I want to connect my scanner sensor to arduino. On the internet I found only pin layouts for 10 pins connector. I don't know how to check pins using oscilloscope but I could have access to one. It has 14 pins and the only written model number on it is "CA-4B8A REV:A3" but I found that it's CE841-60111 Q8418-60043. This link shows only how it looks.
