Twisted pair (TP) cable advantages
Twisted pair cable is smaller, lighter, more flexible, and less
expensive than coaxial cable. Termination of the cable with
RJ-45 connectors is simple, quick, and economical.
Transmission distance
The maximum distance is determined by the frequency and
resolution of the signal that is input to the transmitter. The
table
on page 4
specifies the recommended maximum transmission
distances and transmitter Pre-Peak switch positions (
see item
e
on page 12) using Extron Enhanced Skew-Free A/V UTP cable,
DTP26 cable, or CAT 5, 5e, 6, or 7 cable, terminated with RJ-45
connectors.
N
The non-C7 transmitter and receiver are designed for
and perform best with Extron Enhanced Skew-Free
A/V cable terminated in accordance with the
TIA/EIA T 568 A wiring standard. CAT 5, 5e, and 6
cables are acceptable for the non-C7 models, but less
preferable. We also recommend the use of preterminated
and tested cables. Cables terminated on site should be
tested before use to ensure that they comply with
Category 5 specifications.
N
The use of DTP26 or CAT 7 cable with non-C7 products
has a negative effect on transmission distance. DTP26
or CAT 7 cable should only be used with C7 products.
N
The recommendations shown in the
table on page 4
apply
for a single transmitter and receiver and for a daisy
chain. For example, the maximum suggested range for
1024 x 768 video is 300 feet (90 m) with the Pre-Peak
switch off and 500 feet (150 m) with the Pre-Peak switch
on, whether the system consists of one transmitter and
one receiver or a transmitter and three daisy-chained
receivers.
N
For daisy-chained units, the first receiver in the chain
must be at least 100 feet (30 m) from the transmitter
when the Pre-Peak switch is on.
N
For daisy-chained units, any receiver in the chain closer
than 350 feet (105 m) may experience some form of over-
peaking when the Pre-Peak switch is on. An overpeaked
image may appear bloomed.
