Hello All,
I am using LabVIEW 2012 to control Chroma 63600 Electronics Load through Ethernet. The whole system has worked for half of year and several weeks ago, it stopped working.
I have tried using NI MAX to send *IDN?\N to the Electronics, but the following returend string is innormal. I have replaced a new ethernet card but the problem is still there.
1: Write Operation (*IDN?\n)
Return Count: 6 bytes
2: Read Operation
Return Count: 11 bytes
\xFF\xFD\x03\xFF\xFB\x03\xFF\xFB\x01\r\n
3: Write Operation (*IDN?\n)
Return Count: 6 bytes
4: Read Operation
Return Count: 14 bytes
login: *IDN?\r\n
5: Write Operation (*IDN?\n)
Return Count: 6 bytes
6: Read Operation
Return Count: 12 bytes
password: \r\n
7: Write Operation (*IDN?\n)
Return Count: 6 bytes
8: Read Operation
Return Count: 17 bytes
Login incorrect\r\n
i have another Chroma Power supply and the IDN? returend string is:
1: Write Operation (*IDN?\n)
Return Count: 6 bytes
2: Read Operation
Return Count: 32 bytes
CHROMA,62006P-30-80,00286,03.00\n
Thank you for your help!
