C™ communications bus
typically found in applications, such as personal computers
or rack mount servers. The bus connects to multiple devices
used to monitor and record the health and status of a
computer system. The PICDEM System Management Board
integrates the functions of a dedicated Real-Time Clock
(RTC), serial EEPROM, thermal management controller and
analog-to-digital converter into a single PIC microcontroller.

In conjunction with the PICkit™ Serial Analyzer (included in
the kit), communication to the emulated devices on the bus
can be managed and monitored. The PICkit Serial Analyzer
is a low-cost development tool that allows communication
between a PC and the serial protocol of the system under
test.
