PCI-2513 User's Guide Installing the PCI-2513 3. To test your installation and configure your board, run the InstaCal utility installed in the previous section. Refer to the Quick Start Guide that came with your board for information on how to initially set up and load InstaCal. If your board has been powered-off for more than 10 minutes, allow your computer to warm up for at least 30 minutes before acquiring data. This warm-up period is required in order for the board to achieve its rated

PCI-2513 User's Guide Functional Details Bus mastering DMA The PCI-2513 supports bus mastering DMA. With multiple DMA channels, analog, digital, and counter input data, as well as digital output data, can flow between the PC and the PCI-2513 without consuming valuable CPU time. The driver supplied with the PCI-2513 automatically uses bus mastering DMA to efficiently conduct I/O from the PC to the PCI-2513. Analog input The PCI-2513 has a 16-bit, 1-MHz A/D coupled with 16 single-ended, or

PCI-2513 User's Guide Functional Details Digital I/O Twenty-four TTL-level digital I/O lines are included in each PCI-2513. You can program digital I/O in 8-bit groups as either inputs or outputs and scan them in several modes (see "Digital input scanning" below). You can access input ports asynchronously from the PC at any time, including when a scanned acquisition is occurring. Digital input scanning Digital input ports can be read asynchronously before, during, or after an analog input

PCI-2513 User's Guide Functional Details 3. Bring the analog input signal toward the desired threshold. When the input signal 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 2.5% of the full-scale range away from the desired threshold. For example, if you are using the ±2 V full-scale range (gain = 5), and you want to trigger at +1 V on the rising edge, you would set the an

PCI-2513 User's Guide Functional Details Pre-triggering and post-triggering modes The PCI-2513 supports four modes of pre-triggering and post-triggering, providing a wide-variety of options to accommodate any measurement requirement. When using pre-trigger, you must use software-based triggering to initiate an acquisition. No pre-trigger, post-trigger stop event. In this simple mode, data acquisition starts when the trigger is received, and the acquisition stops when the stop- trigger

PCI-2513 User's Guide Functional Details Mapped channels A mapped channel is one of four counter input signals that can get multiplexed into a counter module. The mapped channel can participate with the counter's input signal by gating the counter, latching the counter, and so on. The four possible choices for the mapped channel are the four counter input signals (post-debounce). A mapped channel can be used to: gate the counter decrement the counter latch to current count to the coun

PCI-2513 User's Guide Functional Details Gating "on" mode Sets the gating option to "on" for the mapped channel, enabling the mapped channel to gate the counter. Any counter can be gated by the mapped channel. When the mapped channel is high, the counter is enabled. When the mapped channel is low, the counter is disabled (but holds the count value). The mapped channel can be any counter input channel other than the counter being gated. Decrement "on" mode Sets the counter decrement optio
