I'm trying to connect to an Agilent 4284A LCR Meter. Until now I've been using Vee with Direct I/O commands and everything's been working OK. But I have noticed that I cannot communicate with the device in any other mater. I tried the Interactive I/O application, but it times out on every read (no mater how long a wait time I set), including the *IDN? read (which works fine when sent trough Direct I/O in Vee). I also tried the compiling and running the C idn.c sample program but it crashes on ipromptf . Any ideas on what to do?
Thank you for your time.
Thank you for your time.
Sometimes restarting the instrument by power-off then power on again might help
I would suggest to turn on IO Monitor come with Agilent IO Libraries Suite, compare the transaction message details for VEE and other application.
Hope this helps
