If you want to simulate the Tizen Device Manager to connect your remote Device so that you can install and run your application on the remote samsung device as target without actually using Device Manager GUI, all you can do is use Samsung Development Bridge (SDB), if SDB is available on your system then open the terminal and execute the following command -
sdb connect <ip-address>:<port>
If the remote device is available on the network it will be connected
If you dont have SDB available on your system then you can find it in this -

Now, if you want install or run the application on the remote device may be a TV then you can execute these commands using tizen CLI -
Installing the Application :
tizen install <package file name>
Running the Application :
tizen run -p <appId>
Make sure to execute above two commands, you must have tizen cli available on your system.
