Name
This indicator is off when A1 and B1 of the encoder are
disconnected; it blinks when C1 and D1 of the encoder are
indicator
disconnected; and it is on the encoder signals are normal.
Power This indicator is on after the control board feeds power to the
indicator PG card.
This indicator is on when the expansion card is establishing
a connection with the control board; it blinks periodically
after the expansion 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 expansion card is disconnected from
the control board.
