PL-X board-level cameras provide a GPIO interface through an 8-pin 1.25mm Molex connector and a powered I2C interface through a 6-pin 1mm JST connector located on the power-in module. The mating connector for the GPIO interface is a Molex 51021-0800 receptacle with Molex 50079-8100 wire crimp terminals and the mating connector for the powered I2C interface is a JST SHR-06V-S-B receptacle with JST SSH-003T-P0.2 wire crimp terminals.
GPIO Interface Pinout and Description
|1||3.3V||+3.3 VDC power output||Maximum current available from this pin is 50mA. Maximum external capacitive load on this pin is 50uF.|
|3||GROUND||Logic and chassis ground||0V reference.|
|4||GPO1||General Purpose Output 1|
|5||GPO2||General Purpose Output 2|
|8||GPI||General Purpose Input|
Only GPIO with the index 3 is configured for returning a GPI status value.
Pin 4 and Pin 5 cannot be used or modified for additional I2C communication interface.
Trigger and GPI Polarity
The trigger and GPI polarity can be set to Positive or Negative. (See the Triggers and GPO Tab - Pixelink Capture or External Control Tab - Capture OEM)
With the trigger polarity set to Positive, a camera will trigger on the falling edge of the trigger signal.
With the trigger polarity set to Negative, a camera will trigger on the rising edge of the trigger signal.
Powered I2C Interface Pinout and Description
|1||VBUS||+5 VDC power output||The maximum current available from this output pin is 100mA.|
|2||GROUND||Logic and chassis ground||0V reference.|
|5|| n/c||No connection|
|6|| n/c||No connection|
Pin 3 and Pin 4 are interconnected with Pin 6 and Pin 7 of the 8-pin Molex connector. Thus, only one I2C communication interface can be used.
