Section 1 . Introduction

1.2.6Other Key Features

∙An internal lithium battery which retains configuration information (estimated life 10 years)

∙A built-in system watchdog which will reset the processor in the event of a crash caused by transients, etc.

∙A multi-tasking operating system allowing concurrent transmission and receipt of data on all ports. This allows the receipt and processing of data from all four serial ports concurrently at 9600 baud.

∙A built-in status LED to give an indication of system function on power- up.
