... The sub-system code may be selected by a press button, a slider switch or hard wired. The M3004LD generates the pattern for driving the output stage. These patterns are pulse distance coded. The pulses are infrared flashes or modulat- ed. The transmission mode is defined in conjunc- tion with the sub-system address ...
