Controls and Connections
The ChannelPlus 5400 Series are digitally-tuned video modulators that convert any
baseband video and audio signal to a user-selected UHF, or Ultraband CATV. An
internal quartz crystal reference oscillator and PLL circuitry ensure drift-free
performance. The user selects the output frequency (channel) using the "program"
button to enter the number of the desired channel. Any TV connected to the output
via coax can receive the signals, when the TV is tuned to the proper channel.

Cable HRC and IRC considerations
Most cable services use IRC frequency assignments. This is the default for
the ChannelPlus
modulators. However, if the cable service
uses HRC or the TV appears to search for the "house channels," the
modulator can be reprogrammed to use HRC assignments by entering the
number “ 98”. Set to IRC by entering a “99”. Both of these settings are only
used for setting HRC/IRC.
