Hi, I am designing a PCB with multiple 2-pos DF13 connectors in it (Like 50+). at the end of the board there is a 10 pos. cable. My intent is that the user (me) connects up to 9 channels in any position I like (I have 50 possible choices). However, this board is connected to another PCB that runs on DV connector that can only read 9 channels. I wanted to know if there is a simple way to have some sort of logic IC (or maybe some other simpler way?) so that 9 channels get routed into the output of the board. Also, if there is a way for this IC to always number them in the same way (say top left is no. 1 , and go incremental row-wise or column-wise). That way I can know which channel is which and I wont have to be testing each one everytime i use a different combination of positions (out of the possible 50). Im assuming it is related to how TVs work (using a giant matrix of pixels) but this is a very small matrix of sensors that might or might not be in use. Thank you!
