Genie Signal Electrical Details

Power Supply (pin 2): +12V DC nominal. Operating tolerance +10% 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.

External Inputs

Opto-coupled (2V to 12V, 2mA minimum) with internal current limit.

RS422 or TTL signal type.

Used as trigger or integration control.

External signal polarity selected via configuration parameter.

User programmable debounce time from 1 to 255µs.

See "Input Controls via Sapera LT or GenICam Applications" on page 50.
