PCI-8124

Advanced 4-CH Encoder Card with High-peed Triggering Function

Features

32-bit PCI bus, Rev. 2.2, 33MHz

Support both PCI-X (3.3V) and PCI (5V) slot

Card index switch selection

Four 32-bit quadrature encoder input and trigger output channels

Trigger output up to 5MHz

Encoder input up to 10MHz

Trigger pulse up to 3.7ms

Encoder input frequency: Up to 5MHz

Trigger output frequency: Up to 1MHz

Encoder input interface: OUT/DIR, CW/CCW, and 1x, 2x, 4x A/B phase

Input / Output circuit source can be selectable: TTL/ Open Collector (with isolation)

Four 32-bit comparators where source can be configurable

Internal high-speed FIFO for 4 32-bit comparators as data reload buffer

Each channel can store 1023K points (32-bit)

Trigger pulse width is software programmable from 0.1 £gs to 3.2765ms

Each trigger output channel is selected from all comparators, manual trigger commands,

EZ signal and timers by demands

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 individually

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 by rising or falling edge

Programmable interrupt sources from linear data finished, triggered, FIFO empty/full/low,

latched, TTL input on.

Switch setting for trigger output default level while power on

Trigger output pin logic programmable

Software Support

Available for Windows Vista32/XP/2000

VB/VC++/BCB/Delphi are recommended programming environment.
