    Configuration Utility Setup The configuration utility is installed separately from the Nicolet brand system. To install it, follow the instructions that came on the Nicolet CD with your Nicolet brand system. NOTE: The User Configuration Utility displays in the read only mode. The amplifier uses a micro USB to USB cable to connect to a computer running the configuration utility.
  • Page 104 Nicolet Systems Configuration Utility The following information can be viewed from the User Configuration Utility dialog. dialog NOTE: Do not disconnect the USB cable from the amplifier while the configuration utility is open. IP Address / Ports NOTE: When you upgrade the firmware, all custom settings will be erased. To avoid this, first export the settings and then update the firmware.
  • Page 105 Configuration Utility Status The Status section displays the current power level of the amplifier and the remaining memory. The memory is displayed in GB, and the power level is displayed as a percentage of the remaining battery life or as “Connected” if the amplifier is connected to AC power.
  • Page 106 Nicolet Systems SSID This section displays the Service Set Identifier. Sampling Frequency The Sampling Frequency section displays the default sampling frequency of the amplifier. This is the sampling frequency that is used for the first study when it is started from the amplifier without connecting to the Nicolet brand system. If the amplifier is connected to the Nicolet brand system and a study is started from the software, the sampling rate selected becomes the new default sampling rate until the amplifier is power cycled.

  • Page 129: Question 1: Why Can't I Select My Amplifier From The Amplifier Selection Screen

    Frequently Asked Questions Question 1: Why can't I select my amplifier from the amplifier selection screen? There are a number of reasons why you may not be able to select an amplifier. The problem is typically indicated in the "Amplifier Details" box at the bottom of the Wireless Amp selection screen.
  • Page 130 Nicolet Systems Problem: The amplifier either has an incompatible headbox type (a 64 channel headbox on a 32 channel amplifier) or there is no headbox attached to the amplifier. This is indicated in the Amplifier Details. Solution: Connect a compatible headbox to the amplifier. If the amplifier is a 32 channel amplifier, the only compatible headboxes are a 32 channel or w10-20HB headbox.
  • Page 131 Frequently Asked Questions Problem: The data on the amplifier was recorded with a different headbox type (only happens on 64 channel amplifier). The amplifier details indicates this. Solution: Connect the correct headbox type to the amplifier to retrieve the data. If you have a 64 channel headbox connected, connect a 32 channel or w10-20HB headbox.
