Yokogawa UP550 RS-485 Communications

Wanted to get this info available for a search: Yokogawa UP550 RS-485 Communications

A terrific earlier post for the UP351 was available and it includes very helpful info for the UP550 model,

and a link for the Yokogawa Document "GREEN Series Communication Functions" IM 05G01B02-01E

slbLV,

I am not sure what you mean by having it "available for a search."

The link you posted does not lead to a valid page.

Probably this: http://forums.ni.com/t5/Instrument-Control-GPIB-Serial/Communication-Protocol-with-RS485-and-Yokogaw...

Since the old thread was obviously searchable, I don't understand the post.

Dennis_Knutson,

Thank you for the correction in the Link.

Last week I was searching for UP550 and the only item that displayed was the referenced Link,

and only because some else asked a question in the UP351 thread concerning the UP550.

My attempt with this new thread was to focus on the UP550 and show that it was very useful information.

Was that action (creating a new thread) NOT a good idea ??

Thanks

Since the old link did reference the UP550, I just didn't see the point but it's really no big deal.
