Function
This indicator is steadily ON in the presence of primary DC or AC
power. If your unit has an optional battery, this indicator will blink
while being powered by the battery (discharge mode).
Indicates data input to the DATA I/O Port.
Indicates data output from the DATA I/O Port.
Indicates a true RTS input to Pin 4 of the RS232 connector when
on.
Indicates a true CTS output from Pin 5 of the RS232 connector,
when on.
Indicates data input to Pin 2 of the Expansion Port.
Indicates data output from Pin 3 of the Expansion Port
Indicates data being transmitted via the TX1 optical port.
Indicates data being received by the RX1 optical port
Indicates data being transmitted via the TX2 optical port.
Indicate data being received by the RX2 optical port.
When on, indicates that the RX1 optical input port is currently
selected by the Priority Select circuitry.
When on, indicates that the RX2 optical input port is currently
selected by the Priority Select circuitry.
Indicates an electrical anti-streaming timeout, except when the
unit is in Master Fault Tolerant mode. In MFT mode, it indicates a
break in one of the rings.
When this light is on, the battery charger is operating at or near
its 150 mA max. current. This will occur when a battery is being
freshly charged after a power outage when the battery is nearly
totally discharged.
Indicates that it is properly receiving a "BERT" signal transmitted
by another unit (usually the master).
