I have a DC power supply, I want to read data and control it in mathematica.
i have already make the connection in labview see the follow picture.
and a few simple orders it can give a response. it's TCP/IP protocol.
now how can i do it in mathematica?
i know how to connect a RS232 device in mathematica 10,
the DeviceOpen order is useful in RS232(COM).
I see in other topics, they use JLink, i know nothing of it, it reports errors. see it below
this is for another device, it works
but when i change it for my device, and give a simple order,
same as the labview,"*IDN?\n",
no response, it's running for ever.

what's the problem?
Is there any other way without JLink?
