Condition Verification: 

  • Yes - Continuously


  • In the case where a connection can not be made with the DRB III using the TechTOOLS application there may be a USB driver conflict or a USB problem.
  • Confirm in the the Safely Remove Hardware Manager (located in the System Tray) that you see the GPIB-USB converter connected. 
    • If the PC sees the GPIB-USB connection here this is usually a good indication that the driver has been installed properly. 
  • However, if at first you do not see the GPIB-USB connection, confirm that the Green power light is on on the GPIB-USB converter.


  • There are 6 USB connections on the DealerCONNECT Dell Client.
  • In most cases you can disconnect the GPIB Protocol converter at the USB connection and move to another USB connection.
    • This USB connection is a Blue ended connector.
  • By moving the GPIB to another USB connection you are forcing the Dell PC to reinstall the GPIB Drivers.
