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.
