/* Ovladaci panel pro anteny SALA. 
Piny 22-29 jsou LED pro tlacitka.
Piny 30-37 kombinuji rele do pozadovanych smeru.

TABULKA PREPINANI:
NORTHWEST: Sepnout North_B & South_A
NORTHEAST: Sepnout East_B & West_A
SOUTHEAST: Sepnout South_B & North_A
SOUTHWEST: Sepnout West_B & East_A
NORTH: Sepnout North_B & East_B & South_A & West_A
EAST: Sepnout South_B & East_B & North_A & West_A
SOUTH: Sepnout South_B & West_B & North_A & East_A
WEST: Sepnout North_B & West_B & South_A & East_A
