Communication Protocol with RS485 and Yokogawa UP351

[turkeyspdr]

This "\ display mode" was key for helping me to communicate with a UT550, thanks for throwing that out there!

And for the UT550, CR does come after ETX.

Also want to add my Thanks for the information.  I'm using a Legacy Yokogawa UP550.

The older communications info is not redily available at Yokogawa (via my search terms !! ),

but this NI discussion showed up in my search.

The clues provided and path for the Yokogawa Document

"GREEN Series Communication Functions"  IM 05G01B02-01E is a blessing.
