100 • Technical Specifications Teledyne Lumenera Lt Series
Samtec connector-cable assembly SFSD-05-28-H-03.00-SR with retention clips
.050 Tiger Eye™ Double Row Discrete Wire Cable Assembly, Socket
6.5.4 Bi-directional I/O DC Specifications
Lt-Ux0x-xxxxx and Lt-Ux1x-xxxxx only
GPO Operating Characteristics (GPIO2 & GPIO3 as outputs)
LOW value: 0.0 to 0.6 V HIGH value: 2.65 to 3.3 V Typical output current: 24 mA
GPI Operating Characteristics (GPIO2 & GPIO3 as inputs)
LOW input voltages: 0.0 to 0.8 V HIGH input voltages: 2.0 to 5.0 V
6.5.5 Optically-Isolated Input Specifications
The optically-isolated input pins are designed to operate from 3.3 V to 24 V at a typical current of
20 mA (maximum 50 mA, minimum 5 mA @ 3.3 V). Greater input voltages are supported with use
of an external voltage dropping resistor. The opto-isolated internal current limiting resistor is
800 Ω.
•
Lt-Ux0x-xxxxx / Lt-Ux1x-xxxxx – The external signal is applied to the GPI1+/Opto In input
and the GPI1–/Opto Ground is connected to ground. When the external signal goes positive
relative to ground and current flows through the input pins, the camera receives an active high
trigger signal.
• Lt-Ux0x-xxxxx models only – The external signal is applied to the (–) input and the (+) is
connected to a positive voltage (Vcc). When the external signal goes negative relative to Vcc
and current flows through the GPI input pins, the camera receives an active high trigger signal.
•
Lt-Ux1x-xxxxx models only allow for active high configuration.
