A serviceable and properly connected Configurator (Figure H-11) will have transmit (TRANS) and receive
(REC) LEDs pulsing alternately in unison with the transmit and receive LEDs in the Controller.
Gilbarco applications should have flickering lights in the D-Box for connected grade positions, and steady
lights where there are no grade position connections. If all connected and unconnected grade positions
have steady lights, try reversing the Configurator to D-Box cable.
