Functional Description
The 2000NET is designed to allow remote control and monitoring of
modules in a 2000 Series Kameleon frame. It communicates to remote
devices through an Ethernet connection. It communicates with modules in
the frame via the frame bus. It also performs the error monitoring of the
power supplies, modules, temperature and fans. It does error reporting
through on board LEDs, the front panel LEDs, and the frame alarm relay
(via a DB9 connector on the back of the frame).
Refer to the block diagram in Figure 41 while reading the following func-
