ADLINK PCI-8124-C - Manual (Page 13)

Introduction 3
1.1 Features
 PCI Rev 2.2, 32-bit/33Mhz Compliment
 Support both PCI-X (3.3V) and PCI (5V) slots
 Support 4-bit board ID for multiple boards in one system
 4 differential quardrature encoder counter input channels
 Each encoder counter input pair supports 1/2/4x A/B phase, dual
pulse (CW/CCW) and signed pulse (OUT/DIR) modes
 Internal digital filter
 4 trigger output channels via both open collector and TTL pins
 Trigger pulse width is software programmable from 0.1µs to
3.2765ms
 Each trigger output channel is selected from all comparators, man-
ual trigger commands, EZ signal and timers by demands
 4 trigger counters that can observe the accuracy of the trigger out-
put pulse quantity
 4 comparators for comparing encoder counter and FIFO data
 10 comparators for comparing encoder counter and linear data
 Each encoder counter source is selected from encoder input pins
or timers
 Comparator data is updated by next FIFO data or linear data when
encoder counter is compared and trigger is outputted
 14 comparators can select one of 4 trigger output channels individ-
ually
 4 channel TTL output pins for general purpose output or trigger
output
 4 channel TTL input pins for general purpose or timer start signal
 4 channel high speed latch input pins for counters
 EZ and Latch input pins can be used for general purpose input
 Latch input logic is selectable by rising or falling edge
 Encoder counter clear via EZ input pin as zero operation
 Programmable interrupt sources from linear data finished, trig-
gered, FIFO empty/full/low, latched, TTL input on.
 Switch setting for trigger output default level while power on
 Trigger output pin logic programmable
 Provide DLL and driver to support Windows 2K/XP/Vista
