Our capabilities with analog landline
modems, cellular modems, and off the shelf remote
data loggers, are perfectly aligned with remote
application requirements, which need to monitor
field data over long distances especially in real
Most embedded systems modems and data loggers
continue to use serial RS232 communications. RS232
is a very simple low complexity standard, which
has been used in modem communications for decades.
It is ideal for micro controller slave applications
due to the low resources required.
Of course, some personal computer modems have
migrated to the Universal Serial Bus (USB) standard.
There are several solutions available to implement
USB in slave micro controllers using of the shelf
programmable devices. However we have not yet
come across a viable USB modem solution to be
used in an embedded or remote system.
Remote data acquisition services can be implemented
in different ways. Important considerations include
the amount of data that needs to be transferred
and whether it needs to happen in real time. For
example when traking a vehicle using a GPS modem
There are many platforms available for remote
data storage. Low powered micro processing modules
with built in serial memory can operate for a
long time while performing data collection and
storage. Higher power requirements needed for
modems, can be provided with long life batteries
and solar cells. The remote data logger device
can monitor and store data until ready to send
back to a base station, bringing the modem out
of sleep mode. Microprocessors can be put into
sleep mode to preserve power, periodically waking
up to take measurements or transmit data.
There are all sorts of possibilities when it
comes to customized-solutions for remote data
collection. Much depends on the application itself
and the geography where used. Even remote desert
and mountain areas can use satellite services,
although there is a time lag measured in minutes.
For the closer in systems, we increase our options
by using RF serial data platforms, landline modems,
and cellular modems.
In house data can be tracked using internet connections.
For example products that need to be tracked using
radio frequency identification technology (RFID).

We are available on a hourly basis to give you
pointers as to which systems are out there and
which ones you might use for your application.
We may already post answers to those questions
