Experimental Physics and
Industrial Control System

Hi,

I am trying to use StreamDevice on debian system to control device, the device is universal frequency counter/timer.

When I execute the st.cmd file,it shows no error, but when I type caget, it shows pv name not found:

The description of the command of *IDN？ is in the attachment.

I don't know what's wrong, how can I solve this problem?

Thanks,
