Installation and configuration of the NWL-12 Series Router
Powering the router
The NWL-12 Series Router can be powered in one of three ways:
1. Power over Ethernet (802.3af PoE) (available on the NWL-12-01 only)
2. DC power input via 6-pin connector (8-40V DC)
3. DC power input via field terminated power source (8-40V DC)
The green power LED on the router lights up when a power source is connected.
Power over Ethernet (802.3af PoE) (available on the NWL-12-01 only)
Power over Ethernet (PoE) is a method of connecting network devices through Ethernet cable where power and data are passed along a single cable. This may be a desirable method of powering the device if PoE is available, or if it’s most convenient in the desired installation environment to only have a single cable running to the NWL-12 Series Router.
There are 5 power classes defined in the IEEE 802.3-2005 standard, of which the NWL-12 Series Router is a class 3 device.

Table 7 - PoE power classes
To use PoE to power the NWL-12 Series Router, simply connect your router to a PoE injector or PoE network switch using the bundled yellow Ethernet cable 8P8C.
DC power via 6-pin connector
The DC input jack can accept power from a separately sold DC power supply. Both a standard temperature range DC power supply and an extended temperature range DC power supply are available to purchase as accessories.
To power the device via DC Power via the 6-pin connector, remove the attached green terminal block from your router and connect the external DC power supply to the router’s green DC power jack.
DC power via field terminated power source
If an existing 8-40V DC power supply is available, you can insert the wires into the supplied terminal block to power your router. Use a No. 3 flathead screwdriver to tighten the terminal block screws and secure the power wires, making sure the polarity of the wires are correctly matched, as illustrated below.

Failover power support (NWL-12-01 only)
The NWL-12 Series Router includes support for connection of two power sources at the same time. When a PoE Ethernet cable is connected and DC power is also supplied to the DC input jack of the router, the router will source power exclusively from the PoE source. In the event that power from the PoE cable is lost, the router will automatically switch to source power from the DC input jack, without affecting the router’s operation. When PoE power is restored, the router automatically switches back to receive power from the PoE input source.
Viewing power source information
You can view the current power input mode in the Advanced status section of the device’s web user interface. This is useful for remotely monitoring the device. You can also use the Software Development Kit to access this information for advanced purposes (e.g. configuring SMS alerts to inform you of the power status of the router).
To view the router’s power source information, log in to the router and expand the Advanced status box on the status page. See the Status section of this manual for more information on the status page.

Table 13 - Data connection item details
Connecting to the mobile broadband network
The router supports the configuration of up to six APN profiles; these profiles allow you to configure the settings that the router will use to connect to the 2G/3G network and switch easily between different connection settings.
For advanced networking purposes, you may activate a maximum of two profiles simultaneously (dependant on network support). When activating two connection profiles, you should avoid selecting two profiles with the same APN as this can cause only one profile to connect. Similarly, activating two profiles which are both configured to automatically determine an APN can cause a conflict and result in neither profile establishing a connection. We recommend that the two active connection profiles have differing, manually configured APNs to avoid connection issues and ensure smooth operation.
Manually configuring a connection profile
To manually configure a connection profile:
1. Click the Edit button corresponding to the Profile that you wish to modify. The data connection profile settings page is
displayed.

3. In the Profile name field, enter a name for the profile. This name is only used to identify the profile on the router.
4. Ensure that the Automatic APN selection toggle key is set to off. If it is not, click it to toggle it to the off position.
5. In the APN field, enter the APN Name (Access Point Name) and if required, use the Username and Password fields to
enter your login credentials.
6. Next to Authentication type, select either CHAP or PAP depending on the type of authentication used by your provider.
7. The Reconnect delay field specifies the number of seconds to wait between connection attempts. The default setting of 30
seconds is sufficient in most cases but you may modify it to wait up to 65535 seconds if you wish.
8. The Reconnect retries field specifies the number of times to attempt a network connection if the router fails to establish a
connection. It is set to 0 by default which causes the router to attempt to reconnect indefinitely.
9. The Metric value is used by router to prioritise routes (if multiple are available) and is set to 20 by default. This value is
sufficient in most cases but you may modify it if you are aware of the effect your changes will have on the service.
10. The MTU field allows you to modify the Maximum Transmission Unit used on the connection. Do not change this unless
instructed to by your carrier.
11. Use the NAT Masquerading toggle key to turn NAT Masquerading on or off. NAT masquerading, also known simply as
NAT is a common routing feature which allows multiple LAN devices to appear as a single WAN IP via network address translation. In this mode, the router modifies network traffic sent and received to inform remote computers on the internet
that packets originating from a machine behind the router actually originated from the WAN IP address of the router’s
internal NAT IP address. This may be disabled if a framed route configuration is required and local devices require WAN IP addresses.

12. For advanced networking such as using dual simultaneous PDP contexts, you may wish to configure a particular profile to
route only certain traffic via that profile by configuring a custom address and mask of traffic to send via that profile. To do this, in the Profile routing settings section, enter the Network address and Network mask of the remote network. If you do not want to use this feature, or are unsure, please leave these fields blank, which will not designate any particular traffic to be routed via this profile. For more information on configuring Profile routing settings, see the Setting a default gateway
with two active connection profiles example.
13. Click the Save button when you have finished entering the profile details.
Confirming a successful connection
After configuring the packet data session, and ensuring that it is enabled, click on the Status menu item at the top of the page to return to the Status page. When there is a mobile broadband connection, the WWAN section is expanded showing the details of the connection and the Status field displays Connected. To see details on the connected session, you can click the Show data usage button.

Connect on Demand
The connect on demand feature keeps the Packet Data Protocol (PDP) context deactivated by default while making it appear to locally connected devices that the router has a permanent connection to the mobile broadband network. When a packet of interest arrives or an SMS wake-up command is received, the router attempts to establish a mobile broadband data connection. When the data connection is established, the router monitors traffic and terminates the link when it is idle.
Note: When interesting packets arrive, the recovery time for the wireless WAN connection is approximately 20-30 seconds.
Configuring Connect on Demand
To configure Connect on demand:
1. Click the Networking menu item from the top menu bar.
2. On the Connect on demand page, click the Connect on demand toggle key so that it is ON. Extra options appear. See the
following sub-sections for further instructions.

Setting the router to dial a connection when traffic is detected on specific ports
In some situations, you may wish to have the internet connection disabled except at times when outbound traffic to a particular external host’s port or group of ports is sent to the router. To use this feature, click Enable dial port filter and enter the port number or list of port numbers separated by commas. When you select this option, all outbound ICMP/TCP/UDP packets to any remote host on the specified port(s) will trigger the connection to dial. Note that when this feature is enabled, the options to ignore specific packet types are not available.
Figure 24 – Connect on demand - Data activity trigger ed connection
You can allow Microsoft network awareness (NCSI) traffic through but if you prefer that they do not trigger the connection, click the Ignore Microsoft network awareness (NCSI) traffic toggle key to set it to ON.
Figure 25 - Connect on demand - Ignore NCSI traffic
Excluding certain packet types from triggering the connection to dial
Depending on your environment, you might prefer to exclude certain types of traffic passing through the router from triggering the data connection. You can tell the router to ignore outbound TCP, UDP or ICMP packets. When any of these options are checked the router will not dial a connection when that type of outbound destined data packet reaches the router from a locally connected device.
Figure 26 – Connect on demand - Excluding IP protocols
Excluding certain application types from triggering the connection to dial
Some devices may generate general traffic as a part of normal operation which you may not want to trigger the data connection. You can set the router to ignore Domain Name System (DNS), Network Time Protocol (NTP) or Microsoft network awareness (NCSI) traffic from devices behind the router. When you check the box for these options, it tells the router to ignore the request from that application type and will not dial a connection when this data type is received.

Setting timers for connection and disconnection
The router has a number of timer settings which let you determine when a connection is dialled and when it is disconnected.
Figure 28 – Connect on demand - Connect and discon nect timers
OPTION
DESCRIPTION
On data activity, stay online for at least
When traffic as per the configured settings above appear, the router will either continue to stay online, or dial a connection and will not disconnect it for the specified time period (min. 1 minute, max. 1 hour). This timer is continuously reset throughout the duration of a dial-up session, whenever data activity is detected matching the rules above.
After connecting, stay online for at least
This timer configures the router to not hang-up the connection for the specified time period after initially dialling the connection. This setting cannot be less than the keep online period above. This timer affects the connection only once per dial up session, at the beginning of the session.
After hanging up, don’t redial for
After a connection has been disconnected, you can tell the router to rest for a period of time before re-dialling.
Disconnect regardless of traffic after
Forces the router to disconnect the connection regardless of the traffic passing through it. The default setting is
never
.
Connect regularly, every / Randomise connect frequency by up to
If you want to have the router dial a connection at regular intervals, use Connect regularly, every to specify the interval between dials. Setting this to
never
effectively disables this option.
The router also features the ability to randomise the time at which the first dial action is performed. This is useful in situations such as where you have numerous routers in an area where a power outage has occurred. Setting a random dial time helps to reduce network congestion when all the routers are powered on so they do not all try to connect simultaneously.
When Connect regularly, every is set to at least 2 minutes, you are able to configure the router to randomise the time it begins to dial. The randomised dial timer only affects the initial dial after the unit powers on or after the settings are saved. For example, if you configure the router to dial every 2 minutes with a randomised dial starting time of 1 minute, the router waits for the Connect regularly, every time (2 minutes) and then randomly selects a time less than or equal to the Randomise connect frequency by up to time (1 minute). After the randomly selected time has elapsed, the router dials the connection. After the first dial, the router dials the connection every 2 minutes, ignoring the Randomise connect frequency by up to time.

Verbose mode
The router provides the option of logging all the data activity which matches the settings for the Connect on demand feature for advanced troubleshooting purposes. To enable the logging of the Connect on demand feature, click the Enable verbose mode toggle key to switch it ON. See the System log section for more information.
