The PCI-DDA series family consists of three models with either 2, 4, or 8 output channels and 48 bits of digital I/O. The PCI-DDA series analog output channels may be updated independently or simultaneously. The PCI-DDA series is completely plug-and-play. There are no switches, jumpers or potentiometers on the board. All board addresses, interrupt channels etc. are set by your computer’s plug-and-play software.
