I m using LABVIEW 8.6 as my software base and PCI-6251 card with NI Elvis 1 board.I want to access analog and digital signals simulatneously.I was informed that for digital ouput the NI Elvis has to be configured in By-Pass mode.When in By-Pass mode anlaog signals cannot be accesed .I want to generate PWM Signals in which the reference signal that is to be compared with traingular wave is analog i/p generated from hardware ckt .And the PWm signals should be digital.So please tell me how to access analog and digital signals both simulatneosly through NI Elvis .
