Genie Signal Electrical Details
•
Power Supply (pin 2)
: +12V DC nominal.
Operating tol10% to –10%.
Over voltage and reverse voltage protection circuit built in. The protection circuit is reset by shutting down or
disconnecting the power supply.
•
The
12-pin Hirose
male connector shell and cable shield should connect to the supply earth ground to improve
EMI shielding.
