Hello,
Does anyone know any information on how to get IDN from MAP300 super-applications using syntax *IDN? <Slot #> passed via CMR.
Example, I have a mHROSA-A1 - MAP-200 Integrated Multi-Wavelength Wavemeter and High-Resolution Optical Spectrum Analyzer in slot 2 of my MAP 300 and I am using IVI Visa driver to connect to MAP 300, using VISA TCPIP. I can pass in the command "SYSTem:LAYout:PORT?\n" to get response "CMR\sMAP-300\s8100,1\sOPM\s8201,2\sHROSA\s8302,3\sVOA\s8203,4\
sVOA\s8204,5\sEDFA\s8205,6\sEDFA\s8206,7\sBBS\s8207,8\sBBS\s8208\n" and I can use the command "*IDN? 3\n" from the CMR to get the following response "JDSU,VOA, *, *" but when I try to same the command for "*IDN? 2\n", I get the error "
Write Operation (*IDN?\s2\n)
Error
VISA: (Hex 0xBFFF003E) Could not perform operation because of I/O error.".
For some reason, I am unable to connect to the cassette at slot 2 unless, I start one of the super-application (HROSA) from the MAP-300. Is there a way to get this information without physically selecting the super-application from the MAP-300 GUI?
