3 Overview
The TP-185 is a high performance, 8 channel VGA/UXGA
1
In particular, the TP-185, 8 Channel UXGA/Audio/RS-232 to CAT 5 Transmitter
features:
, audio and RS-232 to CAT 5
transmitter for high resolution video, stereo unbalanced audio and RS-232 signals. The
CAT 5 outputs can be connected to any Kramer compatible TP receiver, for example, the
TP-126. The TP-185 can also route data from the RS-232 or RS-485 port to any of the
CAT 5 outputs.
• Eight UXGA video inputs
• Eight stereo unbalanced audio inputs on 3.5mm mini jacks
• Eight RJ-45 STP/UTP outputs
• Transmission of RS232/RS-485 data from one input to any or all of the eight
CAT 5 outputs, and one reply from the selected output
The TP-185 can differentiate between RS-232/RS-485 commands that control the unit
itself and commands that are destined for end-user equipment (see
Section 7.1.5.2
The TP-185 is dependable, rugged, and fits into one vertical space (1U) of a standard
19” professional rack.
).
To achieve the best performance:
• Use only good quality connection cables 2
• Do not secure the cables in tight bundles or roll the slack into tight coils
to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
• Avoid interference from neighboring electrical appliances that may adversely
influence signal quality, and position your Kramer TP-185 away from
moisture, excessive sunlight and dust
3.1 Shielded Twisted Pair/Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable. There are different levels
of STP cable available, and we advise you to use the best quality STP cable that you can
afford. Our non-skew-free cable, Kramer BC-STP is intended for analog signals where
skewing is not an issue. For cases where there is skewing, our UTP skew-free cable Kramer
BC-XTP, may be used. Bear in mind though, that we advise using STP cables where
possible, since the compliance to electromagnetic interference was tested using those
cables. Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, the UTP cable should be installed far away from electric cables, motors and so
on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.
