AUI LED BNC DIS 83
O AUI LED INDICATOR This output when the 82595TX is used for
as a TPE AUI solution will turn on an LED when the 82595TX is
actively interfaced to its AUI serial port When the 82595TX is used
as a BNC AUI solution this output becomes the BNC DIS output
which can be used to power down the BNC Transceiver section (the
Transceiver and the DC to DC Converter) of the solution when the
BNC port is unconnected
LILED
86
O LINK INTEGRITY LED Normally on (low) ouput which indicates a
good link integrity status when the 82595TX is connected to an
active TPE port This output will remain on when the Link Integrity
function has been disabled It turns off (driven high) when Link
Integrity fails or when the 82595TX is actively interfaced to an AUI
port The minimum off time is 100 ms
ACTLED
85
O LINK ACTIVITY LED Normally off (high) output turns on to indicate
activity for transmission reception or collision Flashes at a rate
dependent on the level of activity on the link
POLED
84
O POLARITY LED If the 82595TX detects that the receive TPE wires
are reversed POLED will turn on (low) to indicate the fault POLED
remains on even if automatic polarity correction is enabled and the
82595TX has automatically corrected for the reversed wires
