1. Product Overview
1.1. General Description
The etherRAIL product line is designed for use in industrial environments. The switches have
TX ports for lines in twisted pair configuration, and optionally via FX ports for cables in fiber
optic design. The FX ports enable network connections between widely extended network
segments and offer greater insensitivity to electromagnetic interference. The SM series
offers the user a cost-effective network expansion in a small enclosure with low power
consumption.
SM 4TX2FX SM 4TX 5TX M12
The 'plug and play' concept makes the device easy to use. The DIN rail mounting and a
device width of only 45mm ensure an easy expansion and exchange option. The terms of
protection degree, IP 20, are met. Two LED indicators signal the user for each TX and FX port
an existing connection to the link partner and information about the traffic.
The series was expanded to IP67 switch SM 5TX M12, which is suitable for the application
with harsh environmental conditions. It is designed for direct mounting without a control
cabinet. IP67 protection allows use in wet, dirty and dusty industrial environment even at
extreme temperatures. The small dimensions (L: 105mm x W: 60mm x H: 30mm) require
only a small footprint in machinery and equipment. Direct mounting as well as "plug-and-
play" concept enables a fast and inexpensive construction. The 5-TX Ethernet connections
are made via M12 connector with IP67 protection rating.

1.2. Interfaces and Displays
This section describes the Ethernet functionality on its physical level.
1.2.1. Ethernet Ports
The switch features depending on the type IEEE 802.3 10BASE-T and 100BASE-TX/FX
independent Ethernet interfaces. The TX ports are designed for twisted pair cable (TP)
cable with RJ45 connectors. The FX ports are designed for fiber optic cable with connectors
SC/ST- or alternatively for plastic optical cables as a direct connector.
Only TP cable with an impedance of 100 ohms can be used.
The pin assignment of the RJ45 connector is shown in Figure 1.1. Pins 1 and 2 transmit the
received data, while pins 3 and 6 transmit the data to be sent. The other pins are not used
for Ethernet transmission. The pin assignments for received and sent data can be
interchanged, since the switch has a crossover functionality for each port.
Figure 1.1.: Pin assignment of the Ethernet ports RJ45
The pair assignment for the receive line has to be properly connected.
The polarity of the switched RD + and RD is automatically reversed!
The inputs and outputs of the data lines are electrically isolated by an inductive coupler.
The Ethernet ports 1-5 of IP67 switch are in accordance with the IEEE802.3 standard and have 4-
conductor shielded and d-coded M12 connectors with the following assignment:
Pin 1: TX+
Pin 2: RX+
Pin 3: TX-
Pin 4: RX-
Figure 1.2.: Pin assignment of the Ethernet ports M12

1.2.2. Display of the Transmission Status
Each port has two LEDs near the Ethernet ports on the input side, which show the port status. The
meaning of the LEDs is described in the following table 1.1.
LED Function Status Description
Yellow Active Blink
Off
Transmit or receive activity
No transmit or receive activity
Green Link On
Off

No transmit (Link-down)
Chart 1.1.: Display of the transmission status
Each of the five Ethernet ports on the IP67 switches has a green signaling LED with the
following displays:
LED Status Description
Green Out
On

No connection
Connection, no transmit or receive
activity

1.2.3. Power-ON Display
Two green LEDs above the Ethernet ports show the functionality of the two power supplies. Both
power supplies are decoupled via a diode.
The IP67 switch contains a power LED, which is green, red or orange. Green corresponds of
startup, orange / green blinking means boot and red corresponds error.

Implementing the Switch
This chapter explains how to start the operating condition and the initial boot of the software
after turning on the switch.
2.1. Installation
When mounting and dismounting of the switch must be disconnected from the power supply!
2.1.1. Assembly and Disassembly of the Switch
The device (except SM 5TX M12) is designed for installation in the mounting rail according
to DIN EN 50 022. To avoid contact problems are only clean, rust-free rails to be used. The
device is automatically grounded by the snap onto the DIN rail, if the carrier rail is
grounded.
The grounding must be done in low impedance. A missing grounding can cause a
malfunction. The DIN rail must be mounted horizontally on a vertical surface, so
that the units for optimal heat dissipation sit upright.
Note: The free space above and below the mounted devices must be at least 50
mm for optimum heat dissipation.
Instructions for mounting the device see Figure 2.1:
1. Place the device on top of the DIN rail (A). The upper part of the clamp the must be
hooked onto the edge of the DIN rail. Press the device to the front towards the
mounting surface (B).
2. After the device has been snapped, check if it is fixed securely on the DIN rail. Check
that the locking tabs are facing upwards when locked into place.
3. In an extension insert the second device, as described above, next to the first device.
4. For a higher stability both devices can be fixed by a clamp at the corners of the device.
Figure 2.1.: Mounting a Switch
Page 12 of 45
Dismounting a device see figure 2.2.:
1. If the brackets are fixed, undo fixation first.
2. If several devices are assembled together, loosen the devices from one
another along the rail.
3. Pull the locking tabs downwards with a suitable tool (eg screwdriver).
The two latches remain in the disengaged state.
4. Swing the bottom of the device slightly away from the DIN rail (A).
5. Then lift the device up and away from the DIN rail (B).
Figure 2.2.: Dismounting a Switch
2.1.2.
Power Supply
Figure 2.3.: Power Supply via COMBICON
An integrated power supply unit regulates the voltage required for the device. The external supply
voltage of 24 V is applied across the four-pin COMBICON connector on the device, see Figure 2.4.
There is a polarity reversal in the case of applying the wrong polarity. It can tune cable from
0.2mm2. . . up to 2.5mm2 (AWG 24 ... AWG 14). To ensure a good contact, the cable ends must be
stripped about 10 mm. The power supply of IP67 switch 5TX M12 made together with the serial
communication via a 5-pin A-coded M12 connector:
Pin Nr. Bezeichnung Description
1 VCC Positive Terminal of the Supply Voltage
2 0V Negative Terminal of the Supply Voltage
3 TX RS232 Interface, Transmit Line
4 RX RS232 Interface, Receive Line
5 GND RS232 Interface, Signal Ground

2.1.3.
Alarm Contact
In case of a sudden power failure during operation, the switches (except SM 5TX M12) can give an
alarm. To avoid that the switch gives a false alarm, the alarm contact can be disabled via the web
interface (see Section 4.2.5).
Figure 2.5.: Schematic diagram alarm contact
2.1.4. Schnittstelle für externe Management
Every Device contains a USB or RS232 (SM 5TX M12) interface.
2.2. Power up the Switch
After an external power supply is present on the switch, the switch firmware is automatically loaded.
When the boot process is complete, the switch is operational.
2.2.1. Default Settings
The delivery status of the switch and the status after a reboot contain the following
settings:
• Port Configuration:
– TX- and FX-Ports are configured in 100 MBit/s full duplex mode.
– Auto-Negotiation and Auto-Crossover are activated for each TX-Port.
• IP-Configuration:
– IP-Address, Subnet and Gateway-Address will be set to 0.0.0.0 .
– The default address mechanism is BootP.
• Web Based Management:
– If the web server is enabled, the password is ’private’.
– SNMP is activated, no information about network devices, it is stored yet.
– RSTP and Multicast Filtering are deactivated.
To increase operational safety, we recommend that you change the password when the
switch is set to the operating mode, see chapter 4.2.
Page 14 of 45
2.2.2. Assigning IP Addresses
Figure 2.6.: Flowchart Assigning IP Addresses
By default, the switch receives its IP configuration via BootP, but there is also the possibility
of addressing mechanism via the web interface one-note, see Section 4.2.4. After the
switch is connected to the network, all addresses of the connected devices are stored. The
process in the switch during initial assignment of an IP-address is illustrated in Figure 2.6.
2.2.3. Web-based Configuration
The web server on the switch is enabled by default. To access the website of the switch, perform
the following steps:
1.
Ensure that the switch has started and that it is connected to the host via Ethernet.
2.
Open a browser of your choice.
3.
Enter the IP address of the switch in the address field, e.g., http://192.168.2.110.
4.
In successful cases you should see the following web page of the switch (see figure
2.7).
