how do you set the gating mode on a 6025E

[JD2]

I am using traditional NI DAQ functions/Visual C++ and am trying to set the gating mode on counter 1.

When I try to set the gate mode it displays reports the following error;

-10403 The specified device does not support the requested action (the driver recognizes the device, but the

action is inappropriate for the device)

I have connfigured counter 0 to generate a pulse and have wired counter 0's output to counter 1 gate

input. While the gate is high on counter 1 I want to generate a pulse train

Hello,

Try using the following command:

GPCTR_Change_Parameter(iDevice, ulGpctrNum, ND_GATE, ND_OTHER_GPCTR_OUTPUT). 

The "ND_OTHER_GPCTR_OUTPUT" parameter internally routes the counter 0 output to the gate of counter 1.

Try running the attached code which will generate a square wave on counter 1 that is gated by the output of counter 0.  To see the gating, set up a slow (about 0.5 Hz) pulse wave generation on counter 0 in MAX.

I hope this helps.  Please let me know if you have any further questions.
