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
