Configuring the DAS-1700 Series
Keithley DAS-1700 Series
Address
The Address property records the I/O port address for the board. The default address
used by DriverLINX is 0x300 hexadecimal or 768 decimal.
The DAS-1700 has a 6-bit DIP switch that sets its base address. Each switch
corresponds to a binary digit in the address. When a switch is up, or in the ON
position, its digit is 0. When it’s down, its digit is 1.
The switches select the value of the 1
st
to the 6
th
digits. The 7
th
to the 10
th
digits of the
address are 0. That is, there are four zeros to the right of the bits represented by the
switches.
For example, the following DIP switch shows the setting for 11 0000 0000
(0x300 hexadecimal or 768 decimal).
Windows NT
Enter your board’s base I/O address. Note: you need a block of sixteen free
addresses. AO models use an additional block of ten addresses starting at
base + 0x400.
Windows 95/98
Under Windows 95/98, Add New Hardware automatically selects an appropriate
address. To change the setting, see “Using the Windows 95/98 Device Manager” on
page 17.
Detect
The Detect property enables and disables DriverLINX’s hardware detection and
testing algorithms. For maximum system reliability, always leave this check-box
marked.
Calibrate
The Calibrate property enables and disables hardware auto-calibration. This option is
grayed-out for the DAS-1700 Series because it does not support automatic
calibration.
