3. Insert the provided screws through the side holes in chassis and thread
into the tapped equipment rack holes.
4. Fasten the bottom screws first, then fasten top screws, tighten securely.
5. Slide power supply and equipment modules into chassis.
HEADEND/DISTRIBUTION INTERFACE
6. Connect power supply to all modules before supplying line power to the
PICO MACOM recommends connecting the headend components
in the following manner:
power supply.
7. Connect modules as described in the manual associated with module.
Each of the modulators, signal processors or strip amplifiers output
are connected to a combining network. Either a PHC-12G or a PHC-
24G headend combiner may be used to accomplish this purpose.
The PHC-12G or PHC-24G passive headend combiner consists of
two rows of directional couplers combined by a hybrid splitter. Normally,
the odd channels are combined on one row while even channels are
combined on the other row of directional couplers for maximum isola-
tion. The output of the combiners may be connected to the input of a
launch amplifier such as a CA-30RK550 or CA-30RK1000. The output
of the amplifier is connected to the main distribution line.
A 24 channel system hook-up is shown. (The same combining result
may be accomplished by using a single PHC-24G). The two
PHC-12G outputs are combined via a two-way splitter, which is con-
nected to a CA-30RK1000 launch amplifier. The input levels to the
combiner, whether from a modulator, signal processor or a strip ampli-
fier, must be at the same amplitude.
