different timebase for different ports on 653x?

[hedgy]

Hello,

I am a relative novice at Labview,  I am using a 6534 and a 6533.  I output a digital waveform (8 bits wide) to port 0 or port 2.  With either board, if I use port0 and build the waveform with sampling rate of 1kHz, I get the appropriate square wave (period 500Hz) when looking at the LSB of port0.   If I do the same exact thing using port2, the square wave on the LSB is 1/8 of the sampling rate.

Can anybody tell me why? and how can be fixed? I ultimately need to use all ports with different waveforsm that need to be synchronized...

I attach the VI I used to do whT I described above.

Thanks,

Hello,

I apologize to the community..... the reason why I was seeing apparently different timebases on different ports of  653x is that I was probing the 3rd  bit of port2 , thinking it was the LSB.... that's the factor of 8....

Sorry!
