Memory - The device has 64MB of Flash Memory, 33 MB of that is allocated for Log, 27MB is for Fault, and 4MB is for Event
Using GPS - GPS system can be used to adjust clock of the device, therefore all devices which are positioned in different geographical places have clocks synchronized by global time with accuracy of better than 1ms.
Standalone - The device works independent of other devices and peripheral PC. As mentioned before each device has a Flash Memory in which, data of logs, events, faults, and other needed data is stored. Whenever PC is on, the stored data can be read and saved by the PC.
Software Upgrade - System Software Upgrade can be done without making any changes in the hardware. The new software can be uploaded from PC and via a communication link
