handshaking or i/o ??

[studentin]

we have a system outputting digital data at 16 MHz, the high speed i/o card i'm using is the 6533 to input this data.
The data rate is too high to input with pattern i/o, thats why we are using the burst handshaking mode kind of in a tricky way by setting the REQ line to a constant high voltage all time. we are actually getting data but do you think this is a reliable operation manner??

Greetings,

Unfortunately, this configuration is not absolutely reliable. The NI 6533 can stop acquiring data and de-assert the ACK line at any time. Unless you monitor the ACK line, it is likely that you will lose data and not know about it. To perform pattern input at 16 MHz, you may want to consider the NI 655x or NI 6534.

Good luck with your application.
