Hi,

Is there any way to control the PT104 under Linux? When I try to download software there only list Microsoft options. Already installed, running fine, and so on. But the objective is to integrate with the control system under Linux. Is possible to have a sdk? Perhaps send commands via serial port without fry the device?

Thanks

Hi unfortunately there are no linux drivers, however you There is no should be able to write commands directly to the port using the protocol described in the manual, under section 5.

Hi,

I'm back with this try, but block at the very beginning: I cannot read temperatures, for example from kermit.

From a windows software I can read the temperatures and record what is transmitted and received. Only setting one channel to minimize the text I read:

(...)

And after that seems the continuous reading.

But when I connect from kermit, or other serial line communication programs, I don't have an answer to the commands from the technical reference document.

Even the rarest thing I can see is that the first communication throw the windows software is a reception of "FF 55 AA 68 11". Neither I can see this if I send a 0x00 to the instrument.

How can I start talking with the instrument?

Thanks
