SmaRT designs provide smart features, and that is what we have focused on doing throughout the product line, with the use of LEDs and displays for operator feedback and system diagnostics. On most all of the products you will find basic diagnostics via LEDs providing information, such as data sent and data received, as well as LOW battery and error indications. These functions allow the user to identify the system’s basic functional state. Above and beyond, we offer options for character displays and additional LED indications for giving the operators either machine’s diagnostics, functional limits, and/or general warnings. We believe in providing these high-end features while maintaining a level of affordability.
