Discrete Input/Output (DIO)
The Omega Link SP-003/SP-004 features 2 configurable discrete I/O pins. These can be used for a myriad of
applications including driving relays, physical alarms, or sensing dry contacts like door switches. The user
may configure the polarity of the inputs (active HIGH or active LOW) or Disable the DIO to utilize the
outputs (ON/OFF, PWM, SERVO).
The Discrete I/O input shares the output circuitry. The internal process drives the output control signal to
turn on the output driver which will force the output low. When the state of the DIO input signal is to be
read the processor applies 3.3 VDC to the Input Bias signal and reads the level detected at the Input Sense. If
the output is inactive an external signal may be used to force the input level low. A diode protects external
positive voltages, allowing the output driver to activate loads greater than the internal 3.3 VDC.
Figure 14: SYNC interface discrete I/O input configuration
Figure 15: Digital/Discrete I/O circuitry

14 | M 5 7 4 8
Setting DIO as an Input
To use a DIO pin as an input, make sure it is set to Active Low (default) in the Output Tab in SYNC.
Then, in the Input Tab, select a Type from the drop-down which includes DIO. Each DIO pin has an
internal pull-up, but to save power, the internal pull-up is only active when the unit takes a reading.
Advanced Scaling Options
The Omega Link SP-003/SP-004 allows for advanced scaling options on process and pulse inputs only. The
Advanced Scaling checkbox can be selected to expand additional configuration options. A gain and/or
offset can be applied to the input reading and the displayed unit can be changed.
To apply a gain or offset to the input, expand the Scaling menu and ensure that Apply Scaling is checked.
There, the gain and offset values can be adjusted. Both positive and negative values may be entered as well
as decimal numbers. The equation for the scaled input value is given below.
𝑰𝒏𝒑𝒖𝒕𝑺𝒄𝒂𝒍𝒆𝒅 =(𝑰𝒏𝒑𝒖𝒕𝑹𝒂𝒘 × 𝑮𝒂𝒊𝒏)+𝑶𝒇𝒇𝒔𝒆𝒕
The displayed units can be changed by entering a new value in the Unit field and clicking Apply Settings.
This field is limited to a maximum of 4 characters. Note that changing the Unit field does not change the
base unit type, only the display name. The Lock checkbox must be selected to use the user-defined Unit
field. Unchecking the Lock checkbox and clicking Apply Settings will revert the unit display back to the
default setting.

5.4 Output Configuration
The SP-003/SP-004 offers two discrete outputs that share circuitry with the discrete inputs. If an output is to be used
then the corresponding input pin must be set to Disable. See section 5.3.1 Discrete Input/Output (DIO) for more
information.
There are three types of output options –On/Off, Pulse-Width Modulation (PWM), or Servo. See section 5.4.1 for
more information on each type.
Outputs may be configured as either Active High or Active Low. When configured as Active High the output
conducts normally and becomes high impedance when activated. When configured as Active Low the Open-Drain
output is high impedance normally and will conduct when activated.
An output may be controlled in one of three ways –a scaled mapping to an input, an on/off control from an input
setpoint, or as an input alarm. Sections 5.4.2 through 5.4.4 describe these output control methods.

Device Output Range/Types
There are three types of output options –On/Off, Pulse-Width Modulation (PWM), or Servo. This section
describes these output options.
ON/OFF Output Type
The ON/OFF output mode switches the output to be a binary ON or OFF. Depending on if the
output is configured as Active Low or Active High, the ON/OFF mode can correspond to different
polarities.
Pulse-Width Modulation (PWM) Output Type
Pulse-Width Modulation (PWM) controls the amount of power given to a device by cycling the
on/off phases of a digital signal. PWM consists of a duty cycle and frequency. The Duty Cycle
measures the amount of time a signal is in the ON state as a percentage. The frequency controls
how fast the PWM cycle is repeated. Users can select between the following settings:
Option
Value
Description
Rate
100 Hz
Signal has a constant 100 Hz frequency with 0-100% Duty Cycle
10 Hz
Signal has a constant 10 Hz frequency with 0-100% Duty Cycle
1 Hz
Signal has a constant 1 Hz frequency with 0-100% Duty Cycle
0.1 Hz
Signal has a constant 0.1 Hz frequency with a 0-100% Duty Cycle
Signal Type
Active LOW
When the output is active, it is pulled to ground (LOW)
Active HIGH
When the output is active, it is in a high impedance state
SERVO Output Type
The SERVO output allows driving servo motors that control position. A Servo output is a special case
of the PWM output, where the ON time varies between 1.0 msec and 2.0 msec or between 0.5
msec and 2.5 msec, with the lower bound representing 0 degrees and the upper bound
representing 180 degrees of angular travel. The typical non-critical frequency is 50 or 100 Hz. Servo
outputs are always active high.

Figure 20: PWM function diagram

17 | M 5 7 4 8
Example: For the percent of angular travel, if the pulse width range is set to a range of 1.0-2.0 msec, then
selecting 50% of angular travel represents 1.5 msec or 90 degrees of travel.
ON/OFF Control Module
To configure an ON/OFF control module on a device, first ensure that the desired output pin is not
associated with any input alarms and that it is set as No Mapping in the Output Mapping menu in the
Outputs tab. The ON/OFF control module can be used with any selected output type including ON/OFF,
PWM, and SERVO. When enabled in PWM mode, ON corresponds to 100% duty cycle. When enabled in
SERVO mode, ON corresponds to 100% angular travel.
In the Outputs Tab in SYNC click on the icon located to the right of the available outputs. Clicking
the icon will open the Define ON/OFF Control dialog box as seen below.
The Enable Control checkbox enables the ON/OFF control module. If this box is unchecked, the output will
be disabled but the module with all its settings will remain available to be enabled at a later time.
The Inputs dropdown lists the available input sources and will depend on how the device is configured in
the Inputs tab.
The Setpoint field sets the threshold for activating the ON/OFF control module. The unit of the Setpoint
field will be the same as the unit of the chosen Input.
The Control Actions dropdown has options for direct or reverse control. In direct mode, once the Setpoint
value is reached then the output will be set to ON. In reverse mode, once the Setpoint value is reached then
the output will be set to OFF.

1.0 msec = 0°
1.5 msec = 90°
2.0 msec = 180°

18 | M 5 7 4 8
The DeadBand field together with the direct or reverse control action configures a deadband range around the
Setpoint where the ON/OFF control does not toggle. The unit of the DeadBand field will be the same as the unit
of the chosen Input.
•Example 1: the setpoint is configured for a 50 Hz rate input with a deadband of 10 Hz with direct
control action. The output will activate if the input rises above 60 Hz. Conversely, the output will
become inactive if the input falls below 50 Hz.
•Example 2: the setpoint is configured for a 50 Hz rate input with a deadband of 10 Hz with reverse
control action. The output will activate if the input falls below 40 Hz. Conversely, the output will
become inactive if the input rises above 50 Hz.
The Save button saves and applies the configurations settings to the ON/OFF control module. The Delete
button only appears for a previously saved ON/OFF control module and it removes the module and allows other
output types to be configured such as an alarm or mapping.
Setting an Alarm
Alarms are set by clicking the icon in SYNC on the desired input signal found in the Input Tab.
Configure the Condition that triggers the alarm by selecting an option from the drop down such as Above or
Below. The Threshold field(s) will change to display whatever is appropriate for the option chosen such as a
High Threshold for an Above condition or a Low Threshold for a Below condition. A Duration can be set for
the trigger as well where the condition must be met for a certain amount of time before the alarm flags.
Under the Action menu, the option to transmit or not transmit a notification can be set. The option to
enable an output can also be set. The output chosen must not be currently used in a sensor mapping or
ON/OFF control module. The data transmission interval may also be changed upon triggering an alarm, e.g.
increase the rate of transmission if an excessive value is detected. The Recovery menu allows the option to
clear the alarm after a certain Duration once the trigger condition is no longer met. The transmission
interval can also be reset to the normal system setting once the alarm is cleared.
To create a new alarm, click the plus icon and a new alarm will be added. To remove an alarm once it

is created, select the alarm in question on the left side of the alarm panel and click the delete icon .
6 Pairing a Sensing Device to an Omega Link Gateway
Refer to either the Wired or Wireless instructions to pair an Omega Link Smart Probe & Interface to an Omega Link
Gateway. Before continuing to the pairing instructions, ensure the following prerequisites are met:
•Ensure that the Omega Link Gateway has been properly setup, powered on, and in close physical proximity.
•(For Wired pairing) Ensure the user has access to a PC and the internal Gateway UI (refer to the Omega Link
Gateway manual for instructions on how to access the internal Gateway UI).
6.1 Wireless Pairing
Pairing a wireless Smart Interface (IF-006) with probe attached is made easy with a one-button pairing system
between the IF-006 and the Omega Link Gateway.
Step 1: When the Smart Probe and relevant accessories have been securely connected to the IF-006, push the
pairing button once on the IF-006. The LED status indicator will blink green indicating the device is in Pairing
Mode.
Step 2: Quickly push the pairing button on the Omega Link Gateway. The LED on the Gateway will blink green
indicating the Gateway is in Pairing Mode.
When the IF-006 or Smart Sensor has been successfully paired to the Omega Link Gateway, the LED will stop
blinking on both devices. Readings for the newly added device will then appear on the Omega Link Cloud or OEG
interface.
6.2 Wired Pairing
Wired Smart Probes connected directly to an Omega Link Gateway with an IF-001 cable or IF-002 will need to be
added to the Gateway Internal User Interface. The Connected Devices tab is the default page set once you are
signed in to the internal gateway UI. From here, you can add devices to your gateway to have them appear in your
Omega Link Cloud account.
Figure 84: Gateway Internal User Interface

7 Appendix: SP-003/SP-004 Registers
The following Appendix provides the registers and list index for the Omega Link SP-003/SP-004 Environmental
Monitoring Smart Probe. This information is intended to aid users who will be making configurations and adjustments
to their Omega Link SP-003/SP-004 Environmental Monitoring Smart Probe through the Command Line Interface or
other custom interfaces.
Smart Probe devices share a common platform architecture that provides extensive monitoring and control
capabilities through a set of platform generic registers. These registers may be accessed using I2C based commands
directly to the Smart Probe devices or through a set of Modbus based registers when using Omega Interface devices.
Refer to the Smart Sensor Device Interface manual for further information.
When powered on or after a device reset each Smart Sensor based device will enumerate 1 or more sensor instances
which are described by the device specific Sensor Descriptors which include configuration options, measurement type
and units of measure for the corresponding sensor values. Additional sensor information is provided in sensor specific
IPSO object descriptions which include extended measurement type, precision and tracking of minimum/maximum
readings. Sensors are always enumerated in the order Apparent Heat (EH), Dewpoint (D), Temperature (T), Relative
Humidity (RH), Barometric Pressure (P) and DIO. Each enumerated Sensor has a Descriptor Base address location and
a Sensor IPSO / Configuration structure address location based on the sensor mix selected.

7.2 Sensor Names
Each sensor has a name. The default names for the outputs are created based on the value being measured. The
default names may be overwritten, such as ‘Room_Temp’ or ‘Oven_Temp’. Names are restricted to 16 characters.
