Using Recommended Signal Termination
• NI 6535/36/37 devices are software-compatible with existing
NI 6533/34 NI-DAQmx applications
• You can interface to existing NI 6533/34 fixtures and terminal blocks
with the NI 653x cable adapter
Connectivity Options
To meet connectivity requirements for high-speed digital applications,
you can use NI 6535/36/37 devices with a variety of accessories.
• A CB-2162 connector block
• NI 6535/36/37 devices are compatible with most NI 6533/34
timing modes – pattern I/O, handshaking, change detection, and burst
• A 50 Ω shielded flying lead cable
• A VHDCI high-density connector
High-Speed Data Streaming
• Generate and acquire larger digital waveforms with PCI Express
high-speed devices, using the ideal, low-cost NI 6535/36/37 devices
• Stream continuously at up to 200 MB/s of data
• Stream data from the host computer’s memory or high-end storage
solution such as NI RAID arrays and controllers
• Use for applications requiring high speeds and fast streaming
capabilities such as LCD testing, wireless protocols, ADC/DAC
interfacing, or digital pattern capture

Multidevice Synchronization
Figure 2. You can use NI 6535/36/37 devices with an NI 653x cable adapter to connect to
existing NI 6533/34 applications.
These products use the PXI trigger bus or RTSI bus to send and receive
clock and trigger signals to and from other NI 6535/36/37 devices in your
system. With these capabilities, you can create synchronized systems
with large numbers of digital I/O lines.
• In comparison to legacy digital I/O boards, NI 6535/36/37 devices
have improved signal quality. In Figure 3, the top eye diagram is from
an NI PXIe-6535 generating at 10 MHz. The bottom diagram shows an
NI PXI-6534 generating a 10 MHz signal using signal termination
recommended by NI.
