ChannelPlus H512 Quick Start Manual

The H512 single channel modulator creates a new channel to add to
existing television channels. The H512 creates this new channel from a
video signal it receives via a single CAT-5 cable connected to one of its

Default Setting for H512
When not using baseband connectors insert all jumpers, (W1, W2, W3 &
W4 are installed at factory).
Optional Settings
To use baseband connectors as outputs when H512 receives video from
Cat-5 video source, Insert W2, W3, & W4, Remove W1.
To use baseband connectors as inputs when using the H512 as a stand
alone modulator. Insert W1 and remove W2, W3 & W4.

Things To Watch For:
No picture ... 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 H512 and
camera or wall plate are wired properly.
Weak ChannelPlus UHF channel ... If the TV has a separate UHF input, be sure that it is
connected.
Herringbone interference on modulator channel (diagonal lines):
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.
Herringbone interference on many channels, including modulated channel (disappears
when you remove the CATV/antenna feed)
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.
Audio volume is low ... 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.
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. See the section on programming.

Programming the H512
Program the new channel using the Program
H512. 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
H512. However, if the cable services use HRC or the TV appears to search for the "created
channel", program the channel injector for HRC.
For HRC enter a 98. Reset to IRC by entering 99.
Entries 98 and 99 are for setting HRC or IRC only. They do not change the channel number.
CAT-5 Cable Length Limitations:
The length of the CAT-5 cable that runs between the H512 and the camera or wall plate is limited.
See the individual camera or wall plate manuals for these CAT-5 cable run limitations.

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.
Installation requirements:
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.
Federal Regulation 47CFR15.115(b)(1)(i).
2) If an antenna is used in the system, the modulated channel signal strength may not exceed -
51dBmV at the antenna input port. Federal Regulation 47CFR15.115(c)(4).
For the Installer:
Any system you design must comply with these regulations. As the installer, you are responsible.
The H512 has the necessary characteristics to comply with the above requirements as designed
without additional accessories.
