as it is not intended for such use or application.
AspectFT-Nexus & AspectFT-Facility Installation Guide (1/02/2014) 1-3
NOTE
This equipment has been tested and found to
comply with the limits for a Class A digital device,
persuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when the equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radion communications.
Operation of this equipment in a residential area is
likely to cause harmful interference in which case
the user will be required to correct the interference
at his own expense.

1.2 PRODUCT MOUNTING
This product ships with an approved enclosure consistent with most electrical standards and regulations.
The product is intended for indoor applications only and should be installed in a location that is dry, and
free from excessive dust, vibration, and electrical interference. Mount the product in a location that allows
clearance for ease of wiring and service. Use the two keyhole-style screw holes located on the back of the
enclosure for assistance with mounting.

1.2.1 ENCLOSURE COVER
The enclosure cover of the Nexus controller is designed to be removed for servicing the device. The cover
is removed by unscrewing the 4 hex head screws in the cover then sliding the cover vertically before
pulling it away from the base. Care should be taken when removing the cover on a mounted unit to prevent
it from being dropped and damaging the cover or harming the user.

1.3 HARDWARE LAYOUT
Below is an illustration of the hardware layout of the AspectFT-Nexus and AspectFT-Facility. The device
includes connection ports for main power, EIA-485 connectivity, and Ethernet connectivity.
Figure 1-3 Hardware Layout
1.3.1 UNUSED PORTS
The motherboard of AspectFT-Nexus and AspectFT-Facility controller contains 3 RS-232 serial ports,
3.5mm audio ports, and a DC support port. These ports contain no field functionality, but are reserved for
future functionality.
1.3.2 POWER REQUIREMENTS
This product requires a transformer capable of providing 24VAC power to the AspectFT-Nexus and
AspectFT-Facility. Use a UL listed Class 2, 24VAC transformer.
To connect power to the product, use the supplied two-position terminal plug. The output leads from the
transformer should be connected to the terminal plug. The terminal plug should then be connected into the
socket on the board. American Auto-Matrix recommends using 18AWG cable for power wiring.
WARNING
Do not share the power source for the
AspectFT-Nexus and AspectFT-Facility with
other devices. Damage to the product as a
result of improper power and wiring will void
product warranty.

1.4 COMMUNICATION CONNECTIONS
Communication connections made to device should be made with care. To avoid any possible conflict with
existing network communications, it is recommended that communication port and network configuration
of the device be performed prior to connecting the product to any associated field bus network.
1.4.1 ETHERNET NETWORK
Ethernet is a high-speed LAN widely used in commercial buildings. The main Ethernet network interface is
located on the motherboard of the product directly next to the serial RS-232 ports. A second Ethernet
connection, located next to the audio ports, is not active for use at this time.
The on-board Ethernet network interface supports 10Base-T (10Mbps), 100Base-T (100Mbps) and
1000Base-T(gigabit) Ethernet connections. The product will automatically switch to 100Base-T operations
if other devices and cabling connected to the same subnetwork support this.
1.4.1.1 CABLE TYPE AND LENGTH
Use an approved Category 5 (CAT5) Ethernet patch cable with RJ-45 plugs to connect the product to an
Ethernet switch or hub. Use professionally manufactured cables to assure transmission rates and
reliability between devices. Maximum length for Category 5 is typically limited to about 320 feet (100
meters).
