INTERFACE SIGNALS
Binary signals
Binary code is a standardized way to control outputs that are used for floor displays. The benefit is that you
use less output signals to control multiple signals. I.e. there are only 3 signals needed to display 7 floors, 4
signals to display 15 floors, 5 signals to display 31 floors etc.
Example:
Floor Code Floor Code
0 0000 8 1000
1 0001 9 1001
2 0010 10 1010
3 0011 11 1011
4 0100 12 1100
5 0101 13 1101
6 0110 14 1110
7 0111 15 1111
Example:
Floor Code Floor Code
0 0000 8 1100
1 0001 9 1101
2 0011 10 1111
3 0010 11 1110
4 0110 12 1010
5 0111 13 1011
6 0101 14 1001
7 0100 15 1000
GRAY CODE SIGNALS
Gray code is a slightly more rare way to control floor displays.
It is often used on older controllers.
DECIMAL SIGNALS (ONE-FLOOR-PER-PIN)
The old way to control floor displays are called Decimal or one-floor-per-pin.
One output signal is needed for every floor, i.e. 8 outputs for 8 floors.
Example:
Floor Code
1 10000000
2 01000000
3 00100000
4 00010000
5 00001000
6 00000100
7 00000010
8 00000001
