Page 7: Preface
About this User's Guide What you will learn from this user's guide This user's guide explains how to install, configure, and use the PCI-2515 so that you get the most out of its analog input, digital I/O, and counter/timer I/O features. -

±10 V, ±5 V, ±2 V, ±1 V, ±0.5 V, ±0.2 V, and ±0.1V. The PCI-2515 also has two 16-bit, 1 MHz analog output channels with an output range of -10V to +10V. The board has 24 high-speed lines of digital I/O, two timer outputs, and four 32-bit counters. It provides up to 12 MHz scanning on all digital input lines. -
Page 9: Installing The Pci-2515
PCI-2515 Optional components Cables and signal conditioning accessories that are compatible with the PCI-2515 are not included with PCI- 2515 orders, and must be ordered separately. If you ordered any of the following products with your board, they should be included with your shipment. -
Page 10: Additional Documentation
As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the PCI-2515 from its packaging, ground yourself using a wrist strap or by simply touching the computer chassis or other grounded object to eliminate any stored static charge. -
Page 11: Configuring The Hardware
Configuring the hardware All hardware configuration options on the PCI-2515 are software-controlled. You can select some of the configuration options using InstaCal, such as the analog input configuration (16 single-ended or eight differential channels), and the edge used for pacing when using an external clock. -

Page 14: Programming And Developing Applications
2, your PCI-2515 should now be installed and ready for use. Although the board is part of the larger Measurement Computing hardware family, in general there may be no correspondence among registers for different boards. Software written at the register level for other models will not function correctly with your board. -

Page 16: Bus Mastering Dma
The PCI-2515 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-2515 without consuming valuable CPU time. The driver supplied with the PCI-2515 automatically uses bus mastering DMA to efficiently conduct I/O from the PC to the PCI-2515. -
Page 17: Digital I/O
You can also synchronize everything—input scans, DACs, pattern digital outputs—to one clock, which is either internally-generated or externally-applied. Digital I/O Twenty-four TTL-level digital I/O lines are included in each PCI-2515. 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"... -
Page 18: Digital Input Scanning
Digital outputs can be updated asynchronously at anytime before, during, or after an acquisition. You can use two of the 8-bit ports to generate a digital pattern at up to 12 MHz. The PCI-2515 supports digital pattern generation with bus mastering DMA. The digital pattern can be read from PC RAM. -
Page 19: Digital Triggering
Software-based triggering usually results in long period of inactivity between the trigger condition being detected and the data being acquired. However, the PCI-2515 avoids this situation by using pre-trigger data. When software-based-triggering is used, and the PC detects the trigger condition—which may be thousands of readings after the actual occurrence of the signal—the PCI-2515 driver automatically looks back to the location... -
Page 20: Counter Inputs
Counter inputs Four 32-bit counters are built into the PCI-2515. Each counter accepts frequency inputs up to 20 MHz. The counters can concurrently monitor time periods, frequencies, pulses, and other event driven incremental occurrences directly from pulse-generators, limit switches, proximity switches, and magnetic pick-ups. -
Page 21: Counter Modes
Sets the signal on the mapped counter input to latch the count. By default, the start of scan signal—a signal internal to the PCI-2515 pulses once every scan period to indicate the start of a scan group—latches the count, so the count is updated each time a scan is started. -
Page 22: Debounce Modes
PCI-2515 User's Guide Functional Details 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. - Page 23 PCI-2515 User's Guide Functional Details Figure 4-6. Debounce module – trigger after stable mode The following time periods (T1 through T5) pertain to Figure 4-6. In trigger after stable mode, the input signal to the debounce module is required to have a period of stability after an incoming edge, in order for that edge to be accepted (passed through to the counter module.) The debounce time for this example is equal to T2 and T5.
- Page 24 PCI-2515 User's Guide Functional Details Figure 4-8. Example of two debounce modes interpreting the same signal Debounce times should be set according to the amount of instability expected in the input signal. Setting a debounce time that is too short may result in unwanted glitches clocking the counter. Setting a debounce time too long may result in an input signal being rejected entirely.

Page 25: Timer Outputs
Multiple PCI-2515s per PC PCI-2515 features can be replicated up to four times, as up to four boards can be installed in a single host PC. The serial number on each PCI-2515 distinguishes one from another. When multiple PCI-2515s are installed, they can be operated synchronously. -
Page 26: Calibrating The Pci-2515
Calibrating the PCI-2515 Every range of a PCI-2515 device is calibrated at the factory using a digital NIST traceable calibration method. This method works by storing a correction factor for each range on the unit at the time of calibration. For analog inputs, the user can adjust the calibration of the board while it is installed in the acquisition system. -
