Hi,
I am trying to communicate with an old Sorensen DCS power supply (DCS100-12) via RS232. It has the M9 option and the manual is attached. I am using a RJ11 to DB9 cable as mentioned in the section 2.4.
Before going to a Labview VI, I am first trying to communicate using the VISA Test Panel. I am using the following parameters as mentioned in the manual :
Baud rate : 19200
Data Bits : 8
Stop Bits : 1
Parity : None
If I start the power supply and query "*IDN?\r\n" I get both the answer and a timeout error (see image below). The next query will always timeout (even *IDN? ).
I have tried a lot of different setting with no success. In the other hand I tried to use a GPIB to USB adapter from another device and it works fine.
Questions :
- Any ideas why the RS232 communication always timeout ?
- Why it give me a good answer only for the first query ?
