Initialization of Clarinet-Book USB Ethernet 10/100

Clarinet Book USB Ethernet 10/100: operating  side

 

L1 The LED L1 (Red color) reflects the battery and charger state:
  • Continuously ON: charge process completed or interrupted
  • 2 flashes: high current charging
  • 1 flash: trickle charge

The LEDs flash briefly every 3-4 seconds.
The charge process is halted:

  • When the CLARINET is running a profile
  • When the battery is fully charged
  • During the CLARINET initialization (about 30s after power-on, or loader op.)

Normal operating state is "continuously ON".
If the LED is continuously OFF, the battery is flat

ID
(Coding wheel)		 Several Clarinet modules connected to the PC must have different ID's (from 1 to 7), set by the coding wheel. After changing the value selected on the coding wheel the Clarinet Loader must be executed.
ON  Pushing the button (through the hole) resets the Clarinet-Book unit.
Power To connect the external Power-adapter unit.
USB To connect the USB cable (type B)
SIG For maintenance purposes
L2 The LED L2 (green) reflects the USB state (configuration and power):
  • 1 flash: USB OK - powered by USB
  • 2 flashes: USB OK - powered by external power adapter
  • 3 flashes: USB OK - powered by battery
  • 4 flashes: USB unconfigured - powered by external power adapter
  • 5 flashes: USB unconfigured - powered by battery

The LEDs flash briefly every 3-4 seconds.
Normal operating states are states 1 or 2.

 

Clarinet Book USB Ethernet 10/100: interface side

 

100 M ON= running a profile with the 100 M mode selected.
RJ 45 selection ON= running a profile with the RJ45 mode selected.
AUI selection ON= running a profile with the AUI mode selected.

The Clarinet-Book can be connected to a 10B2 BNC connector by using:

  • An external transceiver AUI-10B2 
  • The external Power-adapter unit of the Clarinet-Book which provides the power to the transceiver
Ethernet interface The LEDs display the interface activities:
  • TX: data to be transmitted to the Output direction
  • RX: data received on the Input direction
  • LINK: "Good link" Link integrity status.(Twist Pair)
  • POL: "Polarity" Detection of Pulse with reverse polarity (Twist Pair)
  • COL: Collision Detection (Twist Pair or AUI)


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

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

CLARINET automatically shut-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 to the PC to boot

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