LOW COST RTU SOLUTION WITH THE SUPERIOR INTELLIGENCE OF THE SMARTMAX
HSPA SMART MODEM WITH SDI-12.
SDI-12 is a simple ASCII-based protocol and communications standard, used by a multitude of
environmental measurement and monitoring equipment types, including rain gauges, water quality
sensors and pressure sensors.
The Smartmax with SDI-12 functionality is a high performance, self-contained, data logger suitable for
measuring a number of sensor types. This option coupled with the intelligence of the Smartmax wireless
capabilities provides a low-cost alternative for an expensive RTU solution measuring a limited number
of sensors.
