3000 Micro GC Operating Manual
3.4.2 C-Board
The Communications Board, also known as the C-board is internally mounted on
the side of 3000 Micro GC. It controls the inlet zone heater and communicates with
the D-boards and onboard computer.
3.4.3 OBC Board
The onboard computer (OBC) is internally mounted on the back of 3000 Micro GC.
It is the main processor which communicates with the C-board and the external
control system. OBC has an internal flash memory which stores 3000 Micro GC
configuration information. See Figure 3-16.

The OBC provides a RJ-45 based LAN interface. 3000 Micro GC can be connected
to a LAN network or directly to an external control system (i.e., EZ IQ software) via
a RJ-45 LAN connection.
