Note: This example program exports the sample clock from the device to be used by an external device.
INSTRUCTIONS:
1. Set the desired physical channels and samples per buffer.
2. Set the PCLK output terminal, frequency and pulse polarity.
3. Set the handshaking parameters: ready for transfer event active level and pause trigger polarity.
4. Make the appropriate I/O connections as explained below.
I/O CONNECTIONS OVERVIEW:
Connect the data lines of the ports you specified to the data lines of the external device.
Burst input handshaking involves three connections: ACK, REQ, and PCLK. The 653x and the external device share a clock signal over the PCLK line. The 653x asserts ACK if it is ready to input data. If the external device also asserts REQ indicating it has valid new data on the data lines, the 653x latches data on the rising edge of the PCLK signal.
If your port list is 0, 0:1, or 0:3 connect your signals to ACK1, REQ1, and PCLK1, otherwise connect them to ACK2, REQ2, and PCLK2.

Thanks for the CVI sample code
Next time, please make sure to exclude from
the zip file the .cdb and .exe files.
Indeed, they are unnecessary, since CVI will
recreate them anyway.
In addition this make the zip file big. FYI
without this 2 files the zip file is now
around 9kB on my hard disk :-)
