2Introduction
The Layer N SP-010 Load Cell Smart Probe provides an easy way to integrate your bridge devices to the Layer N Ecosystem.
The SP-010 accepts 4-wire bridge sensors through its M12 4-pin connector and Layer N Smart Interfaces through its M12 8-
pin connector. The M12-S-M-FM accessory connector can be utilized to easily connect wire leads to your SP-010.
The Load Cell interface supports most common load cell impedances and sensitivities. The SP-010 uses a constant current
for excitation based on the bridge impedance. The bridge impedance is automatically detected when the SP-010 is first
turned on and can be re-tuned at any time using the free SYNC software package. The excitation current is only applied
during measurements to limit self-heating effects and allow for battery powered operation.
The SYNC software also allows customizing the sensitivity of the bridge in mV/V and the maximum range of the bridge in
the specific units of measure. The default unit of measure is kg and can also be customized. TARE and 2 Point Linearization
are also available through SYNC.
The Layer N SP-010 features 2 configurable digital I/O pins. These can be used for a myriad of applications including
initiating the TARE function, driving relays, physical alarms, or sensing dry contacts like door switches. The SP-010 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.

4SYNC Configuration
Layer N Smart Probe products are easily configurable through SYNC configuration software. Ensure SYNC is running on your
Windows OS computer before continuing. Connect your SP-010 to your computer through your Layer N Smart Interface.
Note: SYNC is available to download for free on the OMEGA website.
4.1 Connecting to SYNC - Automatic Detect
Once the SP-010 and Layer N Smart Interface are connected to your computer, SYNC will automatically detect it and begin
displaying readings.
Note: If you have successfully connected your SP-010 to SYNC and have readings appearing in SYNC, skip ahead to
the section titled Load Cell Interface.
4.2 Connecting to SYNC – Manual
If SYNC does not automatically detect your 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.
4.2.1 Communication Interface
Set the communication parameters for the Layer N 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-010 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.

• Device Address: If your Smart Interface is part of a Network, enter the Network Address here. The default network
address is 1 for most devices. Please refer to the manual of your Smart Interface for more
information.
Note: The default Device Address is 1.
• Device IP or Port: The COM port number that your device is connected to on your computer.
Important: The following parameters should NOT be changed. These settings should NOT be changed unless the
configuration has been done on the interface.
• BaudRate: Controls bits per second
• DataBits: The number of ‘bits’ in each character sent.
• Parity: A means of checking correctness of character by adding an extra ‘bit’ to the character and setting the value
based on all the other bits in the character.
• StopBits: The number of ‘bits’ used to indicate the end of the character.
Once you have completed setting the communication parameters for your device, click Finish.
4.3 Load Cell Interface
The SP-010 measures the bridge voltage to determine the applied force using bridge characteristics provided by the user. To
configure the settings on your SP-010, follow these instructions:
Step 1: Click the Input Configuration Tab in SYNC and select the Load Cell input type form the Type drop down.
Step 2: Set the Parameters of your Load Cell to your preferred settings.
Parameter
Description

Update this parameter to TARE bridge
If the Bridge Impedance is set to 0 the SP-010 will automatically calculate the impedance on the next device reset or power
cycle.

4.3.1 2-Point Calibration
A 2-point linearization correction may be applied using either known scaling values or reference weights. 2-Point
Calibration can be performed as described below:
Step 1: From the Load Cell Input interface on SYNC, click Calibrate.
Step 2: Place your low reference and click Capture next to Low Reading. This will capture the measurement for
the low reference in the low reading box. Enter your actual low reference weight in the Low Actual Box.
Step 3: Place your high reference and click Capture next to High Reading. This will capture the measurement for
the high reference in the high reading box. Enter your high reference weight in the High Actual Box.
Step 4: Click Calibrate to save your calibration.
Note: Clicking Calibrate or Clear Calibration will clear the TARE offset.
4.4 Setting Alarms
Alarms are set by clicking the icon in SYNC on the desired input signal found in the Inputs Configuration Tab. Setup
the threshold and alarm type in the Condition section and then select which output to turn on in the Action section. The
alarm can be set to be latching or non-latching in the Recovery section.
