3. Router Description
SmartFlex SR305 is an industrial cellular router intended for the North American market
(NAM). This router is an ideal device for wireless communication in mobile networks that make
use of LTE, HSPA+, UMTS, EDGE or GPRS technology. Due to the high speed of data transfer
(up to 100 Mbit/s download and up to 50 Mbit/s upload) this router is an ideal solution for
specialized M2M devices and IoT as well as for wireless connection of traffic and security
camera systems, individual computers, LAN networks, automatic teller machines (ATMs) and
other self-service terminals.
The standard configuration includes two Ethernet 10/100 ports, one USB 2.0 Host port,
two binary inputs and one output (I/O connector). The device also has two readers for 3 V and
1.8 V SIM cards, which are located on the rear panel of the router. The router also includes
a microSD card port that supports up to 64 GB card storage (32 GB in the case of SDHC
cards). The router can be equipped with a WiFi module, but this must be part of the initial
configuration – it cannot be added to the router at later date.
The router can be equipped with PoE PD (Power over Ethernet – Powered Device), which
allows the router to be powered via Ethernet. It can also be equipped with PoE PSE (Power
over Ethernet – Power Source Equipment), which enables the router to power other devices via
Ethernet. The SmartFlex can also be configured with a wide variety of port options. Options
include SWITCH – three switched Ethernet ports; RS232-RS485/422 – combination of serial
interfaces; RS232-RS485-ETH – combination of serial interfaces and an Ethernet port with
higher insulation. The router can be supplied in either plastic or metal casing, depending on
customer requirements.
The router can be configured using a password-protected Web interface. The Web interface provides detailed statistics about the router’s activities, signal strength, detailed system
logs etc. The router supports the creation of VPN tunnels using IPSec, OpenVPN and L2TP
to ensure safe communication. DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS,
primary connection backups and many other functions are also supported.
The router performs diagnostic functions including automatic monitoring of the PPP connection, automatic restart in case of connection losses, and a hardware watchdog that monitors the router status. It is possible to insert Linux scripts in order to perform various actions. It
is also possible to create up to four different configurations for the same router. These configurations can be switched between at any via the Web interface, SMS or binary input status. The
router can automatically upgrade its configuration and firmware from a central server, allowing
for the mass reconfiguration of numerous routers at the same time.
The router also supports additional software such as R-SeeNet for permanent traffic monitoring of routers.

5.5 Mounting recommendations
SmartFlex SR305
• It is possible to place the router on a flat surface,
• DIN rail EN 60715 with the included plastic or metal clip.
For most applications with a built-in router within a switchboard it is possible to recognize
two kinds of environments:
• A non-public, industry environment of low voltage with high interference,
• A public environment of low voltage and without high interference.
For both of these environments it is possible to mount router to a switchboard, after which
there is no need to have examination immunity or issues in connection with EMC according to
EN 61439-1:2011.
Attention: If the negative pole of the router is grounded, there is no protection against
reversed polarity!
In compliance with the EN 61439-1:2011 specification it is necessary to observe the
following assembly instructions for a router attached to a switchboard:
• For whip antennas it is recommended to observe a minimum distance of 6 cm from
cables and metal surfaces on every side in order to avoid interference. When using
an external antenna seperate from the switchboard it is necessary to fit a lightening
conductor.
• When mounting a router on sheet-steel we recommend using a "cable" antenna.
• For all cables we recommend to bind the bunch, and for this we recommend:
16
SmartFlex SR305
– The length of the bunch (combination of power supply and data cables) should be a
maximum 1.5 m. If the length of data cables exceeds 1.5 m or if the cable is leading
towards the switchboard, we recommend installing surge protectors.
– Data cables must not have a reticular tension of ∼ 230 V/50 Hz or ∼ 120 V/60 Hz.
• Sufficient space must be left between individual connectors for the handling of cables,
• To ensure correct functioning of the router we recommend the use of an earth-bonding
distribution frame for the grounding of the power supply of the router, data cables and
antenna within the switchboard.
5.6 Removal of the DIN rail
The DIN holder is suitable for a DIN rail according to EN 60715 standard only. The default
position of of plastic or metal holder, which is used for mounting the router on a DIN rail, is
shown in the following figure:
Figure 23: Default position of DIN holder
In order to remove the DIN rail it is necessary to lightly push the router upward so that the
top part of the DIN holder hitched to the DIN rail comes out of this rail, then fold the top of the
router away from the DIN rail.

* Additionally it can indicate a device without PoE support connected on the other side of the
cable. In this case the indication is caused by low impedance (lower than 500 Ω) of the device
without PoE support. This can be solved by disabling the PoE PSE feature on the relevant
ETH port in the router’s Web interface, see Configuration manual [2].

The power supply for the router must be between +10 V to +60 V DC supply. Protection
against reversed polarity without signaling is built into the router. Note: The protection against
reversed polarity is lost if the negative pole is grounded!
The router can be put into low power mode using a special command lpm. It can then be
awakened, for example, by an activity on binary input or using an internal timer.
Circuit example:
Figure 27: Connection of power supply
Note for PoE: See Chapter 5.8.7 for information on how PoE versions of the router
impact the power supply usage. The power supply for a PoE PSE router has to meet
other specific requirements.

5.8.3 Antenna connector ANT, DIV, GPS and WiFi
The main, diversity and GPS antennas are connected to the router using the SMA connector on the front panel. There is also an R-SMA antenna connector available, through which an
additional antenna can be connected, if the router is equipped with a WiFi module.
The ANT connector is used to connect the main antenna to the router. To connect the
diversity antenna, the second antenna connector DIV is used. The third connector (GPS) is
intended for a GPS antenna (the router supports active GPS antennas). An R-SMA connector
named WiFi is designed for the connection of a WiFi antenna (available only for versions with
a WiFi module).
The router can not operate without a main antenna connected through the port marked
as ANT !
An SMA connector is used for the connection of the antenna. The antenna is connected by
screwing this antenna to the SMA connector on the front panel of the router (see figure below).
Figure 28: Connecting the antenna
A diversity antenna improves the radio capability of the router at low signal strength.

5.8.4 SIM card reader
Two SIM card readers for 3 V and 1.8 V SIM cards are located on the rear panel of the
router. In order for the router to function, it is necessary to insert an activated SIM card with
an unblocked PIN code. The SIM cards may have different adjusted APNs (Access Point
Names).
Changing the SIM card:
• Always disconnect the router from power supply before handling the SIM card!
• Using a plastic opening tool, or your fingernail, press the SIM card slightly into its
slot until you hear a click.
• After hearing this click, release the card and it will pop out of its slot.
• Remove the SIM card and push any other SIM card into the slot until it clicks into
place.

The insulation strength of Ethernet ports from each other and from the rest of the router
(grounding) is dependent on the router version:
Router Version Insul. Strength from Router Insul. Strength between Ports
Without PoE 1.5 kV 1.5 kV
PoE PD 1.5 kV none
PoE PSE none none
Table 12: Insulation strength of Ethernet ports
5.8.7 Power over Ethernet (PoE)
On the router models with PoE, the PoE+ standard IEEE 802.3at-2009 and PoE standard
IEEE 802.3af-2003 are supported in both Ethernet ports (ETH0, ETH1). The PoE PD version
allows the router to be powered over the Ethernet by another PoE PSE device. The PoE PSE
version also allows the router to power other devices over the Ethernet.
PoE PD
Figure 33: PoE PD usage
24
SmartFlex SR305
The PoE PD parameters can be found in Chapter 7.8. The POE LED on the front panel
of the router lights up green when voltage is present in an Ethernet port so the user knows
the router can be PoE powered. You can still power the router with this connector even if the
router is powered with PoE (in PoE PD version), but the input voltage must be higher than
15 V DC. If the input voltage is lower than 15 V DC and the PoE voltage is present (PoE LED
green on), the router will still be powered from the Ethernet connector via PoE.
Note: You can not power the router via the SWITCH version ETH2 connectors. The PoE
PD is available on the ETH0 and ETH1 ports only.
PoE PSE
Figure 34: PoE PSE usage
The power supply used with the PoE PSE router has to provide voltage from 44 to
57 V DC and the output power has to be at least 65 W for full PoE+ use (Class 4) in
both Ethernet ports (ETH0 and ETH1).
The PoE PSE parameters can be found in Chapter 7.8. The PoE state is indicated by the
POE LED on the front panel of the router, see Chap. 5.8.1. When sufficient voltage (44 to
57 V) and power is available is indicated by the green light. A yellow POE LED indicates
insufficient power or voltage through the PWR connector. When a device is being powered
from the router, the POE LED is will show blinking green. Yellow blinking is shown for an
overload (the powered device is using too much power) or a short circuit (incorrect wiring of
the cable or of the device without PoE support).
You can enable or disable the PoE PSE feature separately on the ETH0 and ETH1 ports
via the Web interface of the router. This can be found in the LAN configuration pages (Primary
for ETH0, Secondary for ETH1). When PoE PSE is enabled, you can find the current, voltage,
power and power class information on the General page of the router’s Web interface. See
the Configuration manual [2]. Via SSH or in scripts you can use the Shell command pse.

The three LAN ports of the SWITCH interface for SmartFlex routers (RJ45 connectors for
connecting Ethernet devices) act as a typical switch device. This means that the router reads
Ethernet frames (data packets on an Ethernet link) from any port on the SWITCH interface and
transmits them on other ports of the SWITCH interface. Each port can transmit frames independently on the other ports. State indication is displayed separately on each connector. These
router versions comply with the standards and temperature ranges stated in Chap. 7.1 except
for having a lower maximum operating temperature, which is +70◦C.

6.2 Start
The router will start when a power supply is connected to the router. By default, the router
will automatically start to log on to the default APN. The DHCP server will start to assign
addresses for devices connected through the Ethernet port ETH0. These router behaviors
can be changed via the web interface. This is described in detail in the Configuration manual
for SmartFlex routers.
6.3 Configuration
Attention! If no SIM card is inserted in the router, it is not possible for the router to
operate. Any inserted SIM card must have active data transmission.
6.3.1 Configuration by web browser
For status monitoring, configuration and administration of the router a web interface is
available which can be accessed by entering the IP address of the router into the web browser.
The default IP address of the router is 192.168.1.1. Attention, it is necessary to use HTTPS
protocol for secure communication over a network!

9. Troubleshooting
If you cannot connect to the router from your PC, your network card may be configured
in such a way that it is not possible to connect to the router. Take one or more of the
following steps in order to solve the problem:
• Set the communication rate to 10 MB/s in the properties of your network card.
• Connect the router to the PC via Switch.
• Connect the router to the PC, start the router first and then star t the PC after the
router’s initialization.
9.1 FAQ
- I have NAT enabled. My equipment is not connecting to the network.
• The device’s gateway has to be configured the same as the router’s.
- The router resets itself and the Ethernet connection fails.
• The router will not function without an antenna. Keep the antenna as far as possible
from the power supply.
- I can’t access the Web server over NAT.
• The remote HTTP access of the router has to be disabled, the default server address has to be your web server and the gateway of the web server has to be the
IP of the router.
- Mobile WAN connection fails. (DAT LED off)
• Check the signal power. If the signal power is weak, you will have to use a better
antenna. If the neighboring cells have a similar signal strength, you will need to use
a directional antenna. For proper operation, the signal levels have to be within the
range of -50 dBm to -90 dBm.
• It is necessary to set the router to ping, which will check the connection and, in the
case of a failed ping, restart the connection.
- Mobile WAN connection cannot be established. (DAT LED off)
• Check the GPRS settings – APN, name, password and IP address.
• Try to enter the SIM card PIN – verify that the SIM card has the PIN code entered.
• In a private APN, switch the DNS server send off.
• Switch the system log on and observe to see where the error occurs.
47
- Ethernet connection fails or isn’t establishing.
• It is possible to turn auto negotiation off and set a rate and duplex manually on the
Ethernet interface of the router.
- DynDNS doesn’t function.
• With private APN this is not functional.
• If the same IP address is recorded in your canonic name as a dynamically assigned
address, it means that the operator is using NAT or a firewall.
• Verify NAT using ping to the static server address.
• Verify a Firewall by accessing remotely to the router’s Web interface.
• The operator may not provide the address of DNS server and without DNS server’s
address it is impossible to connect to the dyndns.org server. The following messages will be shown in the system log:
– DynDNS daemon started
– Error resolving hostname: no such file or directory
– Connect to DynDNS server failed
SmartFlex SR305
- L2TP or IPSec isn’t establishing.
• Check the system log for error messages.
- I switched the router to offline mode by SMS message, but the router is in online
mode after restart.
• SMS messages do not change the router configuration. They remain in effect only
until the router is restarted.
- RS232 doesn’t function.
• Verify that the router supports RS232 communications. Also verify the RS232 communication settings. To do so, open the router’s configuration menu via the web
browser, select the appropriate expansion port and verify the settings in the configuration menu.
