Hi Shibaev,
Thanks for posting on the NI forums.
I have taken a look into this one. From what is documented in the Traditional NI-DAQ manual, and the DAQ help file, the trigger lines for PXI devices are referred to as RTSI lines. For PCI devices there is an optional connector for a RTSI cable to provide shared triggers in a desktop PC. With PXI these lines are built into the PXI chassis. Although PXI and PCI are different form factors for DAQ devices, the (Traditional) NI-DAQ driver refers to either RTSI lines or PXI lines as simply 'RTSI'.
To route your clocks/triggers accross these lines you should use the string "RTSI X", where X is the line number you wish to use (X = {0,1,...,6,7}). Take a look at the attached .jpg for a list of possible signal route connections (this was extracted from the NI-DAQ help file).
I hope this helps!
