4.5 Traffic Light Option
The LaserLight 4-SG remote display also comes with a traffic light option which uses 4'' display digits in the 6'' enclosure.
The traffic light is factory configured to be controlled with serial commands but can be controlled by using dry contact switches:
one switch or two switches ( Section 3.7 on page 20 ). The following photo illustrates the location of the traffic light board and the
wiring for it. Table 4-3 illustrates the wiring from the traffic light board to J1 on the LaserLight CPU board.
