405FX, 405FXE, & 405TX Industrial Ethernet Switches
The 405TX and 405FX Unmanaged Industrial Ethernet Switches support high speed layer 2 switching
between ports.
The 405TX is an affordable 5 port unmanaged switch that is capable of auto negotiating 10/100 Mb and
half/full duplex communications. The N-TRON 405TX is housed in a ruggedized steel enclosure, and
provides 5 Category 5 compliant 10/100-BaseT connections for high performance network design, and
hub/repeater upgrades.
The 405FX is a 5 port unmanaged switch that has 4 ports identical to the 405TX, plus an additional
multimode fiber optic up-link port, capable of 2 Kilometers of 100 Mb communications without the use of
repeaters.
The 405FXE is a 5 port unmanaged switch that is similar to the 405FX, but with extended range. The N-
TRON 405FXE utilizes a singlemode fiber transceiver that is capable of 15 Kilometers of 100 Mb
communications.
Both the 405FX and 405FXE utilize the IEEE compliant SC or ST duplex connector for fiber optic
communications. The 4 10/100Base-TX ports utilize the RJ45 shielded connector.
All N-TRON switches come housed in a steel ruggedized Din-Rail enclosure, designed to withstand the
most demanding industrial applications, and have been fully tested and certified at industrial environmental
extremes. All 405 Units operate on 10-30VDC @ 0.2A.

405FX/405FXE HALF DUPLEX SETUP
While all RJ45 ports are Autosensing, the 405FX/405FXE Fiber Optic Port is factory configured for full
duplex operation. In the event half duplex operation is desired, follow these steps:
1. Remove the Voltage Input Power Plugs.
2. Remove the top cover (8 screws).
3. Remove the jumper plug (JP1) from pins 1 and 2.
4. Replace the top cover.
5. Proceed with the installation.
Full Duplex = Pins 1 and 2 shorted.
Half Duplex = Remove jumper.
In order to verify the jumper settings have been set correctly, for units which have the N-View option turned
on, you should install N-ViewOPC Server software on a PC connected to the LAN. The software is freely
distributed on the ProductCD and our web site ( http://www.n-tron.com/html/opc.html ). Once N-ViewOPC is
installed, you should view the Ports Counter page to remotely monitor each connected port. You may find it
helpful to Copy [Alt]+[PrintScreen] the Port Counter information for each port and Paste [Control]+[V] into a
Windows document for further review. Please consult your N-View OPC Server Manual for additional
information.

DIN-Rail Mounting
Install the unit in a standard DIN-Rail. Recess the unit to allow at least 5” of horizontal clearance for fiber optic
cable bend radius (2” for TX models). Note: This unit may be mounted horizontally or vertically.
To install the unit to 35 mm industrial DIN-Rail - Place the top edge of the included mounting bracket on
the back of the unit against the top flange of the DIN-Rail at a 15° angle. Rotate the bottom of the unit to the
back (away from you) until it snaps into place.
To remove the unit from the 35 mm industrial DIN-Rail - Apply downward force to the unit until it
disengages from the bottom of the unit from the DIN-Rail. Then, rotate the unit approximately 15° upward
and towards you to completely remove the unit.
Optional Mounting
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 two alternative mounting solutions.
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 Universal Rack Mount Kit (P/N: URMK) may be used to mount our products to standard 19" racks.

N-TRON SWITCH 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.
Note: Before applying power to the grounded switch, you must use a volt
meter to verify there is no voltage difference between the power supply’s
negative output terminal and the switch chassis grounding point.
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.

CONNECTING THE UNIT
For 405FX & 405FXE units, remove the dust cap from the fiber optic connectors and connect the fiber
optic cables. The TX port on the 405FX should be connected to the RX port of the far end station. The
RX port on the 405FX should be connected to the TX port of the far end station.
For 10/100 Base-TX ports, plug a Category 5 twisted pair cable into the RJ45 connector. Connect the
other end to the far end station. Verify that the LNK LED’s are ON once the connection has been
completed. For Switch to Switch or Switch to Repeater connections, use the X-port and a standard
Category 5 cable. To connect any other port (other than the X-Port) to another Switch or Repeater, use a
standard Category 5 crossover cable.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation and
will create a broadcast storm which will crash the network!
TROUBLESHOOTING
1. Make sure the (Power LED) is ON.
2. Make sure the ! (Error LED) remains OFF 3 seconds after initial power up.
3. Verify that Link LED’s are ON for connected ports.
4. Verify straight through cabling used between stations.
5. Verify crossover cabling used between switches or repeaters (non X-Port only).
6. Verify that cabling is Category 5 for 100Mbit Operation.
7. Verify TX is connected to far end RX and vise versa (405FX/FXE only).
