The Radyne/ComStream audio codec/multiplexers are the market's most efficient, flexible, and compact digital audio encoder. The COMSTREAM DAC [Digital Audio Codec] devices (i.e., DAC 400 and the DAC700) accept analogue or digital audio input, then use ISO/MPEG Layer II compression to digitally encode the audio, reducing your recurring transmission costs and deliver audio at CD quality.
Radyne/ComStream digital audio networks are in use in more than 50 countries, sending audio information to customers of such diverse businesses as radio networks, including multiple channels for different languages, automated commercial radio distribution networks, Interactive audio information ("audiotex" networks), and in-store audio networks for retailers with regional advertising.
The COMSTREAM DAC devices can be built into a complete digital audio satellite uplink by adding a Radyne ComStream CM701 satellite modem, an RF transmitter, and an antenna. Moreover, it can also be set up as a full-duplex codec for point-to-point transmission using a DAC700 at each end of the link. Audio and data can be transmitted and controlled in both directions simultaneously.
Comstream DAC resource editor - User
Once the device has been set, it is required to set the user(s) that will be allowed to use the device the following parameters will be necessary:
•User: Set the user(s) that will be allowed to control the device,
•ID number: It's the identification number of the Etere PC of the selected user.
•PC name: It's the description of the Etere PC of the selected user.
•Function: Indicate the Etere function to be used (e.g., automation, split).
•COM n. - Set the number of the PC's COM port where the device is connected.
•COM Configuration - The COM port is configured with the following parameters (default device's parameters):
✓Baud: 9600
✓Parity: N
✓Stop bits: 1
✓Data bits: 8
•422: Set data referring to 422 only in the particular case of a centralized router, also allowing serial ports' commutation:
✓Device (out) - Set the number of the device to activate when the resource gets opened ("-1" = not managed).
✓Controller (in) - Set the number of the controller to activate when the resource gets opened ("-1" = not managed).
