1.System Requirements

- Windows 98 / 2000 / ME / XP
- a free USB interface

2.Introduction

Before you can use the DMX-USB you have to install two drivers. These drivers enable your application software to communicate with the DMX-USB via a virtual communications port (VCP).

The first driver is a USB serial converter which establishes the connection to the DMX-USB through the USB interface and makes the data transfer availably to a virtual communications port (VCP).

The second driver is this virtual communications port (VCP) which allows your application software to contact the DMX-USB.

All required files can be found on the CD provided.

3.Install the Driver

To install the driver:
Leave your PC switched on and use the USB cable to connect the DMX-USB to your PC. Windows detects new hardware. Please follow the on-screen instructions and install the driver from the CD provided. The second driver should be installed the same way. The driver installation is described in detail in
Appendix A.

4.View and Change the COM Port

Check in the
Device Manager which COM port the VCP has been set to so that you know which COM port your application software can use to address the DMX-USB. Proceed as follows:

Go to the Control Panel  in Windows. Go to the Device Manager (via System and Hardware). NB: How you get there, depends on your Windows version. Use the online help if required.


You will see Mitutoyo USB Serial Converter and DMX Serial Port listed. The DMX Serial Port indicates the COM port number you also have to specify in your application software, in this case COM4.

If you want to change the COM port number, right-click on DMX Serial Port and in the pull-down menu on Properties. In this window click on the Port Settings tab and then on Advanced...
You can now choose a different COM port. Apply your changes by clicking on all OK. Make sure, however, that you didn’t change any of the other options by mistake.
Detailed instructions can be found in
Appendix B.

5.Deinstall the Driver

You only have to deinstall the driver if you don’t want to use the DMX-USB anymore in the future. This frees the COM port and disk space on your PC.

Caution: After deinstall the driver all other devices using the same driver (e. g. Bobe-Box) also don’t work anymore. So, only deinstall the driver if you are sure that no other device uses the same driver anymore.

Remove the DMX-USB from your PC. Go to the Control Panel  in Windows. Double-click on Add or Remove Programs. Click on FTDI USB Serial Converter Drivers and then on Change/Remove.


In the next window click on
Continue and Finish.

6.Using Several DMX-USB Devices

In principle it is possible to use several DMX-USB devices with one PC. However, you have to install the driver for each additional device and will end up with an additional VCP each time. See View and Change the Communications Port.
Caution: Win98 may permit only one driver installation. In that case you can only work with one device.

Appendix A:

 

The installation depicted here took place under Windows2000. It is similar for other Windows versions.

 

The device name is displayed.



Click on Continue.




Select the option that searches for a driver (if required) and click on Continue.




Let the system search the CD provided. Click on Continue.


The system should find the ftdibus.inf file for the USB Serial Converter. Click on Continue to install the correct driver.


Click on Finish. Then new hardware is discovered a second time.


Proceed as you did with the first driver. The only difference is that the system now needs to find the ftdiport.inf file for the virtual communications port.


The driver installation is now complete.
