PCI-2513 User's Guide Functional Details 15 Bus mastering DMA The PCI-2513 supports bus mastering DMA. With multiple DMA channels, analog, digital, and co unter input data, as well as digital out put data, ca n flow bet ween the PC and the PCI- 2513 without consum ing valuable CPU time.
PCI-2513 User's Guide Functional Details 16 Digital I/O Twenty-four TTL-level digital I/O lines are in cluded in each PCI-2513. You can program digital I/O in 8-bit groups as either inputs or outputs and scan the m in several modes (see " Digital input scanning " below).
PCI-2513 User's Guide Functional Details 17 3. Bring the analog input signal to ward the desired threshold. When the input sig nal is at the threshold (± some tolerance) the sweep will be triggered. 4. Before re-arming the trigger, again move the analog input signal to a level that is more than 2.
PCI-2513 User's Guide Functional Details 18 Pre-triggering and post-triggering modes The PCI-2513 suppo rts four modes o f pre-triggering and post-triggering , providing a wide-variety of options to accommodate any measurem ent re quirement. When using pre-trigger, you must use software-b ased triggering to initiate an acquisition.
PCI-2513 User's Guide Functional Details 19 Mapped channels A mapped channel is one of four coun ter input signals that can get multiplexed into a coun ter module. The mapped channel can particip ate with the counter's in put si gnal by gating the counter, latch ing the counter, and so on.
PCI-2513 User's Guide Functional Details 20 Gating "on" mode Sets the gatin g option t o "on" fo r the mapped channel, enabl ing the m apped chan nel to gat e the counter. Any counte r can be gat ed by t he mapped cha nnel. When t he ma pped channel is high , the counter is enabled.

PCI-2513 User's Guide Functional Details 22 Debounce mode comparisons Figure 9 shows how the two modes interpret the same input sig nal, which exhibits glitches. Notice that the trigger before stable mode recognizes more glitches than the trigger after stable mode.
PCI-2513 User's Guide Functional Details 23 Figure 11. Optimal debounce time for trigger after stable mode Timer outputs Two 16-bit timer outputs are built into ev ery 3000 series board. Each timer is capable of generating a different square wave with a program mable frequ ency in the ra nge of 16 Hz to 1 MHz.
PCI-2513 User's Guide Functional Details 24 Using detection setpoints for output control What are detection setpoints? With the PCI- 2513's setpoi nt configurati on feature, y ou can confi gure up to 16 detect ion setpoi nts associated with channels in a scan group.
PCI-2513 User's Guide Functional Details 25 Action - driven by condition Compare X to: Setpoint definiti on (choose one) Upda te conditions: Limit A or Li mit B Equal to A (X = A) Below A.
PCI-2513 User's Guide Functional Details 26 Setpoint configuration You program all setpoints as part of the pre-acquisition setup, similar to setting up an external trigger. Since each setpoint acts on 16-bit data, each ha s two 16-bit c ompare values: a high limit ( limit A ) and a low limit ( limit B ).
PCI-2513 User's Guide Functional Details 27 Using the setpoint status register You can use the setpoint stat us register to check the current state of the 16 pos sible setpoints. In the register, Setpoint 0 is the least-significant bit an d Setpoint 15 is the m ost-significant bi t.
PCI-2513 User's Guide Functional Details 28 You can program control outputs program med on each setpoint, and use th e de tection for channel 4 to update the FIRSTPORTC digital output port with o.

PCI-2513 User's Guide Functional Details 30 inside the window . There is one update value that g ets applied when the inp ut values are less than the w indow and a different update value that ge ts applied when the input valu es are greater than the window.
PCI-2513 User's Guide Functional Details 31 There are three possible sol utions for o vercoming t his problem : Shorten the scan period to give m ore timing resol ution on the c ounter values or analog va lues. Widen the setpoint window by increasing limit A and/or lowering limit B.
32 Chapter 4 Calibrating the PCI-2513 Every range of a PCI-2513 device is calibrated at the f actory using a digital NIS T traceable calibration method. This method works by st oring a correcti on factor for eac h range on the unit at the time of calibration.
