Below is a table of configuration values. The Name column is the name which can be used when setting the values using the serial configuration interface.

Note that the name CHM specifies in the configuration interface a 16-bit value which sets the mode for all channels, so for example to enable only channel 1 active and disable the others you would specify hex 0xfffc.

Name	Bits	Description	Expression	Nominal
MASK	[0:7]	Channel mask register LSB=ch 1	n/a	0
CAP	[8:10]	Calibration capacitor select	n/a	0
DISC1	[11:18]	Timing discriminator threshold	(N-128)*2 mV	108 (-40mV)
DISC2	[19:21]	Wilkinson ADC threshold	14+16*N mV	1 (30mV)
HYST	[22:25]	Hysteresis for DISC1	N*1.25 mV	2 ( 2.5mV)
GATE	[26:29]	Wilkinson ADC gate	11+1.5*N ns	6 (20ns)
RDOWN	[30:32]	Wilksonson I(rundown)	2.4+0.7*N uA	5 (5.9uA)
DEADT	[33:35]	Deadtime	74+18.3*N (ns)	7 (535 ns)
CHM	[36:37]	Channel 1 mode (top)	00 - ACTIVE	0 (Active)
	[38:39]	Channel 2 mode	01 - HIGH	0 (Active)
	[40:41]	Channel 3 mode	10 - LOW	0 (Active)
	[42:43]	Channel 4 mode	11 - OFF	0 (Active)
	[44:45]	Channel 5 mode		0 (Active)
	[46:47]	Channel 6 mode		0 (Active)
	[48:49]	Channel 7 mode		0 (Active)
	[50:51]	Channel 8 mode (bottom)		0 (Active)
TOT	[52]	Chip mode	0=ADC 1=TOT	0 (ADC)

Here is a sample python code ​serial_config.py which will set the ASD and TDC to their default settings and store in EEPROM.
