testing, pattern generation, memory testing,
and logic vector capture. This family features
maximum clock rates of 10, 25, or 50 MHz; selectable voltage levels
compatible with 2.5, 3.3, and 5 V TTL logic; and individually configured
pins for input or output. With both synchronous and asynchronous timing
modes, handshaking, and a software API designed around the NI-DAQmx
driver, NI 6535/36/37 devices have the flexibility to meet the requirements
of semiconductor, consumer electronics, and communications applications.
Applications
Digital Interfacing
• Use NI 6535/36/37 devices to interface digital systems and devices
directly with PC-based applications
• Control, communicate with, or send data to a digital device or system
• Analyze and record digital data
• Perform bidirectional communications with handshaking
Timing Modes
• Pattern I/O or sample clock (synchronous) – transfer
patterns using an internal or external clock signal
• Burst handshaking (synchronous) – handshake an NI 6535,
NI 6536, or NI 6537 device and the peripheral device during
synchronous transfer to maximize the transfer rate
• Handshaking I/O (asynchronous) – transfer patterns when both the
NI 6535, NI 6536, or NI 6537 device and the peripheral device are ready
• On-demand (unstrobed or static I/O) – acquire or generate
data through software-timed commands
• Change detection – acquire data whenever a change
occurs on one or more digital lines
