to 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 &

your body.

RF Exposure: A distance of 20 cm shall be maintained between the antenna and users, and the

transmitter module may not be co-located with any other transmitter or antenna.

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 Series controller comes with built in bootloader program. Built in bootloader program will enable user to upgrade firmware without sending back to factory. EasyIO FC20 do not have an Ethernet port. It only has RS 485 serial port. Firmware Upgrade is perform via direct serial connection to the controller.


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.

Daisy Chain Network Topology

RS485 Connection


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.

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


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 Connection


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.

**We DO NOT recommend you to drive a relay directly from UO 0-10V mode as it is not design for it

and will damaged the AO. **

For voltage mode, the circuit able to drive load with a minimum impendence of 8,000 ohms. 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 perform a hardware reset when the Reset Button is toggle. 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.

Button and LED indications

LED Conditions Description

1 PWR PWR is used to indicate the presence of

24VAC power source, and internal power

2 ERR ERR is to indicate whenever there is

communication errors.

3

STS

STS is used to indicate the heartbeat of the

Microcontroller. The STS LED will blink at

1-second interval in normal operation

condition.

4 TXRX TXRX is used to indicate when there are

communication activities (Transmitting or

Receiving) on the communication port.
