Procedure for Programming WIM Cards

Equipment:

USB A to USB B Cable

Precision Calibrator

WIM card Power supply

Prior to calibration and WIM Parameter configuration three applications are needed for this procedure. Note that the driver and applications only work in Windows 7.

1.) LCIC-WIM-Calibration v 3.062.) LCIC-WIM PARM-v1.043.) LCIC-WIM SETTINGS V2.37

The procedures for installing the applications can be found in the Transcore server: PTC/LPU/WIM-LCIC/Latest Software and Firmware/Software.

In the above location there are three folders:

SETUP LCIC-WIM Calibration

SETUP LCIC-WIM PARM

SETUP LCIC-SETTINGS

In addition the driver for the WIM card needs to be installed in the PC. Located in the PTC/LPU WIM-LCIC/Latest Software/Driver. Install this file CDM v2.12.00 WHQL Certified.exe.

After applications and driver are installed Calibration can begin.

Connect the Precision Calibrator and to the WIM card’s DB 9 connector labeled Load Cell, as shown in figure 1.

Connect the USB B to the WIM Card’s USB B connector as shown in figure 2.

Connect the power supply to the WIM card as shown in Figure 3.

The WIM card LED display will light and display a random value, shown in figure 3.

Let the drivers install first and then select the proper port as shown in the image above and click start.

Calibration Procedure

Prior to running LCIC-Calibration once power is applied Windows will load the driver for the WIM Card. The following screen will be seen. Once the

driver has been loaded the programming can begin.

LCIC –Calibration ICON

Click on ICON shown below

The following screen will appear, click on OK.

The following screen will appear, highlight the USB port. This must be done quicklyor application will terminate, and the procedure will need to be restarted.

The following screen will appear, Click next see screen below

Click the down arrow box and change g (grams) to lb (pounds) and change the 16 to 20,000 in Full Load and Maximum Applied parameters.As shown below

Click next

Set the Precision Calibrator value using the right hand knob to 0. Then click on ZERO Next is grayed out. After Zero has been set, Next will not be grayed out and the next procedure can begin.

Click Next

The following screen will appear

Enter the value 20000 and click on ready

The screen will shown that Ready is Green and Next is not grayed out.Click on Next

The following screen will be shown Click on Save to Board

The

following screen will be shown. Click on Yes.

The following screen will appear, programming the calibration parameters in progress.

When completed the following screen will appear. The calibration settings have been saved to the board. Click Yes to exit

Procedures for Uploaded predefined Settings parameters to the WIM Card

The following 2 screens will be shown

Click on PARM ICON

At this point an explanation is needed regarding the file shown in the Library box on the left hand side of the screen. A pre-existing file was created by manually entering the parameters using the Settings program.

Since this manual process has the potential for introducing errors, a WIM card was programmed with the required parameters, verified and uploaded to the pre-defined directory. Since no parameters need to be changed the same file is used to program the WIM card. The only reason the Settings program is used as a QA process to verify that the parameters have been programmed.

After Highlighting the file the following screen will appear. Click on Yes

The following screen will appear

Click on Download parameters(File ->Board) The screen shown below will appear

The dialog box is indicating that the file selected will override the existing file on the board. Click on Yes. Th screen below will appear the process has begun.

When completed the screen below will appear. Click on OK

The following screen will appear. Click on the x at the top right.

The screen shown below will appear Click on Yes to exit

Click on SETTINGS ICON

Click on the Settings ICON as shown on the screen image below.

The program will begin to load

After the program is running the following screen will appear.

The parameters shown are specific to the requirements for Transcore’s LPU system.

Once parameters have been verified the program can be closed and the WIM disconnected from all devices.

From this point you can repeat all the above procedures to program additional WIM cards.
