Norman,

Learn to write a single commands and get back a valid replies first, before
you try to develop an app to continuously communicate with the instrument.
Once you get the command set down, you can plug them into your state
machine.
Attached is a VI about ASCII to HEX and Carriage Returns.

Use a string control or string constant in
- "'\' codes display"
input control code with \r for CR, \n for newline,
\XX for a HEX value representation (check help for more possibilites)
- "Hex Display"
input hex values directly

Or create a byte array with needed values and use the "Byte array to
string" function

Thank you guys, at this point I am able to send my command to device and receive my data per single data command, but eventually I would send a different command to continously get data. At this point I have few questions, first my data printed out looks like this on Hyperterminal. at the prompt after it says either power on or reconnect , i enter my command ss/r

! RECONNECT
!
329-12:18:51 *01 RANGE"F *02 RANGE ''F

Above is an example. Does labview cares about the spacing in between the bytes because they are different between the Ranges. It says RANGE because I do not have any themal couple connected right now otherwise its going to be 0070."F for example. I need to save this also in Excel. I need to parse this data, can you guys help me on th
is. Thanks

"I'm having the most odd problem. I've drawn up my 1D array of U8, convert it to string using the U8-2-string converter and send it, but my device does not respond.

So I tap the line with an Oscope and I see that only some of the numbers are being sent out correctly. I send out a 32, it replies with a 32 (correct!). I send out a 30, it replies with a 34, 36 combination. Btw these are all hex values. I've checked and double checked that I'm sending out a hex 30. Anyway it started doing the same for the 32. What is happening??? I tell it to send two hex number, it sends four!!??!?"
