Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
•Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate this equipment.
FCC Caution
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator &

Introduction
EasyIO FW Series is the most powerful wireless Sedona controller in the market. It is equipped with two
32-bit Processors, the first in the Automation industry, with a 580MHz MTK processor and an ARM M0
Cortex for the I/O management and A-D processing, and also with a Linux 3.18 OS for premium
performance. Supports BACnet as server and TCom or premium performance with Niagara AX and N4.
The Build in boot loader can be carried out remotely. No more manual service button
needed is used. 
Firmware upgrading can be done remotely and without any assistant. 
Firmware upgrading is via ftp client. 
This document describe about basic connection and technical specifications.
It applies for EasyIO FW Series family.

Hardware Configurations
Power supply Connection
Both AC and DC can be used for EasyIO FW Series controller. Refer to electrical specification for the
working range. In order to avoid damage on the controller input/output devices and RS485 connection,
use individual power supply for each controller. If a single power supply is used to power up multiple
EasyIO FW series, make sure controller power supplies are connected with the same polarity.

RS485 Connection
RS485 connection must be terminated at both ends with termination resistor, typically 120 Ohms. It is
recommended to use shielded twisted pair wire (STP) for the wiring.
Lightning protection circuit is highly recommended to be installed at one end of the wiring. The controller
should be wired in daisy chain network topology as shown as image below. If wire branch can be avoided,
keep it as short as possible, and never connect more than one device to the wire branch (it is not
recommended).
Be careful if single power supply is used for all connected RS485 device, make sure all devices are
having the same ground connection. Make sure you are connecting the same wire for the same
terminal position, all “H” terminals connected to the same wire.
