Page 15: Standalone
RWC2010M can be used while controlling it with a PC application software. Users can control it with users’ own designed software, remote commands, or can use RWC2010x_application.exe which controls through Ethernet or RS232. 2.3.1 Standalone For standalone operation, a file that can be played during booting must be downloaded in advance.
Page 16: Content File
Audio Analyzer : RWC2010M provides audio analyzer function. This measures the audio signal input to the 3.5pi stereo jack on the rear panel of RWC2010M. Since it is independent of the transmitter, it can be operated concurrently with the transmission. To use Audio Analyzer, you need to activate the function using PC software.
