Digital tuner reset RTC-100
2Ïðèêà÷åíî(è)
The RTC-100 designed to be used in SMATV and
CATV head-end stations, where individual digital receivers are used as the source of signal path channel. Supervising of the correct tuner operating is executed by checking the audio signal, which is delivered by satellite digital collector, and then its reset in case of no signal received. The audio signal receiving procedure is divided into three stages. In the first - in the moment of audio signal loss the device is counting the break time. If the break is longer than 60 seconds the device resets the digital receiver by cutting the power supply and restarting the receiver. If there still is no audio signal, the device is counting next break period to 15 minutes and again resets the receiver. Continuing audio signal loss causes the time loss counting till 1 hour and resetting the receiver in one-hour course. If there is audio signal present after restarting receiver, the device acts as in the first stage. On special order the counting time can be programmed changed in T*****-TELMOR. |
