2. Pre-installation

TIP:
Check www.campbellsci.com to ensure you are using the latest data logger support software
and data logger operating system (OS).

Updating the OS during system setup and testing, or onsite is recommended. Sending an OS
to a remote data logger will interrupt the data logger program. If you have questions, contact
Campbell Scientific for assistance (https://www.campbellsci.com/support).

2.1 Establish cellular service

For better security, we recommend using Konect PakBus® Router with a private dynamic IP
address. This method allows only incoming PakBus communication. No other incoming
communication is supported. However, all forms of outbound communication from the data
logger are supported, including but not limited to PakBus, email, and ftp.

A public static IP address can also be used. This provides more incoming communication
functionality, but is less secure and more vulnerable to unsolicited traffic.

NOTE:
A public static IP account must be used when the module is set up in serial server mode.
Private dynamic IP accounts do not support the serial server mode.

2.1.1 Campbell Scientific cellular data service

Campbell Scientific can provide subscriptions to cellular service through Verizon, AT&T,
T-Mobile, Vodafone, Telstra, and over 600 other providers worldwide. When this cellular service
is purchased with the module, the module will come pre-provisioned with the required SIM card
and APN. If you have already purchased the CELL200 series, call Campbell Scientific to set up
service.

2.1.2 Other service providers

While using Campbell Scientific is the simplest way to obtain cellular data service for your
module, you can go directly to a provider. For more information on obtaining service directly
from Verizon and AT&T, see Verizon Wireless and AT&T (p. 85).

CELL200-Series 4G LTE Cellular Module 2

TIP:
Prepaid cellular data plans may experience service slow downs when data limits are reached.
If file transfer from a cellular-connected data logger works initially, but later has problems,
check for data overage on the cellular plan.

This does not apply to Campbell Scientific cellular data services.

2.2 Install the SIM card

NOTE:
If you purchased cellular service from Campbell Scientific with the module, it will come with
the SIM (Subscriber Identity Module) card already installed. Proceed to Konect PakBus Router

setup (p. 4)

The CELL200 series requires a Micro-SIM (3FF) (6 position / contacts); a smartcard that securely
stores the key identifying a mobile subscriber. You should only need to install the SIM once in
the life of the module.

To install the SIM card:

1. Remove the SIM card cover.

2. Note the location of the notched corner for correct alignment. The gold contact points of
the SIM face down when inserting the SIM card as shown in the following figure. Gently
slide the card into the slot until it stops and locks into place. To eject the SIM card, press it
in slightly and release.

3. Replace the SIM card cover.

2.3 Konect PakBus Router setup

For better security, we recommend using Konect PakBus® Router with a private dynamic IP
address. This method allows only incoming PakBus communication. No other incoming
communication is supported. However, all forms of outbound communication from the data
logger are supported, including but not limited to PakBus, email, and ftp. Complete the steps in
the following two sections.

2.3.1 Get started

You will need the Konect PakBus Router redemption code that came on a card with the CELL200
series.

CELL200-Series 4G LTE Cellular Module 4

Open a web browser and go to www.konectgds.com.

First-time users need to create a free account. After you submit your information, you will receive
two emails up to five minutes apart. One email will contain a Passport ID and the other your
Password. If emails are not received, check your email junk folder.

2.3.2 Set up Konect PakBus Router

1. Sign in to www.konectgds.com using your Passport ID and Password found in the two
received emails. Once logged in, you will be at the Welcome page.

CELL200-Series 4G LTE Cellular Module 5

2.

Click devices and services on the command bar to the left and select Redeem PakBus
Router Code. Enter your complimentary Router Code found on the included card with your
cellular-enabled device and click Submit.

3. The next screen shows the assigned DNS address and Port for the router. Enter a TCP
Password and select a unique PakBus Address for your data logger.

TIP:
Make note of this information for use in later steps.

4. Click Submit.

5.

To edit settings at a later date, click devices and services on the command bar and
select Manage PakBus Routers.

NOTE:
The DNS address and Port number, assigned when your account was setup, cannot be
edited.

3. Overview

The CELL200-series modules may be configured in one of five ways, depending on the data
logger, communications type, and needs of the user.

l Integrated: The module mimics the behavior of our integrated cell modems. No settings

are configured directly in the module. All settings are configured in the attached data
logger.

l Non-integrated: The module mimics the behavior of our older cellular modems. Settings

must be configured in both the module and the data logger.

l Serial Server: In this mode, the module receives IP communications over the cellular

network and converts those to serial communications to pass on to the data logger. From
the perspective of the data logger, this is no different than a serial cable connecting it to a
computer.

NOTE:
A public static IP account must be used when the module is set up in serial server
mode. Private dynamic IP accounts do not support the serial server mode.

CELL200-Series 4G LTE Cellular Module 7

l Serial Client:Use this mode when the module is behind a cellular provider firewall and it

has a privatedynamic IP address. In serial client mode the module will connect to the
cellular network and initiate a TCP client socket connection.

l Serial Server/Client:In serial server/client mode the module connects to the cellular

network and opens a listening port. When a client connects to the listening port, the
CELL200 series will be in "Serial Server" mode, as described earlier. When no client is
connected to the listening port, the CELL200 series will be in "Serial Client" mode, as
described earlier, and all data on the active port will be sent and received through the
initiated TCP client socket connection.

Data loggers compatible with each mode are shown in the following table.

4. QuickStart (integrated mode)

NOTE:
This QuickStart describes configuring the CELL200 series in integrated mode (mimicking our
internal cell modems) with its default settings. It can also be configured in non integrated or
serial server mode.

This QuickStart section does not apply to CR3000, CR1000 and CR800-series users. See

Overview (p. 7) for more information on the different modes. See CELL200 series and data

CELL200-Series 4G LTE Cellular Module 8

logger configuration (p. 31) for more information on configuring the module in the different

modes.

The Provisioning Report received with your Cellular Data Service shows whether the module was
configured with a private dynamic or public static IP address. See FIGURE 4-1 (p. 9) for an
example of a Campbell Scientific Provisioning Report. Other cellular providers should provide
similar information.

FIGURE 4-1. Static IP provisioning report

Additionally, Campbell Scientific cellular modules configured with a public static IP address will
have two stickers on the module, as shown in FIGURE 4-2 (p. 9). One sticker will show the
module phone number and data plan. The second sticker will show the static IP address.

Campbell Scientific cellular modules configured with a private dynamic IP address will have one
sticker on the module. It will show the module phone number and data plan.

4G/3G Cellular Whip Antenna with SMA Connector: A wideband termination
antenna with SMA connector and articulating base. This antenna is intended for
short-term testing use only. It is not intended for long-term use. Campbell Scientific
recommends that customers use external antennas for the best reception and
transmission of cellular signals.

NOTE:
When antennas are located away from the CELL200 series, keep the cables as short as
possible to prevent the loss of antenna gain. Route the cables to protect them from damage
and so they will not be snagged or pulled on. Avoid binding or sharp corners in the cable
routing. Bundle and tie off excess cable. Make sure the cables are secured so their weight will
not loosen the connector from the CELL200 series over time.

TIP:
Cellular phone apps, such as OpenSignal (https://opensignal.com/), show the direction to
point an antenna to get the best signal strength.
