1.2 General Overview
The DFG-RSA adapter is designed to interface a user-supplied load cell, force sensor, or torque sensor
with Omega indicators. The adapter may be programmed to the appropriate load capacity with a software
utility through USB or RS-232 connection to the indicator.
All configuration and calibration information is saved within the adapter, allowing for interchangeability
between multiple sensors (including certain standard Omega sensors).
1.3 Compatible Equipment
The DFG-RSA adapter is compatible with load cells and sensors meeting the following specifications:



Type: Full bridge
Resistance: 300 – 1000 ohms
Sensitivity: 1 – 3 mV/V full scale
2 MECHANICAL SETUP
Sensors meeting the above specifications are supplied with a cable with four leads, for the following
functions:
EXCITATION +
EXCITATION –
SIGNAL +
SIGNAL –
These leads are typically color coded. Refer to the sensor’s data sheet for details.
Note: Ensure that the signal leads have been installed into the appropriate terminal blocks. Some sensor
manufacturers consider SIGNAL + to be a compression value, while others consider it to be a tension
value. If these leads are installed incorrectly, the indicator will display the opposite tension/compression
indicator, and calibration cannot take place. Switching the leads will fix the issue. Refer to the indicators’
user’s guides for details.
The DFG-RSA adapter contains a circuit board with a screw terminal block to allow for the connection of
these leads. Refer to the following procedure for setup instructions:
1. Access the circuit board inside the DFG-RSA adapter by loosening two Phillips head screws and
removing the cover, as shown in the image below:

User’s Guide
The screw terminal block will be visible, along with labels referencing the functions listed above:
2. Feed the four leads through the supplied strain relief (pictured above) and into the body of the
adapter.
3. Using a flat screwdriver, loosen the four screws in the terminal block until the sensor leads can be
inserted into the appropriate receptacles. After insertion of the leads, tighten the screws, as
shown in the image below:

4. Install the strain relief by pressing it into the receptacle in the DFG-RSA housing, as illustrated
below:
5. Reinstall the cover and tighten the two Phillips screws.
3 SOFTWARE INSTALLATION
The DFG-RSA adapter is programmed by a PC running the included software utility. Communication is
achieved through an Omega indicator and a USB or RS-232 connection.
3.1 Computer requirements
A PC running Windows 2000 or later operating system with screen resolution of 1024 x 768 minimum, is
required to run the software. An RS-232C serial port or USB port (virtual COM port) is required to
communicate with the indicator. A CD-ROM drive is needed for software installation. If USB
communication is required, be sure to install the appropriate USB driver. A USB driver and user’s guide
are provided in the contents of the Resource CD.
3.2 Installation instructions
Installing from a CD
Insert the CD into the computer’s CD-ROM drive. If AutoRun is enabled on the computer, the
setup program will run automatically. If not, the setup program may be run manually. Click the
START button on the Windows task bar, select “Run…”, type “D:setup” in the dialog box and
press ENTER. Alternately, using My Computer or Windows Explorer, navigate to the CD-ROM
drive and double-click the file “setup.exe”. Follow the prompts on the screen to install the
software.
Installing from the website
If downloading from the website, it is important to unzip/extract the files first, and then run the file
“setup.exe”. Follow the prompts on the screen to install the software.
3.3 Running the software
When the installation is complete, the program can be found in:
Programs > Omega Software > DFG-RSA Adapter Configuration
5
Model DFG-RSA Configurable Load Cell Adapter
User’s Guide
4 USING THE SOFTWARE
When software installation has been completed, plug the DFG-RSA adapter into the indicator, and
connect a USB or RS-232 cable between the indicator and the PC.

Use the Force Capacities & Resolutions and Torque Capacities & Resolutions screens to program
the capacity appropriate for the sensor. The number of available units of measurement and displayed
resolution depend on the indicator being used. Refer to Section 5 for detailed information.
Refer to the following procedure:
1. Select the appropriate capacity. Use the
and
arrows to scroll through additional
capacities. The Capacity table shows the available units of measurement and their corresponding
capacities. The Resolution table displays the increment size for each of the available units.
Select the Model DFG-RS5 or Model DFG-RS3 radio button in the lower right corner of the
screen to display the units and resolutions available for each indicator.
2. The software may be used to configure a bi-directional sensor, such as an S-beam, or single
direction sensor, such as a load button. Select the appropriate direction.
3. Optionally enter an identification number for the sensor. This number will be displayed in the
indicator’s power-up sequence and Information screen.
Note: The identification number may not begin with the letter sequence “MR”.
4. Click Program Adapter. A progress bar is supplied below this button, for visual convenience.
Do not disconnect the communication cable until this process is complete, denoted by the PASS
or FAIL indicator.
