1.3 General Information
ETI (or MDI) files describe the characteristics of a signal suitable for transporting a full DAB
Ensemble (or DRM Multiplex), where the ETI comprises a number of subchannels and a formatted
Fast Information Channel (FIC) between a DAB Ensemble provider and a transmission network
provider, and the MDI comprises a number of streams and a formatted Service Description Channel
(SDC) between a DRM Multiplex provider and a transmission network provider. It means that if a
specific broadcasting station’s T-DMB/DAB (or DRM) signal is recorded as an ETI (or MDI) file, the
recorded file contains all the information about the station.
Using the RWC2010M’s ETI/MDI player function with these files, specific broadcasting stations’
T-DMB/DAB signals or DRM signals can be easily regenerated in labs. The RWC2010M also provides
analog functions as AM/FM transmission and audio analyzer. It also provides RDS functionality as a
way to play pre-encoded RDS files.
It can be operated stand-alone, and also can be controlled and played with the RWC2010x PC
application. The RWC2010x PC application provides various control and measurement functions such
as file handling, AM/FM setting, remote controlling and gathering audio measurement data from
RWC2010M. Audio measurement data includes SINAD, SNR, THD, waveform and spectrum.

2.2.3 Setup parameters
RWC2010M, a dongle type device, does not have any console key, so direct parameter setting through
the device is impossible. Even RF basic parameters such as frequency and power must be set through
the PC application. However, in case of standalone operation, the last setup values are saved and
recalled when booting, so it can be used repeatedly without setting parameters.
2.3 Operation
When booting, RWC2010M automatically operates in the last setting mode and setting conditions
and outputs RF transmission signals. We define a mode that works without a PC application as
standalone.
RedwoodComm Co., Ltd. 14/42

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. If there is no file, automatic play does not work, and no RF signal is output.
The file setting should be set by PC software, and the mode last used is automatically saved, and
when the mode is changed or terminated in the PC application, it is automatically saved.
2.3.2 Controlling with PC Software
RedwoodComm provides RWC2010x PC application program for RWC201B/C/M control. Users can
use RWC2010x to download content files, delete downloaded files, set play mode, and perform
tasks such as ETI/EMI play and FM-RDS/AM transmission. Also, if the Audio Analyzer option is
included, you can control the Audio Analyzer and save audio data using the application. In
addition, standalone mode of RWC2010M and related parameters can be set.
When RWC2010x PC software is connected to RWC2010M, functions such as Multi Control, DRM
MRR, RT editor provided for RWC2010B/C cannot be used.

2.3.3 Operation Mode
RWC2010M supports ETI/MDI player and FM-RDS/AM transmission mode. All transmission modes
operate one mode at a time.
Fig. Transmitter Mode Selection
●ETI Player: Plays ETI files. The ETI file must be saved in RWC2010M internal storage.
●MDI Player: Plays DMI files. The MDI file must be saved in RWC2010M internal storage.
RedwoodComm Co., Ltd. 15/42

●FM transmitter: Select Mode to generate tone or select WAV file to transmit as FM modulated
signal. In order to transmit the WAVE file, the wave file must be saved in the internal storage of
RWC2010M. At this time, the RDS signal can be simultaneously transmitted by selecting the RDS
file.
●AM Transmitter: Select Mode to generate tone or select WAV file to transmit AM modulated
signal. In order to transmit the WAVE file, the wave file must be saved in the internal storage of
RWC2010M.
●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.
Fig. The screen of the audio analyzer of the RWC2010x PC application
If the IP setting and connection is done successfully, there will be a “Connected” icon displayed
in the left bottom of screen. If there is no “Connected” icon, please try again step 1~5.
2.4 Content file
When RWC2010M operates as an ETI/MDI player or FM/AM transmitter, the necessary files (ETI,
MDI, RDS, WAV) depending on the mode are called content files.
The content files stored in the internal storage space of RWC2010M can be downloaded from the
RWC file server to the user's PC at any time using the RWC2010x application, and can also be
downloaded to the RWC2010M internal storage.
2.4.1 ETI, MDI, WAV files
ETI, MDI, and WAV files created or owned by the user can be downloaded to RWC2010M using the
RWC2010x PC application.
RedwoodComm Co., Ltd. 16/42

Please refer to chapter 2.4 to know how to download content files for detail.
2.4.2 RDS files
In the case of RDS files, due to compatibility issues, the user's own files cannot be used. The RDS
files provided by RedwoodComm can be used, or dumped ones using the RWC2100F sold by
RedwoodComm can be used.
