CT-N816
CorNet ARCNET Diagnostic Hub 8 Port Twisted Pair
|
Description
This is an ARCNET hub with diagnostic LEDs and linking ports. The CT-N800 series of
hubs was created to fill a need for an ARCNET hub with additional diagnostic capabilities
for tracking down reconfiguration problems without resorting to the complexity and cost
of an "Intelligent Hub". These hubs are built to withstand a wide range of temperature
and power line voltage swings. The hubs maintain full output levels even when
running at maximum temperature and data traffic loads.
This stability is provided through the use of a
switching regulator in the power supply and attention
to detail in the output driver section. The switching
regulator produces less heat and withstands brownouts
better than a linear regulator. Proper thermal design
ensures that heat produced in the output drivers is
dissipated via convection air currents in any acceptable mounting position.
