Is there a way to output a buffered pattern on port 0 and input on ports 1,2, and 3 of the 6534 card while using an external clock to vary scan rate using LabVIEW?

Question

I am using a 6713 board to clock my 6534 board and want to output from the buffer a patten continuously on port 0 and read from ports 1,2,and 3 at the same time and clock speed.

Hello;
Unfortunately, you can't combine a 24 bit group by bundling 3 ports in the same group. Valid group sizez are 8 bits, 16 bits and 32 bits only. To accomplish that task, you will need an extra 6534 board, then configure that board to do a 32bit pattern input acquisition, and discard the data from one of the four ports.
You can definitely synchronize both 6534s with the 6713 throug the RTSI bus. To synchronize all boards together, just route the AO Update clock from the 6713 board to one of the RTSI lines, and use two more instances of the Route.vi to route from that same RTSI line to the PCLK lines of the two 6534s.
Hope this helps.
