Router Description

Cellular router SmartStart SL302 is designed for wireless communication in mobile networks that use traditional cellular technologies. The primary purpose of this router is its use in the newest Category 1 (Cat.1) services on the cellular LTE network of the AT&T and Verizon carriers.

LTE Category 1 (Cat.1)

Given the uncertain future of 2G technologies (they are gradually sunsetting), it needs to find a suitable (natural) replacement. LTE Category 1 (Cat.1) in general is the only real alternative to 2G. It is specifically designed to bring 4G LTE capabilities to the Internet of Things (IoT) and machine-to- machine (M2M) applications. Like all LTE services,  Cat.1 provides a low- latency broadband connection but is capped at 10 Mbps download (and 5 Mbps upload). It is an ideal solution for smart meters for utilities, telematics for vehicle tracking, and fleet management and security use cases, such as in alarm systems.

3.2 Basic HW Information
As a standard, the SmartStart router is equipped with one Ethernet 10/100 Mbps, one serial interface RS232, one binary input, and one output. SL302 also contains two readers for 3 V and 1.8 V SIM cards, which are placed on the rear panel of the device. The router can be equipped with a WiFi module, but this must be part of the initial configuration – it cannot be assembled to the router at some point in the future. The router is supplied in a plastic casing.

3.3 Configuration and Diagnostics
The router can be configured using a password-protected Web interface. The web interface provides (after logging in) detailed statistics about the router activities, signal strength, detailed system logs, etc. This device supports the creation of VPN tunnels using technologies IPSec, OpenVPN, and L2TP for secure communications. There are also supported functions such as IPv6 (the latest revision of the Internet Protocol), DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS, primary connection backups, and many other functions are also supported.
Other diagnostic functions ensuring continuous communication include automatic inspection of PPP connection offering an automatic restart feature in case of connection is lost, or a hardware watchdog that monitors the status of the router. Using a special window (start-up script window) you may insert Linux scripts for various actions. For some applications is the key possibility to create several different configurations for one router which can be switched as needed (e.g. using SMS or status of the binary input). Cellular routers may automatically update configuration and firmware from the server. This allows mass reconfiguration of many routers at one time.

The router also supports additional software such as R-SeeNet for permanent traffic monitoring of routers.

Examples of possible applications

• mobile office
• smart meters for utilities
• fleet management
• security systems| • telematic
• telemetric
• remote monitoring
• vending and dispatcher machines

5.5 Mounting recommendations

• It is possible to place the router on a flat surface,

• mount the router on a wall using four holes in corners (Figure 11) and screws with a diameter 4 mm,

• attach the router on DIN rail EN 60715 with the included clip BB-SBD25.
  The router meets EN 61439-1:2011 requirements/certifications for low-voltage switchgear and control gear assemblies. These environments are described as:

• 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 the 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.

**** To comply with the EN 61439-1:2011 specification, follow these instructions:

• 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 separate from the switchboard it is necessary to fit a lightning conductor.

• When mounting a router on sheet steel we recommend using a cable antenna.

• For all cables, we recommend binding the bunch, and for this we recommend:
  – The length of the bunch (the 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 each connector for the handling of cables,

• To ensure the 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 from the DIN rail
The DIN rail clip is suitable for a DIN rail according to EN 60715 standards only. The default position of the metal rail clip, which is used for mounting the router on a DIN rail, is shown in the following figure. When mounting the DIN rail clip, tighten the screws with max. 0.4 Nm torque.

To remove the router from the DIN rail, push the router down lightly, so the bottom part of the DIN rail clip (hitched to the DIN rail) gets out of the rail and then pull out the bottom part of the router away from the DIN rail.

5.7 Description of the Rear Panel
The rear panel contains two holders for SIM cards (SIM1, SIM2) and an RST button used to restore the default configuration followed by rebooting of the router. The picture with the rear view of the router is on figure 12. A description of the resetting procedure is described in chapter 5.8.7.
5.8 Description of the Front Panel
On the front panel is the following:

5.8.2 Power PWR/IO Connector
Panel socket 4-pin.

Table 6: Connection of PWR / IO connector

The unit has to be supplied by a power supply specified as a Limited Power Source (LPS) according to Annex Q of IEC 62368-1:2014. If the power supply/cable provided with the device is not used, always use the cables with a minimum wire size (nominal cross section) of 0.5 square mm for the power supply.
The power supply for the router must be between +9 V to +36 V DC, with current output 1 A. 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 is awakened after the power supply outage and subsequent renewal.

The PWR / IO interface is also designed for the processing of binary input and control (setting) of binary output.

Binary Input

Table 7: Characteristics of binary input

∗ The binary input status in the Shell is returned via io get bin0.

Binary Output
The binary output is open in the default configuration. The current of the binary output is limited by a resettable fuse (200 mA).
Binary inputs and output connections
Binary inputs and output connections example:

Low Power Mode
The router can be put into low power mode using a special command up. It can then be awakened by activity on binary input or using an internal timer. For more details of this command, see the application note Commands and Scripts [3]. Consumption in LPM mode may vary depending on the configuration of the router.
All metal parts are connected together with the negative pole of the power supply (common pole).
However, the router box may not be connected to the negative pole properly.

5.8.3 Antenna Connector ANT, DIV, and WiFi
The main and diversity 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 First, connect the main antenna to the router. To connect the diversity antenna, the second antenna connector DIV is used. 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 the 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 router’s front panel (see the figure below).
Recommended tightening moment is 0.9 Nm.

A diversity antenna improves the radio capability of the router at low signal strength.

5.8.4 SIM Card Reader
The SmartStart SL302 contains two readers for 3 V and 1.8 V SIM cards, which are located on the rear panel of the device. 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 APNs (Access Point Names) adjusted.
Supported type of SIM cards: Mini SIM (2FF), dimensions 25.0 x 15.0 x 0.76 mm.

Changing the SIM card:

• Always disconnect the router from the power supply before handling the SIM card.
• To remove the SIM card, use the flat end of a spudger, 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.

5.8.5 Ethernet Port ETH
The panel socket RJ45 is used for this interface. The isolation barrier of the Ethernet signal ports against the ground is 1500 V.

Table 8: Connection of Ethernet connector

The Ethernet cable plugs into the RJ45 connector labeled as ETH (see the figure below).

5.8.6 Serial Port RS232
This interface is physically connected through the DB9 Female connector.

Table 9: Connection of RS232 connector

5.8.7 Reset
When the PWR LED starts flashing on the front panel, it is possible to restore the default configuration of the router by pressing the RST button on the rear panel. After pressing this button, the default configuration will be restored and the router will reboot (after which the green LED will be on).
In order to press the RST button, it is necessary to use a narrow screwdriver or another small tool.

**** Before resetting the router, it is recommended to back up the router configuration settings (see Configuration manual) because resetting the router will return all configuration settings to their default states.

It is important to distinguish between a router reset and a reboot.

First Use

6.1 Connecting the Router Before the First Use
Before putting the router into operation it is necessary to connect all of the components that are required to run your applications. Don’t forget to insert a SIM card.

**** The router can not operate without a connected antenna, SIM card, and power supply. If the antenna is not connected, the router may be damaged.

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 ETH. The router’s behavior can be changed via the web interface. This is described in detail in the Configuration manual for SmartStart.

6.3 Configuration
** 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 a 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!

By default, configuration may be performed only by the user “root”. The default password is printed on the router’s label. 1 Change the default password as soon as possible!
**** All routers have the WebAccess/DMP client pre-installed by default. The activated client periodically uploads router identifiers and configuration to the WebAccess/DMP server.
See the configuration manual [2], chapter Basic Information -> WebAccess/DMP Configuration, for more information.
1 If the router’s label does not contain a unique password, use the password “root”.

Once the login information is entered successfully, the user will have access to the router’s web interface via the web browser.

A detailed description of the router settings in the Web interface can be found in the Configuration manual for SmartStart.

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:

• Make sure your PC’s network card is configured to obtain the IP address from the DHCP server (by default the DHCP server is running in the router).
• Connect the router to the PC via Switch.
• Connect the router to the PC, start the router first and then start the PC after the router’s initialization.

9.1 FAQ
✍ Ethernet connection fails or is not established.

• It is possible to turn auto-negotiation off and set a rate and duplex manually on the Ethernet interface of the router. Available on the “LAN Configuration” page in the router.

✍ Mobile WAN connection fails.

• Check the signal power (“Mobile WAN status” page). If the signal power is weak, you will have to use a better antenna. If the neighboring cells have similar signal
  strength, you will need to use a directional antenna. For proper operation, the signal levels have to be good.

• Try to enable automatic ping from the router, which will check the connection when there are no data running, and in the case of a failed ping, restart the connection.
  This can be done on the “Mobile WAN Configuration” page in the router in the “Check connection” section. The “Enable + bind” option is to ensure the ping goes always through the Mobile WAN network interface.

✍ Mobile WAN connection cannot be established.

• Check the “Mobile WAN Configuration” – APN, name, password, and IP address (all can be blank).

• Try to enter the SIM card PIN – verify that the SIM card has the PIN code entered.
  Available on the “Unlock SIM Card” page in the “Administration” section.

• In a private APN, it is not recommended to get the DNS settings from the operator (on the “Mobile WAN” page)

• Go to the “System Log” page in the “Status” section and observe where the error occurs.

✍ I cannot connect from the Internet to the device behind the router. I have NAT enabled.

• The device’s gateway has to be configured so it points to the router.

✍ I can’t access my Web server placed behind the router over NAT.

• The remote HTTP access to the router has to be disabled on the “NAT Configuration” page in the router. Also, enable the “Send all remaining incoming packets to default server” feature and fill in the IP address of your Web server. On the Web server, the default gateway has to be the IP address of the router.

✍ DynDNS doesn’t work.

• With private APN this will not work.
• 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.
• You can verify NAT using ping to your server with a static address and then compare it with the router’s IP address.
• You can verify a Firewall by accessing remotely the router’s Web interface.
• The operator may not provide the address of the DNS server and without the DNS server’s address, it is impossible to connect to the dyndns.org server. The following  essages will be shown in the System Log:
  – DynDNS daemon started
  – Error resolving hostname: no such file or directory
  – Connect to DynDNS server failed

✍ L2TP or IPSec isn’t established.

• Check the “System Log” page for error messages.

✍ IPSec tunnel establishes but the communication does not run.

• Probably there are bad routing rules defined in the connected devices or the default gateway.

✍ I switched the router to offline mode by SMS message, but the router is in online mode after reboot.

• SMS messages do not change the router’s configuration. They remain in effect only until the router is rebooted.

✍ Serial communication is not working.

• Verify that the router model supports serial communications. Also, verify the serial communication settings. To do so, open the router’s configuration menu via the web browser, select the appropriate “Expansion Port” from the “Configuration” part of the menu and verify the settings.

✍ Is the router Cisco compatible? Can I use the Cisco configuration?

• No, the Firmware in the router (Conel OS) is based on Linux with BusyBox. Thus the Cisco configuration cannot be used. But network connections are defined by standards so connecting the router to the Cisco or other networking devices is possible and will be compatible.

✍ FTP or SFTP does not work

• FTP will work on v2 routers only. You can use SFTP on all routers to transfer files to/from the router. If having trouble with FTP on v2 routers, make sure you have
  FTP enabled: “Configuration” section, “Services”, “FTP”. Then you can connect with any client on port 21 with name and password same as for the Web interface.
  If having trouble with SFTP, make sure you have SSH enabled: “Configuration” section, “Services”, “SSH”. Then you can connect with any client on port 22 with a name and password same as for the Web interface.

✍ How can I connect to the router’s command line? (SSH, Telnet)

• You can use SSH on all routers or Telnet on v2 routers only. SSH is enabled by default, but you can verify in the Web interface in the “Configuration” section, “Services”, “SSH”. Then connect with any SSH client on port 22 of the router. The user and password are the same as for the Web interface. Telnet on v2 routers can be enabled here: “Configuration” section, “Services”, “Telnet”.
