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

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.

RS 485 Serial port settings.
Every EasyIO FC controller comes with 2 RS -485 ports respectively D1 and D2.
Below is a table explaining the details for each serial port configurations.
Port Number
Protocol Communications supported
Default Serial port settings
Remarks
Port 1
( D1+ , D1- )
Modbus OR BACnet
Protocol selection is done via DIP switch 1.
DIP 1 = OFF = Modbus RTU
DIP 1 = ON = BACnet MSTP
Modbus
Baud Rate : 19.2K
Parity : even
Data Bit : 8 (Not editable)
Stop Bit : 1
BACnet
Baud Rate : 19.2K
Port 1 is used to perform;
-Firmware flashing. (FwTool.exe)
-Virtual Device for program downloads. (FcVirtualDevice.exe)
-Terminal mode for serial configurations editing. (FwTool.exe)
Port 2
( D2+ , D2- )
Only supports Modbus RTU Protocol
(Default).
It supports Modbus Master as well if
configure via FC Virtual Tool.
Modbus
Baud Rate : 19.2K
Parity : even
Data Bit : 8 (Not editable)
Stop Bit : 1
If port 2 is configured Modbus Master RTU (Default)
Port 2 is used to perform;
-Virtual Device for program downloads. (FcVirtualDevice.exe)

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.
