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.
Ensure that the signal leads have been installed into the appropriate terminal blocks. Some sensor
Note:
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. In such a case, the indicator may display a message that the
load is too high or too low, even if the applied load is correct. Switching the leads may fix the issue. Lead
assignments should be verified with the load cell manufacturer.
The PTA 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 PTA adapter by loosening two Phillips head screws and
removing the cover, as shown in the image below:
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 PTA housing, as illustrated below:
5. Reinstall the cover and tighten the two Phillips screws.
3 SOFTWARE INSTALLATION
The PTA adapter is programmed by a PC running the included software utility, Plug & Test Adapter
Configuration. Communication is achieved through a Mark-10 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, or the software may
be downloaded from the Mark-10 website. 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 Mark-10 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
Mark-10 Model PTA Plug & TestTM Adapter User’s Guide
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 > Mark-10 Software >Plug & Test Adapter Configuration.
4 USING THE SOFTWARE
When software installation has been completed, plug the PTA adapter into the indicator, and connect a
USB or RS-232 cable between the indicator and the PC.

COM Port
Select the appropriate COM port from the dropdown list. Clicking Refresh updates the list with all
installed ports. The COM port associated with the indicator can be identified under the Ports sub-section
of Device Manager in Windows.
Baud Rate
Select the baud rate of the serial port. The default setting is 9600 baud. Be sure to configure the baud
rate to match that of the indicator.
4.3 Force / Torque Capacities & Resolutions
1
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
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 5i & 7i or Model 3i 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.
Note: This software does not allow the user overwrite the configuration of a standard Mark-10
force or torque sensor.
4.4 Read Indicator & Adapter
Use this screen to view information about the sensor and indicator. Click Read to view the indicator
model number, serial number, and firmware version. The sensor’s identification number, serial number,
direction(s), capacities, and resolutions are also visible.
