LED functions

The green LED is on whenever there is power to the device. A constant blinking (2Hz) of the green LED indicates that the power supply is out of range. The green LED may be disabled by a mode bit (see command #40)

The amber or red LED flashes when there is traffic packet on the RS232 line. It also stays on while the device is moving. When the potentiometer is turned, the amber or red LED will blink at a rate that is proportional to how far the potentiometer is turned. The farther the knob is turned away from center detent, the faster the LED will blink. If the device reaches either the home or the away limit while under manual control, the LED will blink slowly to indicate that the device cannot move any farther.
