Onboard Memory

National Instruments has expanded its high-speed digital device family to include the NI 6534 high-performance digital I/O device, which combines pattern I/O, handshaking, and change detection on the same device.

The NI 6534 is available for PCI and PXI/CompactPCI. It delivers 32 lines of 5 V/TTL digital I/O and start and stop triggering. It can transfer in eight, 16 or 32 bits and has two independent data paths with 32 MB of onboard memory per data path.

With the onboard memory, data transfers can be independent of the computer bus for a faster, more reliable transfer rate.

Usd can perform separate operations with the two data paths, including simultaneous input and output.

The NI 6534 includes NI-DAQ 6.9, the latest version of the company's driver software.

The device can transfer data at 80 MBps for pattern I/O or handshaking I/O. With the six different handshaking modes on the device, users can communicate with a peripheral device or an external system.

Users can connect the NI 6534 to a variety of external devices, such as custom scanners, ASICs, or electronic components.
