LEDs are visible to monitor the current system state. Data is transferred via an RS232 serial cable from the evaluation board to the serial port on your PC via NMEA formatted messages. Every system comes with firmware already loaded into the receiver, ready to plug and play. A 12V DC input is all that is required to power the system. Evaluation Board with Cover Removed To evaluate the performance of the system, software is provided to monitor all aspects of the system operation in real-time or by reviewing a data-logged file of a previous trip for later analysis. The graphic display shows information such as satellite tracking, strength of signal, position, velocity and time.
