5. Input circuit
In the PXU 848 IP, signals are directly fed to the input tuners. Due to the triple tuners, there are eight inputs each for
SAT and eight for terrestrial signals (DVB-T/T2 or DVB-C).
In the ‘factory settings’ condition, there is a 12 VDC
voltage for LNB supply on SAT input tuners 1, 2, 5 and 6. This can be switched by corresponding jumpers J1, J2, J4
and J5. On tuners 4 and 8, a 12 V supply voltage for the terrestrial range can be activated by inserting the
corresponding jumpers J3 and J6. The operating states are indicated by external LEDs.
6. Mounting
The IP Streamer must be installed in a well-ventilated room. The ambient temperature must not exceed 45 °C. It
must be ensured that air can circulate freely through the ventilation holes, this applies especially with horizontal 19"
mounting. In order to free air circulation, a minimum distance of at least 15 cm from the ventilation holes is required.
The mains plug must be pulled out for installation or when working on the wiring.
