Remember to check the following:
- Wire Connection from PC to Supply as shown on pg 41 of the manual
- Configure the RS-232 Communication settings for both the PC and Supply as shown on pages 40-41 of the manual. Both the PC and the Supply must be the same.
- Using LabVIEW, load the proper VISA Configuration from step 2 then send (VISA Write) the string
*IDN?\n
where the \n is the newline character.
- Still within LabVIEW, receive (VISA Read) the response from the Supply. It should respond with a string that starts with the following:
ODA Technologies,EX-Series,...
Make sure to set the Read Buffer length to 200 in length.
- Now end the connection (VISA Close) by wiring this to the end.
- This string of commands will be used over and over for sending any other SCPI commands besides just *IDN?\n.
NOTE: An error will occur from the VISA Read when a command is sent that does not request a response from the Supply. To correct this, only run the VISA Read when the command string sent to the VISA Write contains a "?".
Good Luck.
