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.

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 s howing 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).
