The document describes the Maxon M2M HSPA Smart Modem Solution I/O Board (MA-4020) which can transform the Smartmax modem into a cost-effective mini remote terminal unit (RTU) for automating and controlling field applications. The I/O Board connects to the Smartmax via a ribbon cable and provides 6 digital inputs, 2 analog inputs, 4 digital outputs, and 1 pulse input that can be programmed via the Smartmax's web interface. It has features like DNP3/SMS configuration, I/O monitoring via web page, SDK for development, and fits into Maxon's Mini I/O enclosure for an all-in-one product.

TRANSFORM THE SMARTMAX INTO A POWERFUL
COST-EFFECTIVE MINI REMOTE TERMINAL UNIT
Turn your Smartmax M2M HSPA Smart Modem Solution into a cost-effective mini RTU with the I/O
Interface Controller. When used in conjunction with Maxon’s Smartmax Modem for data telemetry,
the I/O Interface Controller provides wide-ranging flexibility for system integrators and users for
automating and controlling innumerable field applications.
Local or remote programming of the I/O Interface Controller can be done via the Smartmax’s builtin Web Interface. The fully featured web interface includes programming of the DNP3 settings and
I/O status updates via SMS.
The SmartMax connects directly to the IO board via a ribbon connection, while the I/O controller
can be wired to collect data automatically and connect directly to sensors, meters, loggers or
process equipment.
