Using Trigger and Digital I/Os - Part 3
Please Note: This blog post is part of a series of five posts altogether.
The posts include: Part 1, Part 2, Part 3, Part 4 and Part 5.
Digital I/Os - pin header
As already mentioned in the introduction, there are two ways to access the camera’s digital I/Os: using an internal pin header or an external Hirose connector. To access the internal pin header please open the cameras backplane. You will find connectors as illustrated by the drawings below. Please assemble a cable that fits your application.
The pin header consists of 2×8 pins with a pitch of 2.00 x 2.00 mm. The cable’s pinout is in the table below.
Important: Please note that only FireWire cameras provide a power supply at Pin 3 and 4. In the case of USB cameras these pins are open.

Hi,
What are the GP_in, GP_out?
Do you plan on analog output for DC iris lenses?

Hi,
We have been using ImgSrc cameras for some time and we are facing a severe problem in the triggered mode .
Connections :
24V sensor connected via a limiting sensor to +ve of trigger and -ve is ground [ which is also the sensor ground]. the same pulse is fed to a strobe controller. After some 30,000 images or so, we get a synchronization problem- we get a totally dark image.
To over come this, we have tried out the GPIO method also - strobing via the strobe out [ open drain, pin 6 ] - we have pulled up the pin 6 to ~ 20 V via a 1k resistor and the drain is connected to the strobe source. Again everything works and the black image is reduced but we still got one in around 100,000 images.
The camera in use is : DMK 21BFO4
Please suggest a way out !

Hello Boris,
“GP” stands for General Purpose, meaning that you can use these two pins for your own purpose by programing code.
We do not have any plans for the DC iris lens control.

Dear Xiao,
I had left a comment on the problem in the triggered mode that we’re facing in this blog- did you go through it ? Is there an email address where I can address my problem ?
Thanks in advance for your help.
Rgds,
MK

Using the Trigger and Digital IOs of Imaging Source Cameras…
Among others, The Imaging Source cameras can be externally triggered and have digital in- and outputs to control external devices. In a series of blog postings on their machine vision blog, The Imaging Source gives some details about the hardware and e…
