Half Normalled Bottom Half Normalled Top Full Normalled Parallel Isolated
122
The standard version of the NPPA Panel is delivered bottom row
half normalled for each jack pair by default. Further patch ver-
sions are available with fully loaded jack-pairs as:
L
Full Normalled
L
Half Normalled
L
Isolated
L
Parallel
For individual normalling single pre-configured jack-pairs
are offered.
NPPA-TT-IDC is equipped with jumper blocks for individual
switching configurations of each jack channel.
Note: Take care when handling digital signals. Do not use
parallel configuration and avoid other parallel paths when
using half normalled configurations. Parallel paths may lead
to mismatching.
The flexible grounding system provides the following versions:
L
Individual: Each channel is individually grounded by its corresponding cable shield (default configuration).
L
Group: Selected channel grounds are connected via the ground bus on the PCB using solder bridges and track cuts to form a
group that is connected to one common cable shield.
L
Central: All channel grounds (individual top and bottom row) are connected via the ground bus on the PCB using solder
bridges and wired with only one cable shield.
L
Chassis-Common: The same as central grounding but with the addition of the common ground bus (top and / or bottom
rows) connected to the patch panel chassis by means of jumpers
TT Patch Panels offer different choices of wiring:
L
Spring loaded push terminals
L
56 pin Elco/Edac male connectors
L
90 pin Elco/Edac connectors
L
50 pin D-SUB connectors
L
25 pin D-SUB connectors
L
IDC-Krone terminals
L
Solder lugs
The spring loaded terminal blocks enable fast and easy wir-
ing. No soldering and screwing necessary. Simply insert the
stripped wire after pressing down the white key. Terminals
accommodate stranded wires up to AWG 20 (0.5 mm
2
) and
solid wires up to AWG 18 (0.75 mm
2
). Push terminals are
gas tight connections.
All panels are fitted with high quality, long life Neutrik
®
NJ3TTA gold plated double contact jacks (2 x 48), featuring
drastically improved contact integrity and are available with
a wide choice of wiring terminations. The unit is finished off
with a built in cable bar and two large channel ident strips
for perfect management of the system.
The new generation of the Neutrik
®
”Easy-Patch” is easily
programmable for any one of five configurations (standard
is half normalled bottom row) and for the grounding system
of your choice. Each individual pair of jacks can be changed
or reconfigured quickly and without fuss even while the
panel is ”on air”. The NJ3TTA jacks offer also two contact
points per terminal (TRS) with a special designed mechanism
for the normalling contact. Simply remove the front panel to
reveal the easy access jack. Remove, replace or reconfigure
the jack and refix the panel.
The ”Easy-Patch” is an innovative and compact patching
system (just 1U high) for 19" rack mounting. Robustly
housed in a black coated steel shell and featuring precision
aluminium fittings it is built to last.
