Windows USB Connectivity and Your Cirrus Noise Measurement Instruments

If you are upgrading your PC to 10 and are using a USB connection to download measurements from your instrument(s), you may need to update the drivers to allow your software to communicate with your instrument.

Please note that the installation of any drivers must be carried out using Full Administrator Access Rights.

If you do not have full administrator access rights, you will not be able to update or install the required drivers.

If you have any questions about the access rights available to you, please contact your IT support.

Instruments with a USB Port

CR:800C & CR:260A Sound Level Meters

The CR:800C and CR:260A instruments use an FTDI Driver which is supplied with the Deaf Defier software installation CD and as part of the software download.

To update the driver:

  • Step 1 – Download the latest driver from the chipset manufacturer website
  • Step 2 – Disconnect the sound level meter from the PC and close the Deaf Defier3 software program completely.
  • Step 3 – Run the driver installation program downloaded in step 1
  • Step 4 – When the installation is complete, connect the Sound level meter to the PC. Windows will detect the new hardware and install the new driver. Deaf Defier3 will now be able to connect to the sound level meter.

RC:110A doseBadge Reader Unit

The RC:110A Reader Unit (USB) uses an FTDI Driver which is supplied with the dBLink software installation CD and as part of the software download available from the Cirrus website.

To update the driver:

  • Step 1 – Download the latest driver from the chipset manufacturer website
    • Click here to download the latest driver. This is available as an executable file (.exe) or a ZIP file.
  • Step 2 – Disconnect the doseBadge Reader from the PC and close the dBLink3 software program completely.
  • Step 3 – Run the driver installation program downloaded in step 1
  • Step 4 – When the installation is complete, connect the RC:110A doseBadge Reader to the PC. Windows will detect the new hardware and install the new driver. dBLink will now be able to connect to the Reader.

Troubleshooting

The steps detailed above will install the correct Windows 7 driver for the RC:110A doseBadge Reader. If when the doseBadge Reader is connected to the PC, Windows 7 cannot find or install the driver, your Reader unit may need an upgrade.

The RC:110A doseBadge Reader units manufactured before 1st July 2009 have a different USB driver in their internal software. This may prevent the new driver from correctly identifying the Reader.

If you are not able to do this, the Reader unit will need to be upgraded by either Cirrus Research plc or an Authorised Service & Calibration Centre.
