1. Introduction

1.1 General Description

The model LCIC-WIM is a very High Speed, Intelligent Load Cell

Interface Card with USB/RS232/RS485. Besides its basic mode – named

below as the general mode – the board includes an integral Fill Mode

supplying an independent filling control. The board is intelligent and

powerful enough for OEM customers – it is ready to accept piggy-back

modules and/or embedded applications for OEM special requirements.

1.2 Typical Applications

• Dynamic weighing – vehicles, livestock

• Dynamic force measurement

• High speed checkweighing

• High speed filling / batching

• Beltweighing

• Force measurement / Press Machines

• WIM-Monitor for analysis of dynamic systems

2. Installing the board in the PC

(The following description refers to Windows XP. Obviously, on

another operating system it might be different.)

1. Make sure that all installation files have been copied to your

hard disk to a new folder, say, LCIC-WIM.

2. Connect the LCIC-WIM board to your PC.

3. The ‘Found New Hardware Wizard’ appears.

Select the last option like this:

Click ‘Next’.

4. Select the second option, click ‘Next’ and browse to the

“FTDI - VCP (Virtual COM Port) Driver” folder (under the

folder where you copied the installation files in step 1).

Click ‘Next’.

5. After a while, you’ll have this display:

Click ‘Finish’.

Notes

1. It might occur that the wizard will return to step 3,

requiring to repeat the process. This is normal, just repeat

steps 3-5.

2. You may watch the new driver in ‘Add/Remove programs’:
