ICE-HE Ethernet Head End
RF Coax and iCC-Net Operation
1.
Connect an RF coax feed from RF Out to the system’s RF combiner, mixing the iCC-Net Out signal
with the other CATV channels. The iCC-Net Out channel operates at 74.7 MHz, in between cable
channels 4 and 5.
2.
When combining the RF output with QMOD modulators, add the included 20 dB attenuator – this
will lower the output to match the QMOD’s 29 dB. 10 dB attenuators are included for use in 45 dB
systems.
3.
Using an RF signal level meter, use the front panel RF Out adjustment counterclockwise to match
the RF Out signal to the other CATV sources. Limit RF Out adjustment to -10 dB, using
attenuators to achieve a lower signal strength.
4.
Add a Sub-CATV Diplexer after the CATV amplifier.
5.
Connect the Sub-Channel output of the Diplexer to the HE RF In connection
