Counter/Timer

[afsfqr4aw3esf3]

I am trying to route counter outputs to the RTSI connector in DAQmx via VB.NET. My routing code is simple:

            DaqSystem.Local.ConnectTerminals("/Dev1/Ctr0InternalOutput", "/Dev1/RTSI0")

I do this before starting the task. I've also tried replacing Ctr0InternalOutput with PFI36; I get the same result. That is:

1. No error message. Presumably then the route is valid and is made.

2. I get 5VDC on all the RTSI pins. This is true for all the RTSI lines (0 through 6 and OSC) and happens the minute the computer is powered up.

I verified my cable is correct (I took a ribbon cable and wired it to BNC connectors according to the pinouts at http://digital.ni.com/public.nsf/allkb/392DEFA8A72CA693862572E300651A9F).

What am I not understanding here?

Wow. Nobody has any ideas?

Good morning,

Have you verified the default settings? Maybe they're on true when you start the computer.

The following code does nothing in my case, even after adding an RTSI cable in MAX and "connecting" the PCI6602 to it:

DaqSystem.Local.ConnectTerminals("/Dev1/Ctr0InternalOutput", "/Dev1/RTSI0")

 Instead, I used the second way of routing signals:

TheTask.ExportSignals.CounterOutputEventOutputTerminal = "/Dev1/RTSI0"

 This works like a charm. Go figure why the other method doesn't do squat; it isn't the first time I've had this type of problem.
