Custom Wiring Example - National Instruments NI 6535 User Manual

Custom Wiring Example

© National Instruments Corporation
You can use different wiring schemes to connect the PFI channels in
multiple configurations. This section describes a burst handshaking
example using an NI 653x cable adapter to provide compatibility between
an NI 6533/6534 and an NI 6535/6536/6537 where the fixture is
configured to work with the NI 6533/6534. Without changing the fixture
setup, the adapter and software can be changed to maintain functionality.
The NI 653x cable adapter can be configured using 22- to 26-gauge wire as
shown in Figure 7.
