* CDS Continuous Digital Streaming
The streaming option associated with the ASC300-70 series beacon receiver provides a continuous, two byte, data stream running at 9600 baud that contains twelve bits of signal strength level indication as well as lock or alarm condition of the unit. Other baud rates are available. A female DB9,interface connector on the rear of the unit is specifically dedicated for this option.
