3.0 CHECKING PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and make certain the
following items are contained in the shipping carton:
•1x Transmitter or Receiver unit
•1x Power Adapter (except 1T-CT-467)
•1x AC Power Cord (1T-CT-467 only)
•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.
4.0 CONNECTING THE HARDWARE
Please study the panel drawings below and become familiar with the signal input,
outputs, power requirements/inputs plus any controls present. Note: Each product has
somewhat different capabilities and therefore different cable connections are present.
Locate the drawing for the item(s) you have purchased and become familiar with the
connectors used in that product. The resolution capability of the remotely located
display devices must be capable of displaying the output of the source device. Before
connecting the CAT.5 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.
4.1 Cat.5/5E/6 Cable Notes
Pins and pairing. Make sure the CAT5/5E/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 (assign (assign
to pin pairs 1-2 & 7- 8), and B and D with low pitch twist (assign to pin pairs 3-6 & 4-5).

4.2 1T-CT-400 Series Transmitters
1. Connect the source device’s video output to the VIDEO IN connector of the
Transmitter, using the appropriate cable. All models except the 1T-CT-453 have
a VIDEO OUT connector that can provide a loop-thru signal to a local monitor.
2. All Transmitter models, except the 1T-CT-441, have audio capability. Connect
either the source device’s analog stereo or S/PDIF audio output to the either the
STEREO IN connector or the S/PDIF IN connector of the Transmitter (1T-CT-467
does not have S/PDIF in). Do not connect both as this will result in interference
between the two. The system is designed to support either audio format, but not
both at the same time. The audio output of the Transmitter can provide an
analog stereo signal for local monitor. If a S/PDIF input is used, this will be
converted to analog stereo for this purpose.
3. Connect a Cat.5/5E or Cat.6 cable to the UTP OUT connector of the Transmitter.
Model 1T-CT-467 has 8 UTP Outputs. All Transmitter models support up to 300
meters (1,000’) of CAT.5/5E or CAT.6 premium grade network cables as
described in 4.1 above. Model 1T-CT-467 has 8 UTP Outputs. The Receiver
model determines the maximum distance of either 150 meters (500’) or 300
meters (1,000’) of the cable as cam be determined by checking section 4.3
below.
Note – In addition to these three Transmitter models mentioned about, TV One
Models C2-1200 and C2-1250 Video Switcher/Scalers have built-in UTP transmitters
capable of sending either RGBHV or YPbPr format signals (without audio) up to
1000 feet. Consult the manual for those units when they are being used.

4.2 1T-CT-400 Series Receivers
1. At the remote location, connect the other end of the Cat.5/5E or Cat.6 cable to
the UTP IN connector of the Receiver.
2. Connect the VIDEO OUT connector of the Receiver to the video input of the
remote display or other device, using the appropriate cable.
3. If the Transmitter and Receiver models chosen have audio capability, connect
the Receiver’s STEREO OUT and/or S/PDIF OUT connectors to remote display
or other audio device. Both audio outputs may be used simultaneously,
regardless of the audio signal format chosen at the transmitter.
4. Connect the supplied AC adapters first to the respective Transmitter and
Receiver and then to the AC sockets.
5. 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.

5.0 OPERATING THE UNITS
Once the connections have been made and power applied, there is little in the way of
operational adjustments required. All Receivers have Equalization and Gain
adjustments. Additionally, the 1T-CT-444 and 1T-CT-456 have Skew Compensation
adjustments.
5.1 Equalization and Gain Adjustments
On all Receiver models, locate the EQ (Equalization) and GAIN adjustments on the side
of the Receiver.
On long cable runs, the high frequency detail can be lost resulting in a “soft” looking
picture. This will first show up in text where the characters will lose their sharp edges.
Adjust the EQ can sharpen the image. While viewing an image on a display connected
to the Receiver, insert a small screwdriver into the EQ adjustment on the side panel of
the Receiver. Rotate gently until the best EQ setting, as determined by image clarity, is
achieved.
Then insert the screwdriver into the GAIN adjustment, and rotate gently until the best
Gain setting, as determined by the brightness of the image is achieved. You may
notice an increase in video noise (sometimes called “snow”) in the picture at higher
gain settings so a compromise will have to be found if the cable run is at or near the
maximum length. EQ and GAIN settings are retained by the Receiver.
5.2 RGB Skew Compensation Adjustment
RGB images transmitted over long Cat.5/5E or Cat.6 cable paths can sometimes arrive
at the destination with the individual RGB pictures no longer in registration. Models 1T-
CT-444 and 1T-CT-456 have built in Skew Compensation adjustments to correct this.
This adjustment should be made after the EQ and Gain adjustments described above. A
good test pattern for RGB Skew adjustment is pictured below and is available for
download at the TV One Technical Support website http://tvone.crmdesk.com. After
saving the test pattern on the source PC, display and view it while making adjustments
on the remote display.

.
If you want to nudge the blue image to the left, make sure the blue LED is blinking, then
hold the nudge button in and wait until the blue LED is blinking. Then tap the Nudge Left
button repeatedly. Each tap will result in a tiny incremental move to the left. There are
32 increments in this adjustment. To shift the blue image to the right, make sure the
blue LED is still blinking and tap the Nudge Right button repeatedly. To adjust the Red
and Green images, repeat the process, making sure the color you want to adjust is
blinking. Adjust the Skew controls until the Red, Blue and Green images are vertically
aligned and the white vertical lines show no prismatic halos. When complete, release
the adjustment buttons and in 30 seconds the LED will stop blinking and the Receiver
reverts to normal operation and the Skew adjustment settings are retained in memory.
6.0 TROUBLESHOOTING
Other than faulty cables or attempting to use the product over too great of distances,
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.5/5E/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:
http://tvone.crmdesk.com. Create a technical support request on the site and our
support team will respond within a short period of time.
Locate the RGB Skew Adjust buttons on the side of
the Receiver. While watching the remote display,
press and HOLD either RGB skew adjust button. After
three seconds, the RGB adjust indicator LED starts
blinking; Receiver is now in RGB Skew Adjust Mode.
The color of the blinking LED indicates the color being
adjusted. Colors cycle if you hold the button down
steadily.
