Name	Description	Applicable Boards
current_channel	The channel on which to perform A/D conversions	Diamond-MM-16-AT, Diamond-MM-32X-AT, Diamond-MM-16RP-AT, Diamond-MM-32DX-AT, Diamond-MM-AT, Helios
gain	The gain setting to use for A/D conversions; valid settings are GAIN_1, GAIN_2, GAIN_4, and GAIN_8	Diamond-MM-16-AT, Diamond-MM-32X-AT, Diamond-MM-16RP-AT, Diamond-MM-32DX-AT, Aries, Diamond-MM-AT, Helios
range	The range setting for A/D conversions; this is not to be confused with the term "A/D range" or "input range". Valid settings are RANGE_5 or RANGE_10	Diamond-MM-16-AT, Diamond-MM-32X-AT, Diamond-MM-16RP-AT, Diamond-MM-32DX-AT, Diamond-MM-AT, Helix, DS-MPE-DAQ0804, Zeta, Helios
polarity	The polarity setting to use for A/D conversions; valid settings are BIPOLAR or UNIPOLAR	Diamond-MM-16-AT, Diamond-MM-32X-AT, Diamond-MM-16RP-AT, Diamond-MM-32DX-AT, Aries, Diamond-MM-AT, Helix, DS-MPE-DAQ0804, Zeta, Helios
load_cal	If TRUE, the board will retrieve the calibration settings for the selected A/D range from the EEPROM and store it in the calibration circuit before performing the A/D conversion. This results in higher accuracy but causes a slight delay of a few milliseconds. If FALSE, the board will use the current calibration settings and start the A/D conversion immediately. Once a particular A/D range's calibration settings are loaded into the board, they will remain loaded until the board powers off or a new set of settings is loaded. When the board powers up, it automatically loads the settings defined as the boot mode. The boot mode is set with the autocal function.	Diamond-MM-16-AT, Diamond-MM-32X-AT, Diamond-MM-16RP-AT, Diamond-MM-32DX-AT, Aries, Diamond-MM-AT, Helios
scan_interval	Determines the time delay between consecutive A/D conversions during an A/D scan operation. When you perform an A/D scan, the individual A/D samples will be spaced apart by exactly this amount of time. The time delay affects the maximum possible sample rate. For example, if you want to achieve a 100KHz sample rate, the maximum scan interval is 1/100KHz = 10 microseconds. 0 20 microseconds (default value) 1 15 microseconds 2 10 microseconds 3 5 microseconds 4 9 microseconds 5 4 microseconds	Diamond-MM-16-AT, Diamond-MM-32X-AT, Diamond-MM-16RP-AT, Diamond-MM-32DX-AT, Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
clk	Clock INPUT: 0 = ADSTART=1, 1 = falling edge of P_ADTRIG, 2 = rising edge of conter0, 3 = rising edge of counter1	Helix, DS-MPE-DAQ0804, Zeta, Aries
low_channel	low channel for A/D conversion	Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
high_channel	high channel for A/D conversion	Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
Sedi	0 = single-ended, 1 = differential	Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
Sign	if Differential mode is enabled: 0 = even channel is high; 1 = odd channel is high	Helix, DS-MPE-DAQ0804, Zeta, Helios
ScanEnable	0 = disable, 1 = enable	Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
ProgInt	If ScanInterval is programmable, then ProgInt is the time in nano seconds (0 – 255)	Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
ProgInt	If ScanInterval is programmable, then ProgInt is the time in nano seconds (0 – 255)	Aries, Helix, DS-MPE-DAQ0804, Zeta, Helios
DataBus	0- 8-bit AD data; 1- 16-bit AD data; To enable 16/8 bit AD data read mode(Only Supported for Linux)	DMM32-DX-AT
