0xBFFF001d and 0xBFFF0015 errors

[rodriferfe]

Nothing, it doesn't allow me to upload anything... One question, in MAX, in I/O settings I select enable termination character and as termination character /r and I apply changes but when I close the window the changes are not saved and it returns to the default settings, why?.

Finally I've made the typical block contruction with OPEN-WRITE-READ-CLOSE VISA but the same error ("timeout expired before operation...") appered. The thing is that when I introduced the bloque "bits at port" between WRITE and READ as it is showed in this link " http://digital.ni.com/public.nsf/allkb/874B379E24C0A0D686256FCF007A6EA0 " the error does not appear but nothing happens at all, neither the pump moves nor a repply I get. /1A6000R\r and /1ZR\r are the commands I am using.

Thanks a lot

In MAX, when you enable the termination character, it is for the read. You must enter the correct one in text box and it must be \r and not /r.

The use of the Bytes at Serial Port is not recommended.

Please try one of the simple report commands - the ones with the ? prefix.

I've tried the ?6 command and the query Q (  /1?6\r and /1Q\r repectively) but the same problem appears... If the sintax is fine I have no clue of what's wrong...

Thanks a lot

I don't know either. I would suggest trying a tool such as portmon from Microsoft to capture communication from the vendor's program and from MAX.

I couldn't used portmon but I've used "free device monitoring studio". When monitoring the port the command is written and the problem is the reading, it reads nothing. I've tried with other device and I am getting the same problem. In the sniffer program the read request appear in red and basicaaly says:

buffer size 0x0

status 0x00000102

Thanks a lot
