The ezeio™ Controller comes ready to start monitoring,
logging and controlling over the Internet.
As soon as the controller is connected to power and an
Internet connection, it will start communicating with the
eze System servers. There is no need for special
software or network setup. The ezeio connection is
encrypted, bi-directional and very efficient.
Ordering Information.
ezeio-STD ezeio Controller with Ethernet port, 4 analogue inputs and Modbus-RTU RS-485 Comms.
ezeio-GSM ezeio Controller with GSM/3G transceiver, Ethernet port, 4 analogue inputs and Modbus-RTU
RS-485 Comms.
ezeio Controller Compatibility.
The Modbus-RTU RS-485 port on the ezeio controller can be used to connect to Intech Micro Stations: 2400-A16,
2400-M-R and 2100-A16. This allows the controller to be expanded to log up to 40 channels max per ezeio controller.
If additional relay outputs are required, the 2400-R2 can be connected to the 2400-A16 for relay expansion - refer to the
2400-A16 Installation Guide for more information.

Jumper setting Description
0~5Vdc.
Input impedance is >70kOhm.
Raw reading is about 10000 at 5.0V (0.5V per count).
0~10Vdc.
Input impedance is >70kOhm.
Raw reading is about 10000 at 10.0V (1mV per count).
0~30mA (suitable for 4~20mA transducers).
An internal 100 Ohm resistor connects the input terminal to Common.
Raw reading is about 10000 at 30mA (3uA per count).
Contact, Pulse or Resistive (0~50Ohm).
An Internal 10K resistor will hold the input to 5V.
This is the factory default setting.
To access the input jumper settings, open the ezeio™ by removing the four black screws.
Read the eze User Manual pages 13 through to and including page 16, covering input connections.
Getting started with configuration.
Go to www.ezecontrol.com
Click on the ‘Configure’ tab
And then the + by the Inputs:
Now select which input you wish to configure. Select the
‘Input type’ to match the configuration of the ‘Jumper’
setting in the table above. Always remember to select
‘Save Changes’ after making a change.
Important Note: The analogue inputs have a nominal
calibration only (ex factory), and where accuracy is
required, individual calibration of each channel is
required. This is done with the use of an accurate signal
calibrator.
Section 1 covers the ezeio Controller 4 local inputs, and Section 2 covers adding the power of the 2400-A16, to
expand the inputs up to 40, plus adding more outputs.
Section 1 - ezeio Controller.
Configuring the ezeio Controller local inputs.
The ezeio™ controller has four standard inputs. Each input may be configured individually in one of the four ways
described here:
4~20mA Resistance or
Pulse input

4. Now click on ‘Save changes’ and go back to the eze ‘Status’ tab.
3. Now click on ‘Linear analog’ and enter the values as shown next:
Point 1 and Point 2 are what we want this input to read, which in this example is
‘0~10Vdc’.
Point 1 is the zero point, which is 0 for the Raw Value and 0 for the Value.
Point 2 = 9798 which is the Raw Value from step 1 at 10Vdc input, and the ‘Value’
for this example we want to read 10.
If you wish this to actually read another value, for example 100% then enter 100.
Click on ‘Use’.
2. Now go to the eze Configure page and click on ‘Input type’ and select ‘Custom’ as shown.
Note: Do not use the percentage symbol in the
‘Input name’ and ‘Unit’ text boxes, as this will result in
an error.
Easy steps for Calibration.
1. As an example: on the ezeio Controller Input 2, the analogue input is set to 0~10Vdc. Apply an accurate 10Vdc
signal to this input and on the eze ‘Status Page’, note the ‘Raw’ reading on channel 2.
In this example below the Raw reading = 9798.
6
5. The Status screen now displays input 2 at exactly 10.00 (or whatever value you have entered).
6. If you require good accuracy at a particular point of the span, then calibrate at that point instead of the full span point.
7. For the best average accuracy calibrate the scale between 0~75% of span.
8. Apply this procedure (as applicable) to all other analogue inputs on the ezeio Controller inputs to achieve accurate
calibration.

Section 2 - 2400-A16.

The 2400-A16 is a high quality, high accuracy I/O station (input/output
expansion station), designed for a wide variety of applications.

Two Isolated, Relay Outputs for alarm or control.
Comms Ports (connecting to eze):
Port 1: Isolated RS485.
Port 2: Isolated RS485.
USB programming port via XU-USB programming key.
2400-A16 Notes:
1. More than one 2400-A16 can be added to a ezeio controller.
2. The
ezeio Controller will accept up to 40 inputs total per ezeio controller (this also includes the 4 analogue inputs
on the ezeio controller if they are used).
3. The 2400-A16 is available with 2 options for the number of analogue inputs: 8 inputs or 16 inputs.
Adding a 2400-A16 station to an ezeio Controller.
Follow these steps to add one or more 2400-A16’s:
Disconnect both the ezeio Controller and 2400-A16 from the power supply.
First is to connect the 2400-A16 to the ezeio Controller’s ‘ModBus 485’ port.
The 2400-A16’s comms ports 1 & 2 are both Modbus RTU RS485 capable.
Connection to the ezeio Controller ‘ModBus 485’ port is by using a standard Ethernet cable plugged into the ezeio
Controller and broken out to twisted pairs.
Two of these pairs are used to connect to one of the 2400-A16 RS485 ports, to the ‘ModBus 485’ port of the ezeio
Controller as follows:
Blue pair: Blue = 70 on 2400-A16 comms.
Blue/White = 71 on 2400-A16 comms.
Brown pair: Brown = 74 on 2400-A16.
Brown/White = not connected.

Getting started with configuration.
The first task is to configure the 2400-A16.
Connect the 2400-A16 to a computer as covered bottom of page 16 in the ‘2400-A16 Installation Guide’.
If you do not already have a copy of the ‘Intech Micro Station Programmer Software’, download and install from this link:
www.intech.co.nz/downloads/Install-StationProgrammer.html
Run the ‘Intech Micro Station Programmer Software’.
Click on the ‘Auto Detect 2400 Station’ button.
Configure the required input channel settings as shown.
The 2 important areas to make the same as the eze is the
Baud rate and the ‘Port Settings’.
This 2400-A16 configuration screen (left) displays the
parameters the 2400-A16 should be set to, with special
attention to the ‘Address’ which is referred to on the ezeio
Controller as the ‘Polling address’.
Note that on the 2400-A16, the ‘Address’ number can be set
differently for each (comms) port, so make sure the 2400-A16
port used for the ezeio Controller is the same as that used in
the ezeio Controller.
9
Remember that if two or more 2400-A16’s are connected
to the ezeio Controller, the 2400-A16 ‘Address’ and
corresponding eze ‘Polling address’ on the additional
unit(s) must be set to a different number.
Never use the same number twice.
For example, the 2nd 2400-A16 ‘Address’ and eze
corresponding ‘Polling address’ may be set to 2.
Enter your Account number, Login and Password.
The first task is to add the 2400-A16 onto the ezeio Controller. Click on the ‘Configure’ tab and wait for the Configure
screen to appear:
Click on ‘Devices’ and then click on ‘Add device’.
Select ‘Intech A16’ in the drop down list.
Next, enter the ‘Serial/ModBus address’, which must be set the same in
the 2400-A16 as well. In this example, 1has been entered:
Click on ‘Add device’.
Configuring the ezeio Controller.
Go to www.ezecontrol.com
10
Next, click on ‘System’.
Set the ‘Modbus speed’ (i.e. Baud rate) to the same as
that of the 2400-A16 (as shown). It is recommended to
also tick the ‘Use slow polling’ box.
Note: Not all the options are shown.
Next task is to add the 2400-A16 inputs onto the ezeio Controller:
Click on ‘Inputs’ and then click on ‘Add input’.
Example 1: eze temperature input scaling for RTD’s and thermocouples.
Select ‘Custom’ for all 2400-A16 input configurations.
Type in these 2 calibration details for all listed temperature probes, both RTD
and Thermocouple.
The 2400-A16 sends the exact temperature to the ezeio Controller.
Chose a ‘Logging’ time.
Note: Failure to select a Logging time will result in this input not being
viewable on eze.
In this case, the Ambient Temperature Probe is wired in the 2400-A16, input 1.
Important! eze System inputs cannot be re-ordered, so the initial setup is critical!
