    keyword=HAPPEX DAQ: Changed bmp12 to 18-bit ADC

    
    After taking several runs with bmp10 connected to an 18-bit ADC, we've decided 
    the data looks good and that bpm12 should be moved to this ADC.
    
    I put the bpm10 signals back where they were (16-bit ADC 11) and moved the 
    bpm12 signals from adc7 to adcx1.
    
    The signal for each BMP12 signal is about 85K channels. This leaves >100K 
    channels to play with. This should be fine even if the gain settings go back to 
    the way that they were saturating before.
    
    This change began in run 12161.
