EasyIO FC20 User Reference v1.3
Introduction
The EasyIO FC series is aimed at affordable ‘canned’ solutions for standalone applications, such as Roof
Top Units, Fan Coils, AHU’s, package units etc.
EasyIO FC20 controller comes with built in bootloader program. Built in bootloader program will enable
user to upgrade firmware without sending back to factory.
EasyIO FC20 does not have a Ethernet port. It only has RS 485 serial port.
The only way for firmware upgrading is through serial.

Hardware Configurations
Power supply Connection
Both AC and DC can be used for EasyIO FC-20 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, make sure controller power
supplies are connected with the same polarity.
Power Supply Connection
Multiple controllers share single transformer connection
EasyIO FC20 User Reference v1.3
RS485 Connection
RS485 connection must be terminated at both ends with termination resistor, typically 120Ohms. It is
recommended to use shielded twisted pair wire (STP) for the wiring. Lightning protection circuit is
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.
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.

Jumpers Setting
Below image shows the jumper setting for Universal Input, Analog Output, BACnet/Modbus Selection,
and the BACnet MSTP ID (1~127) or Modbus Serial ID (1~127).
The controller comes with BACnet and Modbus protocols selection. By default, Modbus protocol is
selected. To switch to BACnet protocol, toggle the ‘1’ of the dip switch to ON.
The remaining DIP switch ‘2’ ~ ‘8’ are for BACnet MSTP ID or Modbus Serial ID (address 0 is not available;
it will be set to 1) depending on DIP switch 1 selection.
Any changes to the DIP switch, a power cycle is needed.
EasyIO FC-20 Jumpers Setting
Image below show the DIP switch settings details.
For serial addressing it uses binary bit. The Least Significant Bit (LSB) in DIP 8. The Most Significant Bit
(MSB) is DIP 2.
The white the spot/white square represent the DIP switch in ON position.

Digital Output Wiring Connection
EasyIO FC-20 has four general purpose isolated digital output connections (relay output). Each relay
output able to drive up to 1A 30VDC/ 48VAC load.
It does not output voltage or current. It is a dry relay contact.
Digital Output Connection
EasyIO FC20 User Reference v1.3
Universal Input Connection
EasyIO FC-20 has twelve non-isolated universal inputs. The universal input supports three type of analog
signal i.e. resistance, voltage and current transmitter via hardware jumper and internal register settings:
a) Resistance – The working range of resistance is 0 – 300K Ohms. If the input is configured as
Thermistor type, the system provides 8 customizable temperature lookup tables for resistance to
temperature translation. The commonly used Thermistor like 10K, 10K with Shunt, 1K Balco and 1K
Platinum are all supported
b) Voltage – Two selection of working range 0 – 5V and 0 – 10V. The minimum input impedance of
voltage input is 1 Mega Ohm.
c) Current – Two selection of working ranges 0 – 20mA and 4 – 20mA. The current input impedance is
less than 25 Ohm.
d) Pulse Input – Only UI1, UI2, UI3 and UI4 are capable of receiving high speed pulse. Minimum on time
pulse is 25ms and minimum off time is 25ms. Refer to image below.

Universal Input as Pulse Input specifications, Max 20Hz
Analog Output Connection
EasyIO FC-20 has four Analog Output connections. Each Analog Output can be configured to drive voltage
or current output via hardware jumper setting and internal register settings.
The working range for voltage is 0 – 10V and for current either 0 – 20mA or 4 – 20mA. For current
transmitter, the circuit able to drive load impedance up to 800 ohm which is ideal for long wire
connection (up to 500 meter wire length).
Analog Output Connection

Buttons and Indications
The controller will do a hardware reset when the Reset Button is pressed whenever manual restart is
required.
The Service button is used to activate the built-in bootloader program for software upgrade.
Each digital output has a correspondence LED to indicate its current state.

Software Configurations
In order to connect to the new EasyIO FC Series via the Virtual Machine, some files are needed. EasyIO FC
series is not a Sedona Controller but it uses the Sedona environment to program it.
Hence there will be no extra software needed.
These kits are hardware dependent. Only works for FC series.
The FC series comes with a User Interface to configure the Temp Table as well. It works only with Sedona
workbench or Embedded Sedona Workbench in Niagara Workbench.
Follow the below instructions before connecting to the controller via Sedona Workbench.
Install platform files and kits files
Step 1
Get the required files from EasyIO technical support at support@easyio.com. The files are the Sedona kits
and platform manifest for the EasyIO FC series.
Step 2
Close the workbench.
Locate the Sedona folder in the Niagara installation directory;
Niagara Version
Niagara Ax 3.5.xx
Niagara Ax 3.6.xx
Niagara Ax 3.7.xx
Sedona directory
Niagara\niagara 3.5.xx\sedona\
Niagara\niagara 3.6.xx\sedonaBundles\sedona
1.1.xx\sedona\
Niagara\niagara 3.7.xx\sedona\
Step 3
Copy and merge the 2 folders that obtain from EasyIO technical support.
The 2 folders are: platform and kits
For Niagara Ax 3.5 User go to step 4.
For Niagara Ax 3.6 User go to step 5.
For Niagara Ax 3.7User go to step 6.
Step 4
For Niagara Ax 3.5.xx user. Drag and drop it in to the Sedona root folder. Hit “Yes” on the pop up to
merge the files.
