Setting-up the Clarinet

Unit Power The Clarinet module connected to the PC can be powered by :
  • A set of batteries normally placed inside the module.
  • The USB connection to the PC (or a HUB device).
  • An external power supply unit.

When the CLARINET is only powered by USB (bus-powered device), it is only trickle charged.
As the NiMH batteries can be deteriorated by overcharging, a full charge process is only done if the battery is detected low at initialization. To force a full-charge process, select 0 on the coding wheel and connect the external power adapter.

Startup THe CLARINET is started up when power is detected on USB bus during the PC power-on sequence, or when a USB connector is plugged in.

The CLARINET automatically shuts-down when USB is suspended (PC powered off, or USB disconnected) after a short delay:

  • 30 s if the device has been configured via USB
  • 3 ' if the device is unconfigured, to give time for the PC to boot

If CLARINET is shutdown with the ON button, the USB cable must be unplugged-plugged to restart it.
