Figure 1 — Typical SEQ 100 BNC application
UTP cable test equipment measures and reports wire pair
length. The report on the various pair lengths can be used to set
the SEQ 100 to properly equalize pair skew.
If UTP cable test measurement cannot be done, pair skew can
still be equalized by viewing a test pattern with a critical eye.
Examine the test pattern for loss of horizontal registration and,
through a process of trial and error, equalize any pair skew with
the SEQ 100.
The SEQs are a part of the Extron VersaTools
® line of basic
distribution amplifiers, switchers, transmitters, SEQs, and
associated video accessories. The rack- and furniture-mountable
equalizer has an external power suppy with worldwide
compatibility.
Installation
The 1U high, quarter rack width, SEQ 100 can be be placed on
a tabletop, mounted on a rack shelf, mounted to a rack without
a shelf, mounted under a desk or tabletop, or mounted on a
projector bracket.
Tabletop placement
Affix the four included rubber feet to the bottom of the unit and
place it in any convenient location.
Rack mounting
UL requirements
The following Underwriters Laboratories (UL) requirements
pertain to the installation of the SEQ into or onto a rack.
1
. Elevated operating ambient — If installed in a closed
or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater
than room ambient. Therefore, consider installing the
equipment in an environment compatible with the +122 °F
(+50 °C) maximum ambient temperature (Tma) specified
by Extron.
2 . Reduced air flow — Installation of the equipment in a rack
should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
3 . Mechanical loading — Mounting of the equipment in
the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
4 . Circuit overloading — Consideration should be given to
the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on
overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be
used when addressing this concern.
5 . Reliable earthing (grounding) — Reliable earthing
of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections
other than direct connections to the branch circuit (such as
the use of power strips).
