Overview

The CS-GSM/GPRS kits feature a precongured
COM110 modem that allows data to be collected
from a remote datalogger across the GSM cell phone
network. Also included are all of the necessary cables,
interfaces, mounting brackets and an antenna to
provide an easy to use solution out of the box. All that
is needed to get the system up and running is a SIM
obtained from service provider who provides good
coverage at the intended site of operation*.

Once installed, it is then possible to collect data from
the datalogger. This may either be done using GSM
dial-up (sometimes called Circuit Switched Data
mode), in a similar way to a normal landline modem
connection or the COM110 can be congured to run
a GPRS/IP connection, where the logger can be
accessed via a TCP/IP connection.

GSM dial-up connections are generally easier to set
up and to get running, but are charged for on a time
of connection basis. Obtaining a GSM dial-up service
is however becoming more difcult to get as some
operators no longer support it, especially for access
from a landline network. GPRS communications is now
the norm but setting up a connection is slightly more
complicated. Power allowing, GPRS can generally
be left always-on and is normally charged for by data
volume not time.

*When the kit is to be used in association with Campbell Scientic’s Konect
data collection service a SIM will normally be provided as part of the
subscription package.

In either mode of operation calls can either be made from
a server, normally running Campbell Scientic’s Loggernet
package, or the datalogger can be programmed to call back
to a server. Data can also be exchanged between dataloggers
over the connection.

More advanced dataloggers, such as the CR800, CR1000
and CR3000, when running in GPRS mode can, in addition
to normal communications, serve many of the functions
normally possible over a wired IP connection which includes
sending alarms and data via ftp, http or email, serving web
pages and internet clock synchronisation.

The datalogger can also be programmed to send SMS text
messages for alarms or to send small amounts of data. More
advanced dataloggers can be programmed to respond to
text messages, e.g. to trigger changes in logging speed or
communications methods.

The COM110 modem has a low power use so in many
circumstances can be left powered on. For very low power
applications, it can be switched o at certain times of the day
using the power switch built into some dataloggers or using
an optional PSW12 solid state switch.

Three dierent kits are available from Campbell Scientic
diering mainly in the interface provided. Details are
provided below. These are all precongured with settings
which will allow GSM dial-up use. The modems and the
datalogger can easily be recongured with a conguration
cable using a PC software tool called the Mobile Data
Assistant which can be downloaded from our website.

Kits available:

All kits include a modem, mounting bracket, logger connection
cables and the GSM-ANT2 antenna and cabling (see below). All
of the kits can be congured for either GSM dial-up or GPRS use
using the Mobile Data Assistant package.

CS-GSM/GPRS-RS232 kit: this is the lowest cost package and
includes a special null-modem cable for connection to the
RS232 port of the datalogger. This kit also includes a modem
programming cable.

CS-GSM kit: is a mid-priced package and includes the SC-WMI
interface for connection of the module to the CS I/O port of
the datalogger (not the CR200 series). This leaves the RS232
port of the logger free for servicing during site visits. The

SC-WMI is normally limited to baud rates below 38400 baud,
so cannot achieve the maximum throughput possible over a
GPRS connection. It is most commonly used for GSM dial-up
applications. Note: the SC-WMI should not be used where other
devices also need to be connected to the CS I/O port, e.g. the
SC115, CR1000KD, MD485 or RF416.

CS-GPRS kit: includes the SC105 SDC interface which supports
baud rates up to the maximum supported by the datalogger
and can also be used in parallel with other devices on the CS I/O
port. As this connects to the CS I/O port it leaves the RS232 free
for other uses. This kit includes a modem programming cable.

Optional extras:

Part Number 010286 COM110 Programming Cable allows direct
connection of the COM110 modem to a PC serial port.

This is normally only needed for reconguration of the modem. This
cable is supplied in some kits (see above).

Part Number 009545 PSW12 Power Switch can be used to switch 12V
power to the COM110 module, controlled by a datalogger control
port. This switch can be used to turn o power to the COM110
modem where system power consumption must be kept to an
absolute minimum. In such an application, the datalogger might only
turn on the module for 5 minutes per hour.

These packages do not include airtime contracts and SIM cards. The
end user needs to source the best contract suited to their needs
making sure that the network chosen will support the required
method of communications now and for the forseeable future. Note
that GSM dial-up access, is not supported on all networks. For the
GPRS use it is recommended you read a copy of the manual before
purchase of an airtime contract, as this discusses dierent options for
GPRS access which may require nding a specialist airtime supplier.

Antenna

The standard CS-GSM kits include the GSM-ANT2 antenna that is a
cost-eective, 0dBd, omnidirectional antenna as shown below. This can
be mounted on vertical poles from 30-54 mm in diameter, or it can be
wall mounted. It is tted with 5m of cable allowing the antenna to be
mounted as high as possible to achieve best signal reception.

For installations on remote sites with poor reception we can also
supply directional YAGI antennae of
10 dBd gain, tted with 10m of cable,
as shown below. These can only be
used on xed installation where the
bearing to the nearest cell station is
known. As they need aligning, setup
is more complicated. Please contact
Campbell Scientic for ordering
details as a specic model of antenna
is needed for dierent networks.

We can also supply specialist antenna
for installations requiring discrete or
compact antenna.

Mobile Data Assistant

The Mobile Data Assistant (MDA) is a free utility designed to
allow customers to congure Campbell Scientic (Europe)
GPRS and GSM packages that include a COM110 modem. The
MDA provides setup and diagnostic information and uses a
wizard style interface to accept the users requirements and
gather settings. Where applicable it also gives the option to
program any corresponding datalogger settings too. It can

also be used by Konect subscribers to program their COM110
modems for GPRS and GRPS Call-back.

The mobile data assistant package runs on most Windows PC
platforms (XP SP3 and above).

Specications

Input Power Supply Requirements:
5-32V DC at an average maximum current of 400mA (peak

2.5 amps @ 5.5V)
System Power Consumption:

Typical: (modem only) 5mA in `standby’ mode (GSM)

<400mA on-line, transmitting
~ 20-30 mA when online in GPRS mode.

Communication:

Modem serial port speed: Typically set at 9600 baud with
Campbell Scientic dataloggers (in GSM mode). Can be set up
to 115 kbaud if the datalogger supports it.

Data throughput rate (from the modem): typically a maximum
of 960 bytes per second in GSM mode. Rates can be up to 4000
bytes per second in GPRS mode, but this is signal strength and
network dependent.

Physical: (module only)

Operating Temperature: -30°C to +75°C

Humidity: Up to 90%, non-condensing
Size: 88 x 60 x 26 mm
