Overview: 308FX2/309FX/316TX/317FX Industrial Ethernet Switches
The 308FX2/309FX/316TX/317FX Industrial Ethernet Switches support high speed layer 2 switching
between ports. The copper ports in this line are Category 5 compliant 10/100-BaseTX connections for
high performance network design, and hub/repeater upgrades. These copper ports are capable of auto
negotiating 10/100 Mb and half/full duplex communications, or the user can configure these parameters.
The 308FX2 is an affordable 8 port switch that has 6 copper ports plus two additional multimode fiber
optic up-link ports. The two fiber links are capable of 2 Kilometers of 100 Mb communications without
the use of repeaters.The 308FXE2 is similar to the 308FX2, but is populated with singlemode extended
range fiber optics.
The 316TX is an affordable 16 port copper port switch.
The 309FX (317FX) is a 9 (17) port switch that has 8 (16) copper ports, plus an additional multimode
fiber optic up-link port in the 309FX and in the 317FX. These fiber links are capable of 2 Kilometers of
100 Mb communications without the use of repeaters.
The 309FXE (317FXE) is a 9 (17) port switch that is similar to the 309FX (317FX), but with extended
range. The FXE versions utilize a singlemode fiber transceiver that is capable of 15-80 Kilometers of
200 Mb communications.
All FX, FX2, FXE, and FXE2 models utilize the IEEE compliant SC or ST duplex connector for fiber
optic communications. The 10/100Base-TX ports utilize the RJ45 shielded connector.
All N-TRON 308FX2/309/316/317 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 308FX2/309/316/317 units operate on 10-30VDC.

Applying Power (Side View)
Unscrew & Remove the DC Voltage Input Plug(s) from the side header
Install the DC Power Cables into the Plug(s) (observing polarity).
Plug the Voltage Input Plug(s) back into the side header.
Tightening torque for the terminal block power plug is 0.22 Nm/0.162 Pound Foot.
All LED‟s will flash ON Momentarily
Verify the Power LED stays ON (GREEN).
Note: Only 1 plug must be connected to power for minimal operation. For redundant power operation,
V1and V2plugs must be connected to separate DC Voltage sources. Use wire sizes 16-28 gauge. The
power cord should be limited to less than 10 meters in order to ensure optimum performance.
Recommended 24V DC Power Supplies, similar to 100VAC/240VAC:
N-Tron‟s NTPS-24-1.3, DC 24V/1.3A.

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. Please note that the minimum cross-
sectional area of the grounding conductor must be at least 4mm2
and it must be suitable for use in temperature of 110°C.
Note: Ensure the power supply is grounded properly before applying
power to the grounded switch. This may be verified by using a
voltmeter to determine that there is no voltage difference between the
power supply‟s negative output terminal and the chassis grounding
point of the switch.
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.

(Revised 2010-7-30)

RJ45 Connector Crimp Specifications
Please reference the illustration below for your Cat5 cable specifications:
Connecting the Unit
For FX/FXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables. The TX
port on the FX/FXE models should be connected to the RX port of the far end station. The RX port on the
FX/FXE versions should be connected to the TX port of the far end station.
For 10/100 Base-TX ports, plug a Category 5E 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. To connect
any other port to another Switch or Repeater, use a standard Category 5 straight through or 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!
Note: For units which have the N-View Option (-N), you can validate that all ports are working correctly by
installing the N-View OPC Server software. The software is freely distributed on the ProductCD and our website
(http://www.n-tron.com/pdf/nview_opc_manual.pdf ). Once the software is installed, you should view the Ports
Counter page to remotely monitor each connected port. You may find it helpful to copy [Alt]+[Print Screen] 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.

Serial Interface
The 308FX2/309/316/317 switches provide an EIA-232 interface accessed via a 9 pin female connector (labeled
„COM‟ on the unit). This is used to access the Command Line Interpreter (CLI). The pin-outs are shown below:
Pin 6
Pin 7
Pin 8
Pin 9
Pin 1
TXD Pin 2
RXD Pin 3
Pin 4
GND Pin 5
Serial Cable
Connect the serial COM port of your PC and the 308FX2/309/316/317 Switch using a standard straight through
cable. You will require a cable with a 9-pin or 25-pin sub-D female connector for the PC end, and a 9-pin male
sub-D connector for the 308FX2/309/316/317 end.
The following table shows the pin-out and the connections for both types of cable:

Troubleshooting
1. Make sure the (Power LED) is ON.
2. Make sure you are supplying sufficient current for the version chosen.
3. Verify that Link LED‟s are ON for connected ports.
4. Verify cabling used between stations.

(Revised 2010-7-30)
16
5. Verify that cabling is Category 5E or greater for 100Mbit Operation.
6. For FX/FXE models, verify TX is connected to far end RX and vice versa. Also insure the
connecting partner is 100Mb/s IEEE 100BaseFX compliant. Note: the 308FX2/309/316/317
FX/FXE switches do not support the 10BaseFL standard.
