SGA power supply NI Max

[Shawn19]

Hi All,

im looking for some help on how to get NI MAX (NI VISA) to read the a SGA power supply using a RS232 cable, NI max reads the com but when i try to communicate to the SGA power supply i get :

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed. when i try to communicate using the *IDN? command.

i can talk to using the hyperterminal software so i now my cable works, i installed the required drives and NI VISA but nothing.

Thanks!

If a terminal emulator works it's most likely that you have not properly configured the VISA session settings correctly.   It is common for DTE to expect a <CR LF> to know when a command is complete before processing the command and responding.

I don't know what an SGA is but I bet you a Kudos that the manual for the device tells you how to format a command properly.
