2 Introduction
The Omega Link SP-003/SP-004 Environmental Monitoring Smart Probe provides temperature, relative humidity, and
barometric pressure readings. The SP-003-2 and SP-004-2 also offer dewpoint, humidex, and heat index readings.
The SP-003/SP-004 accepts Omega Link Smart Interfaces through its M12 8-pin connector.
The Omega Link SP-003/SP-004 features 2 configurable digital 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 SP-003/SP-004
can also be utilized as an edge controller with autonomous independent decision-making capabilities to generate
local alarms or provide control outputs based on sensor inputs.

4 Hardware Setup
4.1 Connecting to your Omega Link Smart Interface
The SP-003/SP-004 requires an Omega Link Smart Interface to connect to a computer. OMEGA offers a variety of
Smart Interfaces such as the wired IF-001 or wireless IF-006. Use the M12 8-Pin Connector diagram below to connect
your SP-003/SP-004 to your Omega Link Smart Interface. To access discrete I/O, an M12.8.T-SPLIT and an M12.8-S-
M-FM are needed.
Discrete I/O
If the smart probe discrete I/O will be utilized, an M12.8-T-SPLIT and an M12.8-S-M-FM will need to be
connected between the Smart Interface and Smart Probe. Refer to the previous pin diagram and the wiring
diagram below to connect the accessories:
4.2 Bulkhead Mechanical Dimensions in Inches

5 SYNC Configuration
Omega Link Smart Probe products are easily configured through Omega’s free SYNC configuration software. Ensure
SYNC is running on a Windows OS computer before continuing. Connect the SP-003/SP-004 to the computer using
your Omega Link Smart Interface to begin.
Note: SYNC is available to download for free on the OMEGA website.
5.1 Connecting to SYNC - Automatic Detect
Once the SP-003/SP-004 and Omega Link Smart Interface are connected to the computer, SYNC will automatically
detect the probe and begin displaying readings.
Note: If living readings from the SP-003/SP-004 are displayed on SYNC, skip ahead to section 5.3 Input
Configuration.
5.2 Connecting to SYNC – Manual
If SYNC does not automatically detect the device, follow these instructions to manually connect it.
Step 1: Click on the icon located on the top left of the SYNC interface.
Step 2: Proceed through the Add Device Wizard and click End Device / Probe.
Communication Interface
Set the communication parameters for the Omega Link Smart Interface that you are connecting.
Note: The connection type and parameters must be accurate for a proper connection to be
established. Failure to accurately setup communication parameters may result in
communication errors.
•Connection Type: Select the type of connection you have between your SP-003/SP-004 and your computer.
•Command Timeout: The maximum time (in milliseconds) for a command to be completed before the command is
aborted.
Note: The default command timeout is 500 milliseconds. It is recommended that this section be left alone to avoid
communication errors.
