connection - Need help identifying some cable connectors and their use case


Answer



1 is micro usb b, or mini usb b. https://www.cablestogo.com/learning/connector-guides/usb


2 I have a feeling it might of been for a 'fax printer' combined type unit. So the RJ-11 would go to a phone line, giving a printer (with serial connectivity if it needed a modem) phone capability.


3 - yes, extension cord, for things that are far away ;)


4 - the added pins are likely ground pins - so they can all terminate to the same point.


5 - That's not VGA, it's 9 Pin DSUB. It looks like it may of been for connecting to a printer, or some other kind of embedded device, but this is always going to be guess work.


6 - As answered in chat by Journey Man Geek, that is https://en.wikipedia.org/wiki/DMS-59. So yes, 2 monitors to a single port on a graphics card.


This is also a great resource for identifying ports: https://removeandreplace.com/2013/04/13/computer-ports-learn-the-name-and-location-of-the-connections-on-your-desktop-computer-or-laptop/
