If a multi-drop unit is operating in Local Unit Configuration mode, the
function of the remaining LEDs is indicated by the blue TERMINAL
labels ( TX , RX , RTS , CTS , DSR , DCD , and DTR ). These LEDs
reflect the state of the active terminal port's EIA-232 lines. If one of
these LEDs is illuminated, this indicates that positive voltage is
detected on the respective signal.
If a multi-drop unit is not operating in Local Unit Configuration mode,
the function of the LEDs is indicated by the white COMPOSITE labels
( TX , RX , DSR , CTS , and DCD ). The LEDs reflect the state of the
EIA-232 line for the composite port. If one of these LEDs is
illuminated, this indicates that positive voltage is detected on the
respective signal.
