Hello.
I have a Votsch VT 7004 which communicate in RS232 with my PC.
I want to change the heating rate of the Votsch. Are they a commend to do this ? And i want know how command " gradient up speed temp " works ?

See page 6 of this document for the command register. Not sure what the units are in, maybe degrees C per minute?

Thank you for your answer.
I have read my command register but when i launch my command the Error indicator of the Votsch lights in red. There's the " error 0 " messages. I checked my character string and he is good. I want to know why there's this message ?

Can you poll the chamber for the current setting of the parameter?
I must admit I am not familiar with this chamber.

I can communicate with my Votsch because i can choose the temperature i want and the four works. Only this gradient don't work.
I tested with your code and the error is always here. In my doc of my Votsch, this is not a code like this but it doesn't work too.

Is there a possibility to controll a Votsch using USB or Ethernet (no RS232 available)? Thanks!

Did you program VT7004 using just the Ethernet port alone? I have same situation. Out chamber doesnt have the RS232 or 485 options. Can you please help? Can you share the labview programs if yo u had them working?
Appreiate help.

Hello ,
Can you please tell me, if you have managed to communicate with the climate chamber via USB?

Do you have a chamber with USB adapter? If yes, what happens, if you connect it over USB to your PC? Does it load Drivers? Does it create a (virtual) COM Port? If yes, then you are able to communicate over COM Port.
Try any COM Terminal (e.g. hterm)
1. open corresponding port with 9600,8,N,1
2. send "$01I<CR>" to the com port (<CR> is carriage return and is 0x13, try also $00I<CR>
3. see what happens
If the chamber does not answer, then it probably has wrong protocol type set.
These protocol types are possible:
1. ASCII-1
2. ASCII-2
3. TSI
Look into the protocol description of ASCII-1 and try to request data in ASCII-1 format.
Do/did you have success?

I was able to communicate with the chamber via ethernet. I had wrong port number. So it was not labview error, it was me entering wrong parameters. It works fine now.
