SERVICING
Jumper J1 can be changed on the board to change the RJ45 copper port’s MDIX setting. See Connecting the Unit on page 9 for
more details.
DIN Rail Mounting
Install the unit on a standard 35mm DIN rail. Recess the unit to allow at least 5” of horizontal clearance for serial cable bend
radius.
To install the unit to 35mm industrial DIN rail, place the
top edge of the included mounting bracket on the back of
the unit against the DIN rail at a 15° angle as shown.
Rotate the bottom of the unit to the back (away from you)
until it snaps into place.
To remove the unit from the 35mm industrial DIN rail,
place a flat head screwdriver into the orange release clip
found at the bottom of the unit, and apply downward force
on the clip until it disengages from the bottom of the unit
from the DIN rail. Rotate the bottom of the unit towards
you and up at an approximate 15° upward angle to
completely remove the unit.
300-PM 900-PM
900-RM
With the exception of the 524TX and
526FX2, all N-Tron™ products are designed
to be mounted on industry standard 35mm
DIN rail. However, DIN rail mounting may
not be suitable for all applications. We offer
three alternative mounting solutions: Our 300
Panel Mount Assembly (P/N: 300-PM) may
be used to mount a single 100 or 300 Series
unit to a panel or other flat surface. Our 900
Panel Mount Assembly (P/N: 900-PM) may
be used to securely mount our 100, 200, 300,
400, 500, or 900 Series products to a panel or
other flat surface; Our Rack Mount Assembly
(P/N: 900-RM) may be used to mount our
products to standard 19" racks.

FRONT PANEL
From Top to Bottom:
Green LED lights when Power is connected
RJ45 Ports Auto sensing 10/100 BaseTX Connections
Serial RS232 serial port with DCE configuration
NOTE: The RJ45 data port has two LED’s located at the left side of the connector. The top LED indicates
Activity (ACT), and the lower LED indicates Link (LNK) status.
LED’s: The table below describes the operating modes:
LED Color Description
GREEN Power is Applied
OFF Power is OFF
GREEN 10/100Mb Link between ports
LNK OFF No Link between ports
GREEN Data is active between ports
ACT OFF Data is inactive between ports

APPLYING POWER (Top View)
Unscrew & Remove the DC Voltage Input Plug from the Power Input Header
Install the DC Power Cables into the Plug (observing polarity).
Plug the Voltage Input Plug back into the Power Input Header.
Tightening torque for the terminal block power plug is 0.22 Nm/0.162 Pound Foot.
Verify the Power LED stays ON (GREEN).
Note: Only 1 power supply must be connected to power for minimal operation. For redundant power operation, V1
and V2inputs must be connected to separate DC Voltage sources. This device will draw current from both sources
simultaneously. Use 16-28 gauge wire when connecting to the power supply.
Recommended 24V DC Power Supplies, similar to:
100VAC/240VAC:
N-Tron’s NTPS-24-1.3, DC 24V/1.3A,

GROUNDING TECHNIQUES
The grounding philosophy of any control system is an integral part of the design. N-Tron switches are designed
to be grounded, but the user has been given the flexibility to float the switch when required. The best noise
immunity and emissions (i.e. CE) are obtained when the N-Tron switch chassis is connected to earth ground via
a drain wire. Some N-Tron switches have metal din-rail brackets that can ground the switch if the din-rail is
grounded. In some cases, N-Tron switches with metal brackets can be supplied with optional plastic brackets if
isolation is required.
Both V- legs of the power input connector are connected to
chassis internally on the PCB. Connecting a drain wire to earth
ground from one of the V- terminal plugs as shown here will
ground the switch and the chassis. The power leads from the
power source should be limited to 3 meters or less in length.
As an alternate,
users can run a drain wire & lug from any of the Din-Rail
screws or empty PEM nuts on the enclosure. When using an
unused PEM nut to connect a ground lug via a machine screw,
care should be taken to limit the penetration of the outer skin
by less than 1/4 in. Failure to do so may cause irreversible
damage to the internal components of the switch.
The use of shielded cables between devices is not required for most N-Tron devices (please consult the user
manuals for specific details). If the use of shielded cables is required, it is generally recommended to only
connect the shield at one end to prevent ground loops and interfere with low level signals (i.e. thermocouples,
RTD, etc.). Cat5e cables manufactured to EIA-568A or 568B specifications are required for use with N-Tron
Switches.
In the event all Cat5e patch cable distances are small (i.e. All Ethernet devices are located the same local
cabinet and/or referenced to the same earth ground), it is permissible to use fully shielded cables terminated to
chassis ground at both ends in systems void of low level analog signals.
