This device is designed to help define the way DiSEqC-switches to the working protocols 1.0 and 1.1 and the number of entrances to 4 – x. It feeds the unit from the source of constant tension 12 V. For monitoring of correct inputs diseka used LEDs, which, if correct diseka must times a second switch, with only one to shine lights at any time. Permanent luminescence or nesvechenie one of the LED will indicate the failure sign. Moreover, it is possible to reduce the amplitude of parcels 22 kHz to 300 mV to test our diseka in difficult circumstances, such as long feeder.
Power supply – 12 V, a maximum of 200 mA
The number of controlled ports – 4, with the help of embedded LEDs
Protocol support DiSEqC 1.0, DiSEqC 1.1 (Write Port Group Commands)
2 22kHz-tone levels – 650mV, 300mV
The frequency of issuing commands – 1 Hz, 2 Hz, switch ports in a circle
Light and sound transmission indication commands
Protection against short circuits (current limit) with light and audible warning
