Has anyone encountered communication problems when using a Yokogawa MW100?

[NMAYO]

I am using a Yokogawa MW100 paperless data acquisition unit and have been getting repeated errors in the data string from the Yokogawa.  I am communicating with it using RS-232.  The problem seems to be that the string that the unit returns is missing some of the information in the string.  For instance the scientific notation portion of the number read on one of the channels. Or just simply returning a blank string.  I was wondering if anyone had a problem similar to this and if they were able to fix it?  Thanks for any help.  This has been a problem for me for a while and I have been trying a lot of things to defeat it.

NMAYO,

You mention that the MW100 is returning a blank string.  One thing to remember, if a framing error is detected while a byte of data is being received, VISA will replace that byte with the default error replacement character and generate a VISA error.  The default error replacement character is a null or blank character.  Can you verify if VISA is generating an error?  A bit more on framing errors  here.
