Hi,
I'm using a PXI-1042 chassis with PXI-8176 controller. I tried to synchronize two PXI-6031E multifunction I/O cards in LabVIEW 7.1 with the LabVIEW example "Multi-Device Synch-Shared Timebase-Cont Acquisition" but received the following error:
==================================================
Error -89125 occurred at DAQmx Start Task.vi
Possible reason(s):
No registered trigger lines could be found between the devices in the route.
If you have a PXI chassis, identify the chassis correctly in MAX, and make sure it has been configured properly. If you are using PCI devices, make sure they are connected with a RTSI cable and that the RTSI cable is registered in MAX. Otherwise, make sure t
here is an available trigger line on the trigger bus shared between the devices.
Source Device: PXI1Slot4
Destination Device: PXI1Slot7
Task Name: _unnamedTask<3>
==================================================
I already specified my chassis and controller type under MAX, and noticed that when I clicked on the "Chassis 1 (PXI-1042)", the information window list all PXI slot as "UNKNOWN/EMPTY" (a screen shot is attached). Maybe that's why LabVIEW cannot find a route between the cards? Also attached is the PXISYS.INI file on the PXI.
I also tried to route the link manually using the DAQmx Connect Terminals VI but got the same error when I tried to route the PXI_Trig0 between two cards.
Also some questions regarding DAQmx:
1. With the DAQmx Connect Terminals VI, is it true that we can no longer make routings to RTSI lines "manually" as in traditional DAQ Signal Routing VI?
2. Is it possible to route, say, a constant low or high to a RTSI line like we could with the
old traditional DAQ VI?
Software info:
MAX version 3.1.0.3021
LabVIEW version 7.1
P.S. Using traditional DAQ VIs is no longer feasible because I just added some cards that supports only DAQmx.
Thanks!
Dan
