PLS help to check.

Many thanks!

Nice, thanks for sharing your solution!

I am somewhat surprised that could possibly find the old data but not record the new. Your Mango log files are at Mango/logs/ and the Mango log is ma.log. I have seen some people whose logs are in Mango/bin/logs/ on Windows.

The best way I found to do this was to create a second sheet and have Mango paste the data into that and then on the first sheet you simply link to the data on the second sheet.

See sample below. Highlight at least 2-3 rows and then in the formulas tab choose create from selection. These are now what you select in Mango. Format the columns before you upload the Excel file.

@terrypacker
I'm clear. I'm appreciated for your reply.

Hello Jared, Thanks for your reply.

@jackchang I know this was 2 years ago, but if you're still around could you point me to which RS232 to RS485 converter you used?
