This indicator is on when the extension card is
establishing a connection with the control board; it
blinks periodically after the extension card is
properly connected to the control board (the
period is 1s, on for 0.5s, and off for the other
0.5s); and it is off when the extension card is
disconnected from the control board.
This indicator is off when the encoder is
disconnected; it is on when the encoder signals
are normal; and it blinks when the encoder signals
are not stable.
This indicator is on after the control board feeds
power to the PG card.
