Resetting Device RTC-100 (for DVB-SAT-Receivers)
General view of the device

RTC-100 is a device used for resetting individual DVB-Sat-Receiver in head stations equipped with receivers of that kind. The device works on principle that the lack of audio signal for a defined period of time results in momentary switching off the receiver's power. This way, being employed in SMATV/CATV head stations, the item monitors the operational state of individual receiver, and restarts it when a hang up occurs. Therefore, the station becomes self-reliant, not depending on human-operator service. In practice, the hang up is the most common failure within head stations using separate digital receivers as the source of channel signals.
The only effective way to restore the operation of a receiver, now then the channel, is the restart, forced by the dedicated device.
RTC-100 efficaciously controls receiver - it detects hang ups and reconditions normal work.
Operating method
The process of control a receiver is based on monitoring its audio signal. The procedure is divided into three stages: 1.- if a fading occurs, the device counts its time, and after 60 seconds of the lack of signal resets the receiver, switching it off and on; 2.- when any audio signal has not further emerged, the device waits for 15 minutes, until it resets the receiver again; 3.- in a case of subsequent, continuous lack of signal the receiver is being restarted every hour has passed. Of course, when a signal is detected, the device undergoes to the first stage. The standard periods of time can be changed to special order by the producer (TELKOM-TELMOR).
Construction
The RTC-100 unit is similar to extension cord, having mains plug and ~230V outlet to power a digital receiver, and two RCA sockets (cinches) to connect to audio output of the receiver and audio input of a modulator. Green-lighting LED is signaling that the device is in working order.
Operating remarks
After the connections have been properly made, the device works autonomously, not demanding any service. The maximum output power rate is limited to 50W (the maximum power consumption of controlled receiver).
Modes of operation:
1. If a fading occurs, the device counts its time, and after 60 seconds of the lack of signal resets the receiver switching it off and on.
2. When any audio signal does not further emerge, the device waits for 15 minutes, until it resets the receiver again.
3. In a case of subsequent, continuous lack of signal the receiver is being restarted every hour has passed.
