Can I Use Multiple External Clocks With My NI 6533/6534 Device?Hardware: Digital I/O (DIO)>>High-Speed>>PCI-6534, Digital I/O (DIO)>>High-Speed>>PCI-6533, Digital I/O (DIO)>>High-Speed>>PXI-6533, Digital I/O (DIO)>>High-Speed>>PXI-6534
Problem: I am using a NI 6533/6534 high-speed digital card to perform pattern I/O. Is it possible to use multiple external clocks to acquire or output digital data on different ports? Solution: Yes, you can use two different external clocks when performing pattern I/O on different ports of your NI 6533/6534 device. When performing pattern I/O, there are two control lines, REQ1 and REQ2, that are used to carry timing pulses either to or from a peripheral device. You can wire two different external clock signals to each of these two control lines. However, in LabVIEW, each REQ line is used to control specific ports, depending on whether you configure two 8-bit ports, two 16-bit port, or one 32-bit port? For more information about how to configure the handshaking lines of the 6533/6534 , refer to the link below.
