Hi !
I have some troubles communicating with my Vötsch VCL 7010 climatic chamber.
I would like to control it via TCP/IP protocol in LabView, and here is the problem : I am sendind what seems to be the right strings of command, the chamber response is 0<CR> as it should be, and if I ask for a setpoint of 70°C I have a setpoint of 70°C.
But the oven doesn't want to start.
Here is exactly the string I send :
$01E 0050.0 0000.0 0000.0 0000.0 0000.0 0000.0 01000000000000000000000000000000 <CR>
Does anybody have any ideas on the subject, or is there anyone who is using this type of chamber and is able to communicate with it ?
Another odd thing : all my programs worked with the VT 4004, and the protocol is apparently the same...
Here is the datasheet :

No no, I am using the \r

What about the chambers bus id ? Are you sure that 1 is right ?

Could it be that some reason (not a communication problem) doesn't allow the chamber to execute the start command ?

A comparison with the Set nominal values for parameters command (interface protocol, page 9-12) shows that yours is incomplete :
$01E 0023.0 0050.0 0080.0 0000.0 0000.0 0000.0 0000.0 011 01010101010101010101010101010 <CR> ---> interface protocol
$01E 0050.0 0000.0 0000.0 0000.0 0000.0 0000.0 01000000000000000000000000000000 <CR> ---> your command

I tried it already, and it's still not working 😞

Hi,
did you find a way to make it work. I encounter the same problem right now 😉

Hi !
I finaly decided to use both protocols. According to the manufacturer, it may be because of the interface on this chamber (which is a bit different than the one I had on the VT 4004).
So I mainly use the ASCII-2 to read the values, stop the chamber, but I use ASCII-1 for setpoints, since the ASCII-2 can set the values but does not launch the oven...
I have a small library that works welle on my chamber, do you want me to give it to you ?
