ENGINEERS building machine vision systems now can trigger and synchronise multiple IEEE 1394 (FireWire) cameras without requiring additional digital I/O or custom circuitry using the new National Instruments PCI-8254R image acquisition board.
The NI PCI-8254R board, which features NI reconfigurable I/O technology, combines an IEEE 1394 host adaptor with the digital I/O required for industrial control and communication.
Traditionally, engineers developing machine vision systems with FireWire were required to purchase extra hardware or build custom circuitry to synchronise their system components.
With the new PCI-8254R board, engineers can access 29 digital I/O lines for synchronising vision components such as cameras, triggers and lights.
In addition, they can use quadrature encoder inputs, pulse generation lines and general-purpose digital I/O for communicating with actuators, PLCs and NI programmable automation controllers (PACs).
To help integrate and troubleshoot signals, NI also offers an I/O terminal block and prototyping accessory that simulates inputs and displays outputs on LEDs.
Engineers can extend the functionality of the PCI-8254R board by taking advantage of NI reconfigurable I/O technology. Using the NI LabVIEW FPGA Module, engineers can customise the board's 29 digital I/O lines to perform a wider variety of packaging inspection, assembly verification and robot control applications.
The PCI-8254R image acquisition board includes two IEEE 1394a ports and the NI-IMAQ for IEEE 1394 cameras driver software to help engineers access, configure and acquire images from up to 16 cameras.
