AAN-4 devices can be installed on one communication line (RS-485), with each having a
unique address (between 0-31). The communications address must also be specified in the host software
when the AAN-4 is connected though a network. NOTE: AAN-4 controllers can NOT be used on the
same serial communications line as an AAN-100 or AAN-32 controller.
Baud Rate—Specifies the baud rate for the serial line of interface. This setting must be the same for all
devices on the communication line connected to this port.
Input Monitor Mode—Specifies whether all inputs on the interface (Auxiliary inputs, door contacts, exit
push buttons) will be monitored by comparing the resistance value of the input line with the expected value.
ON—In the event of tampering with the input, the interface will report the specific type of error.
OFF—Inputs will operate in standard mode.

2.3 Connectors
The AAN-4 has several connectors for interfacing with removable components. Take care when installing
and removing components in order not to damage pins or sockets. Do not use force greater than gentle
pressure when installing any components. Refer to the figure for the exact location of these connectors. The
connectors are also labeled on the AAN-4 in white lettering on the circuit board.
