i'm using tow PCI-6110 devices connected via RTSI and want to perform data acquisition from multiple channels synchronously on both boards.
question: how do i synchronize the scan clocks on both boards, using LabWindows/CVI?
my PROBLEM is that a noTransferinProgError of the slave device (upon DAQ_Check) occurs, and i suppose that the scan clocks are not synchronized properly -
or maybe the problem is something else??
details:
data acquisition is triggerd externally (voltage pulse into PFI0 of master device: "Select_Signal (iMaster, ND_IN_START_TRIGGER, ND_PFI_0, ND_LOW_TO_HIGH);"). the start trigger TRIG1 of the master device is routed to RTSI1: "Select_Signal (iMaster, ND_RTSI_1, ND_IN_STA
RT_TRIGGER, ND_LOW_TO_HIGH);" and is used by slave (set to external trigger): "Select_Signal (iSlave, ND_IN_START_TRIGGER, ND_RTSI_1, ND_LOW_TO_HIGH);". i tried to synchronize the scan clocks by "Select_Signal (iMaster, ND_RTSI_CLOCK, ND_BOARD_CLOCK, ND_DONT_CARE); Select_Signal (iSlave, ND_BOARD_CLOCK, ND_RTSI_CLOCK, ND_DONT_CARE);" but this didn't help.
merci,
kawi
