Overview
The T24-RDC collects data from remote T24 transmitter modules and generates CSV files, custom SMS reports
and triggered reports that are delivered over the cellular GPRS network and GSM network for SMS messaging.
You can either define the active group of remote transmitter modules or allow the module to work automatically,
adding new modules as it detects them.
The main logging functionality is to collect data from the remote modules and place the results into a CSV file.
You can specify the amount of data stored in the CSV file by setting the age of data it contains.
You can also specify at what interval the CSV file is delivered to up to 3 destinations which can be an email
address, SMS phone number, FTP server, raw socket or delivered as an HTTP POST to a web server. This allows a
very flexible level of control over what data is reported and when.
For example, you may want to collect and report only 24 hours worth of data at a time or possibly collect data
over one month but still report 1 months worth of data weekly.
SMS reports can be user designed to deliver the data values from specific modules and be triggered by sending
an SMS message to the module. Up to 10 SMS reports can be designed. The remote modules can be referenced
either by channel number or data tag. These reports are always sent back to the phone that triggered the
message.
Up to 20 triggered reports can be user designed that can look for individual modules exceeding limits, reporting
errors or local events such as loss of external power and lid open, or even just at set intervals.
These alerts can deliver a custom message (that can refer to the channels and values that caused the error) to an
email address, SMS phone number, FTP server, raw socket or delivered as an HTTP POST to a web server.
A single alert can be defined to cover a range or all modules but in this case individual
values cannot be reported, just the fact that channels 1,3,4-8 have exceeded set limits etc.
SMS messaging may also be used to change or update certain user parameters of the module. i.e. You may
change a delivery destination of a report or change the interval of reporting. This saves on costly site visits for
minor operational changes.
The module has an internal Li-ion battery which can act as battery backup, or in low power mode, may power the
module for the required period of operation. An external power supply can increase the operation periods and
may be a permanent supply or batteries. The internal battery is recharged by the external power supply.
There are three operational modes: Normal, Low Power and Ultra Low Power. In normal mode incoming SMS
messages are processed as they are received and triggered reports are checked in real time. In low power mode
the whole module sleeps between captures so cannot act on incoming SMS messages or triggered reports until it
next wakes at the log interval. In Ultra Low Power mode the SMS reports and triggered reports are not actioned
until the CSV data send interval.
The RDC is a Remote Data Collection module which communicates using GSM/GPRS and therefore is bound by
the restrictions and limitations of a mobile data network. This can include but is not limited to partial or complete
loss of coverage, environmental interference or network faults.
