The connection can be made either by serial connection (using the Host Communication Connection) or by
Ethernet (using the RJ-45 jack of the ENI-100 Network Interface Module).
3.3.1 Serial
Using the Host Communication Connection (and an ASM-32 or ASM-48 driver), the connection from the
AAN-4 to the host can be made using RS-232 or RS-485 protocols. The choice to use RS-232 or RS-485
depends on many factors for the particular installation. The main differences are outlined below:
RS-232 RS-485
Maximum Distance 50 Feet (15 Meters) 4000 Feet (1200 Meters)
Devices Per Line
1 16 (AAN-4S is limited to
maximum 16 devices on one
serial line)
Communications Port Standard on Many PCs Requires Adapter (RS-232 to
RS-485) or Add-on PC Card
Data Rate
20K Bps 10M Bps
After choosing the method of communication, the proper wiring must be made from the host to the controller.
Typically, the communication will be from a standard 16550 UART COM-port on a PC which will be
connected directly to the AAN-4 in the case of RS-232 or through the use of an adapter or add-on PC card to
achieve the RS-485 signal. The communications wiring must cross-over from the PC to the panel as shown
in Figure 3.3.1.
The connection originating from the host PC will then be connected to the Host Communication Connection
(see table 2.1). Ensure that the proper communications driver is installed in J10 (ASM-48, part number
430-132, for RS-485, ASM-23, part number 430-131, for RS-232). When communication established, the
activity will be seen on the comm activity LED. The blinking rate of the LED will vary at first as
communication is established and configuration is updated, and then should blink at a steady rate of several
times per second.
