FUNCTIONAL DESCRIPTION
The 16-Bit PMC-16AISS16AO2 analog I/O module samples and digitizes 16 input channels
simultaneously at rates up to 1.0 million samples per second per channel, and the resulting 16-bit
sampled data is available to the PCI bus through a 256K-Sample FIFO buffer. Sampling can becontrolled in groups of 1 through 16 channels, and the sample clock can be generated either froman internal rate generator, or by software or an external source. Both burst and continuous
sampling modes are supported, and input ranges are software-selectable as ±10V, ±5V or ±2.5V.
The inputs are divided into two channel groups, with an independent software-controlled range
assignable to each group.
Two analog output channels provide software-selected output ranges of ±2.5V, ±5V or ±10V thatare independent of the input range assignments. The outputs are accessed either directly throughtwo dedicated control registers, or through a 256K-Sample FIFO buffer for waveform generation.
Six bidirectional digital I/O lines are programmable as inputs or outputs. Output clocking can besynchronized to analog input sampling.
On-demand autocalibration determines and applies offset and gain correction values for all input
and output channels. A selftest input switching network routes output channels or calibrationreference signals to the analog inputs, and permits board integrity to be verified by the host.

Local BusFigure 1. PMC-16AISS16AO2; Functional Organization
This product is functionally compatible with the IEEE PCI local bus specification Revision 2.3, andsupports the "plug-n-play" initialization concept. System connections are made at the front panel
through a high-density dual-ribbon 80-pin connector. Power requirements consist of +5 VDC incompliance with the PCI specification, and analog power voltages are generated internally. All
operational parameters are software configurable. Operation over the specified temperature range
is achieved with conventional air cooling.
