National Instruments PXI-6533 / PXI-6534 Series, 32-Bit Digital I/O Interface
Features

• 32 Digital I/O Lines (5 V TTL/CMOS)
• Pattern I/O up to 13.3 MB/s; Handshaked I/O up to 77.8 MB/s
• User-Defined Power-Up State

The National Instruments PXI-653x Series is a high-speed, 32-bit, parallel digital I/O interface. It incorporates the National Instruments DAQ-DIO ASIC, a 32-bit general-purpose digital I/O interface specifically designed to deliver high performance on plug-in digital I/O modules. The NI PXI-6533 performs single-point I/O, pattern I/O, and high-speed data transfer using a wide range of handshaking protocols at speeds up to 76 MB/s. You can operate the 32 lines as individually configurable single-line I/O, or as 8, 16, or 32-bit ports for pattern I/O and handshaking.
