Installation distance > 20mm
Vent
*
Installation attention : please reserve enough ventilation distance between decoders (>20mm),
be sure not to block the vent, or will affect lifetime of decoder for .poor heat dissipation
Connecting with green terminal or an extra amplifier will be needed when more than 32
decoders are connected or use overlong signal wire(as shown below).
Signal amplifier should not be more than 5 times continuously.
