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.

Things to watch for:
LEDs blink
Herringbone interference on ChannelPlus channel (diagonal lines)
Herringbone interference on many channels (disappears when you
remove the modulator)
... You need to have one unused channel space between
channels. The display will blink if you have made an ‘illegal’ choice. See
the section on programming.
...
You may have chosen a channel number that is not completely vacant.
Distant UHF stations may be un-watchable, but will cause interference if
you try to create a new channel at the same frequency. Also, cable
companies often have extra signals where there should be none. Try
moving the ChannelPlus channel to another number. You may have to add
a low pass filter to remove cable company noise.
… The high output of the ChannelPlus modulator
can overdrive many RF amplifiers. Reduce the RF output using an
attenuator. (ChannelPlus coax panels are designed to take the full output
of these modulators.)
No color on ChannelPlus channels … You may have chosen the
incorrect cable standard. Not all televisions can accommodate the
1.25MHz frequency difference between the H and I cable standards.
No picture
Weak ChannelPlus UHF channel
Audio volume is low
… Verify that the video source is on and is producing a video
signal. Check that the TV and the modulator are tuned to the same channel.
For example, if the modulator is broadcasting on UHF channel 16, make
sure the TV is on UHF 16 rather than CATV 16. UHF 16 and CATV 16 are at
different frequencies.
… If the TV has a separate UHF input,
be sure that it is connected.
… The left and right audio inputs are combined for
monaural. For proper audio level, both right and left inputs must be used. If
you have a mono source, connect it to both right and left inputs using an
RCA ‘Y’ connector.

If an error has occurred or an incorrect channel is
entered, the LED will flash quickly for a second and
return to the previous settings.
If two adjacent channels are selected, the unit will
accept the entry but will blink the LEDs of channels
that are too close. If this happens, re-program one
of the channels to move it away from the other.
