LED Designations
The Quad TriplePlay Serial card includes transmit and receive LEDs. The transmit
LED is leftmost when the card is in the top slot and will light while characters are
being transmitted. The receive LED is rightmost when the card is in the top slot and
will light while characters are being received.
Serial port numbers are as described by the “SER” labels as shown in the home page
