The H511 channel injector
creates a new channel to add to existing television channels.
The H511 is designed to work with an existing installation without the need to add additional hardware
such as a coax panel or additional coax wiring to the video source. The
H511 creates this new channel from a video signal it receives via a
single CAT-5 cable connected to one of its companion
products such as the H721 camera or H110 wall plate.
Two models are available:
The
has the isolation required by the FCC
for a system with an antenna.
The
has a 5-42MHz reverse channel to
support bidirectional cable systems (cable modems,
pay-per-view and interactive cable).

Things To Watch For:
Herringbone interference on modulator channel (diagonal lines):
Herringbone interference on many channels, including modulated channel (disappears when
you remove the CATV/antenna feed)
You may have chosen a
channel number that is not completely vacant. Distant UHF stations may not be 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 modulator channel to another
number. You may have to add a low pass filter to remove the cable company noise. If the filter does
not work, try adding a DC-block to remove common mode interference.
: The RF amplifier can be overloaded by abnormally strong
signals. Often, you can cure the problem with a simple attenuator. Use a variable attenuator and try to
find a signal level where the interference just disappears. Sometimes, the problem is one station is far
stronger than the rest. In this case, attenuating all of the signals with a simple attenuator may cause
the desired stations to be weak (snowy). You must reduce the strength of the only offending station. A
common FM trap will help if the problem is a nearby FM tower. If the problem is a nearby TV station,
often the station management can provide suitable filters.

… 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. Also ... Make sure the H511 and camera or
wall plate are wired properly - CAT-5 colors must match connector colors.
… 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.
… 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. See the section on programming.

DECLARATION OF CONFORMITY
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE
FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2)
THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY
CAUSE UNDESIRED OPERATION.
FCC classifies this product under part 15 of its rules as a “television interface device”.
Systems designed using television interface devices have the following legal requirements:
1) The modulated channel signal strength may not exceed 15.56dBmV at any television.
2) If an antenna is used in the system, the modulated channel signal strength may not exceed -51dBmV at the
antenna input port.
Any system you design must comply with these regulations. As the installer, you are responsible. The H511 has
the necessary characteristics to comply with the above requirements as designed without additional accessories.
The H511HHR is suitable for use with an antenna or with CATV systems.
The H511BID is suitable for use with CATV systems only.
Installation requirements:
For the Installer:
Federal Regulation 47CFR15.115(b)(1)(i).
Federal Regulation 47CFR15.115(c)(4).

Program the new channel using the
push button to enter channel digits into the
H511. This new channel should be an unused channel. It should have no interference or
trace of a picture - just “snow”. There must also be one unused channel both above and
below the selected channel to avoid interference. Below is a simple step by step example
of how to program a channel - cable channel

Cable HRC and IRC considerations:
Most cable services use standard or IRC frequency assignments. This is the default for the
H511. However, if the cable services use HRC or the TV appears to search for the “created
channel”, program the channel injector for HRC.
Entries 98 and 99 are for setting HRC or IRC only. They do not change the channel number.
For HRC enter a 98. Reset to IRC by entering 99.
CAT-5 Cable Length Limitations:
The length of the CAT-5 cable that runs between the H511 and the camera or wall plate is
limited. See the individual camera or wall plate manuals for these CAT-5 cable run limitations.
Specifications: typical @ 25 C ± 5 C

The color bar has two rows:
-Use top row for wiring with CAT-5
-Use bottom row for quad wire
The H511 was designed to work with CAT-5 wiring. Although the system will function with quad
wire, CAT-5 delivers the highest quality picture. CAT-5 allows the use of an automatic line length
sensor and picture compensator. Quad wire does not take advantage of this enhancement.
