7.6.1.1 Port Forwarding (PPP and Ethernet Devices)
FIGURE 7-5. Firewall Rules IP Address range
If the modem’s serial PPP mode is being used or an Ethernet device (i.e.
CCFC) is being connected to, port forwarding rules specifying how to direct
incoming traffic to the device must be created. When there are multiple devices
or only specific ports need to be passed, port forwarding is used to forward
incoming traffic from the Wide Area Network (WAN) to specific IP addresses
and ports on the Local Area Network (LAN). The 4GMini/4GPlus looks at
each incoming Ethernet packet on the WAN and b y us ing the dest ination port
number, determines where it will se nd the d a ta on the private LAN.
The fields required to configure port forwarding are found on the Port Forwarding tab under the Firewall tab of the 4GMini/4GPlus user interface. In
order to implement a port forwarding rule, enter the required values, click Add Port Forwarding, then the Submit button. Port forwarding can be used in
combination with other firewall features, but carrier requests must be blocked
for port forwarding to be in effect. If using PPP mode both Port Forwarding
and Rules are required.

Power for the modem can be sourced directly from the datalogger. Connection
to the switched 12V terminal allows the user to control power to the modem
through the datalogger program. In this way, power can be conserved by
limiting the time that the modem is on. For example, the user could choose to
power on the modem only for scheduled data collections or only during certain
hours of the day. When using the switc hed 12V terminal, be sure t o allow time
for the modem to warm up and provision to the network. The required warm up
time can vary, but the recommended minimum is 3 minutes.

7.9.3 Modem Conne ction using Ethernet
In some cases it may be desirable to connect using the Ethernet
interface available on the 4GMini/4 G Plus cellular modem. To
do this, a CR1000 or CR3000 with either a NL120 Ethernet
Interface, NL116 Ethernet/Compact Flash Module, or any
datalogger using a NL2XX series device is required. A
crossover Ethernet cable is needed to connect the two devices.
Please review the literature for the specific interface for more
details.
7.10 Testing t he Cel lular Connection
After the Device Map has been configured, it is recommended
to test the cellular connection usin g the Connect screen. Click
on the appropriate station, then click the Connect button to
initiate a call to the datalogger. Be sure all connections are
complete and power is supplied to both the modem and
datalogger.
If the call is successful, the connectors at the bottom of the
screen will come together and time information from the
datalogger will be displayed the Station Date/Time field . If the
connection fails, a Communications Failure message is
displayed.

8.3 Hardware
4GMini/4GPlus Cellular Modem
L14162 - 4GMini/4GPlus Mounting Kit include s mounting hardware for
securing the modem to the environmental enclosure. The 4GMini/4GPlus
should be mounted in a position that allows easy access for the cables, so they
are not bent or constricted.
Antenna - the following antennae are available from Campbell Scientific. The
antenna(e) must be connected to the Antenna connector of the 4GMini/4GPlus.
Contact a Campbell Scientific Applic a tions Technician for help in determining
the best antenna for the intended application.
C2446 – is a dual band, 3dB omni-directional antenna for the CDMA and
GPRS digital cellular modems. This antenna is recommended for locations
where cellular coverage is strong. The C2446 includes a mount/u-bolt
assembly that allows the antenna to be mounted to a mast, crossman, or usersupplied pole (outer diameter of up to 1.5” (3.8cm)).
C2445 – 9dBd Yagi Antenna is a highe r gain ante nna that sho ul d be “aimed” at
the service provider’s antenna. The C2445 is a 800MHz antenna, which has a
bracket/u-bolt assembly for attaching the antenna to a mast or post. The
antenna comes with 10’ of cable. This antenna is recommended for fringe areas
that require a higher gain antenna.
C244 - 9dBd Yagi Ante nna is a higher gain antenna that should be “aimed” at
the service provider’s antenna. The C2445 is a 800MHz antenna, which has a
bracket/u-bolt assembly for attaching the antenna to a mast or post. The
antenna comes with 30’ of cable and surge protection. This antenna is
recommended for fringe areas that require a higher gain antenna.
L21831 – Half-wave Dipole Whip antenna is a lower gain antenna used in
transmitting short distances. It is an 8 00MHz cellular antenna that terminates in
a SMA Male connector for attachement to the mod em. This antenna is intended
for use inside the enclosure. Please note that the backplate of the enclosure is a
grounded plane. If it is interposed between the antenna and the cell tower, it
may attenuat e the strength of the transmission signal. Simply turning the
enclosure 90 to 180° on its mounting mast may solve weak transmission issues.

9. Troubleshooting
If LoggerNet/PC400W software is unable to establish a connection with the
modem:
1. Check the account information (a phone call to the provider may be
required).
2. Verify that there is coverage at the location.
3. Check the SGNL Indicator LEDs on the front of the modem.
Ensure that the modem has successful l y connected to the cellular
network.
4. Make sure the modem and datalogger have sufficient power.
5. Check the RSSI LEDs on t he front of the modem or in t he Web
Interface. If the measured signal strength is less than –110dBm no
LEDs will be illuminated. If the signal is greater than –105dBm, 1
LED will be on, - 100dBm equals 2 LEDs and any signal greater than
– 95dBm will show all 3 RSSI LEDs to be ON.
6. If using a D ynamic IP acc ount, a dyna mic domain name server
(DDNS) name that LoggerNet can reference to make the connection
will be required.
7. In the Summary tab in the System group of the modem’s configuration
28
Page 37
4GMini/4GPlus Cellular Modem
webpage, make sure Connection Status is Call in Progress or
Connected and note the WAN IP Address. This is the current IP
address for the modem (a dynamic IP address will change each time
the modem is reset). Try connecting to this IP address using
LoggerNet. If LoggerNet connects with the IP address, but not with
the modem name.domain name, then there may be a problem with the
Dynamic IP setup in the modem.

Appendix A. Example of Port
Forwarding using the Modem
In this example, the 4GMini/4GPlus and all related equipment
have been configured to allow for the simultaneous connection
of 2 dataloggers to the modem. The first datalogger, a CR200X,
is connected directly to the RS-232 port of the modem via a null
modem cable. The second datalogger, a CR1000, is networked
to the modem via an NL201 and a pair of RF401A radios. In any
such arrangement it is important to c onfigure the firewall and
port forwarding rules to ensure proper access, while maintaining
a reasonable level of protection.
This example assumes that all necessary configuration steps
were taken to provision the modem on the network in either a
Static or Dynamic IP arrangement, as well as the NL201
being configured properly with an IP address of
192.168.168.2.
Following is a diagram of the physical connection of the
applications:

A.1.1 Point to Point Protocol (PPP) Communications (optional)
In PPP mode, the modem assigns the datalogger an IP address by means of a
serial connection. This allows access to the datalogger’s IP capabilities without
requiring an Ethernet peripheral. The modem’s COM1/Data port must be used
for a PPP connection. In order for the PPP to function properly, both the
modem and datalogger need to be configured. The physical connection for PPP
communications requires the use of a null modem cable to connect the
dataloggger’s RS-232 to the modem’s RS-232 port.
