Docking Station can't connect to Dell Latitude E7470

The only docks that work fully with this system have a Dell E-port connector.  

You can find USB-C to USB-A cables that will allow the connection of an otherwise incompatible dock, but you'll then have a glorified USB hub -- not a true docking station, as the dock will be missing much of its functionality connected this way.

Your Latitude does not have thunderbolt connection to use with a thunderbolt dock.  Considering an E-port replicator PRO3X.  It can be had for less than $20 USD with 240w power adapter included as in the reference link.

@Chino de Oro​ There's no wire/cable that I can use to connect my docking station to my Latitude?

@ejn63​ So do you recommend that I get that cable? What is it called and how will it resolve my issue? From where to where do I have to connect it?

Unless you have plans only to use USB devices (don't need the dock for monitor, etc.), the cable will not help.  See the other reply -- if you want the dock for use with a monitor, you will need an E-port docking station as Chino de Oro mentioned.

@dawoudleftu , it was not a cable, I suggest a whole docking station that was made to accommodate your Dell Latitude.  Just line up the E-port underneath the laptop and press it down on the PRO3X and the setup is done.  Run the connection from the PRO3X docking station to setup just like a desktop.  When you need to take the laptop mobile, just push eject button and take the laptop away.

See this reference link  E-port replicator PRO3X. for item information, it will cost around $20 dollars.

See this YT video for how to connect and setup https://www.youtube.com/watch?v=SrsHkYLk8zg

@ejn63​ I want to use it to connect between monitor and my laptop, is there any other simple solution or do I HAVE to get the other docking station?

You need a compatible docking station -- any Dell E-port dock will work.  

These are all old stock or used, so they are inexpensive.
