G interpretation

[Amon]

I have problem in writting the command in Intrument I/O Assistant of
LabView7.1 to communicate with my instrument.

I'm building a instrument driver for temperature controller of
Cole-Parmer,Model#89000-10.

The communication specification from manufacturer describes how to input
command string via ASCII, for example, T1UC, where is the
start of the text, is the carriage return, and T1UC is the command.

The problem is that how to convert into your backslash codes.

I know that is the termination character, which stands for \r in
Instrument I/O Assistant.

I want to know how to enter the exact command for this particular
instrument.
For instance, how to write a command of T1UC in your Instrument
I/O Assistant??

Sincerely,

It should be simply a matter of selecting a Write step in the assistant, entering T1UC as the command, and then picking the termination character. If this doesn't work, it could be any number of things. You could have a wrong cable or the serial port comm settings are wrong (baud, parity, etc.). I always recomend that people first get things working in a terminal emulation program like Hyperterminal before trying to write their own program. If you can get that to work, then more than half the battle is over.

If you just need to convert the command into "\" display, you can simply right click on the write buffer(Front panel)or the write string box(Block Diagram) and select ""\" Codes Display" option then type in the normal ASCII codes, it will automatically convert it to the backslash format.

Thank you Tong,
I already got the signal.
