Thanks for purchasing the 1T-CT-610 Series HDMI Extender product from TV One. The
individual components of this series of HDMI to CAT.6 Extenders consist of the 1T-CT611 Transmitter, the 1T-CT-612 Receiver and the 1T-CT-613 Repeater which
constitutes a system used to transmit deep color (12 bits) V1.3 HDMI or DVI-D signals
at resolutions up to 1920x1200 and 1080p, plus transmission of embedded lossless
audio, over Cat.5e or Cat.6 cables. The 1T-CT-611-612 can achieve signal distribution
distances of up to 45 meters (150 feet) for 1080p/8 bit signals and 15 meters (50 feet)
for 1080p/12 bit signals. This distance can be extended a like amount with the use of
the 1T-CT-613 Repeater. For normal operation, two Cat.6 cables are required, one for
the main signal and one for the HDCP/DDC signal. The transmit and receive products
also feature the unique TV One-task locking power connectors to enhance overall
system mechanical security.

Before attempting to use this unit, please check the packaging and make certain the
following items are contained in the shipping carton:
1x Repeater, Transmitter or Receiver unit
1x Power Adapter (Except 1T-CT-613)
1x Operations Manual
Note: Please retain the original packing material should the need ever arise to return
the unit. If you find any items are missing, contact your reseller or TV One immediately.
Have the Model and Serial Number and Invoice available for reference when you call.
Please study the panel drawings below and become familiar with the signal input,
outputs, power requirements/inputs plus any controls present. Note: The resolution
capability of the remotely located display devices must be capable of displaying the
output of the source device. Before connecting the CAT.6 extender system, verify that
the display device on the receiving end can support the output resolution and signal
format by connecting it directly to the source device.
Cat.5e/6 Cable Notes
Pins and pairing. Make sure the CAT5e/6 cable pin assignments are standard. The
correct pairing is straight through, pin-to-pin, with pairing as follows.
Twist density. UTP cable pairs have different twist densities (twist pitches). There are
two pairs with high density twist and two pairs with low density. Colors vary by
manufacturer. Twist densities can be seen by stripping off about 10 cm (4’) of insulation
and visually inspecting. Pairs 1-2 and 7-8 should be assigned to high density twists.
Failure to assign correct twist densities can result in image jitter. The ABCD picture
shows typical UTP cable, with pairs A and C showing a high pitch twist (assigned to pin
pairs 1-2 & 7- 8), and B and D with low pitch twist (assigned to pin pairs 3-6 & 4-5).
1T-CT-611 Transmitter
Connect the HDMI source device’s output to the HDMI IN connector of the 1T-CT-611
Transmitter, using an appropriate HDMI cable of no more than 15 meters (45’) in length.
1. Connect a Cat.5e or Cat.6 cable to the Video output connector of the Transmitter.
Connect a second Cat.5e or Cat.6 cable to the DDC output of the Transmitter. Mark
the cables at both ends so that you do not inadvertently swap them. Defer
connecting the AC adapter until the Cat.5/Cat.6 cables are connected to both the
Transmitter and the Receiver.
1T-CT-612 Receiver
1. At the remote location, connect the appropriate Cat.5e or Cat.6 cables to the
Video input and DDC Input connectors of the Receiver. Do not interchange the
cables. The Video cable must be connected to the video inputs and outputs in
both the Transmitter and the Receiver products and the DDC cable must likewise
be connected to the DDC inputs and outputs on the devices.*
2. Connect the HDMI connector of the Receiver to the HDMI input of the remote
display or other device, using an appropriate cable no more than 15 meters (45’)
in length.
3. Connect the supplied AC adapters first to the Transmitter and Receiver and then
to the AC sockets.
4. Lastly, turn on the source device and remote display. The source signal should
now appear on the remotely located display. If not, consult the Troubleshooting
section of this manual.
* Note that when a 1T-CT-613 Repeater is being used in the Cat.5e/Cat.6 cable path,
you must also make certain to connect the Video and DDC cables properly. Marking all
cables at both ends so that they cannot be improperly connected is strongly
recommended to avoid unnecessary problems later on when the cables are hidden
within the walls.
1T-CT-613 Repeater
The 1T-CT-613 Repeater is used to extend the signal distribution range provided when
using an HDMI to Cat.6 Transmitter and receiver system alone. The instructions that
follow assume you have already installed the appropriate Cat.5e or Cat.6 cables in the
desired areas of your building.
1. Repeater Video and DDC inputs are usually connected to the Cat.5e/Cat.6 cables at
the far end of a cable run (the end normally connected to the receiver inputs). In
essence, if the allowed signal distribution distance is insufficient to meet the
requirements, a repeater is inserted into the signal path. The cables coming from the
transmitter are plugged into the repeater inputs thereby allowing insertion of another
section of cabling into the path. At the far end of the desired distribution system, the 1TCT-612 Receiver is then connected to the Video and DDC cables connected to the 1TCT-613’s outputs. A 1T-CT-613 Repeater increases the total range by 45 meters (150
Feet) for 1080p/8 bit HDMI signals or 15 meters (50 feet) for 1080p/12 bit HDMI signals.
2. Connect a Cat.5E or Cat.6 cable to the Video input connector of the Repeater.
Connect a second Cat.5E or Cat.6 cable to the DDC input of the Repeater. Connect a
third Cat.5E or Cat.6 cable to the Video output connector of the Repeater and lastly
connect a fourth Cat.5E or Cat.6 cable to the DDC output of the Repeater. Mark all
cables at both ends so that you do not inadvertently swap them. The 1T-CT-613 does
not require external power.
Note: There are no user controls provided on the 1T-CT-613 Repeater. It’s important
that you should verify that the HDMI source functions properly with the HDMI display
device before you attempt to use any of the extender system components. Failure to do
this would introduce an unwanted variable that would then have to be resolved should
the system not function as expected.
Once the connections have been made and power applied, there are no operational
adjustments required. It is recommended however that the power on sequence be as
follows: HDMI to Cat.6 Transmitter and HDMI Cat.6 Repeater (if used), HDMI to Cat.6
Receiver, HDMI source and HDMI destination device – in that order.
Other than faulty or swapped Cat.5e/Cat.6 cables or attempting to use the product over
too great a distance, there are seldom problems with these Video Extender products.
If there is no image present at the remote location, connect the display device directly to
the source to make certain that the problem is not in the display. If an image is present
under those circumstances, make certain the transmitter and receiver(s) are receiving
power. Next make certain your Cat.5e/6 cable is defect free and the RJ-45 connectors
are securely attached to the cable at both ends. After trying the above suggestions
should the problem still persist, contact your dealer for additional suggestions before
contacting TV One. Should the dealer’s technical personnel be unable to assist you,
contact TV One via our support website: Create a
technical support request on the site and our support team will respond within a short
period of time.
