Synchronized image capture can be performed between two or more PL-B cameras, with simple cabling. See the diagram below to view the cabling diagram and refer to the hardware specs regarding the machine vision connector, if needed. In essence, the programmable output from one camera is used as an input trigger into itself, and one or more other cameras.
The PL-B cameras have a 9-pin Micro-D connector in the back for external control. This diagram shows the pin-outs on that connector, and how they can be connected together to make synchronised capture work. While it is best to use a custom cable, with Micro-D connectors for any production system, it is possible during prototyping to test this scenario using a few simple pieces of wire inserted into the correct pins.
