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-445 Transmitter
1. Connect the source device’s video output to the VIDEO IN connector of the
Transmitter, using the appropriate cable. The 1T-CT-445 has a VIDEO OUT
connector that can provide a loop-thru signal to a local monitor.
2. The 1T-CT-445 Transmitter has RS-232 control capabilities. Connect an RS-232
cable to the RS-232 Input at this time if you are using this functionality.
3. Connect a Cat.5/5E or Cat.6 cable to the UTP OUT connector of the Transmitter.
The 1T-CT-445 Transmitter supports transmission distances of up to 300 meters
(1,000’) of CAT.5/5E or CAT.6 premium grade network cables as described in
4.1 above. Receiver model determines the maximum transmission distance of
either 150 meters (500’) or 300 meters (1,000’.) Seesection 2.2 above for
details.

7
4.3 1T-CT-454 and 1T-CT-458 Receivers
1. Connect the Cat.5/5E or Cat.6 cable to the UTP IN connector of the Receiver.
2. For either a 1T-CT-454 or 1T-CT-458 Receiver, connect the RS-232 cable at this
time if you are using the RS-232 functionality.
3. Connect the VIDEO OUT connector of the Receiver to the video input of the
remote display or other device, using the appropriate cable.
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.

4.4 Special Instructions: 1T-CT-445 Transmitter & 1T-CT-454, 458 Receivers
The following instructions apply to systems using DDC2B/EDID capable monitors.
You must follow the sequence listed below in order for the EDID automatic monitor
resolution detection to work properly.
Note: If your monitor is not EDID capable, you can follow the instructions listed in
sections 4.2 and 4.3 above instead of those listed below.
1. Make certain that power to all devices you will be connecting is turned off.
2. Connect VGA cable from the computer and the RS-232 cable to the 1T-CT-445
Transmitter.
3. Connect the Car 5/5E or Cat.6 cable to the 1T-CT-445 Transmitter.
4. Connect the 1T-CT-454 or 1T-CT-458 Receiver to the EDID Capable Monitor.
5. Connect the RS-232 Cable to the Receiver.
6. Connect the Cat.5/5E or Cat.6 cable to the Receiver.
7. Apply power to the monitor.
8. Connect the AC adaptor to the Receiver and then to the AC power socket.
9. Connect the AC adaptor to the 1T-CT-445 Transmitter and then to the AC power
socket.
10.Apply power to the computer.

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-458 has a Skew Compensation adjustment.
