Genie Signal Electrical Details
Power Supply (pin 2)
: +12V DC nominal at 0.5 Amp minimum.
(see Camera Performance Specifications)
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 and ESD shielding.
External Inputs
Opto-coupled (2V to 12V, 2mA minimum) with internal current limit.
RS422 or TTL signal type (see figures below).
24 Volt signals supported with additional external current limiting (see figure below).
Used as trigger or integration control.
External signal polarity selected via configuration parameter.
User programmable debounce time from 1 to 255µs.
