GENERAL
X2
The active SAT IF splitter ASB 100 is a module of the head end system B - Line, which is conceived as a complete system for middle sized distribution networks.
SAT - IF OUT 1 EXT. LNC SUPPLY IN
The module distributes a SAT - IF signal without level loss to the four outputs.
OUT 2
The LNC remote supply voltage can be supplied internal or external via a "bypass".

FUNCTION DESCRIPTION A "bypass" is arranged at the SAT - IF input of the module to switch the LNC supply voltage to the input socket. With help of the jumper, the internal 12 V supply voltage of the module, or an external voltage, supplied over the output socket “OUT 1” (for example 13 / 15 / 17 V from a passive distributor PSB 100), can be selected. If the remote supply is active, a green LED next to the input socket is lit up. The remote supply can be deactivated. The electronic loss adjuster makes the adjustment of the optimal input level of the following processing units possible. With a directional coupler the input signal is uncoupled onto a test socket (-15 dB). The frequency response is compensated with a firm, internal equalizer. A two stage amplifier adjusts the splitter attenuation of the output four-way splitter. Additional information:

SECURITY AND OPERATING INSTRUCTIONS When assembling, starting-up and adjusting the modules, it is necessary to consider the system specific references in the instruction manual! The modules may only be installed and started up by authorized technical personnel! When assembling the modules into the receiving points, the adherence of the EMV regulations is to be secured! The assembly and wiring have to be done without voltage! All active modules may only be operated with the head end controller HCB 100 or bus extender BEB 100! The main voltage for all power supply units is 230 V, 50 Hz. With all work the defaults of the DIN EN 50083 have to be considered! Especially the safety relevant execution of the DIN EN 50083/1 is necessary!
