AIM-16. SEL3-SEL0 are typically used for channel, and G2-G0 are used for gain. If no submulitplexer is being used, it is a good idea to use SEL3-SEL0 as ID tags. These values will comprise the top four bits of the data returned from the A/D converter. Manual PCI-A12-16A... -

In DOS, the PCI\SOURCE directory shows the BIOS calls used to determine the address and IRQ assigned to installed PCI devices. In Windows, the Windows sample programs demonstrate querying the registry entries (created by PCIFind and NTIOPCI.SYS during boot-up) to determine this same information. Manual PCI-A12-16A... -

The range of each DAC is set by a block of switches on the board. The ranges correspond to switch settings as follows: Switch Range OFF OFF 0-2.5V OFF OFF OFF 0-5V OFF ON 0-10V OFF ON ±2.5V OFF OFF ON ±5V OFF ON ±10V Manual PCI-A12-16A... - Page 14 C H 7 4-20mA R P 1 R P 2 R P 3 FA C TORY U S E ON LY R P 5 R P 6 R P 7 R P 8 Figure 3-1: Option Selection Map Manual PCI-A12-16A...

D7 set low. In the example above, the control byte to de-tristate the ports would be 01. This register can also be used to tristate the ports without changing their mode, by writing a control byte to Base + 14 with D7 set high. Manual PCI-A12-16A... -

In the case of FIFO based acquisition, this generally means reading enough data from the data FIFO that it is no longer more than half-full. Manual PCI-A12-16A...

Note that in this mode, to achieve the square wave, the counter decrements by two for the total loaded count, then reloads and decrements by two for the second part of the wave form. Manual PCI-A12-16A... - Page 26 In this mode, the counter will start counting after the rising edge of the trigger input and will go low for one clock period when the terminal count is reached. The counter is retriggerable. The output will not go low until the full count after the rising edge of the trigger. Manual PCI-A12-16A...

At the end of the timeout, the counter reaches zero and the counter output goes high. That output will remain high until re- triggered by the gate input.
