In single-cable satellite reception systems, interferences are possible if individual subscribers or receivers block the trunk line by means of an 18 V constant signal. Due to these interferences, other subscribers are no longer able to communicate with the multi-switch or LNB.
In practice, it is also possible that incorrectly configured receivers use the user IDs of other subscribers. In this case, we are talking about interferences in the form of the so-called ping-pong effect, because two subscribers “fight“ for the same transponder.
The single-cable outlets of the RV 700-E series have a microcontroller that monitors signalling inside single-cable systems. In addition to signal voltages (14 V/18 V), audio signals (22 kHz) or DiSEqCTM signals are also analysed.
The antenna outlets turn off a permanent voltage of 18 V and, by means of a user ID check, ensure that only the enabled user band IDs are transmitted from the receiver to the multi-switch via the outlet.
The PROGRAMMING UNIT RVP 700 transmits the user band IDs which need to be enabled to the single-cable antenna outlet, thus ensuring that the subscribers in a single-cable antenna system do not interfere with each other.
Using the PROGRAMMING UNIT RVP 700, a specialist retailer or installer configures one or several defined user IDs in the single-cable antenna outlet during the installation of the antenna system. To do so, the specialist retailer or installer connects the programming device to the F-socket of the antenna outlet. By means of the TechniSat RVcontrol app, a connection to the PROGRAMMING UNIT is established, and the data for the configuration
of the antenna outlet is transmitted to the programming device.
