- Each output of the Power Supply Unit can power up to 4 modules
- The technical characteristics described are defi ned for a maximum ambient temperature of 45°C (113ºF). Forced ventilation is used for higher temperatures.
Inputs/Outputs/Connections description
The unit (Fig. 1) is provided with:
1. RF output + 2 CH TV (module A and module B)
2. Powering BUS connectors
3. Status LED
4. Control BUS connectors
5. Audio / video input signal connector (module A and module B)
6. Programmer / PC connector
Introduction
The TWIN unit features two A/V inputs (modules A and B) which generate
two independent output channels.
The A/V inputs for each module (A and B) are modulated according to the TV
standard in an IF of 38.9 MHz.
The modulated IF signal is converted to any channel or frequency between 46
and 862 MHz and then, once fi ltered, it is amplifi ed to achieve the specifi ed
output level.
The module confi guration can be done using the universal programmer
(Ref.7134) or the TSuite software for PC.
Possibility of local/remote control and monitoring (IP / GSM) for modules
thanks to the headend management unit (CDC) ref. 5559/555901.
