Are you certain that the communication port connecting to the instrument is connected properly?  There are several connection options on the VT 4002 device.  Did you set up the communications for 9600 baud with 8-N-1?  Are you sending the proper command?  Try sending:

$00I\r

If you get a string of about 85 numeric (including spaces and decimal points) characters with the last 15 all being 1's or 0's, then the instrument is responding properly.  See attached appendix page from the manual.  Also, make sure that the instrument address is 00.  It can be changed, but is set to 00 initially.

Thank You for replying. I have done it with RS232 ans I have attached zip file which have all images. I send $00I<CR> na $00I\r but no response. I am using a VIs which are attached here. If there is problem in VI kindly tell me how to correct it. In FWD zip file I have attached all snaps of chamber. I am stuck in this task for many weeks please provide help

Try using this slightly modified version of the serial write/read to communicate with your VT4002.

Please convert VI to 2012 or 2015 Labview format. I am not able to see it.

Here it is saved as LV 2012

Is there any mode which I have to set for geting reply from the chamber like auto, manual and edit mode?if yes please specify. I just cold start the system turn on the button anf run VI in order to get reply from the system,

Hi Zarrar ! Did you suceed to control your 4002 oven ? I'm at the same point, i think we need to connect first before sending information like "$00I<CR>" to get the information. But i don't know how to do it, can someone help us ?

[Zarrar]

Its Done!
