Serial read byte order changing

[Wayne.C]

DPac,

How often does your application need a new value?  Are you trying to log data at 100Hz or are you updating a front panel indicator every half second?

Hi DPac,

your device is sending 6 bytes per message. You're reading 1024 bytes from a full buffer, that is 170 messages and 4 bytes of a  message: atleast 2 bytes of a message are left in the buffer, thus giving the warning... Simple math, eh?

No, you don't need another VISA-Read. Simply do your reads and collect the read data. Then split the data as is given in your manual: data is synced by MSB set on first byte of message. This was mentioned earlier, you really should listen to what we're telling you...

Edited: See attachment for a rough sketch!

Cheers for your reply guys. I'll try that!
