	* the conversion function takes a new parameter: d_ReferenceVoltage, 
	whose value can be inquired with IOCTL CMD_APCI3200_ReadReferenceVoltage 
	or kernel function i_APCI3200_ReadReferenceVoltage()
	This allows support of several generations of board without recompiling.
	Please take a look at sample apci3200_temperature.c

* 2008/10/15: SN
	* changed return value on timeout error
	functions now return -EIO (Input/Output error) instead of -1 (EACESS) 

* 2008/04/07: SN
    support for differencial connection in SCAN mode for THERMOCOUPLE
    * added field l_DiffSingSelected to "struct InitTemperatureModule_t" 
	  in IOCTL command CMD_APCI3200_InitScanModuleAcquisitionSensor
    * added parameter b_DiffSingSelected to KAPI function i_APCI3200_InitScanModuleAcquisitionSensor
      client modules must be adapted and recompiled
