1.4 USE OF CELLULAR NETWORKS – IMPORTANT NOTES
Availability of SMS
Most Pegasus2 models include the ability to communicate to a server via use of the
cellular data network. This is usually via the regular data network (which gives internet
access). Alternatively, the SMS (Short Message Service) messaging can be used; in most
cases this will be as a fall-back if the logger is temporarily unable to access the regular
data network. If configured for SMS use, the logger uses the available 2G network.
Important: 2G (GPRS) services, which carry the SMS messaging system, are slowly
being turned off around the globe. Once 2G is switched off, the SMS
services available within the logger will no longer be able to function.
Unless deactivated in the logger settings, the logger will continue to try,
wasting battery power. Therefore, check with your cellular network
operator for their switch off date before setting the logger to use the SMS
backup service or any other feature requiring SMS use.
To deactivate the use of the SMS system, any related SMS settings must be removed
(switched off or deleted). Refer to the IDT User Guide for details of SMS settings.
Any modified settings must be saved to the logger.
Note: For use of SMS services, both the logger and the cellular network provider must
support SMS. In addition, the SIM card fitted inside the logger must support SMS
use. (Check with your SIM supplier if required).
Logger identity when using SMS
When using the cellular data network, the logger identity is included with the data
within the message. However, when using the SMS system, the identity is the calling
number (from the SIM card). Thus, when using any SMS services, these two numbers
(IDT setting of logger telephone number and SIM telephone number) must match.
1.5 VIEWING DATA
To view Pegasus2 data remotely, a viewing tool (website) is used. Various websites are
available.
• Pegasus2 is most frequently used with the PressView website, which is for use
with pressure control applications.
• Data produced by the built-in logger can also be seen on the DataView website.
Data from the Pegasus2 unit can also be viewed locally using IDT during a site visit.
Refer to the training materials available for your viewing tool and also the IDT user-
guide for further information.
1.6 IDT – SOFTWARE TOOL (FOR DEVICE PROGRAMMING AND TESTS)
A software tool, known as “IDT” (Installation and Diagnostic Tool), provides a user-
interface to the Pegasus2. It can be used for checking or making adjustments to the
setup of the unit, for assisting with installation of the system, and also for testing the
operation of the unit within its installed site.
