Hello,
I control GPIB instruments from a Linux box via GPIB-232CT-A. I don't use any NI drivers, simply send low-level GPIB exchange commands from a dedicated program written in C. For example, in order to send *IDN?\n to device at GPIB address 15 I would write two strings to the GPIB-232CT-A (via the serial port of the Linux box):
wrt #6 15\r\n
*IDN?\n\n
The old GPIB-232CT-A boxes are slowly dying, and NI does not seem to sell them any more, so my question is: will these commands still work with the newer GPIB-RS232?
The old GPIB-232CT-A is very well documented here: http://www.ni.com/pdf/manuals/370898a.pdf.
My second question is: is there a similar document for the newer GPIB-RS232?
Thank you!
