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 "select"
button to choose which modulator and 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.

Terminating jumpers (remove for hi-Z)
Option:
To connect the video and audio to a local monitor, use RCA type ‘Y’ adaptors and
remove the ’LOOP’ jumper for this channel.
The model 5435 has built in loop through connectors on the “A” channel, so it
does not require the use of a ‘Y’ adaptor.

Cable HRC and IRC considerations
Note
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. : This setting can be entered on any
modulator channel, A, B, C, or D, and affects all channel assignments for
that unit. Cable channels must either be IRC or HRC.
