Genie HM Series-GigE Vision Camera Technical Specifications • 115
Genie Signal Electrical Details
• Power Supply (pin 2): +12V DC nominal at 0.6 Amp minimum.
Operating tolerance: 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.
• See "
Input Controls via Sapera LT or GigE Vision Compliant Applications" on page 57.
The opto-coupler is typically a Fairchild HMHA281 with the following characteristics.
