Simple Circuit Example
Figure 11 shows a simple DC circuit (a light and DC power supply) being
operated by the auxiliary relay. To make the light turn on when a vehicle is
detected on Lane1, terminals R1_COM and R1_NO (normally open) would be
used. To make the light turn off when a vehicle is detected Lane1, terminals
R1_COM and R1_NC (normally closed) would be used
.

Vehicle Approach Monitor
Configure any of the 16 GPIOs to be used as a vehicle approach monitor. The
relay closure signal to these GPIOs can be supplied by an external vehicle
detector connected to an induction loop, in the drive thru, which monitors an
approaching vehicle. A typical wiring is illustrated in Figure 12.
